    Default Cooling Vests

    I am interested in information on firefighter cooling vests to be worn under turn outs. I have found many manufacturers but have not been able to find many Fire Depts that have used them.

    Our bomb squad uses them, but we opted against them for the haz mat unit. The biggest problem is that on a really hot day, you may outlast the cooling effect. Then you end up with a bag of hot water on your back. Not good.

    Bullard sells a rechargable cooling vest called the Isotherm. For more details, you can go to http://www.bullard.com/products/Resp...e/isotherm.cfm

    NEIDNER also makes one that according to their specifications will last about 2 hours and can be recharged in 30-45 seconds with an umbilical...

    I know our county haz mat team used them at one point. They may still, but I'm not sure.

    For interior fire ops though, has anyone ever heard of one of these things breaking? If there is some kind of liquid inside that is used to keep the wearer cool, does it vaporize quickly?

    I guess I would be worried that a ruptured vest could create a situation where the wearer would be Steam Burned in a high heat environment?

    Does anyone know if this is even a risk to worry about?

    The Bullard Isotherm vest has a gel on the inside. I believe it is slightly caustic, making it a mild skin irritant, but it is not hazardous or flammable.

    The packs are pretty tough to break...I haven't worn one under gear, but I've played with them elsewhere and they take a beating. They are marketed for use during rehab, though, even if you get one a with Nomex shell.
