| Outline of Final Research Achievements |
Safety-assessment on the static electrical propensities of work clothes in Japan is carried out by electric charge level. In practical use, we consider that the hazard related to static electrical charge is dependent on human body voltage. We thought up two trial movements for determination of human body voltage: one is taking off movement after performing frictional action between work clothes and inner wear, the other is standing up from the seat of popular use chair quickly after performing frictional action between the back part of work clothes and the back of a chair. Experimental works were performed by using four types of unprotected commercial work clothes and six types of static protected commercial work clothes. Standing up movements from the seat of chair were recorded higher human body voltages than taking off movement. And, it was found that some work clothes including several static protected work clothes exceeded 5kV which occured spark discharge from human body.
