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 labâ 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 labâ never taste substances without the teacherâs permission.
Check all of your lab equipment before startingâ 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 accidentsâ wear a lab apron/coat if needed.
Wear proper shoesâ 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 substanceâ 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 unattendedâ 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 waterâ it will shatter.
Lab Station
Always keep a neat and clean lab areaâ a cluttered area can increase the risk of accidents.
Dispose of trash in the correct containerâ 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 containerâ this can cause contamination.
Clean all lab equipment and wash your hands at the end of a lab.
