Abstract
In response to a request from the United Auto Workers Local 2323, an investigation was begun into potential worker exposures to N- nitrosamines at MBL-USA (SIC-3052), Ottawa, Illinois. Concern had also be expressed regarding potential exposures to crystalline silica (14808607) and asbestos (1332214). MBL-USA manufactured a wide variety of belts for both original equipment and service parts in the industrial and automotive markets. Approximately 210 workers were employed on site at the time of this study. Personal breathing zone and general area air samples were collected. Levels of nitrosodiethylamine (55185) (NDEA) in the Ring and Press Curing areas ranged up to 0.55 micrograms per cubic meter. A personal breathing zone air sample collected on the powder applicator contained 0.13mg/m3 respirable particulates, well below the OSHA permissible exposure limit of 5mg/m3. The bulk powder used to coat the belts was not found to contain asbestos or crystalline silica. The author concludes that no health hazards were documented. The author recommends that improvements be made in the effectiveness of the canopy hood ventilation systems in the Cure Press area, and that the personal protective equipment used in the Banbury area be improved.
