Health hazard evaluation report: HETA-92-0174-2363, Commercial Steel Treating Company, Cleveland, Ohio.
NIOSH 1993 Oct; :1-16
In response to a request received from the Sentinel Event Notification System for Occupational Risk Program (SENSOR) from the Ohio Department of Health, a study was conducted on exposures to respirable silica (14808607) at a sandblasting operation being conducted at the Commercial Steel Treating Company (SIC-3471) in Cleveland, Ohio. SENSOR had been informed of the death of a sandblasting worker due to silico tuberculosis; the worker had been employed at the company for 10 years. The facility heat treated and sandblasted products such as weldments. Air samples obtained from the sandblasting area were evaluated for airborne respirable silica and medical evaluations, including chest X-rays, were conducted on 16 of the 17 employees. All but one of the air samples demonstrated levels of respirable quartz that were in excess of the OSHA permissible exposure limit of 0.1mg/m3. Abnormal pulmonary function test results were seen in five of the workers. Four had opacities in the lungs of 1/0 or greater, one had advanced silicosis, and four had radiological evidence of tuberculosis scarring. The author concludes that there is a serious problem related to respirable silica dust at this sandblasting operation. The author recommends that medical screenings and engineering controls be instituted.
