Laboratory Safety Guidelines
2
Prepare Properly

• Wear a lab apron when working with harmful
  chemicals.
• Wear safety goggles when working with chemicals
  or heating substances.

3
Adult Supervision

• Never conduct experiments without adult
  supervision.
• If you are injured notify the teacher immediately.

4
Special Equipment

• Be familiar with the location of the following
  equipment
• A. Fire extinguisher
• B. Fire blanket
• C. Emergency shower
• D. Eye-wash station

5
Spills

  where someone can trip over them!
• When working with electricity make sure your
  hands are dry.

10
Clean Up

• Be sure that all laboratory surfaces, equipment,
  and tools are cleaned after you finish with them
• Dispose properly of all chemicals.

11
Heat!

• Turn off hot plates and burners when not in use.
• Turn off microscopes when not in use.

12
Heating Substances

• When heating a substance, always point the test
  tube away from you and other people.
• When heating over a burner (flame), gently move
  the test tube over the hottest part of the flame.
• Use tongs or hot pads when handling hot
  equipment. Use a test tube holder when heating
  substances in a test tube.

  circumstances. It can lead to chemical spills,
  accidental fires, and broken equipment.
• Never throw anything.
• No wrestling, punching or shoving in the lab even
  if youre just playing.
• Those types of behaviors will result in your

  yesterday?
• On a sheet of paper (NOT your notebook) answer
  these questions
• 1. How can you use these rules outside of class?
  
• 2. Give me some examples of rules from science
  class that are similar to rules that you follow
  at home
