PROTECTIVE GLOVES

Fire and Heat•Wear safety goggles

•Tie back long hair and secure loose clothing

•Do not heat FLAMMABLE liquids

•Use a heat source in a safe area

•Only the teacher uses the matches

•Hot plates do not look hot and be aware of the electrical cord attached to the hot plate

• Be careful of candle drippings- they can burn

• Learn about the fire extinguisher and fire blanket

• Only use glassware made for heating• Heated glassware does not look hot• Report broken glass to the teacher

Fire and Heatcontinued

Fire Extinguishers

The Science of FireFires need three things to start and to continue to burn:

•Fuel

•Oxygen

•Heat

These three items are part of the fire triangle. Removing or disrupting one of the points will prevent the fire from starting or

will extinguish the fire.
