Text For Citation: 03 Item/Group: 001 Hazard:

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 August 17, 2018, and at times prior thereto, range worker(s) required to work in the handgun and rifle ranges were exposed to airborne concentrations of Lead above 50 microgram per cubic meter of air. This condition exposed employees to inhalation hazards during customer supervision and range cleaning operations: a) Range worker(s) were exposed to Lead at an 8-hour Time Weighted Average (TWA) up to 1.669 milligrams per cubic meter of air, which is over 33 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 455-minute period and the calculations include a zero value for the 25 minutes not sampled. b) Range worker(s) were exposed to Lead at an 8-hour TWA up to 1.151 milligrams per cubic meter of air, which is approximately 23 times the PEL of 50 micrograms per cubic meter of air. The exposure level is derived from a sample collected over a 413-minute period and the calculations include a zero value for the 67 minutes not sampled.
