Portwest FR72 Sweatshirt: Thermal Comfort and Intrinsic Arc Flash Protection

The FR72 sweatshirt is an advanced piece of personal protective equipment designed for workers who require an additional thermal layer in environments with risks of flash fire or arc flash. Made with the technical fabric Modaflame Knit, this garment stands out for its ability to offer inherent flame-resistant protection, meaning that safety does not depend on external chemical treatments, but on the very nature of its fibers. Its high-visibility yellow color ensures that the user is detected in low-light conditions, maintaining a superior passive safety standard.

Why is this equipment vital for operations?

• High-Performance Thermal Protection: Its heavy-weight modacrylic knit fabric traps air to create an efficient insulating layer, maintaining stable body temperature during cold shifts without compromising operator agility.
• Certified Multi-Risk Safety: Protects against radiant, convective, and contact heat, in addition to possessing permanent anti-static properties, making it indispensable for personnel operating in refineries, chemical plants, or electrical maintenance areas.
• 360° Ergonomics and Visibility: The arrangement of premium reflective tapes, specifically designed to resist flame, ensures that the human silhouette is identifiable from any angle, reducing the risk of incidents in areas with machinery traffic.

Regulatory Compliance Analysis

This equipment complies with international standards EN ISO 11612 (Heat and Flame), EN 1149-5 (Antistatic), and IEC 61482 (Protection against electric arc). The fabric composition ensures that the garment does not ignite or structurally collapse during a thermal event, acting as a critical barrier to prevent severe burns to the user's skin.

• Material: Modaflame Knit (60% Modacrylic, 39% Cotton, 1% Carbon Fiber) 300g.
• Operational Design: Ribbed cuffs and waist for a perfect thermal seal that prevents cold air entry.
• Resistance: Permanent flame-retardant properties that are not affected by rough use or frequent washing.
• Sun Protection: UPF 40+ factor that blocks 98% of ultraviolet radiation.
