Classroom Safety If you cut yourself, see the instructor, we need to know. No eating in the lab area unless instructed to do so. If you break it, you pay for it and you clean it up Eye Wash: irritants that need removing from your eyes Chemical shower: For spills of irritating chemicals on one’s body..emergency only… never been used since I have been here. Fire extinguisher: If you know how to use one, and you feel like you can handle the situation, use it; if not leave the room and shut door behind you. Fire blanket: for smothering fires and warming possible shock victims

Classroom cont. Respect : People, places and things---- Mutual If you used it, put it back….leave it better than you found it. Accidents will happen, Negligence is not tolerable. Do not fool around
