Lab Safety Procedures
Always follow the instructions given by the teacher.
Read all of the directions before starting a lab.
You should be on your best behavior during a lab— horseplay is not tolerated and can be dangerous.
All accidents must be reported to the teacher.
Be sure to know the location and use of all safety equipment.
Always carry sharp objects with the sharp end pointed down.
Always cut away from yourself when using a scalpel or other sharp objects.
Do not eat or drink during a lab— never taste substances without the teacher’s permission.
Check all of your lab equipment before starting— report any damaged items to the teacher.
Clothing & Equipment
Tie back long hair and secure all baggy clothing (roll up sleeves, take off sweater, etc.) to reduce the risk of accidents— wear a lab apron/coat if needed.
Wear proper shoes— closed shoes are the best!
Always wear protective goggles when instructed by the teacher or while working with heat, chemicals, or sharp objects.
Chemicals & Substances
Always waft when instructed to smell a substance— never directly smell anything.
All chemicals and substances should be returned and left in the room at the end of the lab.
Always add acid last when mixing acid and other substances.
Use the eyewash station or safety shower for chemical splashes in the eye or skin.
Heat Sources
Never leave a heat source unattended— hot plate, Bunsen burner, lit candle, etc.
When heating a test tube, always point the end away from yourself and others.
Do not place hot glassware into cold water— it will shatter.
Lab Station
Always keep a neat and clean lab area— a cluttered area can increase the risk of accidents.
Dispose of trash in the correct container— most solids can go in a trash can and most liquids can be washed down the sink.
Never place unused chemicals back into their original container— this can cause contamination.
Clean all lab equipment and wash your hands at the end of a lab.
