Chemistry Lab Safety

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

• Always
• During group work, but not during lab activities
• Never
• During lab activities

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

• Tell the teacher, sweep up the glass, and put it in the broken glass container
• Tell the teacher, sweep up the glass, and dump it into the garbage
• Pick up the glass with your hands
• Ignore it; the teacher will clean it up

Why should you clean all materials after working in the lab?

• Chemical residue left on the materials may affect later experiments or cause a chemical reaction
• Dirty classware may start to smell bad
• Some chemicals we use in labs may slowly dissolve glass, and if you leave them long enough holes will actually form
• Trick question - you actually don't need to wash your materials after lab as long as you remember to do it before lab next time. 

Keeping your work area neat and clean is important because:

• My teacher is a neat-freak
• I won't lose my supplies in the clutter.
• It keeps the room from looking messy.
• It helps prevent accidents.

I can perform my own experiments with lab materials ___.

• I am sure it is safe to do so.
• Whenever I want to.
• When all of my group is ready.
• Never.
