Protect Your Eyes
• Appropriate eye protection must be worn at all times!
• Inform your teacher if you wear contact lenses.

Wear appropriate protective clothing
• Lab aprons can be used to protect good clothing and you
• Loose clothing should not be worn because it may dip into chemicals or fall into a flame and catch fire

Wear shoes that cover your feet.
• Sandals and open-toed shoes do not protect your feet from broken glass that is frequently found in the lab

Do not apply cosmetics, eat, or drink in the lab.
• These activities are ways by which you can accidentally ingest harmful chemicals

Check glassware for stars or cracks.

Handle hot glassware with gloves or beaker tongs.

First light the match
THEN
Turn on the gas!
![Page 16: Chemistry laboratory safety rules](https://reader035.fdocuments.us/reader035/viewer/2022081416/55cf109bbb61eb08368b460f/html5/thumbnails/16.jpg)
Do not smell any chemicals directly!
• Smell chemicals only if your teacher specifically tells you to do so, then use your hand to fan the vapor to your nose.

Do not pipet solutions by mouth!
• Use a rubber suction bulb or other device to fill a pipet.
![Page 18: Chemistry laboratory safety rules](https://reader035.fdocuments.us/reader035/viewer/2022081416/55cf109bbb61eb08368b460f/html5/thumbnails/18.jpg)
Wash your hands with soap and water before leaving.
• This rule applies even if you have been wearing gloves!

Know the hazards of the materials being used.
• Read and reread labels carefully to make sure that you are using the right chemical.
• Pay attention to the warnings about the chemicals used in the lab.

Tie Back Loose Hair
• Dangling hair can fall into the Bunsen burner and catch fire or can fall into a chemical solution
• P.S. Burning hair REALLY STINKS!

Carry out only the experiments assigned by your
teacher
I wonder what he’s
planning to do with that
thing.

Never work alone in the lab
• In case of a problem, you may need another person to prevent injury or even save your life!

Remember that the lab is a place for serious work!
Careless behavior may endanger yourself and others and will not be tolerated!
