Portwest Bizflame Work Hi-Vis Contrast FR Holster Trousers

The Portwest Bizflame Work Hi-Vis Contrast FR Holster Trousers (FR440) represent the pinnacle of multi-hazard workwear, combining comprehensive flame-resistant protection with high-visibility safety and the practical functionality demanded by professional tradespeople. These premium holster trousers deliver everything workers need in a single garment: certified FR protection, enhanced visibility in low-light conditions, and the storage capacity to keep essential tools within immediate reach.

Constructed from Portwest's innovative Bizflame Work fabric – a superior blend of 99% cotton and 1% carbon fibre – these trousers deliver exceptional flame resistance while maintaining the natural comfort and breathability that only cotton-rich fabrics can provide. The carbon fibre content is evenly distributed throughout the fabric, ensuring reliable anti-static properties that prevent dangerous electrostatic discharge in ATEX environments and areas where flammable gases or explosive atmospheres may be present.

The hi-vis contrast design features fluorescent yellow panels strategically positioned for maximum visibility, combined with navy contrast sections that resist showing dirt and wear in demanding work environments. This two-tone configuration allows the trousers to achieve enhanced visibility certification while maintaining a professional appearance suitable for supervisory roles and customer-facing work. Flame-resistant reflective tape provides additional conspicuity in low-light conditions, ensuring workers remain visible around moving vehicles and plant equipment.

What truly distinguishes the FR440 is its comprehensive holster pocket system, designed for workers who need immediate access to tools, equipment, and personal items without removing their safety harness or tool belt. The multi-functional holster pockets accommodate a variety of hand tools, measuring devices, and accessories, while remaining secure during climbing, bending, and physical work. Additional pockets throughout the garment provide organised storage for phones, documents, and personal effects.

The trousers feature top-loading kneepad pockets compatible with Portwest kneepads, allowing workers to insert protective padding when working in kneeling positions. The pre-bent knee design follows the natural leg shape for improved comfort during prolonged kneeling, reducing fatigue and joint strain. An easy-access multiway thigh pocket offers secure storage for mobile phones, keys, and frequently accessed items.

Triple stitching throughout the garment ensures maximum durability in the most demanding work environments. Key stress points receive additional reinforcement to extend garment life, while the contrast panelling uses strategically placed high-wear fabrics to maximise longevity in areas subject to abrasion.

The metal-free construction, featuring concealed studs and zip closures, makes these trousers suitable for ATEX Zone 1 and Zone 2 environments where metal components could create ignition sources. This nickel-free and ferrous-free design also benefits workers with metal sensitivities.

Technical Specifications

Understanding the Safety Standards

EN ISO 11612 – Heat and Flame Protection

This comprehensive standard specifies performance requirements for protective clothing against heat and flame. The ratings indicate: A1+A2 (limited flame spread), B1 (convective heat resistance), C1 (radiant heat resistance), and F1 (contact heat resistance). These trousers provide multi-directional protection against the thermal hazards encountered in industrial environments.

EN ISO 11611 Class 2 – Welding and Allied Processes

Class 2 certification indicates protection suitable for higher risk welding environments and techniques. The A1+A2 classification confirms limited flame spread properties, while Class 2 specifies enhanced protection against molten metal splashes and brief contact with flame, suitable for MIG, MMA, and TIG welding operations.

EN 1149-5 – Anti-Static Properties

This standard specifies material and design requirements for electrostatic dissipative protective clothing. The carbon fibre content provides reliable static dissipation, preventing dangerous charge build-up that could create ignition sources in flammable or explosive atmospheres.

EN ISO 20471 – High Visibility

This standard specifies requirements for high-visibility clothing to visually signal the wearer's presence in hazardous situations. The fluorescent background material and retroreflective tape ensure workers are visible both in daylight and when illuminated by headlights in darkness.

IEC 61482-2 – Arc Flash Protection

This standard covers protective clothing against the thermal hazards of an electric arc. Arc flash incidents can generate temperatures exceeding 20,000°C, and certified garments help protect workers from severe burns during electrical faults.

EN 13034 Type 6 – Chemical Splash

Type 6 classification provides limited protective performance against light spray of liquid chemicals, offering an additional layer of protection in environments where chemical exposure is possible alongside fire hazards.

Ideal For

The Portwest Bizflame Work Hi-Vis Contrast FR Holster Trousers are essential PPE for workers in:

• Electrical Utility Work – Power line maintenance, substation operations, transformer servicing
• Oil and Gas Operations – Upstream extraction, midstream pipelines, downstream refining
• Petrochemical Processing – Chemical plants, refineries, storage facilities
• Welding and Fabrication – MIG, TIG, MMA welding operations requiring hi-vis
• Roadside and Highway Work – Utility maintenance near traffic
• Railway Maintenance – Track work, signalling, overhead line maintenance
• Construction Sites – Where FR protection and visibility are both required
• Manufacturing – Steel production, metalworking, heavy industry
• Offshore Platforms – Deck operations, maintenance, drilling
• Emergency Services – Fire investigation, hazmat response support
• Utility Companies – Gas, electric, and water infrastructure maintenance
• Telecommunications – Tower work near power systems
• Mining Operations – Surface and underground work with fire hazards

Why Choose Hi-Vis FR Holster Trousers?

Multi-Hazard Protection in One Garment – Rather than compromising between flame resistance and visibility, these trousers deliver both certified protections simultaneously. Workers in environments requiring multiple PPE standards can meet all requirements with a single, comfortable garment.

Professional Tool Storage – The holster pocket design eliminates the need for separate tool belts in many applications, reducing encumbrance while keeping essential equipment within immediate reach. This is particularly valuable when working at height or in confined spaces where tool belts can catch on equipment.

Reduced PPE Complexity – Meeting multiple safety standards with one garment simplifies compliance management and reduces the total PPE investment required.

Enhanced Wearer Compliance – Workers are more likely to wear comfortable, functional garments consistently. The cotton-rich fabric and ergonomic design encourage all-day wear, maximising protection.

Visibility Without Compromise – The contrast design maintains professional appearance while achieving visibility certification. Navy contrast panels hide dirt and wear, reducing laundering frequency and extending garment life.

Care Instructions

To maintain flame-resistant properties, anti-static performance, and high-visibility characteristics:

• Machine wash at maximum 60°C using normal process
• Do not bleach
• Tumble dry at low temperature if required
• Iron at medium temperature (150°C max) if necessary
• Do not dry clean
• Empty all pockets before washing
• Do not use fabric softeners (can affect FR and anti-static properties)
• Wash separately from non-FR garments initially
• Inspect regularly for damage, contamination, or wear
• Retire garments showing signs of damage that could compromise protection
