1.2.9
Lead Permissible Exposure Limit (PEL)
Fifty micrograms per cubic meter of air as an 8 hour time weighted average
as determined by 29 CFR 1926.62. If an employee is exposed for more than
eight hours in a work day, the PEL shall be determined by the following
formula:
PEL (micrograms/cubic meter of air) = 400/No. hrs worked per day
1.2.10
Material Containing Lead/Paint with Lead (MCL/PWL)
Any material, including paint, which contains lead as determined by the
testing laboratory using a valid test method. The requirements of this
section does not apply if no detectable levels of lead are found using a
quantitative method for analyzing paint or MCL using laboratory instruments
with specified limits of detection (usually 0.01%). An X-Ray Fluorescence
(XRF) instrument is not considered a valid test method.
1.2.11
Personal Sampling
Sampling of airborne lead concentrations within the breathing zone of an
employee to determine the 8 hour time weighted average concentration in
accordance with 29 CFR 1926.62. Samples shall be representative of the
employees' work tasks. Breathing zone shall be considered an area within a
hemisphere, forward of the shoulders, with a radius of 150 to 225 mm 6 to 9
inches and centered at the nose or mouth of an employee.
