Our FLAME RESISTANT TROUSERS category covers practical FR workwear for daily use in demanding sites. The selection includes arc-rated pants for electrical work, welding-certified models for hot work, and high-visibility options for roadside and yard operations. Many styles are multinorm, combining EN ISO 11612, EN ISO 11611, and EN 61482-2 compliance to simplify purchasing and outfit management. For a broader overview of coordinated garments, visit Palosuojatut vaatteet.
Selected models meet EN ISO 11612 (heat and flame), EN ISO 11611 (welding), and EN 61482-2 (electric arc), with clear ATPV or EBT ratings. This helps safety managers align garments with site risk assessments.
Match the trouser’s arc rating to incident energy values and your PPE category. Combine with arc-rated jackets and base layers to achieve system protection. If values are unclear, request your site arc-flash study or contact our team.

Follow the label, avoid bleach and fabric softeners, and wash inside out. Industrial laundering is possible for many multinorm palosuojahousut when the process follows the manufacturer’s guidance. Inspect wear points and replace damaged items promptly.
Use FR or arc-rated base layers to maintain system performance. In winter, choose FR thermals; in summer, lightweight FR layers that manage moisture are best. Avoid non-FR synthetics.
Many FR trousers accept internal knee pads and include cargo pockets, hammer loops, and belt tunnels. Use FR-compatible accessories and avoid melt-prone plastics near heat sources.
Switch to a stretch model, check your waist and inseam, and ensure base layers are not over-restrictive. For ladder work or squatting, articulated knees and a gusseted crotch improve mobility.
Remove from service. Repair only if allowed by the manufacturer and site policy. When in doubt, replace the garment to keep protection and visibility reliable.
They suit areas with sparks, open flame, radiant heat, molten metal splash, or arc risk. Pair trousers with matching jackets and accessories for consistent protection across tasks.
