smoke alarms: What you need to know
- Daylight Saving Time
- Change Your Batteries in your
SMOKE ALARMS
-
- If
you haven't changed your batteries in your smoke alarms during the last
year, do
- so
now. There have been a number of home fires occur where the smoke alarms had
- no
batteries or had dead ones. If you need advice on how many smoke alarms you
- need,
or where to place them, ask any firefighter.
-
- Most fatal home fires
occur at night when people are asleep. Instead of waking
- you,
smoke and poisonous gases from a fire quickly numb the senses and put you
- into
an even deeper sleep. Seconds can make the difference between life and
- death.
Are you and your loved ones protected? Smoke alarms that are properly
- installed,
maintained and tested in the home
can save lives.
-
- What does a smoke alarm do? The purpose of a residential smoke
alarm is to
- sense
the presence of smoke in the home, to sound an alarm and alert the
occupants,
- giving
them time to escape.
-
- What types are available? There are two main types: Ionization
and Photoelectric.
- Ionization
smoke alarms contain a small chamber that produces electrically charged
- air
molecules called ions. When smoke enters the chamber, it causes a change in
the
- flow
of ions, triggering the alarm.
- Photoelectric
smoke alarms contain a light source whose beam is deflected by
- smoke
into a photo-cell, thereby causing an alarm to sound.
- Both
types provide effective protection. Smoke alarms can either be wired into
the
- household
electrical system or be battery operated.
-
- Other Options Available Include: Models which have a reset
button.
- Models
incorporating an emergency light.
- Models
for the hearing-impaired that flash a light in addition to sounding an
alarm.
-
- How
many do I need? A smoke alarm in each sleeping area and on each level of the
- home
provides a reasonable degree of protection from the threat of fire.
- Smoke
alarms are not recommended for kitchens, bathrooms or garages, where
- cooking
fumes, steam or exhaust could set off false alarms.
-
- How
do I install my smoke alarm? If you can handle a screw-driver and operate a
- drill,
you can install a battery-operated smoke alarm. They are simply fastened
with
- two
small screws.
- Because
smoke rises, mount alarms on the ceiling. For effective operation smoke
- alarms
should be located away from corners. Don't install a smoke alarm too near a
- window
or door. On a normal flat ceiling prerably install the smoke alarm near the
- centre,
but in any case a minimum of 150 mm from the nearest wall.
- In
rooms with high pitched ceilings, mount the alarm at or near the ceiling
high
- point.
-
- Practice your home fire drill with your children, so everyone
knows how to get out
- safely
if a smoke alarm activates. There are pamphlets available to help you with
- this.
-
- Fire Safety Officers are based at Christchurch Headquarters
station. There are currently 6 Fire Safety Officers plus a Regional
Technical Advisor.
- They cover the Canterbury
( North Canterbury & Christchurch) areas, and are able to provide
advice
on fire safety matters. They are available to present fire safety talks to
groups. Fire
Safety Officers provide advice and assistance to building owners and
managers to achieve
- They also assist in
determining the cause of a fire, when requested by fire officers.
