In response to a request from the City of Harrisburg, Pennsylvania, a health hazard evaluation was conducted at the Harrisburg Steam Generation Facility (HSGF) (SIC-4953) concerning possible exposure to fly ash, combustion products and asbestos (1332214). This facility was a waste to energy site where municipal refuse was incinerated at approximately 1400 degrees-F. The steam generated was either sold directly or converted to electricity via an on site turbine. Employees used hard hats, safety shoes and glasses, work clothes and single use disposable dust and mist respirators. There was a potential for exposure to fly ash for employees working in the boiler and basement areas. Total particulate exposures ranged from 5 to 11mg/m3 for laborers. The concentration of lead (7439921) exceeded the standards set by OSHA permissible exposure level of Amosite (12172735) and chrysotile (12001295) asbestos were identified in bulk samples of insulation and asbestos taken from a settled dust sample in the boiler area. Surface wipe samples indicated the possibility of hand to mouth contact with fly ash, particularly in the break and locker rooms. The author concludes that there is a need for reducing worker exposure to fly ash particulate. The author recommends engineering and work practice controls to reduce particulate exposures, increased cleaning and maintenance activities; and further evaluation of asbestos contamination at the facility.
