Flame Resistance Specs & Standards
Flame Resistant ARC Rated/UL Certified Workwear
NFPA Standards Defined
The National Fire Protection Association (NFPA) is an international non-profit organization focused on preventing death and injury from fire and burns.
NFPA 70 E
NFPA 70E standard addresses electrical Arc hazards in the workplace and was developed to protect electrical workers on or near equipment that is capable of generating an Arc flash. Employers are required to complete their own testing to assess each worker's exposure rating. The level of Arc exposure is referred to as the Arc Thermal Performance Value (ATPV) or cal rating. These ratings are used in the chart below to help determine the best personal protective equipment each worker should use. Each garment should be clearly marked for which Cat. Flash PPE Category it complies with.
NFPA 2112 Standard on Flame-Resistant Garments for Protection of Industrial Personnel Against Flash Fire provides minimum requirements for the design, construction, evaluation and certification of flame resistant garments. The standard was developed to protect industrial workers, primarily in oil, petrochemical and manufacturing industries. Flash fires are unplanned exposures that typically last three seconds or less and spread rapidly through combustible dust, gas or vapors of an ignitable liquid. The standard does not cover fire entry or structural fire fighting activities and provides no personal protection from chemical exposures.
This Chart, based on specific job tasks, ranges from Cat. 1 (low risk) to Cat. 4 (high risk) and requires FR clothing with a minimum Cat. rating of 4. The Cat. category is used to determine the necessary Cat. rating of a garment worn during a given job task. Each of our garments are labeled with the appropriate Cat. rating they meet.
