Playing Safety Symbol Bingo
• In the following slides, you will see a safety symbol that is
represents an element of laboratory safety.
• Guess the symbol as a class and then record the picture on
your bingo sheet.
• Place a bean or item provided to you.
Please do NOT mark on the bingo sheets!
• You only really need to know what the symbol means, the rest is
common sense. (You can download all these slides from my
webpage if you want to know all the information later.)
• If You have Bingo, please wait until the end and we’ll check it.
• We’ll keep going until we go through all 10 lab safety symbols.
• Afterwards, we’ll recap by examining photographs and
determining what laboratory safety rules are being broken!
• Get ready and good luck!
What am I?
Safety Goggles
• Used for Eye protection.
• The most common used
safety item in the biology
laboratory.
• Use when there are
Chemicals, Flames or
Heating.
• They give you protection
against flying objects or toxic
substances.
• If your eyes come into
contact with a substance, use
the eye wash immediately.
What am I?
Poison
• Do not let it on your skin or
inhale its vapor.
• Wash your hands after
handling.
• Can cause death if eaten or
drunk.
• Let your teacher know
immediately if you come into
direct contact.
• Always hold test tubes or
flasks away from your nose
and face and waft odors
towards you.
What am I?

cleaned with each use
to avoid
contamination.

handling hot materials.
Use clamps or tongs to hold
hot objects.
Always heat objects in a test
tube away from you and
others.
Hot plates, hot water and hot
glassware can cause burns.
Glassware looks the same
when hot or cold, so use care
when heating any type of glass.
Rapid changes in glass
temperature can cause it to
expand, crack and/or explode!
Plastic tools should never be
heated on a hot plate!
– They will melt!
• Never touch hot objects with
your bare hands.

other corrosive
chemical.

• Be careful when
dissecting preserved
animals.

Now it’s your turn!
• Determine the following reasons these people are
violating laboratory safety rules.
• Try to use terms you have already learned
through the 10 basic safety symbols.
• Check your Bingo sheet;
does anyone have Bingo?

Reflect:
As a class, let’s review some
of the safety violations that
we can see.
What were some things you
saw at the beginning?
What are some things you
see now after learning about
lab safety?
Any Questions about
Lab Safety and
Safety Procedures?
Now let’s play a Game…
• In efforts to get to know another and make good
observations/inferences, I’m going to give your lab bench a
phrase.
• The first person reads the phrase I wrote and draws a
picture of how they would communicate it to the next
person.
– They fold down the phrase and pass it down.
• The next person looks at the picture and writes a
description of what is happening.
– They fold down the picture and pass it down.
• Continue in this pattern until you reach the end of the row.
– We’ll share our results! And NO PEEKING!
