A NIOSH walk-through industrial hygiene survey was conducted to identify a group of male workers exposed to butyl-glycidyl-ether (BGE). The survey was conducted to determine eligibility for a study of the effects of the chemical on reproductive histories. Because the workers were rotated, the operators were exposed to other toxic substances. Therefore, NIOSH concludes that any adverse effect found on male reproductive histories cannot be attributed conclusively to butyl-glycidyl-ether exposure. It recommends that rotated workers not be included in the study.
