Chemistry Laboratory Safety Quiz

1. You should pipette by mouth.

A Always. It's a fast and efficient method of measuring liquids.

B Only when you can't find a pipette bulb or think it might be dirty.

C Only when you are sure your instructor, lab assistant, or co-worker isn't looking.

D Never. And if you thought about answering yes to any other the other choices should be slapped.

2. When you are finished using a Bunsen burner you should:

A Leave it on for the next person to use. It's the only considerate choice.

B Cover the burner with an inverted beaker to suffocate the flame. It works well for candles, too.

C Pull off the hose connecting the burner to the gas. The burner won't have gas, so it won't be on fire.

D Turn off the gas. Duh!

3. If you feel dizzy or sick while working near the fume hood you should:

A Head out to grab a cola or a snack. Maybe it's low blood sugar. Don't tell anyone – why bother them.

B Meh, no big deal. Do nothing. Fume hoods always protect you from harmful chemicals. The sooner you get finished the sooner you can leave.

C Report your symptoms to whoever is responsible for that fume hood. It might be nothing, but on the other hand, maybe the hood wasn't functioning properly and you were exposed to something. Look up the MSDS for whatever was in the hood, too. Leave the lab, after contacting the proper person.

4. If you catch on fire you should:

A Panic. Yelling FIRE at the top of your lungs to let others know about the danger is good. Be sure to run as quickly as possible to blow out the flame.

B Water fixes everything. Head for the nearest safety shower and drown the flame.

C Pull the fire alarm and look for help. Hope the fire doesn't burn you too badly before you can take some form of action.

D Smother the flame. Those blankets in the lab are there for a reason. Some fire doesn't really care about water, but all flames need oxygen. Get help, too. You weren't working alone in the lab though, right?

5. Your glassware is clean enough to eat, therefore you poured water into a beaker to quench your thirst. Too bad you didn't label it. You should:

A Go on with your business. Are you saying there is some safety issue here? I scoff at you!

B Just be really careful about keeping it separate from other beakers filled with clear liquid. Hydrochloric acid.. water.. there is a difference, but I can smell the acid before I drink it.

C Label it before you forget which beaker it is. You're sure there are no residual chemicals in the glassware and positive nothing could accidentally splash into your drink.

D Look back to an earlier answer about how you should be slapped for stupidity. Food and drinks don't belong in the lab.

6. You really want to impress a certain person in your lab. You should:

A Be sure to wear contacts, not glasses, and just be really careful about chemical fumes. Got long hair? Don't tie it back, flaunt it. Nice legs? Wear something short, with sandals to show off those toes. Also, impress him or her by doing something daring in the lab. Choose something involving fire.

B Ditch the lab coat and goggles. Dress to impress. There's no way the person can tell your fashion sense when you cover it with safety gear.

C Hey.. lab coats are cool! Only ditch the goggles.

D Impress him or her with how incredibly competent you are in the lab. That includes your ability to follow safe lab procedures.
