Overview

Portwest FR451 PW3 Modaflame Work HVO Class 1 FR Trousers - Overview

The Portwest FR451 PW3 Modaflame Work HVO Class 1 FR Trousers are inherently flame-resistant welding trousers with Class 1 hi-vis orange lower legs, built for welding and hot-work tasks where FR protection and visibility both matter. Reinforced panels at high-wear points and triple-stitched seams are built in for durability, and the flame-resistant qualities are in the Modaflame fibre itself, so they will not diminish with washing.

Frequently asked questions

Are these trousers rated for welding work?
Yes. They are certified to EN ISO 11611 Class 1 (A1+A2), the standard for protective clothing used in welding and allied processes.

What does the hi-vis class mean on the FR451?
EN ISO 20471 Class 1, the entry hi-vis class - the orange lower legs and reflective tape give visibility without the full hi-vis body coverage of a Class 2 or 3 garment.

Are they suitable for ATEX environments?
Yes. The non-magnetic, nickel and ferrous-free construction is suitable for wear in ATEX-classified hazardous environments.

Do they offer any chemical splash protection?
Yes. They carry an EN 13034 rating for limited protection against liquid chemical splash, alongside the FR and welding certifications.

How are the trousers sized?
By waist measurement, from 28in to 48in, with an extendable leg length of 31in to 33in.

How many pockets do they have?
Eight in total, including an easy-access cargo pocket, two back patch pockets, a rule pocket and top-loading knee pad pockets.

Can I add my company logo?
Yes. Embroidery and logo printing are both available to order - ask about trade-account pricing for bulk runs.
