Pro’s and con’s of treated FR fabrics

Enhanced comfort: Workers want to wear organic fibers like cotton and other cellulosics because they are comfortable — even after they are chemically treated. Treated FR fabrics are both lightweight and flexible.

 

FR protection mechanism: When exposed to direct flame, some treated FR fabrics rely on a chemical reaction to extinguish the flame. This reaction is triggered by the heat of the fire and the amount of time the fabric is exposed to the flame. Other treated FR fabrics char as their form of protection or off-gas to prevent combustion.

 

Longer lifespans: New advances in finishes have helped lengthen the lifespans of treated FR fabrics, as long as proper laundering procedures are followed. Treated FR garments, however, may be damaged by chlorine bleach, the combination of hydrogen peroxide (“oxygen bleach”) with hard water, or exposure to oxidizing chemicals in the workplace. Unfortunately, a wearer is not able to tell if a treated FR garment is no longer flame resistant simply by looking at it.

 

Inexpensive alternatives: With their shorter lifespans, treated FR fabrics tend to be less expensive upfront than inherent FR fabrics. This can be a primary driver in the PPE decision-making process.
