Lead Exposure
Reference: B-4
If workers are exposed to lead for more than 8 hours in a workday, their allowable exposure as a TWA for that
day must be reduced according to the formula below.
Worker exposure (in μg/m3) = 400 divided by the hours worked in the day
Action Level (AL), regardless of respirator use, is an airborne concentration of 30μg/m3, averaged over an 8hour period. The AL is the level at which an employer must begin specific compliance activities outlined in the
standard.
EXPOSURE ASSESSMENT
The Company shall determine if any worker may be exposed to lead at or above the Action Level (AL). Worker
exposure is that exposure which would occur if the worker were not using a respirator.
Where monitoring is required, The Company shall collect personal samples representative of a full shift including
at least one sample for each job classification in each work area either for each shift or for the shift with the
highest exposure level. Full shift personal samples shall be representative of the monitored worker's regular,
daily exposure to lead
PROTECTION OF WORKERS DURING ASSESSMENT OF EXPOSURE
When The Company performs a worker exposure assessment and documents that the worker performing any
of the listed tasks is not exposed above the PEL, The Company shall treat the worker as if the worker were
exposed above the PEL, and not more than ten (10) times the PEL and shall implement worker protective
measures. The tasks covered by this requirement are for certain tasks prone to produce high lead exposure.
These include:
•
•
•
•
•
•

•
Manual demolition of structures such as dry wall, manual scraping, manual sanding, and use of a
heat gun where lead containing coatings or paints are present

Abrasive blasting, rivet busting, welding, cutting, or torch burning on any structure where leadcontaining coatings or paint are present
