Health hazard evaluation report HETA 94-0273-2556, Bruce Mansfield Power Station, Shippingport, Pennsylvania

Technical Report ·
OSTI ID:285204
In response to a request from the Plumbers and Steamfitters Union Local 47, an investigation was begun into possible exposure to arsenic and other heavy metals during the rebuilding of coal fired boilers at the Bruce Mansfield Power Station (SIC-4911), Shippingport, Pennsylvania. Metal concentrations were measured in 45 personal breathing zone (PBZ) samples; an additional 12 PBZ samples were monitored for exposure to respirable dust and silica. Eight bulk ash samples and 11 hand wipe samples were taken. The workers put in 60 hour work weeks, 10 hours a day for 6 days. Arsenic was detected in 18 samples and ranged from 0.30 to 31 micrograms/cubic meter (microg/m3) with three of the samples exceeding the adjusted OSHA permissible exposure limit of 5.6microg/m3. In 11 samples, beryllium was detected, and ranged from 0.02 to 0.04microg/m3. Cadmium was detected in seven samples and ranged from 0.17 to 2.5microg/m3. Both the beryllium and cadmium concentrations were below the allowable limits. Lead concentrations were measurable in 12 samples and ranged from 1.7 to 1.82microg/m3, with one sample exceeding the OSHA limit of 28microg/m3. Crystalline silica was below the detectable limit.
