Environmental sampling and medical evaluations were conducted at HI- G Company, Inc. (SIC-3724), Windsor Locks, Connecticut, on October 2 and 3, 1978, and March 26 and 27, 1979 to determine the cause of numerous outbreaks of illness. A company representative requested the evaluation on behalf of an unspecified number of employees. Personal and area samples for airborne organotin , lead (7439921), trichlorotrifluoroethane (26523648) (Freon TF), and 1,1,1- trichloroethane (71556) were collected. Exposures to phosgene (75445), hydrogen-cyanide (74908), hydrogen-chloride (7647010), carbon-monoxide (630080), carbon-dioxide (124389), and formaldehyde (50000) were also evaluated. Bulk samples of solders, fluxes, and cleaning agents were analyzed for thermal by-products. The medical evaluation included medical record reviews and personal interviews. None of the substances in the air samples exceeded recommended standards. NIOSH investigators concluded that an environmental health hazard did not exist from any of the chemicals evaluated. They note that after the initial outbreak of illness in 1976, employees might have been more aware of various environmental conditions, and that subsequent minor environmental changes may have precipitated outbreaks of illness. Recommendations include: the continuance of high quality medical recordkeeping; maintenance and relocation of exhaust ventilation systems; and capping of floor drains when they are not in use.
