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

During lab activities you should always wear

• Goggles
• An apron
• Goggles and an apron
• Just normal clothing

When should you use the shower in the back corner of the lab?

• After P.E.
• After spilling chemicals onto your body
• Before going out on a date
• Never

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

• Tell the teacher, sweep up the glass, and put it where the teacher directs you
• 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

How should you carry heavy lab equipment?

• With one hand
• With two hands
• With four hands (use a partner)
• You shouldn't; the teacher carries all lab equipment

You should tie back long hair or baggy clothing

• When working with chemicals
• When working with a Bunsen burner
• When doing dissections
• Any time you are working in the lab

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. 

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

You come into the classroom and smell gas.  You discover one of the gas lines was left open by the previous class.  You should

• Ignore it
• Light the burner because you will need it for lab today
• Evacuate the room immediately
• Shut off the gas and tell the teacher

Your lab partner spills a test tube of something (you're not quite sure what) onto a Bunsen burner and it catches fire on your lab table.  You should

• Quickly fill a beaker with water and dump it onto the fire to put it out
• Tell the teacher and use the fire extinguisher
• Take a selfie with the fire in the background
• Try to blow out the fire since it isn't very big.
