7.0 PERSONNEL EXPOSURE AND AIR QUALITY MONITORING
7.1 AIR QUALITY (DUST)
Due to the nature of the principal contaminants associated with
the project, dust suppression will be
important as a means of minimizing exposure levels and off-site
migration of contaminants. The
Field Team Leader will routinely monitor the project area. The
OSHA personal exposure limit
(PEL) for nuisance dust is 15 mg/m3.
7.2 AIRBORNE CHEMICAL MONITORING
Monitoring for airborne chemical exposure is as important as other
occupational safety precautions.
Monitoring for airborne chemical contaminants exposure
requires the following elements:
• Air sampling for particulates and specified CoPCs,
• Recordkeeping regarding personnel work locations and time in
location, and
• Respiratory protective equipment records for devices used by
workers in airborne
contaminant areas.
By closely monitoring these three elements, a continuous
record of personnel exposure to airborne
chemical contaminants is maintained.
General methodologies for sample collection and analysis include,
7.2.1 PERSONAL AIR MONITORING
Each Subcontractor and trade employer shall evaluate the
need to=perform personnel air
sampling for the contaminants during Abatement Phase of the
project.
The results of personnel monitoring conducted will be
reviewed on a daily basis by the
Subcontractor Safety Officer to determine if current levels of respiratory
adequate. protection are
The subcontractor safety officer shall provide written
documentation of this review to the
CSO and the subcontractor must immediately report any results
that trigger PPE upgrades.
Additional evaluation of samples shall be performed when determined
necessary based
upon elevated results.
