Flame retardant gloves, FR snoods, flash hoods and balaclavas, not to mention FR undergarments and long johns: these are all FR accessories, yet the term Accessory does not do justice to the role these play.
These items of PPE are an integral part in layer-protecting your body from excesive cold, heat, flame and skin burn. By wearing these accessories with an FR coverall or FR jacket and antiflame trousers, you significantly improve your odds of survival, if in a fire.
Bizarrely, none of the EN or ANSI standards attempts to address the issue of SKIN BURN. It is skin burn that kills people. The older you are the more likely that Class 3 skin burn will kill you. Conversely, the more FR layers you wear, the less likely you are to get extreme skin burn. So, you need to look after yourself, in case others do not.
