FIRE PREVENTION AND PROTECTION FOR THE HOUSE OWNER

Chapter Three: Fire Safety Precautions

General

The most common causes of home fires are carelessness with lighted matches and with smoking, and the misuse of electricity. Some other causes of home fires include faulty television sets, defective heating and cooking equipment, and accumulation of rubbish. Knowing how to recognise a potential fire hazard, along with learning the precautions to take, can save lives and property. The following list is by no means complete - but it does provide an idea of some of the safety precautions that can be taken to reduce the most common causes of residential fires.
Matches and Smoking
  • Use large non-combustible ashtrays. When emptying an ashtray, make sure there is no live ash left in it. Emptying ashtrays into a garbage pail or wastebasket may cause a fire. It is preferable to empty them into a metal container with a tight lid.

  • When discarding a lighted match, hold it for a second or so after blowing it out and then put it into an ashtray, never a wastebasket. Never carelessly toss away a lighted match or cigarette.

  • Never strike a match in, or carry a lighted candle into, closets, attics, or other confined spaces where combustible materials are stored. Use a flashlight.

  • Do not smoke while working near gasoline, oil drippings, or combustible vapours.

  • Never smoke in bed. It is too easy to fall asleep and drop a lighted cigarette. Toxic gases from a fire can render one unconscious before the heat has a chance to waken a sleeper. If you must smoke before going to sleep, it is safer to sit in a chair.

  • Before you go to bed, look under cushions for smouldering cigarettes. If a lighted cigarette is dropped in a couch or easy chair, remove it promptly, and ensure that the lighted end is still attached. If it drops through a crack, do not rest until the cigarette is found, or until certain it cannot smoulder. A heated cigarette end can smoulder for some time before actually igniting the upholstery material.

  • Never leave small children where they can gain access to matches or lighters. In the United States, it is estimated that 200 people die each year in fires associated with cigarette lighters - of these, 140 are children and 125 are under the age of four. In a review, it was disclosed that both boys and girls play with lighters and that children aged three and four can operate them. In fact, some children as young as one and two have used lighters to start fires.

  • Be aware that disposable butane cigarette lighters can be a fire hazard. In fact, defective butane lighters have been proven to be responsible for many injuries and several deaths. They have been known to explode or self-ignite while carried in a pocket as well as during use.

House Wiring and Misuse of Electricity
  • Have a competent electrician repair defective house wiring. Make certain your home is equipped with adequate electrical wiring and an adequate service entrance. If buying a new house ensure it is wired according to your local Electrical Code. Be sure wiring is adequate for such heavy appliances as electric ranges, clothes dryers and air conditioners.

  • Buy only electrical appliances and cords approved by CSA (Canadian Standards Association) - the items should be marked with the CSA logo. Have appliances repaired if they are not working properly - they could be a potential fire hazard.

  • One special hazard may be found in houses that contain wiring made from aluminum rather than copper. Aluminum wiring is safe if it is used with the appropriate devices (such as switches and receptacles) that are designed for it. Overheating and fire can occur if aluminum wire is connected to devices meant for copper wiring. If you are unsure whether your house uses copper or aluminum wire, look inside switch and receptacle boxes - aluminum wire is silvery instead of copper-coloured. If you find that aluminum wiring is installed, check all switches and receptacles to ensure that they are compatible with aluminum wiring.

  • If your service entrance is equipped with replaceable fuses, ensure that they are replaced with the proper sizes and that they are not bypassed. When a fuse blows, or a circuit breaker operates, find the cause of the overload before replacing or resetting.

  • Avoid the excessive use of extension cords and multiple-plug outlets, which increase the chances of overloading electrical circuits. Replace electrical cords of lamps, vacuum cleaners, appliances, etc. if they become worn or otherwise damaged. Do not splice broken or frayed wires and bind them with electrical tape. Do not cover frayed wires or broken insulation with electrical tape. This will result in delaying the proper replacement of damaged wiring, or in forgetting about it altogether.

  • Do not run wires under rugs or over nails, or where they might be subjected to mechanical damage.

  • Disconnect electric irons when not in use. Do not use electric toasters under drapes or near any other flammable material, and keep your eye on anything being toasted to ensure it pops up at the right time and does not get stuck or start burning.

  • Do not leave electric blankets turned on longer than necessary, and ensure that they are turned off while the house is unoccupied. Make sure that the blanket and wiring are in good condition and not worn or frayed in any way. Inspect them regularly.

  • Always remove cords from electric sockets by grasping the plug, not the wire.

  • Have dry hands when using electrical appliances. If an appliance gets wet, have it serviced.

Television Sets and Stereos
  • If the TV or stereo is not working properly, have it checked out - it could be a potential fire hazard.

  • Do not make home repairs on television sets, unless you are qualified to do so. This goes for any other appliance in the home. Fire or shock may result.

  • TV sets and some stereos generate a considerable amount of heat and should have adequate ventilation. Do not obstruct ventilation. Do not place near opened heat vents. Cool air should be allowed to flow in from the direction of the floor, past the ventilation holes in the TV or stereo (where it will be warmed), and out towards the direction of the ceiling. Do not leave television sets or stereos on overnight.

  • If you have a roof antenna, ensure that a lightning arrestor is installed (with an adequate ground). This will prevent damage and fire caused by a lightning strike to the antenna. During a thunderstorm, remove all antenna and cable connections to television and stereo sets.

Heating and Cooking Equipment
  • Furnaces, as well as chimneys and all flues, can be a fire hazard when they are clogged or coated with soot. They should be cleaned at least once a year.

  • Periodically examine gas furnaces, water heaters, fires, etc. and call a qualified gas fitter if there is the slightest indication that there might be a problem. Gas furnaces should have a maintenance inspection periodically. Areas near furnaces should be kept free of combustible materials such as rubbish and paints. If the gas leaks, call the gas company immediately.

  • Gas fireplaces must have the chimney damper permanently secured in the open position. This is a legal safety requirement.

  • Ashes from a fireplace should be placed in a metal container. Keep a metal fire screen in front of every fireplace to prevent sparks escaping.

  • Be sure your kitchen stove is in good repair. Oven, broiler, and burners should be kept free of grease. There should be sufficient clearance between electric ranges and combustible walls. Do not hang drapes, towels, or other combustible materials near or on the stove. Do not store things over the stove as people (and their clothes) can get burned reaching. Keep children away from the stove.

  • Do not preheat the frying pan or cooking oil and walk away unless the burner is turned off and the pan moved to a cool burner. A very greasy broiler tray can catch fire if it is preheated, especially if excess fat has not been trimmed from the roast. If the oven (and broiler tray) needs cleaning, don’t cook in it. Clean the oven at least once every six months.

  • If you have a gas stove, never leave the house with it lit. Be sure the pilot light works properly. Wear tight sleeves when you cook as loose-fitting garments can catch fire. Tie up long hair.

  • Turn off portable oil or gas heaters before retiring and before going out. Do not place portable heaters where they can easily be tripped over or overturned. They should be kept at least 0.9m (3 feet) from combustible materials, such as bedding, drapes and furniture, and away from areas where children play.

  • Never throw flour or dust from a vacuum cleaner or dustpan into an open fire. Dust is explosive - wrap it up and dispose of it safely.

  • If your blow dryer stops automatically under normal conditions, it is a warning that the unit is overheating and could become a fire hazard. Unplug the dryer and remove all hair, dust and lint from the dryer vents before trying the dryer again. Unplug your blow dryer, curling iron, styling brush, etc. when not being used. Make sure the appliance is cool before storing and do not wrap the cord around the appliance.

Utility, Workshop and Garage Areas
  • Keep your clothes dryer in good working order and operate it in strict accordance with the manufacturers instructions. Make sure the lint tray is in place before using and clean it out regularly (preferably after every use). Lint and some types of anti-static sheets can become a fire hazard if they get too close to the motor.

  • In the workshop, install enough electrical outlets, properly fused and in accordance with your local electrical codes, to eliminate the need for extension cords.

  • Store gasoline and other flammable liquids in tight metal containers. Do not store these, or propane cylinders, in the house. Do not use flammable liquids near heat, a pilot light, or while smoking.

  • Clean up gas and oil spills in the garage or carport and either dispose of oily or greasy rags or keep them in a sealed metal can. Old paint cans should be discarded. Clean up sawdust immediately and discard away from the house.

  • Paint, paint removers and solvents, if they must be stored in the house, should be stored in tightly closed metal containers. Use these liquids only in an area that is well ventilated (preferably outside).

Outdoors
  • Propane barbecues must be kept away from the house at all times (in use and while stored). They can turn into giant blowtorches if the proper precautions are not taken. Before lighting, ensure that all gas fittings are properly tightened and do not leak. For further information on the safe use of propane appliances refer to Chapter 4.

  • Do not use gasoline on a grill or barbecue fire ever. Once the fire has been started, never use lighter fluid either. Use dry kindling to revive the fire.

  • Move the lawnmower (gas or electric) away from gasoline fumes before starting. Cool motor before refuelling gas lawnmower.

  • Stacks of old newspapers should be removed. Find a school or organisation that is collecting newspapers for recycling.

  • Clean up the dead leaves in the yard, also any fallen branches or limbs. Remove broken glass and discard all piles of rubbish.

  • Check the outside of the chimney for signs of cracks and inspect the chimney flue for creosote build-up.

  • If backyard burning is allowed in your area, watch fires constantly and extinguish with water before leaving. Never allow children to play near outdoor fires or barbecues.

Christmas
Throughout the year, there are infrequent occasions where special precautions need to be taken with regard to fire safety. One such occasion is Christmas, when a decorated tree and Christmas lights bring a special warmth to the holiday season, and people are usually so caught up in the spirit of Christmas that they often overlook the most basic safety precautions. Each year tragedy strikes somewhere through electrical fires or other accidents, often caused by worn or defective equipment, or by sheer negligence. Proper selection and placement of the tree, together with the following of proper electrical practices, is essential to ensure adequate fire safety in the home at Christmas time.
Christmas trees You may choose a real or an artificial tree but, whichever type you do use, keep it away from any potential source of heat or flame (such as the fireplace or TV), and do not use candles on or near the tree. Do not allow discarded gift wrappings or other combustible materials under the tree and use only non-flammable decorations on the tree. Do not allow the tree to block fire escape routes.

Real Christmas trees: Cut Christmas trees become extremely flammable when cut long in advance of use, and when brought indoors where heat and low humidity accelerate drying. To reduce the hazard, the tree (if you feel you must use a real one) should be kept indoors only as long as absolutely necessary. The trunk should be sawed off at an angle at least 2.5cm (1-inch) above the original cut end and kept standing in water during the period the tree is in the house. Water should be added at intervals to keep the water level above the cut. There are Christmas tree stands available that are specially designed for cut trees, having a water-filled base and often including a safety reservoir for added protection. Fire retardants do not work well on Christmas trees and are not recommended as a means of fire protection. Live Christmas trees (those with roots) are safer than cut ones, providing they are watered regularly. Always dispose of a cut Christmas tree promptly after the holiday season - do not keep it in the house. Live trees should be transplanted outside as soon as possible.

Artificial Christmas trees: Only purchase an artificial tree that is labelled "non-flammable" or "fire-resistant" on the tree or on the box.

Christmas lighting Always look for the CSA Certification Mark when buying new lights, lighted displays or extension cords. The lights may be either of the indoor or outdoor type, so ensure that you purchase the correct type for the purpose intended (indoor types should not be used outdoors). Always check old lighting sets before installing them - visually inspect them for worn insulation, broken plugs or loose bulb sockets and replace missing bulbs. Plug the lights in and confirm operation - replace any bulbs that do not light and do not install the set until all lights are working properly (this is particularly important with series strings where burned-out bulbs are often bypassed, increasing the voltage on other bulbs). When replacing burned out bulbs, always unplug the set from the wall socket first, then make sure the replacement bulb is the correct type and voltage (CSA requires that packages of replacement bulbs bear guidelines to assist in the selection of the correct bulb). The CSA also requires that the package of lighting sets must indicate the number of sets that can be safely strung together or operated from a single wall socket - if this warning is ignored, a fire hazard could be created. On outdoor displays the sockets must be hung with the bulb pointing downward - use only insulated staples to hold the strings in place, or run them through hooks. Do not overload electrical sockets or extension cords and do not run cords where they can be tripped over. Always switch off tree lights at bedtime, or when leaving the house.
Halloween
Another infrequent occasion when special precautions need to be taken with regard to fire safety, is Halloween. Here the danger is from loose flowing costumes, candles and fireworks.
Costumes Halloween costumes may be made at home, purchased or rented. They are often loose-fitting and flowing in accordance with the Halloween tradition of witches, goblins and ghosts. At this time of year, when open fires and candles are common, proper selection of costume material and design, as well as extra special care by the wearer, is essential in reducing the risk of fire injury. Do not allow costumes to be more loose-fitting and flowing than absolutely necessary and do not cook or perform tasks near open flames or candles wearing such apparel. In particular, children’s costumes should be made of fire-resistant material or be treated with a fire retardant. Many plastic outfits are so marked. Refer to the sections on textiles and clothing below for selecting flame-resistant costumes or materials made of textile fibres. In addition, for wearing outdoors, "trick-or-treat" costumes should also be reflective or bear reflective markings visible from all directions.
Candles Placing candles in carved pumpkin heads is a Halloween tradition, but many serious fires have been caused by carelessness in placing and lighting the candle. To reduce the hazard, ensure that the candle is placed in a stable, upright position within a pumpkin that is still moist (i.e. one that has not been allowed to dry out). It is recommended that the candle be placed in a holder of some kind. Place the pumpkin on a stable base well away from drapes and any other loose-flowing or flammable material. Do not leave a pumpkin with a burning candle unattended inside the house - pets may knock over carelessly placed pumpkins, especially when spooked by the loud and strange sounds of Halloween. Light the candle with a long match or spill, preferably through one of the eyes of the pumpkin rather than through the top to prevent burning yourself or your clothing. Do not move the pumpkin with the candle lit, and always ensure that all candles are properly extinguished before going to sleep.
Fireworks Conservative current estimates indicate that possibly 10 deaths and 4000 injuries are caused by fireworks each year in North America. In addition, many cases of property damage are reported. According to the National Fire Code of Canada, the manufacture, storage, transportation and sale of fireworks must conform to the "Explosives Act" and the "Explosives Regulations", as administered by the Explosives Branch of Energy, Mines and Resources Canada. In the Regulations, explosives are divided into seven classes, Class 7 being the fireworks class. Amongst other requirements of this section, it is stated that no person shall knowingly sell any firework (with the exception of caps for toy guns and model rocket engines) to a person who is under the age of eighteen, or who appears to be under the age of eighteen and does not produce evidence that he is of the age of eighteen or over. The NFC also states that the handling and discharge of fireworks shall conform to the "Manual of Display Fireworks", as published by the Department of Energy, Mines and Resources. In addition to these federal regulations, the provinces and municipalities may have their own specific regulations governing the sale and use of fireworks.

Firework Regulations: Class 7 of the Explosives Regulations is divided and subdivided to cover the various types of fireworks as defined in the regulations Class 7.2.1 refers to low-hazard "family" fireworks used for recreation (e.g. small fountains, volcanoes, Roman candles, pin wheels, sparklers, Christmas crackers, caps for toy guns). Fireworks of this class will not explode violently and may be sold to an adult for his own use and enjoyment - he bears the responsibility for their safe use by himself and his family. Class 7.2.2 refers to high-hazard fireworks used for public displays (e.g. rockets, large wheels and bouquets, fountains, batteries, candles, mines, firecrackers). Fireworks of this class present a special hazard and usually require a permit for their purchase and display. High-hazard fireworks must not be kept in private homes, apartments or any type of dwelling.

Firework Safety: With the exception of sparklers, no fireworks are designed to be, or should be, held in the hand when lighted. As fireworks are a potential fire and health hazard, always read the instructions on each item carefully before using. Other safety tips for a family fireworks display are given below:

  • Select a firing site free of overhead obstacles such as trees and wires, and away from combustible materials and substances, including houses and wooden fences.

  • A large water container should be kept at the firing site for safety and to dispose of used fireworks. A hose, connected and ready for using, will provide a measure of added safety.

  • One adult should be in charge of the display. Young children should not participate in the firing, but older children may help one at a time under close adult supervision.

  • Read all instructions thoroughly, using a flashlight or electric light - never an open flame.

  • Implanted fireworks must be secure. Buckets, boxes and wheelbarrows filled with earth or sand make a good firing base. Set fireworks at a 10 degree angle away from spectators and pack earth or sand around them firmly so that they will not fall over during the display. Long pieces should be buried to half their depth.

  • Glow ring igniters are recommended for lighting safety (although sparklers have to be started with matches or a lighter). Keep all spectators clear of the firing area while lighting the fuse and step back to a safe area quickly once the fuse is ignited.

  • Do not approach a used firework or a firework that has not gone off until you are sure it is safe to do so. Do not attempt to relight a piece that has not gone off.

Power Failures
In the event of a power failure, use candles and gas lanterns wisely. Candles should be placed in a proper holder, secured in an upright position and not be placed where they may be knocked over - they should not be carried while lit. Do not use open flame devices in a closet or near flammable materials or substances. Use a flashlight where-ever possible. Use camping equipment (such as camp stoves) outside and away from the house. It is recommended that you purchase one or more power failure lights as described in Chapter 8 and place them in areas where they will be most useful in the event of a power failure (e.g. to illuminate a hallway or stairway).
Textiles
Textiles are an intimate part of daily living. The clothes we wear, the chairs we sit on, the carpets we walk on and the beds we sleep in are examples of textiles used regularly in the home. Most textile fibres will burn, and the presence of flame near a flammable fabric of open or airy construction has in the past been sufficient to start tragic fires. Careless smoking has been responsible for many deaths caused by burning bedding and upholstered furniture, while spread of fire has resulted from flaming carpeting (lateral spread) and draperies (vertical spread).

Selection of textile products for the best fire rating is not an easy matter. To properly determine the fire hazard rating of a particular fabric, it is necessary to know the ease of ignition, surface flame spread, heat release, smoke obscuration and toxicity of combustion products. It is difficult, if not impossible, to obtain such ratings from dealers or manufacturers that will allow the consumer to select a textile product for fire safety. The many factors affecting the fire hazard rating of a textile product include the type of fibre used, whether the fibre is blended, the construction of the fabric, the design of the product, the type of filling material and the type of dye used. In addition, various chemicals may be applied to the fibres or to the fabric to add flame resistance to normally flammable materials - it should be noted, however, that the use of phosphate detergents, fabric softeners and bleach may render the flame-retardant finish ineffective after a number of washings). The Canadian consumer is protected to a degree by the Hazardous Products Act, which is administered by the Products Safety Division of the Department for Consumer and Corporate Affairs. This act requires that clothing and certain textile products meet specified standards of flammability. More detailed information on finished products can be found in the sections on clothing and furniture and furnishings below.

The following table provides a list of some of the basic fibres and their reaction to flame. The list does not consider the affect of dyes, blending or chemical finishes on the fabric.

Clothing
The worst burns usually involve clothing. Every year many deaths and severe injuries are attributed to peoples clothes catching fire. It happens especially to children and the elderly and, in most cases, the victims are dressed in sleepwear. Usually, it is the children’s innate sense of curiosity that gets them into trouble - they have come across a lighter or a book of matches, or they have managed to come too close to a fireplace or the hot element of a stove. In the case of adults, their clothing most often catches fire while they are cooking, smoking or handling combustibles.
Fabric composition Clearly, any article of clothing (unless it is made from asbestos) will burn once it contacts a source of ignition. However, there are certain types of fibres and fabrics that are less likely to ignite than others, and some that will burn more slowly, reducing the risk of a serious injury. For clothing use, we are not as concerned about the toxicity of fabrics when burning as we are in the ability of the fabric to self-extinguish once the ignition source has been removed (so that, if a person trapped in a fire can get clear of the fire, his clothing will stop burning). Fabrics made of synthetic or protein fibre will do this, as will cellulistic fibres that have been treated with a fire-retardant. The problem with synthetic fibres is that they tend to melt in or near flame, increasing the severity of burns. Some clothing fabrics made of mineral fibres are non-flammable.
Garment design and construction In addition to the type of fibre, fabric construction and finish as described above, the design and construction of the garment itself is important in reducing the fire hazard. Tests on sewn garments reveal that sewing threads can burn, causing ignition and burning in otherwise flame-retardant fabrics. Trimmings can have an even more pronounced effect. Long sleeves, flowing clothing and shirttails are very dangerous around stoves, barbecues and open fires. In some cases, a child or adult could be engulfed in flames in 30 seconds. Snug-fitting garments with tight waists, ankles and wrists are safer, as are tailored, fitted garments. They are less likely to contact ignition sources, and will burn slowly because the amount of oxygen available to feed the fire is limited. Victims, or those closeby, will have more time to react to smother the flames and limit the injury.
Regulations for children's sleepwear The Minister of Consumer and Corporate Affairs has recently introduced more stringent flammability regulations for children's sleepwear in order to reduce the incidence and severity of sleepwear burn injuries. The flammability of children's sleepwear up to size 6X has been regulated under the Hazardous Products Act since 1971. Despite this regulation, a minimum of 21 children under the age of 9 were severely burned and one or two died each year due to sleepwear fires. The new regulations, made effective in 1987, apply to sleepwear which have been implicated in the most severe injuries (such as children’s night-gowns, night shirts, dressing gowns, bathrobes, housecoats and robes, pyjamas and babydoll pyjamas in sizes up to and including 14X). Less hazardous styles of sleepwear, such as polopyjamas and sleepers, remain subject to the existing regulations. For an item to comply with the new regulations it must, among other requirements, pass a flame resistance test. Very briefly, the test consists of igniting the ends of five test specimens of the fabric 3-1/2" wide by 10" long. For the material to pass, the average char length for the five specimens must not exceed 7", and not more than one individual specimen is allowed to have a char length equal to the full length of the specimen (i.e. 10").
Safety tips To reduce the risk of a clothing or sleepwear fire adhere to the following safety tips:
  • Consider the age, physical condition and mentality of the wearer, as well as the burning properties of the fibres and fabric, when evaluating the fire hazard potential of clothing.

  • When buying or making clothes or sleepwear choose fabrics that are difficult to ignite, slow to burn, are self-extinguishing when the ignition source is removed and do not melt readily. Also select fabrics with a tight weave (such as denim and double-knits) that will limit the amount of oxygen that is able to flow through the fabric to fuel a fire should the fabric ignite.

  • When buying or making clothes or sleepwear choose designs that fit snugly (i.e. are not long and flowing) so that the amount of oxygen available to fuel a fire from both sides is limited. For example, jogging suit styles of pyjamas are usually best for children's nightwear.

  • Keep matches, lighters and open flames out of the reach of children.

  • Do not allow children to play near or climb on stoves, fireplaces or other heat sources.

  • Do not wear loose-fitting garments when cooking or around fires, barbecues, or other heat sources.

  • If you buy or make clothes that incorporate a flame-retardant chemical, ensure that you follow the laundering instructions exactly.

House Construction
There is probably little one can do about changing the existing construction of a house to improve the fire safety requirements - the cost would be prohibitive (except for maybe upgrading existing wood doors as described in the section on interior wood doors). However, if you are having a house built, or are renovating or adding to an existing building, you may be able to ensure that the best possible protection is achieved. The first obligation of house designers is to meet the legal requirements of the National Building Code of Canada (NBC) and the National Fire Code of Canada (NFC). These codes are complementary. Together they contain the fire safety requirements for all buildings in Canada, and specify recognised fire and safety standards for building materials (such as CSA and ULC) by reference. In addition to the federal codes, provincial and municipal building and fire codes must be met. Additions and renovations must also comply with the building codes, hence the necessity for obtaining a permit before such construction can commence.
Construction materials The structural framing of a building has little to do with the hazard from fire to the occupants. Most fires start in the building contents and create conditions that render the inside of the home uninhabitable long before the structural framing becomes involved in the fire. However, once the fire starts in the contents, the material of which the building is constructed can be of significant help in facilitating evacuation, fire fighting, and property protection. ULC have a series of standards for determining the non-combustibility of building materials, and these are referenced in the National Building Code of Canada.
Wood construction The gypsum board used commonly in residential construction, in combination with the wood-frame construction, inherently provides a fire endurance of at least 20-30 minutes in the worst case of a fully-involved fire. When exposed to fire, wood forms a self-insulating surface layer of char, which actually provides its own fire protection. Even though the surface chars (at an average rate of one inch in approximately 40 minutes), the undamaged wood underneath retains its strength. For this reason, heavy timber is often recommended for load- carrying wood members in order to attain an added measure of fire resistance. To lower the rate of surface flame spread and make the wood self-extinguishing if the external source of heat is removed, fire retardant chemicals may be impregnated in the wood. However, such chemical treatment is very expensive and probably not worth the extra cost for the amount of added protection it affords your property.
Preventing the spread of fire Common construction methods are designed to prevent the spread of fire both horizontally and vertically in building interiors. Horizontal protection can be improved by using fire-resistant Type X gypsum wallboard covered with latex paint (which is less flammable than oil-base paint), using properly constructed and fitted interior doors (see the section on interior wood doors below), keeping unused doors closed, and carefully selecting wall coverings (see the sections on wallpaper and paint below). Vertical protection can be improved by using Type X gypsum wallboard covered with latex paint for the ceiling and firestopping any openings between floors. Blocking and sill plates can be placed horizontally between the studs at floor, ceiling and intermediate levels to interrupt the updraft between the walls that would otherwise carry fire, smoke, heat and toxic fumes to the upper storeys and to the roof. Openings around furnace chimney pipes, etc., should be properly filled, and stairways can be firestopped by using properly constructed doors (although this may not be possible with open stairways).
Fireplaces and chimneys Chimneys should extend above the highest point of the roof and be solidly constructed with flue linings of fire clay or other approved insulating material. Unused flue holes should be safely closed with a non-combustible cap, not papered over or left open. Joists should not extend into the chimney. Fireplaces should be safely insulated with approved non-combustible material.
Wallpaper Many synthetics (such as vinyl wallpaper) release smoke and toxic fumes when burned. One company has changed that liability into an asset by changing the composition of its vinyl wallcoverings so that they warn of impending fire even before either smoke or flame appear. The new early warning wall coverings, when heated to 149 degrees Centigrade (300 degrees Fahrenheit), release a harmless, odourless and colourless vapour that activates ionisation-type smoke detectors. This temperature threshold is well below the ignition point of many common materials, including paper, cotton and plastic foams. Officials of the manufacturing company say that the new wall covering will be especially useful in detecting electrical overloads and shorts that cause fires inside walls.
Paint Fire-retardant paints are available that will slow down the spread of fire inside a house by puffing up into a foamy insulating layer when exposed to high temperatures. The insulation helps keep the paint from flaring - as most conventional paints will do - and also temporarily prevents flammable material underneath, such as wood studs and joists, from reaching the kindling point. This type of paint is known as intumescent paint and is particularly valuable in garages and basements. It is usually only available in flat latex and can be applied over any surface that is suitable for conventional flat latex paint. However, conventional paints should not be applied over intumescent paint because they impair its effectiveness. For maximum effectiveness, it is important to follow the manufacturers instructions exactly.
Interior wood doors Interior doors should be kept closed when not being used, especially at night when the occupants are sleeping. This affords a measure of delay to fire, smoke, heat and toxic fumes. The length of delay, required to allow the occupants of the room to awaken and escape, is dependant on the construction of the door itself, the door frame and the fit of the door within the door frame. Solid core doors are the best protection, but are seldom used in the interior of normal residential homes. The fire resistance of existing hollow and wood panel doors within the home can be improved by adding 1/2" gypsum wallboard or plywood to the room side of the door. For full details on performing this modification contact your local Provincial Fire Commissioner’s Office.
Lightning protection The probability of a building being struck by lightning and the resulting risk of loss can be calculated based on the type of structure (e.g. single family residence less than 5000 sq. ft.), type of construction (e.g. wood framework with composition roof), relative location (e.g. a small structure in the area of higher structures), topography (e.g. on flat land), occupancy and contents (e.g. residential furnishings), and the lightning frequency (based on the mean annual number of days with thunderstorms for the area in question). Based on these factors for a single family residence in Canada, the risk of loss from lightning will be relatively light. Consequently, such residential buildings will not normally require lightning protection. As well as direct and indirect lightning strikes to the building itself, any metallic object protruding from the building (such as overhead cables or an antenna) are subject to strikes. Utility companies (such as power, telephone and cablevision) are required to install lightning protection arrestors where the cables enter the building. If you have a television antenna, or any other form of antenna, placed on or near your house, it should have a lightning protection system with an acceptable ground.
Fire protection equipment If you are buying or building a new house, it is recommended that you have installed, during construction, either an ac powered system of smoke detectors wired for multiple operation (see here), or a complete hardwired burglar/fire alarm system (see here). The detectors must be located and mounted per the recommendations given here and here. Heat-activated and gas alarms should be installed as recommended here and Section 4.4 respectively. You might also consider installing a quick-response residential sprinkler system (see Section 7).
Furniture and Furnishings
Attempts to improve fire safety through building code requirements have been continuing for many years, but they affect only the design and construction of the building itself. It is a fact that house furnishings play an even greater role in fire safety, as these are most often the items that ignite first and also pose the greatest immediate threat to life. In about 33% of the residential fire deaths reported in Canada, furniture and furnishings were identified as the articles first ignited. Over 80% of these items were upholstered furniture, bedding and mattresses, and 80% were caused by carelessness with smoking materials. Curtains, drapes and carpeting were mainly responsible for the spread of fire. It can be seen from these statistics that a substantial reduction in the number of fire deaths is possible by improving the ability of furniture and furnishings to resist ignition from small sources such as cigarettes and matches.
Bedding Burning bedding (mattresses, sheets, blankets, pillows, etc.) results in approximately 46% of the fire deaths caused by carelessness with smoking materials. In many of these cases, the fire smouldered during the early stages at least, and the victim was killed by the fire gases rather than by burns. To reduce the fatality rate, products made in whole or part of textile fibres and designed for use on a pillow, or on a bed, cot, crib, or other furniture designed to be used for sleeping, are regulated under the Hazardous Products Act. Under this Act, mattresses have to pass a test that involves placing a lighted cigarette on the mattress assembly and ensuring that either (a) combustion of the mattress does not proceed further than 50mm (2 inches) from the original location of the cigarette or (b) that combustion ceases within ten minutes after the cigarette is extinguished. As people in bedding fires are more likely to die from inhalation of toxic fumes rather than from burns, it is better to choose items of bedding that are less toxic rather than less flammable. Synthetic fibres generally give off more toxic fumes when burning than do natural fibres. Because it is difficult to pin down the requirements for bedding fabrics, and because specifications of toxicity are not easy to comeby, it is recommended that the following safety tips be strictly adhered to:
  • Do not smoke in bed.

  • When buying or making bedding, choose fabrics and filling material made of fibres that are difficult to ignite, slow to burn, are self-extinguishing once the ignition source is removed, and do not give off excessive toxic fumes when burning.

  • Keep any heaters or possible ignition sources at least one metre away from the bed. When removing bedding from the bed keep it at the same distance.

  • Keep matches, lighters and open flames out of the reach of children.

  • Install a smoke detector in the centre of the bedroom ceiling.

  • If you buy or make bedding that incorporate a flame-retardant chemical, ensure that you follow the laundering instructions exactly.

Upholstered furniture Because many materials used in upholstered furniture burn rapidly and emit toxic gases, burning upholstery results in approximately 43% of the fire deaths caused by carelessness with smoking materials. Concerns about home fires caused by smouldering cigarettes prompted various groups interested in public safety to request action by the federal government. As a result of subsequent discussions, a voluntary industry program to test the flammability of upholstered furniture was approved by the federal government. In 1986 the Canadian Council of Furniture Manufacturers (CCFM) signed a formal agreement with the Upholstery Furniture Action Council (UFAC) in the U.S. to develop, in Canada, a voluntary initiative similar to the one in place in the U.S. since 1979. The UFAC program includes fabric classification, construction criteria, labelling and compliance procedures. The UFAC uses a hangtag, which assures consumers that the item bearing the tag is safer because it is made in accordance with the UFAC-recommended construction criteria. It also warns the consumer of the dangers of ignition by a burning cigarette regardless of the improvements of UFAC criteria. The distinctive UFAC hangtag, which will become an increasingly common sight in Canadian stores, is shown in Figure 3. For further information on the UFAC voluntary action program contact the CCFM.

Whether you buy new furniture with the UFAC label or whether you continue to use your existing furniture, take special precautions if you have a smoker in your household, or frequent visitors who smoke. For example, it is advisable to select a "smoking" chair or couch which has few, if any, areas where a cigarette may lodge and burn. It is particularly important to avoid crevices where back, side and seat areas join. For this reason, separate seat cushions should be avoided, as should seams used across the seat area that may tend to pull loose under heavy use, exposing the inner filling to possible ignition from a cigarette.

Window coverings Curtains and drapes are words to describe two different types of window coverings. Curtains usually hang in front of the window, often above the sill and inside the frame. Drapes, on the other hand, usually extend outside the window moulding and may extend all the way from the ceiling to the floor. These items, but particularly drapes, can be the prime material involved in the vertical spread of fire in a residential building. It is important to note that shaggy or loosely constructed fabrics encourage the spread of fire, whereas smooth, closely constructed fabrics resist flame spread. To reduce the risk of a fire in curtain and draperies adhere to the following safety tips:
  • When buying or making curtains and drapes, avoid purchasing shaggy or loosely-constructed fabrics. Instead, choose smooth, closely-constructed fabrics which are more likely to resist the spread of flame.

  • Keep any heaters or possible ignition sources at least one metre away from curtains and drapes.

  • Keep matches, lighters and open flames out of the reach of children.

  • If you buy or make curtains or drapes that incorporate a flame-retardant chemical, ensure that you follow the laundering instructions exactly.

Floor coverings Carpets used to be a significant contributor to the lateral (horizontal) spread of a fire - mainly because flammable fibres were used in the carpet pile. But, since the advent of regulations under the Hazardous Products Act and with the stringent requirements of the Canada Mortgage and Housing Corporation (CMHC) and the National Building Code, residential carpets are no longer considered a major contributor to the spread of fire from a small fire source. Since the regulations were introduced, there have been many examples of residential room fires where furnishings were badly damaged and the carpet remained intact. This has been accomplished by eliminating the most hazardous fibres, treating other fibres to make them flame-resistant, adding flame retardants to the latex adhesives in the carpet backing, and improving the non-flammable properties of underpads. Thus, any carpet currently available to the Canadian consumer will offer similar and adequate protection against fire spread in a residential home.
Wood Burning Heaters and Stoves
Many fires have been attributed to the use of solid fuel, which is now showing increasing popularity as an alternative heat source in this age of energy conservation. If you are considering installing a wood-burning appliance, keep your family’s safety and your homeowners insurance policy in mind. Although wood-fired appliances are not currently required by law to be certified, it is highly recommended that you purchase one that is. In fact, any solid fuel burning appliance that you buy should bear a certification mark (such as CSA) and be installed according to the CSA Installation Code for Solid Fuel Burning Appliances and Equipment (CAN3-B365-M84).
New installations For proper selection and installation of a wood-burning appliance, use the following guidelines:
  • Look for the certification mark on the label affixed to the appliance.

  • Before buying the unit, advise your insurance agent that you are thinking of installing a wood-burning appliance - it could void your insurance or affect your premium.

  • Contact your municipality and ask if a building permit is necessary.

  • Make sure the installer is using the CSA Installation Code.

  • Ask your local or municipal building or fire inspector to check the installation before using it.

  • Ask your insurance agent to update your insurance policy.

Existing installations If you already own a wood-fired appliance, take the following precautions:
  • Check for a certification mark on your appliance, located near the manufacturer’s nameplate.

  • Have your installation checked by your local fire or building inspector, or by a reputable retailer/installer who uses the CSA Installation Code.

  • If there are any installation deficiencies, have them corrected or the unit reinstalled properly.

  • Call your insurance agent to advise him that your wood-burning appliance meets the CSA Installation Code requirements.

Maintenance and use Maintenance of your certified and properly installed wood-burning appliance is also essential to its safe and efficient use:
  • Always make sure your stove pipes and chimney are in good condition and check them regularly for creosote build-up. Shiny creosote deposits which look like black paint are an indication that your wood -fired system is not working properly. Call a chimney sweep for help.

  • Burn seasoned wood to minimise creosote build-up. Wood which is cut, split and stacked under cover to air dry in the spring will be seasoned and ready for burning in the fall. Longer storage times, however, are preferable.

  • When a wood furnace is the sole heat source, ashes must be removed at least once a week. Used as supplemental heating, it may require emptying once a month. The ashes, once removed, should be placed in a metal container and stored outside, away from any combustible material.

  • During and after the heating season, check that the hinges, doors, latches, gaskets, and operating controls of the appliance are functioning properly.

  • Do not load the appliance with too much wood. This can cause the wood to smoulder which, in turn, contributes to excessive creosote build-up.

Fire-resistant Containers
Large amounts of cash should never be kept at home - neither should valuable documents (such as bonds, shares, certificates and insurance policies), unused jewellery, coin and stamp collections, and other items of value. Financial institutions and private vault firms can offer far greater protection from fire and burglary than can ever be attained in your home. However, there may be some items of value that you feel you must keep at home. These items should be protected against fire and theft. Unfortunately, safes that provide the best protection against burglary do not necessarily provide the best protection against fire damage and vice versa.
Types of safes The type of safe that will resist burglary attempts will make things tough for thieves trying to break through the box, but the steel - and often copper - walls are excellent heat conductors that can quickly bring interior temperatures up to incendiary levels when exposed to fire. Fire-resistant safes, on the other hand, afford protection against heat, smoke and flame for your records and documents, but offer only minimal security against the skilled burglar with tools. Safes offering a combination of construction and materials that will protect against both fire and burglary attempts are available, but these are often too expensive for the average homeowner. The best compromise is probably to find a good quality fire-resistant safe, because these do offer some degree of theft protection, whereas burglary-resistant safes often offer little in the way of fire protection.
Requirements for a fire-resistant safe Standards for the classification of fire-resistant safes have been written by a number of organisations around the world. For example, certification services are provided by JIS in Japan and UL in the U.S. In Canada, the degree to which an insulated safe is affected by fire and heat (i.e. the quality of the product) is determined by the results of three ULC tests. Once these tests have been successfully completed, the safe will be listed under the Label Service of the ULC and will bear the ULC logo, together with one of three classification levels. The tests required for each classification level are given in the following list - they ensure that paper inside the safe will not ignite and will remain pliable and legible at the various degrees of exposure to heat. The highest classification level is Class 177C-4h, followed by Class 177C-2h and Class 177C-1h.

Fire Endurance Test: The safe is exposed to an external source of heat (applied per classification level) before an internal temperature of 177é Centigrade was reached (as measured 150mm from the top and back of the interior, and 25mm from the side walls and door).

Class Exposure level Period
177C - 4h 1093º C 4 hours
177C - 2h 1010º C 2 hours
177C - 1h 927º C 1 hour

Explosion Hazard: The safe is exposed to a sudden heating of 1093é Centigrade for 30 minutes without producing an explosion sufficient to cause an opening into the interior. This is the same for all classifications.

Fire Impact Test: The safe is heated (per classification level), dropped 9145mm (30 ft.), then reheated (per classification level) in the inverted position. It must remain intact and the papers inside must still be usable after the test.

Class First Exposure Second Exposure
Level Period Level Period
177C - 4h 1093º C 1 hour 1093º C 1 hour
177C - 2h 1010º C 45 minutes 1010º C 30 minutes
177C - 1h 927º C 30 minutes 927º C 30 minutes
Selecting a fire-resistant safe Safes come in a wide variety of sizes, types, grades and prices. To ensure adequate protection in the event of a fire, it is recommended that the product be ULC-listed and bear the ULC logo (or, at least, be rated by one of the world-wide classification services). A safe rated Class 177C-1h by the ULC should be adequate for normal residential use and a fair bit cheaper than one with a higher rating. To select the required size, gather up everything you want to protect, put all of it into a cardboard box, and measure the space the things take up.
Special Precautions for the Physically Disabled
Many people have physical disabilities that present special problems with relation to fire safety - they may not be able to hear the sound of a fire alarm or respond to the warning and escape as easily as a non-handicapped person. It is important to immediately notify your local fire department that there is a disabled person in your household and the nature of the disability. Many fire departments have established programs to register people with special needs and, in the event of a fire, this information could help the fire-fighters ensure that all occupants are evacuated safely.
The deaf or hearing impaired person Public fire safety programs are essentially structured around the need of individuals who can hear. However, there are over 2.2 million hearing impaired Canadians. Hearing loss can vary from a mild loss to profound deafness. There are technical aids available that are designed to help the hearing impaired person cope with daily living. These include devices that will ensure a person with a hearing loss is warned in the event of a fire alarm or will allow them to communicate with the fire department. Fire alarm signals for the hearing impaired are discussed in Section 5.3.9. Because communication is vital in an emergency, be sure that your home is equipped with an amplified telephone handset or a Telephone Device for the Deaf (TDD). Install one or other of these devices in a location that can be easily accessed by that person in the event of an emergency and place a list of emergency numbers on or near the device. Some TDDs can be pre-programmed with a message for the fire department. For more information on technical aids for the person suffering from a hearing loss contact the Canadian Co-ordinating Council on Deafness.
