“…Small changes to the thermal insulation properties of a water vapour permeable EN 469:2005-type [1] protective clothing have only minimal, if any, effect on heat exchange and do not affect the resulting thermal strain [7]. However, even a microporous water barrier liner may expose a fire fighter to more pronounced heat and cardiovascular strain during prolonged rescue operations as compared to protective clothing without a barrier [8,9].…”

“…Consequently, individuals may be unable to maintain a thermal steady state during high intensity exercise ≥4 8 km h -1 and 5% elevation), regardless of the garment type worn . In contrast, when performing low intensity exercise ≤4 5 km h -1 and 0% elevation) the rate of heat production increase is lower than during high intensity exercise,, therefore resulting in a greater opportunity for clothing changes to effect heat loss (Holmér et al 2006;). The addition of protective clothing to low intensity exercise increases heat production, however in this wear protocol it did not increase to the extent of high intensity exercise, as seen by the lower T re response reported in this study.…”

“…When wearing protective clothing instructors' work load increases, resulting in an increase in heat production and requirement for heat loss (Rossi 2003;Dreger et al 2006;Holmér et al 2006). However, the clothing also reduces evaporative heat loss capacity and therefore when combined with high temperatures, an uncompensable heat stress situation occurs, resulting in heat storage (Havenith 1999;Cheung, McLellan, and Tenaglia 2000).…”

Fire service instructor's undergarment choice to reduce Interleukin-6 and minimise physiological and perceptual strain

Fire Service Instructors frequently experience high levels of physiological and perceptual strain during live fire exposures. Instructors are also at risk of cardiovascular illnesses, with cardiac death being the greatest cause of fire fighter death. Current practice for UK instructors is to select undergarment type based on personal preference, between a boiler suit (BOILER) and a wicking base layer (WBL). Research suggests that shorts and t-shirt (SHORTS) may also be a beneficial alternative undergarment choice. The UK South East Fire Service requested an investigation to identify if undergarment selection can lessen the strain experienced by instructors, and reduce the acute inflammatory response to fire exposures. Eight males completed three 45 min sessions in a heat chamber (49.5 ± 1.4°C and 16.9 ± 4.3% RH) whilst performing intermittent walking. At the end of heat exposure change in heart rate was not effected by garment type (p=0.061, p 2 =0.373). Change in rectal temperature was different between garments (p=0.009,  p 2 = 0.271), with trends suggestingthat BOILER resulted in a greater change (1.03 ± 0.60°C) than SHORTS (0.76 ± 0.37°C, p=0.589, d=0.21) and WBL (0.72 ± 0.33°C, p=0.545, d=0.25). Interleukin-6 post exposure was greater for BOILER (6.96 ± 0.28 pg.mL -1 ) than both SHORTS (6.59 ± 0.30 pg.mL p=0.043, p=0.031, d=0.51). Overall, undergarment type had little impact on physiological or perceptual strain. However, wearing WBL or SHORTS may reduce the inflammatory response, and consequently decrease the risk of cardiovascular events.

A firefighting simulation was developed in order to assess the physical work capacity of firefighters. The simulation consisted of eight common firefighting tasks, including walking with radiant heat for 3 min while wearing full personal protective equipment (PPE). Nine professional firefighters performed the test a total of three times with a 5 min rest interval between each session. The entire series of tests took approximately 30 min to complete (381 ± 30 s). Rectal temperatures were found to increase from 37.4 ± 0.3 o C to 38.5 ± 0.4 o C, while heart rates were found to increase from 92 ± 18 bpm to 185 ± 13 bpm during testing. Time to completion of the test drills and non-modified physical fitness values showed a significantly negative correlation (r = −0.728, p < 0.05). Firefighters who had longer periods of firefighting service had longer duration time and also recorded higher scores using an integrated scoring system of time to completion (TTC) and physiological strain index (PhSI). The results indicated that the determination of TTC alone can be a misrepresentation of capability, as it neglects to account for accumulated heat strain. The simulated firefighting test provided a useful insight into physical fitness level, but also the comprehensive work capacity of the firefighters when assessed based on TTC and PhSI.
