Abstract
Personal air samples from breathing zones and area samples were analyzed and leak tests were conducted over accessible portions of the analgesia system at a dental office (SIC-8021) in Milford, Ohio, on September 4, 1980, to evaluate the effectiveness of a scavenging system for use during administrations of nitrous-oxide (10024972) (N2O). The dentist was exposed to time weighted average N2O concentrations ranging from 23 to 250 parts per million. The dentists' assistant was exposed to N2O concentrations ranging from 16 to 30ppm. Area air samples ranged from 3 to 36ppm. Investigations before the installation of a scavenging scheme had indicated that all personnel were exposed to N2O concentrations ranging from 180 to 1,000ppm, while area sample concentrations of N2O ranged from 180 to 525 ppm. The NIOSH recommended environmental criteria for N2O exposure is 50ppm. The author concludes that the scavenging system reduced N2O exposures in the dental office. He recommends that the analgesia system be made leakproof and the proper amount of suction be applied to the scavenging system.
