In response to a request from management at the New Hampshire Ball Bearing, Astro Division (SIC-3562) located in Laconia, New Hampshire, an investigation was begun into possible hazardous working conditions at that site. Approximately 450 people worked at the facility, eight of whom worked in the Composites Department, which was the area being evaluated. Five bulk dust samples were obtained from locations in the Composites Department. Sampling indicated that the employees in the Composites Department were exposed to very low concentrations of total airborne fibers. Fiber dimensions exceeded the limit of respirability, and did not present an inhalation hazard. Transient skin itch reported by some workers was associated with the handling of carbon fiber reinforcement material prior to impregnation. The investigators suggest that composite dust generated by mechanical processes such as cutting and sanding, may contribute to itching as a result of dust coming in contact with exposed skin. It was recommended that gloves and protective clothing be used and selected based on the permeation and degradation resistance to materials used by the workers, that once resin gets on the skin the workers should immediately remove it using soap and water, that protective coveralls and sleeve protectors be used, that local exhaust ventilation systems be reevaluated, that good housekeeping practices be emphasized, and that all machinery be guarded effectively.
