Students are never permitted in the science storage rooms or preparation areas unless given specific permission by their instructor. |
Know what to do if there is a fire drill during a laboratory period; containers must be closed, gas valve turned off, fume hoods turned off, and any electrical equipment turned off. |
Any time chemicals, heat or glassware are used, students will wear laboratory googles. There will be no exceptions to this rule! |
Contact lenses should not be worn in the laboratory unless you have permission from your instructor. |

Never leave a lit burner unattended. Never leave anything that is being heated or is visibly reacting unattended. Always turn the burner or hot plate off when not in use. |
Heated metals and glass remain very hot for a long time. They should be set aside to cool and picked up with caution. Use tongs or heat-protective gloves if necessary. |
Do not place hot apparatus directly on the laboratory desk. Always use an insulating pad. Allow plenty of time for hot apparatus to cool before touching it. |
