Safety in the Science Classroom (Elementary) Mr. Wells Science 2012

Safety in the Science Classroom Eye and Personal Protection Fire and Heat Handling Chemicals Safety with Plants Safety with Animals Disposing and Clean-Up Emergency Procedures

Eye and Personal Protection Wear safety goggles when working with Chemicals Flying objects Fire/flame/hot objects and liquids Cutting glass Gases under pressure

Eye and Personal Protection continued Wear a lab apron and protective gloves when working with Animals and plants Chemicals Learn about the eyewash and safety shower

Eyewash and Safety Shower

Safety Goggles, Lab Apron and 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

Fire and Heat continued 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 Extinguishers

Fires need three things to start and to continue to burn: The Science of Fire Fires 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. Oxygen Fire Triangle Fuel Heat

Fire Blanket

Precautions BUNSEN BURNER HEATING TEST TUBES CANDLE HOT PLATE
