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, March 21, 2019, employees working in the following operations located in the foundry were exposed to lead at concentrations greater than fifty micrograms per cubic meter of air over and eight-hour period: a) A foundry oven helper providing assistance to various foundry jobs was exposed to lead at an 8-hour Time Weighted Average (TWA) of 62.42 micrograms per cubic meter of air during the 450 minute sampling period. This is 1.248 times the permissible exposure limit of 50.0 micrograms per cubic meter. Exposure calculations include a zero exposure increment for the 30 minutes not sampled. b) A skimmer that skims lead containing molten metal from slag pots was exposed to lead at an 8-Hour Time Weighted Average of 65.78 micrograms per cubic meter of air during the 434 minute sampling period. This is 1.32 times the permissible exposure limit of 50.0 micrograms per cubic meter. Exposure calculations include a zero exposure increment for the 46 minutes not sampled. c) A casting line operator was exposed to lead at an 8-Hour Time Weighted Average of 83.60 micrograms per cubic meter of air during the 423 minute sampling period. This is 1.67 times the permissible exposure limit of 50.0 micrograms per cubic meter. Exposure calculations include a zero exposure increment for the 57 minutes not sampled.
