This study was carried out to clarify the microclimate and physiological effect of protective clothing. Four protective clothings (Protective Coveralls for Asbest abatement work, Chemical Protective Clothing, Protective Clothing for Agricultural Chemicals and Thermal insulative Clothing) were tested.Results obtained were as follows. 1. At the asbest abatement work in 25-27ﾟC,physiological strains were not so severe,but at the work in 2-3ﾟc higher environment,heart- rate counted 140-170 beat/min and rectal temperature rose about 40ﾟc. There was a high risk of suffering from heat illness. 2. From the results of wearing tests in climate room,microclimate of protective clothing became hot and humid, so it was very uncomfortable condition. 3. To improve the microclimate of protective clothing,the structure of fabrics, he textile properties and motional function of protective clothing were studied. From the view point of improvement of motional efficiency, protective clothing were necessary more amount of ease of length direction. 4. From a result of wearing test of protective clothing for agricultural chemicals, use of hood type blower showed good physiological responses. 5. An apparatus for a fabric evaluation of chemical protective clothing,especially acid protective clothing was designed.This apparatus was useful for screening of fabrics for chemical protective clothing.
