What is the difference between FR and non-FR clothing?

The main difference between FR (flame-resistant) and non-FR clothing is their ability to resist flames and thermal hazards. FR clothing is designed to self-extinguish when exposed to flames, preventing or limiting burn injuries. On the other hand, non-FR clothing is more likely to ignite and continue to burn, increasing the risk of severe burns and injuries.

FR clothing is typically made from fabrics that are specifically engineered to resist flames and thermal hazards, such as aramids, modacrylics, and treated cotton. These fabrics are designed to either self-extinguish when exposed to flames or to form a protective char layer that insulates the wearer from heat.

Non-FR clothing, on the other hand, is made from materials that are more likely to ignite and continue to burn when exposed to flames, such as regular cotton, polyester, and nylon. While non-FR clothing may be cheaper and more comfortable, it is not suitable for workplaces where there is a risk of fire or thermal hazards.

In summary, the main difference between FR and non-FR clothing is their ability to resist flames and thermal hazards, with FR clothing offering greater protection against burn injuries in hazardous environments.
