In response to a request from the University of Utah Health Sciences Center (SIC-8062), Salt Lake City, Utah, a study was made of possible hazardous exposures to smoke generated by medical lasers during laser surgery and animal research procedures. Environmental sampling was conducted to determine occupational exposures to several airborne compounds and a health complaint questionnaire was administered to medical personnel. Detectable levels of ethanol (64175), isopropanol (67630), anthracene (120127), formaldehyde (50000), cyanide, and airborne mutagenic substances were recorded. Ethanol and isopropanol were detected at 4.7 parts per million (ppm) and 0.5 to 16.4ppm, respectively, below the OSHA and ACGIH evaluation criteria. Two short term samples of formaldehyde registered 0.21ppm and 0.44ppm, which could cause irritation in sensitive individuals. Airborne particle extracts were found to be mutagenic in the Ames test. Hydrogen-cyanide (74908) was detected at the laser irradiation site at a concentration of 100ppm. The authors conclude that exposure to constituents of smoke generated during laser surgery were a potential health hazard. The authors recommend the use of smoke evacuators to reduce exposures during laser procedures.
