In response to a request from the Assistant Administrator of the Cranston General Hospital (SIC-8062), Cranston, Rhode Island, an investigation was made of possible hazardous working conditions due to exposure to nitrous-oxide (10024972). The hospital has three active operating rooms with as many as nine employees potentially exposed to the gas at any one time. Operating room personnel complained of headaches and tiredness. The company supplying the anesthetic equipment conducted an on site evaluation of the equipment and indicated leaks were detected at the absorber. A recommendation was made that all rubber hose connections be changed. Air quality measurements were then taken by the hospital insurance company and found to be in excess of the NIOSH recommended limit of 25 parts per million (ppm). Corrective action was then taken by the management of the hospital. Five area samples collected subsequently by NIOSH during three different surgical procedures indicated nitrous-oxide levels of less than or equal to 10ppm. The author concludes that a health hazard did not exist from exposure to waste anesthetic gases. The author recommends that the hospital's existing program for controlling exposure to waste anesthetic gas and vapor be strengthened.
