Modern homes are currently being constructed with attached and in style garages. Fires that begin at an attached garage can spread easily to the home. Attached garages have to be adequately sealed off from home. It will provide more time during a fire to evacuate to the house.Find additional information at Critical Infrastructure Protection-Sinisi Solutions.
Reasons for hazards from fires:
Heaters and boilers often installed in garages can ignite flame-retardant vapours.
Mechanical or electrical construction projects are often carried out at the garage. Fires can easily begin while an occupant is in the garage doing shop work.
Precautions for Fire safety:
A firewall which extends from the floor to the roof must separate the living space from the garage. The firewall may terminate at the ceiling if the ceiling material is fire-rated.
Sealing or taping of the drywall joints. Joints shall be fitted in such a way that the gap is not greater than 1/20-inch with joints supported either by solid wood or by another layer of drywall so that the joints are staggered.
Any duct work in the adjacent garage must be rigid.
A fire-rated door must be in place which separates the garage from the home. Having at least one step out of the garage leading up to the door is beneficial.
Water heaters should be raised by at least 18 inches above the surface. When the water heater is placed at floor level, a pilot light can ignite flammable fumes and vapours.
All flammable liquids should be stored in approved containers that are labeled and self-closed, and in small volumes. Flame-retardant liquids should be kept away from heaters, appliances, pilot lights and other heat and flame sources.
One should never store propane tanks in garages. If they catch fire, that could result in an explosion. Propane tanks are sturdy enough for outside storage.
Inspection of annexed garages:
The hatch for accessing the attic should also be graded as fire. A hatch cover made of an authorised, fire-rated material will protect this access at all times in garages that have access to the attic.
Home inspectors should call for missing or opened covers, as should coverings made of flammable materials, such as thin plywood.
Ducts in the garage and ducts that reach the walls or ceilings separating the dwelling from the garage shall be built of a minimum sheet of No. 26 gage steel or other permitted material, and shall have no openings in the garage;
Home inspectors will ensure that a curb along the perimeter of the garage floor is present. This form of curbing is designed to avoid fluids flowing into the house’s living areas. Curbs are often useful barriers to melted snow that cars carry into the garage, but the curbs can also keep chemical spills in the garage.
Attached and built in garages should be sealed off the living space so that fire can be contained and occupants are more likely to escape from the home in case of a fire emergency.
