Laboratory Safety

Question 4 • 2001340-Environmental Science Sem 1 - Pearson

Which of the following actions would you take to remain safe in the lab?Check all of the boxes that apply.

Answer
A
A bottle of liquid looks like water; you taste it to be sure.
B
While cutting a screen for an aquarium top, you point the scissors away from your body.
C
You pipette a liquid using a bulb pipette.
D
You heat a liquid by placing it in a plastic beaker on a hot plate.
E
You arrange all lab items neatly and make sure they are away from the edge of the lab table.

Explanation

Pointing scissors away from your body helps prevent injury if they slip. Use a bulb pipette to draw up liquid; never pipette by mouth. Keeping lab items neat and away from the table’s edge helps prevent spills and falling objects. Do not taste an unknown liquid, and do not heat liquid in a plastic beaker on a hot plate.
