[Methodic approaches to evaluation of microclimate at workplace, with application of various types of protective clothing against occupational hazards].

Studies of heat state of human involved into physical work in heating environment and having various protective clothing on demonstrated value of the protective clothing in modifying thermal load on the body and possible decrease of this load through air temperature and humidity correction, shorter stay at workplace. The authors presented hygienic requirements to air temperatures range in accordance with allowable body heating degree, suggested mathematic model to forecast integral parameter of human functional state in accordance with type of protective clothing applied. The article also covers necessity of upper air temperature limit during hot season, for applying protective clothing made of materials with low air permeability and hydraulic conductivity.
