The National Institute for Occupational Safety and Health (NIOSH) received a request to conduct a health hazard evaluation (HHE) from a coroner's office. Specifically, the request was for NIOSH assistance in evaluating a pneumatic reciprocating saw, equipped with local exhaust ventilation (LEV), used for cranial openings during forensic autopsies and examinations. The pneumatic saw was being evaluated by the coroner's office as an alternative to the electrically driven reciprocating saw. The objective of the NIOSH evaluation was to determine if the reciprocating saw 1) generated less tissue and bone fragment aerosol that could potentially challenge the breathing zone of the operating forensic technician, and 2) reduced the noise exposure to the technician and surrounding personnel. The NIOSH investigation included real-time area and personal measurement of airborne particulates, and real-time spectral measurement of noise during the conduct of six autopsies (four autopsies for the noise evaluation). The investigation was conducted in cooperation with the County Health Department, who simultaneously collected particulate air samples for microscopic analysis of bone and tissue fragments.
