Portwest FR77 T-Shirt: Intrinsic Arc Flash Protection and Thermal Safety Management

The FR77 T-shirt is a high-engineering garment designed to act as a primary protective barrier in environments with severe thermal risks. Made with the technical fabric Modaflame (60% Modacrylic, 39% Cotton, and 1% Carbon Fiber), this piece stands out because its flame-retardant properties are intrinsic to the fiber, meaning they do not diminish or disappear with washing. Its long-sleeved design in high-visibility yellow ensures the operator is easily spotted while providing certified protection against heat and static.

Why is this equipment vital for operations?

• Permanent Antistatic and Flame-Retardant Protection: Unlike fabrics with superficial chemical treatments, the Modaflame blend offers natural flame resistance and continuously dissipates static electricity, which is fundamental for operations in classified areas.
• Thermal Comfort Management: The high cotton content allows for superior breathability and softness to the touch, facilitating sweat evaporation and reducing the risk of heat stress during demanding physical workdays.
• Optimized Passive Safety: The high-visibility yellow tone, combined with flame-resistant reflective tapes, ensures the worker maintains a 360° visibility standard, reducing the risk of being run over or incidents with mobile machinery.

Regulatory Compliance Analysis

This equipment complies with international heat and flame protection regulations, as well as arc flash protection standards. The construction of its elastic cuffs ensures that the sleeves stay in place, preventing fire or heat from penetrating the arms, while its UV protection factor protects the skin in outdoor work.
