Eye and Personal Protection

•Wear safety goggles when working with

•Chemicals

•Flying objects

•Fire/flame/hot objects and liquids

•Cutting glass

•Gases under pressure

• Wear a lab apron and protective gloves when working with– Animals and plants– Chemicals

• Learn about the eyewash and safety shower

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.
