Multi-Hazard Protection Built Into Every Fibre

Portwest's FR402 WX3 Modaflame trousers don't just meet flame resistance standards – they're engineered for comprehensive protection against heat, arc flash, chemical splash, and static discharge. Built for workers in welding, electrical maintenance, and high-risk industrial environments where multiple hazards are just part of the job. The Modaflame fabric delivers inherent protection that won't wash out or wear off.

Key Features:

• Modaflame Fabric Technology: 60% Modacrylic, 39% Cotton, 1% Carbon Fibre construction at 280g weight. Inherent flame resistance protects against radiant, convective, and contact heat plus electric arc exposure. The protection is permanent – woven into the fabric itself.
  
• Designed for Movement: Stretch panelling at key points, pre-bent knees, and stretch crotch gusset mean you can bend, kneel, and climb without restriction. Two-tier knee pad pockets accept standard pads for concrete work.
  
• Adjustable Leg Length: Extends from 31" to 33" so you get the right fit without expensive alterations. Heat-applied segmented reflective tape keeps you visible without compromising the flame resistance.
  
• Smart Storage System: Eight pockets including cargo and rule pockets. Everything has its place – tools, phone, measuring tape, and smaller items stay organised and accessible.
  
• Anti-Static and Chemical Resistant: Meets EN 1149-5 for static dissipation and EN 13034 for chemical splash protection. Non-magnetic construction won't interfere with sensitive equipment.
  
• Built Tough: Bartacked at all stress points. Side elastic waistband provides comfort without sacrificing durability. 40+ UPF sun protection for outdoor work.
  
• Comprehensive Certification: Meets EN ISO 11612 (heat and flame), EN ISO 11611 (welding), IEC 61482-2 (arc protection), EN 1149-5 (anti-static), EN 13034 (chemical splash), and ASTM F1959 standards.
