Environmental microbial assays of industrial @entity3178 were conducted following reports of multiple intershift @entity5517 . Pathogenic @entity794 was identified among the microorganisms cultured. This paper suggests that direct contact with industrial @entity3178 provides a potentially significant route of transmission of both @entity41825 . An industrial hygiene ocular health questionnaire was distributed to a first and second shift manufacturing operation to assess the incidence of @entity5517 . These data were compared to the questionnaire responses of 122 control manufacturing workers who did not use microscopes. Based on self-reporting by employees, those who used microscopes were found to have statistically significant incidence of sites and @entity2024 that was 8.3 times that of the control group. Sterilization of eyepieces by @entity11540 , @entity406 and @entity5723 were considered, but ultimately rejected. These biocides were found respectively to @entity16 , contribute to volatile organic emissions, or be ineffective against spore-forming bacteria. This article presents a detailed evaluation of a commercially available ultraviolet sanitization unit (manufactured by the King Bactostat Corp., 7115 Armistad Street, El Paso, TX 79912). This ultraviolet disinfection process proved to be rapid and emission free; it also yielded eyepieces free of residual chemical biocides that have the potential for ocular irritation. Field tests involving 60 eyepieces demonstrated effective disinfection by a Chi-Square statistical comparison, at values greater than 95% confidence level, as compared to unirradiated eyepieces.
