Overview

• The GARIOX Flame Resistant Trouser Cat 2 is a navy blue work trouser made from 100% cotton, woven from fine-quality yarn treated with a permanent flame retardant finish, so the protection is part of the fabric itself. It carries an arc rating of ATPV 12 cal/cm² tested to ASTM F1959, which places it within NFPA 70E PPE Category 2, and it is certified for protection against heat and flame to EN ISO 11612:2015 (A1 A2 B1 C1 F1), for welding and allied processes to EN ISO 11611:2015 Class 1, and for flash fire to NFPA 2112, with a UL Listing. Pure cotton keeps the trouser soft and breathable through long shifts in the Saudi heat, and the navy shade hides everyday dirt and grease on site. The front closes with a heavy-duty YKK metal brass zipper built for repeated daily use, two side cross pockets give easy reach for the hands and small items, and two back pockets hold a wallet or work permit. An arc-rating label marked NFPA 70E | CAT 2 | 12CAL is sewn on the back for quick checks on site, the ergonomic cut gives a better fit, and all stress points are bar-tacked and reinforced for daily industrial use. The trouser is offered in sizes from S to 4XL. Available through Al-Najma Al-Wataniyah with guaranteed quality and fast delivery across Riyadh, Dammam, and all KSA regions.

Documentation & Standards

• The GARIOX Cat 2 trouser brings several protection functions into one garment. Its ATPV of 12 cal/cm², measured with the ASTM F1959 arc test method, indicates the amount of thermal energy the fabric blocks, and places the trouser within NFPA 70E PPE Category 2 for energised work. EN ISO 11612:2015 certification confirms limited flame spread (A1, A2) and protection against convective (B1), radiant (C1) and contact (F1) heat, while EN ISO 11611:2015 Class 1 confirms resistance to small molten metal splashes and short contact with flame during welding. NFPA 2112 certification covers protection against short-duration flash fire, a common requirement on oil, gas and petrochemical sites, and the UL Listing shows that the garment is evaluated by an independent third party.
• Additional reference standards for the Saudi market
• EN ISO 11612:2015 — protective clothing against heat and flame; the certified performance codes are A1 A2 B1 C1 F1.
• EN ISO 11611:2015 — protective clothing for welding and allied processes; Class 1 covers lower-hazard welding techniques.
• ASTM F1959/F1959M — the standard test method used to determine the arc rating (ATPV) of the fabric.
• NFPA 70E — the standard for electrical safety in the workplace that defines PPE Categories 1 to 4; Category 2 requires a minimum arc rating of 8 cal/cm².
• NFPA 2112 — the standard on flame-resistant clothing for protection of industrial personnel against short-duration thermal exposures from fire.
• ASTM F1506 / IEC 61482-2 — related performance specifications for arc-rated protective clothing, often cited alongside ASTM F1959 in electrical project specifications.

Supply Information

Frequently Asked Questions

Q1: Is this trouser suitable for NFPA 70E Category 2 tasks?

• Yes. NFPA 70E PPE Category 2 requires arc-rated clothing with a minimum arc rating of 8 cal/cm². This trouser carries ATPV 12 cal/cm², above that minimum. Tasks classified as Category 3 or 4 need an arc flash suit system rated at 25 or 40 cal/cm².

Q2: Can I wear these trousers with any shirt?

• For arc flash and flash fire protection, the upper body must also be covered by an arc-rated, flame resistant shirt or coverall. Category 2 work also calls for an arc-rated face shield and balaclava or hood, a hard hat, safety glasses, hearing protection, gloves and leather footwear. Any underlayer should be natural fibre such as cotton, never polyester or other meltable fabric.

Q3: Will the flame resistance wash out?

• No. The yarn is treated with a permanent flame retardant finish. Wash the trouser following its care label and avoid bleach and fabric softener, which can leave flammable residues or damage the finish.

Q4: Can I use these trousers for welding?

• Yes, for lower-hazard welding. EN ISO 11611 Class 1 covers techniques with light spatter and low radiant heat, such as gas welding, TIG welding and light MIG work. Heavy welding, overhead welding and work in confined spaces call for Class 2 garments or additional leather leg protection.

Q5: Do you deliver across Saudi Arabia?

• Yes. Al-Najma Al-Wataniyah delivers to Riyadh, Dammam, Jeddah, Jubail, Yanbu and all regions of the Kingdom, with project supply available for contractors and industrial facilities.
