Portwest S773 Jacket: Multi-Risk Shielding Engineering, Bizflame™ Rain Technology and Weather Protection

The S773 is a piece of advanced technical equipment that achieves an unprecedented convergence of flame-retardant protection and complete waterproofing. Utilizing Bizflame™ Rain technology, this jacket is designed to protect workers in environments where thermal risk, electric arc, and exposure to extreme weather coexist. It is the ultimate solution for operators on offshore platforms, petrochemical facilities in high rainfall areas, and field electrical grid maintenance, where safety cannot depend on atmospheric conditions.

Critical Operational Capabilities

• Bizflame™ Rain Shielding System: Unlike conventional garments, this technology offers an inherent flame barrier that does not degrade after exposure to moisture or water. The fabric acts as an impermeable thermal shield, protecting the worker against sudden fire and radiant heat even in severe storms.
• Electrical and Static Risk Management: Designed to mitigate the dangers of electric arc, its structure dissipates energy in the event of an incident and prevents the accumulation of electrostatic charges, complying with the most demanding industrial safety protocols for environments with potentially explosive atmospheres.
• High-Performance Ergonomics: The jacket prioritizes technical mobility. Its pattern allows for the use of base layers without restricting the range of motion, while the design of the access points allows for precise manipulation of tools and electronic controls without compromising the waterproof seal.

Technical Structure Details

• Base Material: Bizflame™ Rain fabric (98% Flame-retardant Polyester, 2% Carbon Fiber), with high-performance waterproof coating.
• International Certifications: EN 343 (Class 3:1 - Rain Protection), EN ISO 14116 (Index 3 - Flame Protection), EN 1149-5 (Anti-static), EN 13034 (Type 6 - Chemical Splashes), IEC 61482-2 (APC 1).
• Tactical Configuration: Detachable hood with ergonomic adjustment, front closure with double storm flap, heat-sealed seams to prevent infiltration, and internal pockets for protecting communication devices.
• Operational Resistance: Material designed to maintain its flexibility and sealing capabilities even in sub-zero temperatures, resisting degradation from oils, greases, and common chemical agents in heavy industry.
