Certified FR. Denim the Crew Already Wants.
NFPA 2112 Certified FR Jeans, Arc-Rated at CAT 2
Denim earns its place in an FR program by getting worn — consistently, without pushback. This collection covers oil and gas, electric utility, and welding roles with NFPA 2112 certified FR jeans at CAT 2, matched to the site's hazard assessment, with flame resistance designed to endure routine industrial laundering per manufacturer care instructions.

NFPA 2112 Certified FR Denim for Flash-Fire and Arc-Flash Hazards
Bulwark FR Jeans use heavyweight FR denim and stretch FR denim certified to NFPA 2112, providing flash-fire protection in the 5-pocket cut crews already know. For rosters that wear jeans by default, FR denim removes the friction between comfort and compliance — the garment that gets worn is the one that protects. The FR-treated cotton denim is warranted by Bulwark to remain flame-resistant when laundered per manufacturer care instructions.
CAT 2 Arc Ratings — FR Denim for Welding and Maintenance Work
Heavyweight denim construction delivers CAT 2 arc-flash protection (minimum 8 cal/cm²) suited to welding, electrical maintenance, and oil and gas work — with each style's ATPV listed on its product page. Standard and relaxed fits accommodate a range of builds and job-site preferences, and stretch styles keep mobility for crouching and climbing tasks.

What arc rating do Bulwark FR jeans carry? +
FR jeans in this collection are arc-rated at NFPA 70E CAT 2 (minimum 8 cal/cm²). Product pages list each style's ATPV, and the arc-flash risk assessment confirms the category the job calls for.

What is the difference between FR jeans and FR work pants? +
FR jeans use heavyweight FR denim in a familiar 5-pocket cut, arc-rated at CAT 2. FR work pants use cotton/nylon twill or inherent Nomex® fabrics with utility features such as cargo pockets and reinforced knees, spanning CAT 1 and CAT 2. Both are NFPA 2112 certified — jeans favor everyday familiarity, work pants favor utility.
Can FR jeans be worn as the only lower-body garment for NFPA 70E? +
FR jeans certified to NFPA 2112, with an arc rating that meets or exceeds the level in the employer's arc-flash risk assessment, can serve as the lower-body garment in an NFPA 70E PPE system. Confirm the specific style's ATPV against the required category before substituting FR jeans for FR work pants.
