Laboratory
Standard
Laboratory use of
hazardous chemicals
 Chemical
manipulations are
carried out on a laboratory
scale
 Multiple
chemical procedures or
chemicals are used
1a
Laboratory use of
hazardous chemicals
 Procedures
are not part of, and
do not simulate a production
process
 Protective
laboratory practices
and equipment are available to
minimize employee exposure
1b
Permissible exposure
limits cannot be exceeded
 PEL
is the level a person can be
regularly exposed to without
adverse effects
• Eight-hour time-weighted average
• Ceiling concentration limits
• Skin designation limits
2a
Permissible exposure
limits cannot be exceeded
 Action
level is an exposure level
OSHA has designated for a
specific substance
• Eight-hour time-weighted average
• Exposures at action level initiate
exposure monitoring, medical
surveillance
2b
Exposure monitoring
 Measured
when there is reason
to believe exposure levels
exceed action level or PEL
 Performed
for substances
regulated by an OSHA standard
that requires monitoring
3a
Exposure monitoring
 Monitoring
may be terminated in
accordance with regulation
 Employees
must be notified of
monitoring results within 15
working days
• Individually
• Posting results in accessible
location
