Smoke Alarms conform to regulatory

requirements, including UL217 and are designed to detect particles
of combustion. Smoke particles of varying number and size are
produced in all fires.

Ionization technology is generally more sensitive than photo-
electric technology at detecting small particles, which tend to be
produced in greater amounts by flaming fires, which consume

combustible materials rapidly and spread quickly. Sources of these
fires may include paper burning in a wastebasket, or a grease fire in
the kitchen.

Photoelectric technology is generally more sensitive than ionization
technology at detecting large particles, which tend to be produced
in greater amounts by smoldering fires, which may smolder for

hours before bursting into flame. Sources of these fires may include
cigarettes burning in couches or bedding.

For maximum protection, use both types of Smoke Alarms on
each level and in every bedroom of your home.

FIRE SAFETY TIPS

Follow safety rules and prevent hazardous situations: 1) Use smoking
materials properly. Never smoke in bed. 2) Keep matches or lighters
away from children; 3) Store flammable materials in proper containers;
4) Keep electrical appliances in good condition and don’t overload elec-
trical circuits; 5) Keep stoves, barbecue grills, fireplaces and chimneys
grease- and debris-free; 6) Never leave anything cooking on the stove
unattended; 7) Keep portable heaters and open flames, like candles,
away from flammable materials; 8) Don’t let rubbish accumulate.

Keep alarms clean, and test them weekly. Replace alarms immediately
if they are not working properly. Smoke Alarms that do not work cannot
alert you to a fire. Keep at least one working fire extinguisher on every
floor, and an additional one in the kitchen. Have fire escape ladders or
other reliable means of escape from an upper floor in case stairs are
blocked.
