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
• Wear a lab apron and protective gloves when working with– Animals and plants– Chemicals
• Learn about the eyewash and safety shower
Eye and Personal Protectioncontinued
Eyewash and Safety Shower
EYEWASH SAFETY SHOWER
Safety Goggles, Lab Apron and Protective Gloves
SAFETY GOGGLES
LAB APRON
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.
