Fire Prevention and Escape
The purpose of an early warning smoke detector is to detect the presence of fire in its early stages and sound an alarm giving the
occupants time to exit the premises safely.
Avoid Fire Hazards
No detection device can protect life in all situations. Therefore, safeguards should be taken to avoid potentially dangerous situations as
follows:
• Do not smoke in bed.
• Do not leave children home alone.
• Never clean with flammable liquids such as gasoline.
• Properly store materials. Use general good housekeeping techniques to keep your home neat and tidy. A
cluttered basement, attic, or other storage area is an open invitation to fire.
• Use combustible materials and electrical appliances carefully and only for their intended uses. Do not overload
electrical outlets.
• Do not store explosive and/or fast burning materials in your home.
• Even after proper precautions have been taken, fires can start. Be prepared.
