Chemical Spills- If a student spills a chemical, stop what you are doing and ask a teacher for assistance. Do not clean up a spill by yourself. In most cases, if you spill chemicals on yourself it is best to run cool water over the area. This depends on the chemical being used. Ask your teacher for instruction if you spill chemicals on yourself.
