Fire and Fire Drills In case of a fire alarm, do the following: Close ALL containers. Turn off ALL gas valves. Unplug All electrical devices.

Dispose of all chemical waste properly, according to instructions; Clean equipment and work area after use; Return all materials to proper location

Keep hands away from face, eyes and mouth while using chemicals Wash hands thoroughly before leaving lab

Goggles and aprons must be worn at all times during a lab No contact lenses! Wrong! Correct

Chemical Burn of the Eye A chemical burn of the eye can be prevented by WEARING GOGGLES.

Reporting Accidents Report ALL accidents, injuries, fires, and chemical spills to the teacher immediately. Report me.
