Desiccant embedded PPE suit to keep PPE dry and bearable
My idea is to embed PPE with desiccant packs to absorb the sweat. Desiccant readily absorbs liquid from air and can be worn underneath PPE to absorb a large amount of liquid depending upon the type of desiccant used. Given that the environment is not at too high of a temperature to risk the user of getting hyperthermia, a desiccant PPE suit should greatly extend the time the user can wear it.
One of the problems of wearing PPE besides it being very hot to wear is the humidity. As the user gets warmer they will sweat more. Complaints arise from goggles fogging up and to having a shortage of socks because they are drenched in sweat and give a maximum of 45 minute wear time between changes. http://www.npr.org/2014/10/07/354230895/ebola-protective-suits-are-in-short-supply
Desiccant to absorb sweat in PPE
The thought is that a 90 degree dry heat can be tolerable where as a 90 degree humid day is very uncomfortable. If the desiccant can keep PPE dry, this will extend the time the careworker can wear the suit.
Some desiccants are readily available and quite cheap. Packs of these can be stored inside PPE during use then when user takes it off the desiccant can be recharged of its adsorption ability by heating off the adsorbed sweat --say over a fire ... or the packs can be thrown away and new packs be used.
Some possible dessicants could include zeolite, silica gel, or calcium chloride.
