WASTE MANAGEMENT AND SAFETY
, continued
•
Laboratory coats or splash aprons to protect skin and clothing
from splashes.
•
Footwear to protect feet from spills. Open toed shoes should not be
worn in chemistry settings.
•
Respirators may be needed to protect you from breathing toxic vapors
if adequate ventilation, such as fume hoods, are not available.
•
Use fume hoods as directed by the procedure or as recommended in
the MSDS.
•
For many procedures, adequate ventilation is enough. Be sure there is
enough fresh air and air exhaust to protect against unnecessary
exposure to chemicals.
First Aid Equipment and Supplies
Most first aid instructions for chemical splashes in eyes or on skin call for
thorough flushing with water. Laboratories should have eyewash and
shower stations. For field work, carry a portable eyewash unit.
Laboratories should also have appropriate fire extinguishers and fume
hoods.
General Safety Rules
Follow these rules to make work with toxic and hazardous
chemicals safer:
1. Never pipet by mouth. Always use a mechanical pipet or pipet bulb to
avoid ingesting chemicals.
2. Follow test procedures carefully and observe all precautionary
measures. Read the entire procedure carefully before beginning.
3. Wipe up all spills promptly. Get proper training and have the right
response equipment to clean up spills. See your safety director for
more information.
4. Do not smoke, eat, or drink in an area where toxic or irritating
chemicals are used.
5. Use reagents and equipment only as directed in the test procedure.
6. Do not use damaged labware and broken equipment.
7. Minimize all chemical exposures. Do not breathe vapors or let
chemicals touch your skin. Wash your hands after using chemicals.
8. Keep work areas neat and clean .
