Why would you wear goggles in the lab?

• to prevent eye strain

• to improve your vision

• for protection from UV rays

• for protection from chemicals, heat, or glassware

If you do not understand a direction or part of a lab procedure, you should

• figure it out as you do the lab

• try several methods until something works

• ask the instructor before proceeding

• skip it and go on to the next part

After completing an experiment, all chemical wastes should be

• left at your lab station for the next class

• disposed of according to your instructor's directions

• dumped in the sink

• taken home

The first thing you should do if you get injured in the lab is

• tell the instructor immediately

• apply first aid yourself

When gathering glassware and equipment for an experiment, you should

• use a beaker to drink water

• carry as much as you can at one time

• stack the glassware to carry it

• examine all glassware to check for chips and cracks

Personal eyeglasses provide as much protection in a lab as
