HHE Report No. HETA-90-348-2135, Grosse Pointes-Clinton Refuse Disposal Authority, Mount Clemens, Michigan.
NIOSH 1991 Sep:23 pages
In response to a request from a representative of employees at the Grosse Pointes-Clinton Municipal Refuse Authority (SIC-4953), Mount Clemens, Michigan, an evaluation was undertaken of possible exposures associated with incinerator ash at the incinerator site. Two visits to the site were made. During the first visit it was determined that the weekly clean out operation was the primary source of employee exposures to ash. During the second visit analyses were made of air samples, total dust, respirable dust, respirable crystalline silica (14808607), ash and metals. Potential short term exposures to high levels of crystalline silica, lead (7439921), and total dust were noted during the clean out operation. One personal air sample collected for total dust exposure measured 20.5mg/m3 which exceeded the OSHA Permissible Exposure Limit (PEL) of 15mg/m3. The NIOSH Recommended Exposure Limit of 0.5mg/m3 for crystalline silica was exceeded for one personal breathing zone air sample. The author concludes that workers were exposed to crystalline silica, lead and total dust during cleanout; personal exposures did not exceed the OSHA PELs because cleanout was completed in less than 2 hours. The author recommends improvements to work practices and provision of better personal protective equipment.
