CHEMICALLY TREATED FLAME / FIRE RETARDANT
INHERENT FIRE Inherent fabrics are made from non- flammable / flame resistant materials that are woven or knitted into their fabric structures.
Fabrics that are chemically treated with a fire retardant chemical to slow down burning or self-extinguishing when exposed to flame.
PERSONAL PROTECTIVE CATEGORY (PPE)
ARC RATING Arc Thermal Performance Value (ATPV) defines the protection level against second and third degree burns (Arc Flash). The higher the number, the greater protection provided.
Personal Protective Equipment Category (PPE) are categories that are specified in the NFPA 70E Electrical Arc Flash guidelines. PPE 1 Clothing required to meet a minimum Arc rating of 4 Cal /cm 2 PPE 2 Clothing required to meet a minimum Arc rating of 8 Cal /cm 2 PPE 3 Clothing required to meet a minimum Arc rating of 25 Cal /cm 2 PPE 4 Clothing required to meet a minimum Arc rating of 40 Cal /cm 2
