Aim: To investigate the impact of structural firefighting on firefighter hydration. Design: Prospective Cohort Study. Methods: Three separate studies, following similar structural firefighting tasks, were conducted over three years. Participants (2014 n=7, 2016 n= 7, 2017 n=22), who were qualified firefighters, conducted a 15-minute series of tasks associated with fire suppression in a specifically adapted training container whilst dressed in standard authorised PPE (mean weight 21.39±0.68 kg), and a 6.8 L Self Contained Breathing Apparatus (9.6 kg full and 8.6 kg empty). The temperatures imparted by the fire ranged from 40-51 degrees at 0.3 m above floor to 458-572 degrees at ceiling height. Measures included tympanic (2014, 2016, 2017), skin (2014) and core body temperature (2017), body weight (2014, 2016, 2017) and urine specific gravity (2014, 2016, 2017). Results: On multiple occasions firefighters commenced duties in a state of dehydration. Skin temperatures while wearing personal protective equipment were significantly higher than ambient temperatures. Significant increases in tympanic and core body temperatures (p<.001), and decreases in body weight (p<.01) were found following suppression tasks. There were no significant changes in urin specific gravity. Conclusion: Firefighters experienced notable thermal stress when conducting fire suppression tasks wearing personal protective equipment.
