Fire Safety
WARNING: Please read carefully and thoroughly.
•
Life safety from fire in residential occupancies is based
primarily on early notification to occupants of the need to
escape, followed by the appropriate egress actions by
those occupants. Fire warning systems for dwelling units
are capable of protecting about 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 that they cannot escape even when warned early
enough that escape should be possible. For these people,
other strategies such as protection-in-place or assisted
escape or rescue are necessary.
•
Smoke alarms are devices that can provide early warning
of possible fires at a reasonable cost; however, alarms
have sensing limitations. Ionisation 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 smoldering fires) sooner than ionisation alarms.
Home fires develop in different ways and are often
unpredictable. For maximum protection, both ionisation
and photoelectric alarms should be installed.
•
A battery powered alarm must have a battery of the
specified type, in good condition and installed properly.
•
AC powered alarms (without battery backup) will not
operate if the AC power has been cut off, such as by an
electrical fire or an open fuse.
•
Smoke alarms must be tested regularly to make sure
the batteries and the alarm circuits are in good operating
condition.
•
Smoke alarms cannot provide an alarm if smoke does not
reach the alarm. Therefore, smoke alarms may not sense
fires starting in chimneys, walls, on roofs, on the other
side of a closed door or on a different floor.
