Lead Exposure
Reference: B-4
Training regarding Hazard Communication, use of respirators, and safety training and education
BASIS OF INITIAL DETERMINATION
The Company shall monitor worker exposures and shall base initial determinations on the
worker exposure monitoring results and any of the following, relevant considerations:
•
•
•
Any information, observations, or calculations which would indicate worker exposure to lead
Any previous measurements of airborne lead
Any worker complaints of symptoms which may be attributable to exposure to lead
AIR MONITORING
Initial Determination
The Company has made an initial determination of lead work areas and exposure levels and will conduct
subsequent "initial determinations" in the event of changes to hazard control methods or operational processes
that affect worker or environmental exposure. Initial determinations are conducted to determine if any worker
may be exposed to lead at or above the action level of 30 micrograms per cubic meter of air (30 ug/m (3)) but
below the permissible exposure limit (PEL) of 50 μg/m3.
Where a determination is made that no worker is exposed to airborne concentrations of lead at or above the
action level, the company shall maintain a written record. The record shall include quantitative sampling data,
date of determination, location within the worksite, and the name and social security number of each worker
monitored.
Air Monitoring Requirements
Monitoring and analysis methods shall have an accuracy (to a confidence level of 95%) of not less than plus or
minus 20 percent for airborne concentrations of lead equal to or greater than 30 ug/m (3).
Where a determination shows the possibility of any worker exposure at or above the action level, the company
shall conduct monitoring which is representative of the exposure for each worker in the workplace or process
area who is exposed to lead.
For the purposes of monitoring requirements, worker exposure is that exposure which would occur if the worker
were not using a respirator.
Monitoring and sample collection shall cover full shift (for at least 7 continuous hours) personal samples
including at least one sample for each shift for each job classification in each work area.
