Having health care workers pass out from heat stress is obviously no good for anyone. We monitor heat stress using an older Equivital system. It uses core temp pills and can also pick up heart rate (two key indicators of heat stress). The beauty o
NASA has used liquid air based life support equipment to support the space program for many years. We deal with hot (think Florida in summer) dangerous (think highly toxic fuels) environments on a regular basis. Vaporization of liquid air, to provi
I don't really have any links. Most of the technology is trapped in the US space industry. It is all based on liquid air. It is dense, low pressure, requires heat to vaporize, dry, and free of any bugs. All of these factors make it ideal for use in hot hazardous environments. We have been doing it for years in the space industry. There have been a variety of factors that have kept it from going commercial, but we have resolved most of those issues. To the point that the National Institute of Occupational Safety and Health has funded us to develop life support solutions for mines. The liquid air can be put in a backpack, or vaporized externally to a suit and then fed through a hoseline. Anyway probably not the answer you were looking for?
All, just to let you know, since this is a NASA centered idea, NASA KSC has used Cryogenic Life Support in highly protective suits for a long time. It solves both problems of heat and protection. We are working with USAid, & OSTP to toss out some potential ideas. At this point, the biggest obstacles we face are cost and logistics. Just to let you know that NASA is in the game and trying to lend what support we can.
