Portwest FR21 Flame Retardant Overalls - Orange
Flame retardant overalls built from a lighter weight 210gsm cotton and carbon fibre fabric, designed for workers who need heat and flame protection without the bulk of a heavier boiler suit. The anti-static construction makes it suitable for ATEX zones and other environments where static discharge is a genuine hazard, common across offshore platforms, refineries, and petrochemical sites. Reflective tape on the arms and legs adds low-light visibility on top of the core flame and static protection.
How lightweight FR fabric solves the heat and comfort trade-off
Heavier FR overalls give strong protection but wear workers down over a long shift, especially outdoors or in warm plant environments. That fatigue leads to loosened cuffs, unzipped collars, and other small compromises that undo the protection the garment is supposed to provide. This 210gsm fabric keeps the same certified flame and heat resistance in a lighter build, so workers stay protected without needing to compromise for comfort.
Key Features
-
210gsm lightweight FR fabric: Cotton and carbon fibre blend that cuts weight compared to standard FR overalls, without dropping the certified heat and flame protection level.
-
EN ISO 11612 heat and flame certified: Covers limited flame spread, convective heat, radiant heat, and molten metal splash, the core standard for industrial FR workwear.
-
EN ISO 11611 Class 1 welding protection: Certified for welding and allied processes with lower risk exposure, spatter and short flame contact.
-
Anti-static to EN 1149-5: Dissipates static charge safely, a requirement in ATEX zones and around flammable atmospheres.
-
Reflective limb tape to EN 17353 Type B2: Adds retroreflective visibility on the arms and legs for low-light conditions.
-
10 pockets and radio loops: Rule pocket, sleeve pocket, two back patch pockets, two-tier knee pad pockets, and radio loops for tools and kit without extra bags.

Who is this for
This overall suits workers on offshore platforms, refineries, and petrochemical sites who need certified flame, heat, and anti-static protection but work long shifts in warm conditions. It's aimed at general operatives, maintenance crews, and lower-risk welders rather than workers facing high-current welding, molten metal handling, or maximum-tier arc flash exposure, those roles need a heavier, higher-rated FR garment.
Typical applications
-
General maintenance and inspection work on offshore platforms and rigs.
-
Petrochemical plant operations where anti-static clothing is a site requirement.
-
Low current welding and allied processes such as grinding and cutting.
-
Utility and energy site work where arc flash exposure is a possibility but not extreme.
-
Warm weather industrial work where standard FR overalls cause overheating.
-
ATEX zone entry requiring certified anti-static protective clothing.
-
General industrial site work needing basic flame and heat protection.
How to use
Step 1: Check the size guide and select a size that allows full range of movement without excess loose fabric.
Step 2: Fasten the concealed two-way zip fully before starting work in any flame or heat risk area.
Step 3: Adjust the hook and loop cuffs to seal the sleeve, an open cuff reduces the protection the garment provides.
Step 4: Store tools and small kit in the designated pockets rather than overloading pockets not designed for the load.
Step 5: Inspect the garment before each shift for tears, worn seams, or damaged reflective tape.
Common mistakes
-
Leaving cuffs or the collar open: This breaks the sealed protection the garment is designed to provide around exposed skin.
-
Ignoring damaged reflective tape: Worn or peeling tape reduces visibility in low light, replace the garment once tape coverage drops noticeably.
-
Washing outside the care label limits: Incorrect washing or drying can degrade the flame retardant treatment over time, always follow the label.
-
Assuming Class 1 welding rating covers all welding work: This rating suits lower risk exposure only, higher current or heavy spatter work needs a higher rated garment.
-
Treating this as a full hi-vis garment: The reflective tape meets EN 17353 for medium risk visibility, not the higher EN ISO 20471 standard for high-risk hi-vis work.
Safety
This garment meets EN ISO 11612 for heat and flame, EN ISO 11611 Class 1 for welding, EN 1149-5 for anti-static protection, and EN 17353 Type B2 for limb visibility. It is not rated for high-current welding, molten metal handling beyond E2 and F1 levels, or chemical splash. Anti-static protection only works as part of a fully earthed system, follow site procedures for correct grounding.
Maintenance
Wash at 60°C maximum. Follow the full care label for bleaching, tumble drying, and dry cleaning limits, incorrect washing can degrade the flame retardant and anti-static treatment over time. Inspect zips, cuffs, and reflective tape regularly and replace the garment once protective features show visible wear.
Frequently Asked Questions
Q: What level of heat and flame protection does this garment actually provide?
A: It's certified to EN ISO 11612 with a rating of A1+A2, B1, C1, E2, F1. That covers limited flame spread, a basic level of convective and radiant heat protection, and moderate resistance to molten aluminium and molten iron splash. It's a genuine, tested protection level, but it sits at the lighter end of the FR range rather than the heaviest duty tier, which is exactly why the fabric stays lightweight and comfortable for long shifts.
Q: What do all these EN standards on the label actually mean?
A: EN ISO 11612 covers heat and flame protection, the code combines flame spread, convective heat, radiant heat, and molten metal resistance into one rating. EN ISO 11611 Class 1 covers welding and allied processes at a lower risk exposure level. EN 1149-5 confirms the fabric safely dissipates static electricity, required in ATEX zones. EN 17353 Type B2 means the reflective tape on the limbs meets the standard for visibility in medium risk, low-light conditions. Together, these four standards define exactly what situations this garment is certified for.
Q: What is this garment NOT suitable for?
A: It's not rated for high-current welding, heavy spatter exposure, or molten metal handling beyond the E2 and F1 levels stated. It doesn't provide chemical splash protection, this is thermal protection only. The reflective tape meets EN 17353 for medium risk visibility, not the higher EN ISO 20471 standard, so it shouldn't be treated as a substitute for a dedicated hi-vis garment on high-risk sites.
Q: Why choose this over a heavier standard FR coverall?
A: A heavier FR coverall gives more protection headroom but adds weight and heat that wears workers down on long or warm shifts. At 210gsm, this fabric holds the same certified protection level while cutting bulk, which matters most on offshore and warm-climate sites where comfort directly affects how consistently workers keep the garment properly fastened.
Q: Can this be used in an ATEX zone?
A: Yes. The fabric is certified to EN 1149-5 for anti-static performance, one of the standard requirements for ATEX zone clothing. Anti-static protection depends on the whole system being correctly earthed, so follow your site's grounding procedures alongside wearing the garment.
Q: How do I know when to replace this garment?
A: Replace it once you see visible wear to the flame retardant fabric, damaged seams, a failing zip, or reflective tape that's peeling or no longer visible. Washing outside the care label limits accelerates this wear, so correct laundering extends the working life significantly.
