lab safety

What should you do if you break glass in the lab?

• Tell the teacher.
• Sweep up the glass.
• Pick up the glass with your hands.
• Ignore it; the teacher will clean it up when she sees it later.

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

When should safety goggles be worn?

• at all times in the lab
• when you feel like it
• when liquids could splash into your eyes OR when using glassware

When in the lab...

• long sleeves and loose clothing should be rolled up
• closed toe shoes should be worn
• long hair should be pulled back
• all of the above

When working in the lab, you always...

• work with only members of your group with a business-like attitude
• ask questions when in doubt about procedures
• clean up after yourself 
• all of the above

Before leaving the lab you should always wash or sanitize your hands.

• True 
• False

It's fine to do random experiments with the lab equipment without teacher permission.

• Ummmm... no!
• Sure- it'd be fine!

Flammable materials, like alcohol, should never be dispensed near

• an open door

• an open flame

• another student

• a sink
