Lab Safety in Chemistry

When is it OK to eat or drink at the lab stations?

• Always

• Right after the lab is done.

• Never

• During lab activities

Part of lab safety includes reading the lab procedure...

• before doing the lab
• while doing the lab
• after doing the lab
• only if you think you really need it

You notice a beaker half full of a leftover powdered chemical and you are pretty sure you know which chemical it is.  You should

• Ask the teacher what to do with the chemical
• Pour the chemical back into the container you think it came from
• Pour the chemical into the garbage can
• Pour the chemical down the drain with the water running

Horseplay, jokes, and pranks are appropriate in the lab at any time.

• True
• False

When working in the lab it is the expectation that...

• you work with only members of your group with a business like attitude
• you ask questions when in doubt about procedures
• you clean up before lab if needed and as you are doing lab 
• all of the choices are correct

What is the main safety when you are carrying lab equipment/chemicals around the room?

• Walk slowly and with care

• Make a run for it and hope it doesn't break

• Crawl with it on your back.

• Run and trip with it.

What is the proper way of smelling chemicals?

• waft it or fan it to your nose

• go nose deep and start smelling!

• smell directly

• stick your finger in the chemical and smell your finger after

You have been injured in the laboratory (cut, burn, etc.). First you should

• apply first aid yourself
• tell the teacher right away

• see a doctor after school
• visit the school nurse after class

You are heating a piece of glass and now want to pick it up. You should 

• pour cold water on it
• use tongs
• pick up the end that looks cooler
• use a rag or paper towels

 After completing an experiment, all chemical wastes should be

• taken home
• dumped in the sink
• disposed of according to teacher's directions

• left at your lab station for the next class
