Safety

When you are smelling a chemical, you should

• whiff

• waft

• take a deep breath

• smell it for as long as you can

It is OK to start a lab before you read all the directions.

• True

• False

Goggles are worn during science experiments--

• only if you don't have glasses

• to protect your eyes any time chemicals, heat or sediments are used

• to improve vision

• to avoid eye strain

You have been injured in the lab (cut, burned, etc.) First you should -

• apply first aid yourself

• tell the teacher at once

• see a doctor after school

• visit the school nurse after class

What should you do with chemicals leftover after an experiment?

• Follow the directions of the teacher

• Carefully pour them down the sink

• Throw them into the trash can

• Leave them on the table

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.

Long hair in the laboratory must be -

• cut short

• held away from the experiment with one hand

• always groomed neatly

• tied back or kept entirely out of the way with a hair band, etc.

When you finish working with chemicals, biological specimens, and other lab substances, always -

• treat your hands with skin lotion

• wash your hands thoroughly with soap and water

• wipe your hands on a towel

• wipe your hands on your clothes

When using a razor blade or scalpel, always cut material -

• away from you

• toward you

• in your hand

• perpendicular

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.
