[Occupational safety and health at small scale enterprises co-operating with a medical university]

This descriptive study reports the results of a systematic survey on occupational safety and health hazards and risks to exposed workers at companies co-operating with a medical university, and investigates the effective methods for their management. Varieties of works at all these co-operating companies have been categorized into 14 types of businesses. The survey was performed in two-fold; an individual interview of managers and a comprehensive inspection of workshops, and a questionnaire to all workers (response rate 95.9%). All of the co-operating companies were small-scale enterprises with less than 50 employees. The occupational safety and health risks to be controlled were accidental contact with biomedical wastes, heat in the kitchen, laundry and boiler room, unfavorable ventilation at workplace close to medical facility, and physical fatigue of guards and janitors. A higher number of occupational health physicians and a higher rate of health examinations were observed compared to other small-scale enterprises in Japan. About 80% of all workers were conscious of working on the premises of medical facilities. To improve the occupational safety and health activities of co-operating companies, we propose the use of professionals at the medical university, the promotion of joint activities among the co-operating companies, and the strengthening of mutual connection and coordination between the co-operating companies and the medical university.
