| Popis: | Background and Aims: Existence of heat in industries is considered as a serious problem. Someindexes have been invited to evaluate the rate of heat loud on worker. These indexes have beenused & comprised in different researches. This research validity of some of these indexes wasevaluated.Method: In purpose of evaluation of indexes and environmental factor ordinary and CataTermometer, WBCT Meter instrument and Humidity Meter was used. As a first step Molding unitdivided into 15 stations, and in the second step parameters measurement was begone . After thatthe obtained figures was used in special equation to calculate heat stress indexes.Mouth, skin, and core body temperature of 90 healthy and adopted male worker was recorded.Then the obtained result was analysed by Spss, and mean, standard deviation and correlationcoficient was ealeutated for each of them.Results: At first mean, minimum, maximum and standard deviation was calculated forenvironmental parameter and indexes.At the second step the relationship between personalfactors (mouth, skin and core body temperature) and parameters and environmental indexes. (Airtemperature, radiation temperature, air velocity and relative humidity) was assessed.The result showed no significance relationship between personal factor and heat stressor. Factor(p>5% ) only purse index had significance relationship (p=0/005), and the others indexes did notshowed significance relationship.Conclusion: In this research the relationship between purse and all variables was significance.Therefore this index considered as a first valid index in this research.WBGTindex shows the most relationship after the purse index in comparison with other indexes.Because of the other indexes's no significance relationship, so pours had a good validity in thisresearch. |
