29 CFR 1910.1025(c)(1): Employee(s) were exposed to lead at concentrations greater than fifty micrograms per cubic meter of air averaged over an eight-hour period: On or about February 1, 2019, and at times prior thereto and times thereafter, warehouse worker(s) required to remove the metal covering from the wire and mechanically separate the lead from the copper core of the wire were exposed to airborne concentrations of lead above 50 micrograms per cubic meter of air. This condition exposed employees to inhalation hazards: a) Warehouse worker(s) were exposed to lead at an 8-hour Time Weighted Average (TWA) up to 0.8178 milligrams per cubic meter of air, which is 16.4 times the Permissible Exposure Limit (PEL) of 50 micrograms per cubic meter of air. The exposure level is derived from a sample collected over a 390-minute period and the calculations include a zero value for the 90 minutes not sampled. b) Warehouse worker(s) were exposed to lead at an 8-hour Time Weighted Average (TWA) up to 0.3222 milligrams per cubic meter of air, which is 6.4 times the Permissible Exposure Limit (PEL) of 50 micrograms per cubic meter of air. The exposure level is derived from a sample collected over a 377-minute period and the calculations include a zero value for the 103 minutes not sampled. c) Warehouse worker(s) were exposed to lead at an 8-hour Time Weighted Average (TWA) up to 0.2212 milligrams per cubic meter of air, which is 4.4 times the Permissible Exposure Limit (PEL) of 50 micrograms per cubic meter of air. The exposure level is derived from a sample collected over a 387-minute period and the calculations include a zero value for the 93 minutes not sampled. d) Warehouse worker(s) were exposed to lead at an 8-hour Time Weighted Average (TWA) up to 0.8904 milligrams per cubic meter of air, which is 17.8 times the Permissible Exposure Limit (PEL) of 50 micrograms per cubic meter of air. The exposure level is derived from a sample collected over a 390-minute period and the calculations include a zero value for the 90 minutes not sampled. e) Warehouse worker(s) were exposed to lead at an 8-hour Time Weighted Average (TWA) up to 0.5268 milligrams per cubic meter of air, which is 10.5 times the Permissible Exposure Limit (PEL) of 50 micrograms per cubic meter of air. The exposure level is derived from a sample collected over a 372-minute period and the calculations include a zero value for the 108 minutes not sampled. f) Warehouse worker(s) were exposed to lead at an 8-hour Time Weighted Average (TWA) up to 1.0269 milligrams per cubic meter of air, which is 20.5 times the Permissible Exposure Limit (PEL) of 50 micrograms per cubic meter of air. The exposure level is derived from a sample collected over a 365-minute period and the calculations include a zero value for the 115 minutes not sampled. g) Warehouse worker(s) were exposed to lead at an 8-hour Time Weighted Average (TWA) up to 0.2313 milligrams per cubic meter of air, which is 4.6 times the Permissible Exposure Limit (PEL) of 50 micrograms per cubic meter of air. The exposure level is derived from a sample collected over a 367-minute period and the calculations include a zero value for the 113 minutes not sampled. h) Warehouse worker(s) were exposed to lead at an 8-hour Time Weighted Average (TWA) up to 0.6829 milligrams per cubic meter of air, which is 13.7 times the Permissible Exposure Limit (PEL) of 50 micrograms per cubic meter of air. The exposure level is derived from a sample collected over a 370-minute period and the calculations include a zero value for the 110 minutes not sampled. i) Warehouse worker(s) were exposed to lead at an 8-hour Time Weighted Average (TWA) up to 0.4087 milligrams per cubic meter of air, which is 8.2 times the Permissible Exposure Limit (PEL) of 50 micrograms per cubic meter of air. The exposure level is derived from a sample collected over a 338-minute period and the calculations include a zero value for the 142 minutes not sampled.
