Fall 2010
Proper Lab Attire
Safety glasses must be worn at all timesNo contact lenses – can retain and

Discard all broken, chipped, starred or badly scratched glassware
Do not attempt to catch glassware if dropped or knocked over
Do not pressurize conventional glassware
Fume Hoods
Serve as a physical and chemical barrier for chemical exposure
Keep head outside of hood Keep sash closed if not in use Keep sash opening at a minimum
when in use Keep clutter inside hood to a
minimum Don’t use for chemical storage
Preparation of Solutions
Always add concentrated chemical (e.g. acid or base) to water – NOT water to concentrated chemical

Waste containers have to be labeled with date and contents
Keep waste segregated by type: organic vs. inorganic, etc.
