What is Secondary Flame Resistant (FR) Protective Clothing?
Secondary single-use flame-resistant clothing is intended to be worn over primary flame-resistant protective clothing for several reasons:
- It protects underlying primary FR clothing from wear, tear, and damage.
-Primary flame-resistant clothing is often more expensive and intended for multiple uses, so protecting it helps extend its usage or “lifetime.”
-It can help reduce harm to the individual by providing an extra layer of defense against thermal hazards.
