Tempo:
setting minimum door and exit route widths and requiring window egress routes from bedrooms to help occupants escape in the event of fire; and providing clearances around heating and cooking appliances to prevent fires from starting.
Occupants can minimize their exposure to fire risk by:
maintaining smoke alarms in working order; ensuring all occupants are aware of escape routes and of the outdoor gathering point in the event of fire; and exercising care when using cooking and heating appliances.
The requirements for attached housing such as duplexes, houses with a secondary suite, townhouses and apartments are often more complex because a fire in one unit could spread to an adjacent unit without the occupants in the affected unit being aware of a problem.
Space between Houses Fire spreads from one building to another principally by thermal radiation through windows and other unprotected openings. Many things contribute to radiation intensity, and several are more significant than cladding. At any given distance, radiation intensity will primarily depend on the total area of windows radiating heat. The intensity varies inversely as the square of the distance from the source—if the distance is doubled, the radiation intensity will be only 25 per cent that of the original spacing. For this reason, the closer one building is to a property line or an assumed line between two buildings on the same property, the smaller the area of windows and other unprotected openings (such as non-fire-rated doors) is permitted.
The location of a house in relation to a property line can affect the area of openings (windows), the design and construction of overhangs, and the types of exterior cladding materials that are permitted. Restrictions generally apply for houses situated within 2 m (6 ft. 7 in.) of a property line. Consultation with local building officials is recommended before applying for a building permit.
SOUND CONTROL Sound control between rooms of a house is provided by means of the materials used in the floor and wall assemblies and by reducing flanking paths so that noise is not transferred around assemblies. There are no code requirements for additional sound control measures in single-family houses because house occupants can take measures to reduce noise. When a higher level of sound privacy is needed, acoustical insulation can be installed or other measures taken with respect to floors and partition walls. Houses with a secondary suite are required to have a higher level of sound privacy because there could be two separate groups of occupants in one house. Walls and floors between adjacent dwellings must have sound-absorbing materials, resilient channels on one side, and 12.7 mm (1⁄2 in.) thick drywall on ceilings and both sides of walls. If a house is to be built in an area with a high level of traffic or airport noise, an acoustic engineer should be consulted to devise a means to reduce external noise. In multi-family buildings (such as semi-detached or row houses or apartments), sound control measures are required between all dwellings to improve occupant comfort.
