Lab Safety Symbols

You see symbols all around you. You knew the answers immediately what they meant. That’s because symbols convey (give) a lot of information in a split second.

Symbols are used in science labs, too. They are used to caution us against accidents and harm. These symbols need to be simple so that we can understand their meanings in a split second.

The following are safety symbols used in businesses around the world. What are the cautions that they convey? (Just share your ideas aloud for 2 minutes only. Use the

clock on your computer to time yourselves. These symbols will NOT be on your upcoming test; Ms. Tresten just wants you to see how easy it is to interpret good

safety symbols.)

Safety goggles: always wear safety goggles to protect your eyes in activities involving chemicals, flames, heating, or

with the possibility of broken glass

Lab apron - wear to protect your clothing and skin from damage

Breakage - you are materials that may be breakable. Handle with care.

Heat-resistant gloves - use oven mitt or other hand protection when handling hot

materials. Do not use bare hands.

Heating: use clamps or tongs to pick up hot glassware

Sharp object - you will be using sharp tools such as needles, scalpels, or

scissors. Sharp edge should be pointed away from yourself and others.

Electric shock - avoid the possibility of electric shock. Never use electrical equipment around water or with wet

Poison- do not ingest. Do not inhale. Wash hands

when done with activity

Physical safety - May involve physical activity. Take precautions to avoid injury.

Follow teacher instructions.

Fumes - poisonous or unpleasant vapors may be involved. Work in ventilated area. When asked to test an odor, use wafting

motion.

Flames - during lab, you may be working with flames from a candle, burner, or

match. Tie back loose hair and clothing.

No flames- flammable materials may be present. Make sure there are not flames or

sparks present.

Disposal - chemicals and other lab materials used in activity must be disposed of safely. Follow teacher

instructions.

Hand washing - wash hands thoroughly when finished with

activity.

General Safety Awareness - you may see this symbol when none

of the other symbols are present. Read and follow specific

instructions.

Corrosive chemical - you are working with an acid or another corrosive chemical. Do not inhale. Wash hands when done.

What does this symbol tell you?

If

We know if you drop something that is glass in class, the first thing you should

do is tell the teacher. What should you do if you get your lab supplies and notice a

beaker is chipped?

Tell the teacher!
