WARNING CAUTION

• Not intended for cooking with more than 1” oil depth before food is added.

• Not recommended for gas stoves; powder may extinguish burner ﬂame on a gas stove top

• If safe, turn burner OFF immediately after activation.

• Reignition is possible.

• When suppressing powder comes in contact with ﬁre, it may brieﬂy ﬂare and/or cause grease to splash. This is a normal and temporary reaction.

• This product may not suppress all stove top ﬁres.

FIRE SAFETY

• Unattended cooking is the leading cause of ﬁres in the kitchen. Many injuries occur when occupants attempt to ﬁght the ﬁre themselves.

• Never leave anything cooking on the stove top unattended! If you have to leave the kitchen —even for a short time— turn off the stove.

• Never leave home or fall asleep while you are cooking.

• Never pick up a ﬂaming pan. You may be burned, or if the pan is dropped, ﬂames may quickly spread to other ﬂammable areas.

• Never use water to ﬁght a grease ﬁre! A violent explosion may result. Wet dishcloths or towels are also dangerous.

• Always follow National Fire Protection Association (NFPA) guidelines for proper cooking safety. Visit www.nfpa.org.
