HHE determination report no. HHE-75-196-290, Bruce W. Weatherwax, D.D.S., Torrington, Wyoming.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 75-196-290, 1976 May; :1-5
A health hazard evaluation of the room air samples for inorganic mercury (7439976) conducted in the Bruce W. Weatherwax Dental Clinic (SIC-8021) in Torrington, Wyoming, shows that the concentrations of mercury during the evaluation are below the NIOSH detection limit of per cubic meter. A health hazard is not judged to exist at the time of evaluation. Recommendations include use of tightly closed capsules during amalgamation, salvaging all amalgam scraps and storing in a closed container with a layer of water over the amalgam; storing of mercury in an unbreakable, tightly sealed container; and, cleaning up of all mercury spills immediately, preferably by vacuuming. Sweeping has to be avoided because it creates dust and breaks the mercury into even smaller particles that can vaporize more quickly.
