When you’re shivering in the snow, the dangers of heat and flame probably aren’t the first things that come to mind. But even in cold weather, thermal hazards such as arc flash and flash fire pose a serious concern. In fact, when winter brings dry air and strong winds, it can literally help fan the flames. 

One of the most obvious ways to combat the cold is to bundle up in extra layers of clothing. But in environments where thermal hazards are present, it is important to ensure each of those layers is flame resistant (FR). A non-FR jacket worn over FR clothing can ignite and burn, injuring the wearer. On the other hand, an FR jacket worn over an FR shirt offers an extra layer of protection.
