Does anyone have experience with fr cool vests? We are a Texas utility considering fr cool vests trial during high temperature situations. Any thoughts, pros, cons, compliance issues, etc...??

Thanks,
Nathan

Haven't come across an arc rated version of this. Have seen them in Coal Fired Power Plants, not sure if they were FR for Operators not electrician use for energized electrical work arc flash protection.

Where would you use them in an MCC Building or process area will electrical equipment is located and ambient termperature is high?

FR cooling vests exist for both Flash Fire and Electric Arc applications. Check out the attached technical sheet specific to Arc Flash or Electrical Specific PPE for more information.

FYI, the description is out dated and includes some outdated references. I know how Terry can be so please don't shoot the messenger! This vest is extremely effective at alleviating heat stress while wearing an arc flash suit.

Terry - Our original plan was to utilize the cool vests with employees that had experienced or were susceptible to heat stress, but as you mentioned most electric utilities (us included) have many locations such as underground vaults or enclosed areas that require some form of forced ventilation for cooling purposes alone.

Jim - Thanks for the information. The vest in your attachment does seem to "fit the bill" and I was able to locate several others after a little research. Our FR rule does have a few exceptions to allow workers to peel back some layers of clothing when conditions allow it but as you know there are just as many other situations that have no flexibility on the requirements, so we're hoping to find a comfortable, compliant, and cost effective solution.

Thanks again for the feedback,
Nathan

Nathan,

Do you all plan to wear the FR cooling vest underneath your work-wear?
