Background: Rigarding the occurrence of heat strain when using acid-resistant protective work clothing in the workplace, this study aimed to determine the performance of two types of cooling vests on heat strain indices in hot conditions when wearing acid-resistant protective clothing.Methods: This experimental study was conducted on ten healthy boy students in hot conditions of temperature of 40 °C and relative humidity (RH) of 25% when they wearied acid-resistant protective clothing. Each participant was contributed in three trials including without cooling vest (A), with ice gel cooling vest (B) , and phase change material paraffin (C). In each trial, participant walked on tread mill for 90 minutes. Heart rate, oral temperature, and skin temperature were measured in regular times.Findings: The mean of heart rate was 104.0, 97.2, and 97.7 beat/minute in A, B, and C trials, respectively. Moreover, skin temperature was 37.1 °C, 31.1 °C, and 33.2 °C, and oral temperature was 36.3 °C , 33.0 °C, and 34.0 °C in A, B, and C trials, respectively. There was significant difference in physiological heat strain indices between B and C trials with A trial.Conclusion: When using acid-resistant work clothing, wearing ice gel cooling vest and phase change material paraffin can reduce physiological heat strain indices.
