TI  - Validity of infrared tympanic temperature for the evaluation of heat strain while 
      wearing impermeable protective clothing in hot environments.
PG  - 714-25
AB  - The purpose of this study was to investigate the validity of infrared tympanic 
      temperature (IR T(ty)) as a thermal index to evaluate the heat strain of workers 
      in hot environments, in comparison with rectal temperatures at various depths 
      (T(re-4, -8, and -16) for 4, 8 and 16 cm from the anal sphincter). Eight males 
      underwent twelve experimental conditions: two activities (rest and exercise) x 
      three clothing levels [Control, HDPE (high-density polyethylene coverall) and PVC 
      (polyvinyl chloride coverall) condition] x two air temperatures (25 and 32℃ with 
      50%RH). The results showed that 1) in the conditions with most heat strain (HDPE 
      or PVC condition at 32℃), IR T(ty) was equal to or even higher than T(re); 2) 
      during exercise, physiological strain index (PSI) using IR T(ty) did not 
      underestimate PSI-values using T(re-16), and overestimated those PSI-values from 
      T(re-16) in HDPE and PVC conditions at 32℃; 3) during exercise, the relationships 
      between IR T(ty) and heart and total sweat rate were stronger than those between 
      T(re-16) and heart and total sweat rate. These results indicated that IR T(ty) is 
      valid as a thermal index to evaluate the heat strain of workers wearing 
      impermeable protective coveralls in hot environments. However, the application of 
      IR T(ty) is limited only for strenuous works wearing encapsulated personal 
      protective clothing with a hood in heat.
