There was a fear of being sued that we hadn’t anticipated” “At the same time, we discovered


that the users themselves weren’t always prepared to “stop” when the system told them to. Guys in EOD suits have trialed these systems and said, ‘if I am looking at something beeping on my wrist telling me I am too hot and should leave, I am still going finish the job I need to do.’ The problem arises when the user has ignored the threshold indicators and doesn’t realise that due to heat strain and de- hydration, their cognition levels might already be impaired. These systems are


designed to prevent poor decisions in critical moments as well as simply to keep the wearer safe.” “The harsh reality is that if you put


on any form of CBRN PPE and do some heavy work you will get hot, uncomfortable and sweat a lot. Ironically, the fitter you are, the more you are likely to sweat.
