half of the occupants in potentially fatal fires. Victims are often intimate
with the fire, too old or young, or physically or mentally impaired such

smoke alarms be installed to help ensure maximum detection of
the various types of fires that can occur within the home. Ionization
sensing alarms may detect invisible fire particles (associated with
fast flaming fires) sooner than photoelectric alarms. Photoelectric
sensing alarms may detect visible fire particles (associated with slow
smouldering fires) sooner than ionization alarms.
