What to Do In The Event Of a Range Top Grease Fire
• SMOTHER FLAMES with a tight fitting lid, cookie sheet, or metal tray, and then turn off the burner.
KEEP FLAMMABLE OR COMBUSTIBLE MATERIALAWAY FROM FLAMES. If the flames do not go
out immediately, EVACUATE THE AREAAND CALLTHE FIRE DEPARTMENT or 911.
• NEVER PICK UP A BURNING PAN – You May Get Burned.
• DO NOT USE WATER, including wet dishcloths or towels – a steam blast will result.
• Use an extinguisher ONLY if:
a) You have a Class A, B, C extinguisher and know how to operate it.
b) The fire is small and contained in the area where it started.
c) The fire department has been called.
d) You can fight the fire with your back to an exit.
What to Do If You Smell Gas
- Extinguish any open flame.
- Do not try to turn on the lights or any type of appliance.
- Open all doors and windows to disperse the gas. If you still smell gas, call the Gas Company and
Fire Department right away.
CAUTION
1. For general ventilation use only. Do not use to exhaust hazardous or explosive materials and vapors.
2. To reduce the risk of fire, use only metal ductwork. Sufficient air is needed for proper combustion and
exhausting of gases through the flue (chimney) to prevent back drafting.
3. Follow the heating equipment manufacturer’s guideline and safety standards such as thosepublished
by the National Fire Protection Association (NFPA), and the American Society for Heating,
Refrigeration and Air Conditioning Engineers (ASHRAE), and code authorities.
