An industrial hygiene survey of fluidized bed combustion technology was conducted. The purpose of the survey was to characterize current or potential occupational health problems of fluidized bed combustion processes (SIC-4961). Air sampling was conducted for 18 chemical agents at three facilities utilizing fluidized bed boilers. Noise and ionizing radiation exposures were also evaluated. Mutagenicity evaluations were conducted on extracts of particulates and bulk samples. Exposure control technology was investigated. All air contaminant concentrations were below their OSHA standards. Mutagenic activity was found in high volume and bulk particulate samples at two facilities. The activity could be correlated with the air concentrations of coal-tar-pitch (8007452) volatiles. Noise levels exceeded 90 A-weighted decibels (dBA), the OSHA standard, at two facilities. No potential radiation hazards were found. Engineering controls included noise control enclosures to minimize exposure to noise from pressure blowers, forced draft fans at two sites and general room ventilation at all sites. The authors conclude that only a limited potential for exposure to airborne contaminants exists at the facilities. Recommendations include providing a hearing conservation program for employees exposed to noise levels of 185dBA or higher and implementing medical surveillance and employee safety and health training programs.
