Abstract	Exposure to bis(chloromethyl)ether (542881) was surveyed at Diamond Shamrock Chemical Company (SIC-2821) in Redwood City, California on February 16, 1972. The company employed about 100 workers directly involved in resin manufacturing. The only medical personnel at the facility was a local general surgeon. Pre-employment physicals were given and annual chest X-rays were voluntary. Management reports informed employees about the possibililty of lung cancer risk following bis(chloromethyl)ether exposure. The company provided safety glasses, shields, and shoes, paid half the cost of work clothes and paid for laundering. Four employees exposed to bis(chloromethyl)ether had died of lung cancer since 1964 and two employees were currently alive with lung cancer. Five of the six were smokers. The authors suggest that an excessive lung cancer risk exists. They recommend obtaining and examining death certificates and pathology reports for the six cases and a retrospective cohort study of the association between exposure and the risk of site-specific cancer. They also recommend annual sputum cytology, chest X-rays and discouragement of smoking for all exposed employees. Respirators should be worn by at risk employees and contaminanted clothing should not be taken home.
