Abstract
Environmental samples were collected to determine airborne concentrations of waste anesthetic gas nitrous-oxide (10024972) and mercury (7439976) at a dentist's office (SIC-8021) in Albany, New York on June 13 to 15, 1979. The dentist requested the evaluation on behalf of the 5 affected employees. Nitrous concentrations in personal and area samples were 10 to 30 parts per million (ppm) and 10 to 135ppm, respectively. No OSHA standard for nitrous oxide currently exists. Direct reading measurements of mercury vapors revealed concentrations of up to 0.15 milligrams per cubic meter (mg/cu m) on office surfaces; however personal samples of mercury concentrations were within OSHA limits of 0.1mg/cu m, time weighed average and ceiling limit. The authors recommend that ventilation and maintenance improvements be made, chemical substances be isolated, and procedures for toxic waste disposal be formalized. When improvements have been implemented, a follow up evaluation should be made.
