-
It is prudent to minimize all chemical exposures:
even for substances of no known significant hazard. Skin
contact should be avoided as a cardinal rule.
-
Avoid underestimating the risk of chemicals you
work with. One should assume that any mixture will be more
toxic than its most toxic component, and that all substances of
unknown toxicity are toxic.
-
Make sure there is adequate ventilation, and that
you are familiar with the proper use of equipment such as fume hoods
or biological cabinets.
-
Observe the rules of the Chemical Hygiene Plan in
the facility you are working in. CHESS's Chemical Hygiene Plan
is posted outside the Chem Room door.
-
Observe the Permissible Exposure Limits of OSHA
and the Threshold Limit Values of the American Conference of
Governmental Industrial Hygienists.
-
Wear appropriate personal protective equipment.
eg: Gloves, lab coats, safety glasses, and aprons.
-
Chemical containers must be labeled with the
identity of the product, the chemical constituents, and any
appropriate hazard warnings. Labels must not be removed or
defaced.
-
In the event of an accident or spill:
Eye contact: promptly flush
eyes with water for a prolonged period and seek medical attention.
Ingestion: encourage the
victim to drink large amounts of water.
Skin Contact: promptly flush
the affected area with water and remove any contaminated clothing.
If symptoms persist after washing, seek medical attention.
Clean-Up: promptly clean up
spills using appropriate protective apparel and equipment, and
proper disposal.
-
Do not eat, drink, smoke, apply cosmetics or
contact lenses, or use mouth suction for pipetting in the laboratory
at any time.
-
Restrict use of the lab while you are at work.
-
Before leaving the lab: clean up your work
area and be sure your chemicals are stored and labeled properly.
