Abstract
  • Animal researchers and pathologists who perform necropsies on animals may be exposed to significant concentrations of formaldehyde vapor. Because of complaints of respiratory and eye irritation, nausea, headaches, and recent animal data that suggests formaldehyde may be a carcinogen, several types of hoods have been used to control the process. A partial enclosure hood designed to control this process was evaluated using a tracer gas, sulfur hexafluoride, to determine the minimal operating conditions necessary to control vapors emitted within the hood under working conditions. Recommendations are made for improving the work practices of the researchers.
