Abstract
A health hazard evaluation of possible exposure to crystalline silica (7631869) and activated carbon (7440440) particulate at the Amstar Corporation (SIC-2062), Philadelphia, Pennsylvania was made. Amstar refines raw sugar into granulated sugar for eventual wholesale and retail sales. In the course of the operation some employees are required to open and dump 50 pound bags of diatomaceous silica and activated carbon into 2,000 gallon tanks. Environmental samples were collected to determine airborne levels of total and respirable crystalline silica and activated carbon particulate. Bulk samples were collected of Diatomite (diatomaceous silica and Darco (activated carbon). Employee interviews and observation of work practices were conducted. It was concluded that a health hazard due to employee exposures to free silica and total particulate did not exist.
