Lab Safety Review

Flammable materials, like alcohol, should never be dispensed or used near

• an open door
• an open flame
• another student
• a sink

If a laboratory fire erupts, immediately

• notify your instructor
• run for the fire extinguisher
• throw water on the fire
• open windows

Approved eye protection devices (such as goggles) are worn in the laboratory

• to avoid eye strain
• to improve your vision
• only if you don’t have corrective lenses
• anytime time chemicals, heat, or glassware are used

If you wear contact lenses in the school laboratory

• take them out before starting the lab
• you do not have to wear protective goggles
• advise your science instructor that you wear contact lenses
• keep the information to yourself

If you do not understand a direction or part of a lab procedure, you should

• figure it out as you do the lab
• try several methods until something works
• ask the instructor before proceeding
• skip it and go to the next part

After completing an experiment, all chemical wastes should be

• left at your lab station for the next class
• disposed of according to your instructor’s directions.
• dumped in the sink.
• taken home.
