||Active versus passive cooling during work in warm environments while wearing firefighting protective clothing

||This study examined whether active or passive cooling during intermittent work reduced the heat strain associated with wearing firefighting protective clothing (FPC) and self-contained breathing apparatus (SCBA) in the heat (35░C, 50% relative humidity). Fifteen male Toronto firefighters participated in the study. Subjects walked at 4.5km/h with 0% elevation on an intermittent work (50min) and rest (30min) schedule. Work continued until rectal temperature reached 39.5░C or heart rate (HR) reached 95% of maximum or exhaustion. One of three cooling strategies, forearm submersion in water, mister, and passive cooling were employed during the rest phases. Findings suggest that there is a definite advantage when utilizing forearm submersion compared with other methods of active or passive cooling while wearing FPC and SCBA in the heat.
