Science Blog: Intro to safety symbols found in labs

Personal Safety:

Wear goggles and an apron anytime you are working with dangerous chemicals, hot liquids or solids, and other potential sources of splashes, splattering or spills.
Goggles must be worn anytime a Bunsen burner is used.
Make use of any safety equipment such as beaker tongs, test tube clamps, thermal gloves, etc. when handling hot beakers, test tubes or other containers.
Do not wear a coat or jacket during a lab. Necklaces and bulky jewelry should be removed. These items tend to get in the way when reaching for objects and can get caught in moving parts such as motors.
Do not perform any experiment that is unauthorized.
Study your lab assignment/experiment before you come to class. If you have any questions, ask the instructor for help.

A bunsen burner flame is very hot. The center of the flame will be over 1000 degrees Celsius. Treat burner flames with respect.
Always use the main gas shut off valve on the desk to shut off a bunsen burner. The valve at the base of the burner is only used to control the flame.
If your hair or clothing catches on fire stop drop and roll.
If someone else's hair or clothing catches on fire, wrap them with a fire blanket to smother the fire. Do not let them run, running will feed more oxygen to the fire.
