Health hazard evaluation report: HETA-94-0329-2574, Standard Steel, Burnham, Pennsylvania.

In response to a request from current employees of Standard Steel (SIC-3296) located in Burnham, Pennsylvania, an investigation was begun into possible hazardous working conditions at that site. Workers were concerned about exposures to alumino-silicate fiber insulation which lined the interior of the industrial furnaces. A total of 16 time weighted average personal breathing zone and work area samples were collected and analyzed for total and respirable particulates. Respirable quartz (14808607) was detected in one refractory ceramic fiber (RCF) removal sample, below the minimum quantifiable concentration. No cristobalite was detected in any of the samples. The ten time weighted average area total particulate samples from Heat Treatment Plant Number One and RCF removal operations ranged from 0.10 to 0.52mg/m3. No quartz or cristobalite was detected in any of these samples. It was recommended that workers handling RCF should wear specific levels of respiratory protection and that company officials should monitor RCF concentrations regularly to characterize the task specific exposures to RCF. Such information will assist the company in determining the appropriate level of respiratory protection for specific tasks.
