Text For Citation: 02 Item/Group: 003B Hazard:

29 CFR 1910.1025(e)(4)(i): When ventilation was used to control exposure to lead, measurements of the system's effectiveness were not conducted within five days of a change in production, process, or control which could result in a change in employee exposure. On or about August 17, 2018, and times prior thereto, the employer modified the ventilation system in the rifle range and did not take measurements of the ventilation system to ensure the control of airborne lead. These conditions exposed employees to inhalation hazards: a) Range worker(s) in the rifle range to supervise customers using fire arms and perform range cleanup 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) in the handgun range to supervise customers using fire arms and perform range cleanup were exposed to Lead at an 8-hour TWA up to 1.151 milligrams per cubic meter of air, which is over 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.
