Portwest MV46 Trousers: Inherent Flame Retardant Properties, Multi-standard, and Maximum Operational Functionality

The MV46 trousers represent a cutting-edge technical solution for high-risk industrial environments. Made with inherently flame-retardant fabric that guarantees permanent protection unaltered after washing cycles, this personal protective equipment (PPE) has been rigorously certified to safeguard the user against thermal, electrical, and chemical risks, integrating a high-resistance textile architecture designed for demanding daily operations.

Technical Characteristics and Operational Capabilities

• Flame Resistance (EN ISO 11612): Their inherent flame-retardant nature provides a durable barrier against heat and flames, eliminating dependence on temporary chemical treatments.
• Electric Arc Protection (IEC 61482-2) and Welding (EN ISO 11611): Class 1 certification for welding work with protection against molten metal splashes and robust protection against the thermal effects of electric arcs (6.8 cal/cm²).
• Ergonomics and Structural Durability: Optimized design with triple-stitched seams, heavy-duty brass zippers, 9 functional pockets, and adjustable kneepad pockets that promote mobility and garment lifespan.

Safety Notice and Use Limitations

IMPORTANT: The trousers must be kept clean; the accumulation of flammable contaminants on the fabric can drastically reduce the level of flame protection. Modification or alteration is strictly prohibited, as it may invalidate CE-CAT III safety certifications and its antistatic dissipative capacity (EN 1149).

Maintenance and Care Instructions

• Washing: Wash at a maximum temperature of 60°C. CRITICAL PROHIBITION: Do not use bleach or detergents with oxidizing agents that may degrade the flame-retardant fibers.
• Drying: Tumble dry at a medium temperature. CRITICAL PROHIBITION: Do not air dry outdoors under direct and prolonged exposure to solar radiation to prevent premature fabric degradation.
• Ironing: Iron at a moderate temperature if necessary to maintain the integrity of the reflective tapes.
• Inspection: Inspect before each use for tears, punctures, or excessive wear on seams; any damage that exposes the skin or compromises the fabric requires immediate removal from service.
