Health hazard evaluation report: HETA-98-0030-2697, Pratt and Whitney TAPC, North Haven, Connecticut.
On November 24, 1997, the National Institute for Occupational Safety and Health received a union request for a health hazard evaluation (HHE) at the Pratt and Whitney Aircraft TAPC (P&W) facility in North Haven, Connecticut. The HHE request concerned reports of health problems possibly associated with exposure to metal working fluids (MWFs) in the Blohm grinding area. The reported health problems included flu-like symptoms, skin problems, and eye irritation. On March 31-April 2, 1998, 12 bulk samples of MWF were collected for microbiological and endotoxin analysis, and personal breathing zone (PZB) and area air sampling for MWFs was conducted on both the first and second shift in the Blohm grinding area. PBZ samples were also collected from employees in a comparison area (Business Unit 264), where MWFs are not used. Area air samples for endotoxin analysis were collected in both the Blohm grind and comparison area on both shifts. A questionnaire that included questions about symptoms potentially related to MWF exposure was administered to employees in the Blohm and comparison area on all three shifts.
