Most damage, deaths and injuries result from smoke
In multiple-death fires in residential high-rise buildings many
fatalities occur in the egress routes (stairways and corridors)
Wind and stack effect exacerbate vertical smoke spread
In cold weather lower-floor fires cause the most smoke spread
to upper floors

Representative Canadian Residential High-Rise Fires*
1981 Toronto Hotel – fire began on 2nd floor of 23-storey building,
significant smoke spread to upper floors caused 6 fatalities
1992 Toronto Apartments – fire began on 9th floor of 25-storey building,
smoke spread to all above floors within 10 minutes and to exit
stairwells causing 1 fatality
1995 Toronto Apartments – fire began on 6th floor of 30-storey building,
rapid smoke spread throughout building resulting in 6 fatalities

Simply complying with the Fire Code does not always provide
optimum fire safety
Egress systems must provide sufficient evacuation time before
smoke reaches lethal levels
Control air leakage and you can limit smoke migration
