||The effects of two kinds of masks (with or without exhaust valve) on clothing microclimates inside the mask in participants wearing protective clothing for spraying pesticides
||Jan. 2004, Vol.77, No.1, p.73-78. Illus. 16 ref.
||This study examined the effects of wearing two types of protective mask on the microclimate (temperature, humidity) inside the mask, physiological parameters and subjective sensations. Five healthy female students performed an intermittent step exercise while wearing the mask in a climate chamber at 28░C and 60% relative humidity. One mask was made of non-woven fabric and had no exhaust valve (mask A), and the other had an exhaust valve (mask B). Microclimate temperature, microclimate humidity and cheek skin temperature inside the mask were significantly lower in mask B than in mask A. Body temperature also increased more slowly with mask B. Mechanisms of heat loss are discussed.
