When the difference between safety and danger is measured in seconds, what you wear matters.
For workers facing heat, flame, and electrical hazards daily, FR clothing & supply is a life-saving necessity.
But what exactly is FR clothing? How do you ensure it meets safety standards?
And where do you find a reliable supplier? Let’s break it down.
What Is FR Clothing? (And Why It Matters)
FR clothing stands for “flame-resistant clothing.” Unlike regular workwear, these garments are specifically designed to resist ignition, self-extinguish after exposure to flame, fabric disintegration, and minimise burn injuries.
Some may understand FR clothing as “flame-retardant” clothing, which refers to chemically treated fabric rather than inherently non-flammable material. However, the terms are often used interchangeably.
FR-treated cotton, aramids such as Indura, Nomex, Kevlar, and modacrylics are the most commonly used materials for these specialised garments.

They offer varying levels of protection to suit different industry needs and are tailored to meet the standards required for different types of FR clothing.
Industries that require FR clothing include:
- Firefighting and emergency services
- Oil and gas industry workers
- Electrical utilities or electricians
- Welding and metalwork
- Research lab workers
It’s a fair question: ‘What is FR clothing, and why not just wear thick cotton?‘ The key difference lies in how these materials handle and react to heat and flames.
Ordinary fabric, like cotton, is flammable and has a prolonged burning time. Though thick, tightly woven cotton may slow down ignition, it still poses a significant risk by exposing the skin to flames and increasing the likelihood of severe injuries.
In some cases, materials can even melt into the wound, worsening the damage. FR clothing, on the other hand, acts as a protective barrier, reducing the intensity of burns and giving workers critical seconds to escape harm.
Regardless of the material, one must be aware that FR clothing is NOT fireproof. And no garment can offer complete protection against fire.
Instead, these specialised uniforms are designed to mitigate risk and provide crucial protection in hazardous environments.
Sourcing FR Clothing: What to Look For
Different ratings of FR clothing provide different levels of defence against flames, explosions, and thermal injury exposure.
Choosing the right FR clothing & supply goes beyond the rack of thick-looking garments. Whether you’re sourcing for your workforce or assessing manufacturers, here’s what to consider:
- Fabric Selection: Decide between inherent fabrics (naturally flame-resistant) like Kevlar, Nomex, and wool, and treated fabrics (given flame-resistant properties through chemical treatment).
- Compliance with Standards: Different regions have specific standards for fr clothes, for instance:
- United States: NFPA 2112 — Developed by the National Fire Protection Association, primarily for the oil and gas industry.
- Europe: EN ISO 11612 — Covers protective clothing for workers exposed to heat and flames.
- Canada: CAN/CGSB 155.20 — Focuses on protection against flash fires.
- Australia/New Zealand: AS/NZS 4824 — Designed for wildland firefighting gear.
- Asia: Varies by country, but many adopt EN ISO 11612 or NFPA 2112 as benchmarks.
- Middle East: Often follows NFPA 2112 due to the prevalence of oil and gas industries in the region.
- Russia: GOST R standards regulate protective clothing, addressing thermal protection and flame resistance.
- Comfort and Fit: As with standard work wear, fr clothing for specialised workers will also need breathability and mobility for daily tasks.
For such demands, moisture-wicking and breathable fabric like aramids or FR-treated cotton blends are most recommended, while natural fibers with softness like regular cotton are used for underlayers to further enforce comfortable skin contacts and easy slip on.
For optimal mobility and safety, sleeves should fully cover the wrists and be securely fastened. Garments should also feature reliable fasteners to ensure full coverage and protection.
- Durability: It goes without saying that jobs requiring clothing as work wear is often labour intensive and demanding, which will require regular change of clothings and repeated washing.
In most cases, inherent fire-resistant fabrics tend to last longer, whereas treated fabrics can lose effectiveness over time as the treated surface is washed off.

- Supplier Reliability:
Crafting garments for high-risk jobs requires highly responsible makers, as they play a crucial role in the entire FR clothing and supply process.
The key is to partner with manufacturers or suppliers who understand industrial demands and consistently deliver quality.

Testing for Standards: Trust but Verify
Even if a product is labelled FR-rated or a manufacturer claims expertise in flame-resistant clothing, proper testing is never excessive when it comes to ensuring workers get the protection they deserve.
A few tests to verify FR clothing’s safety and performance include:
- Vertical Flame Test: Measures how fabric reacts when exposed to a vertical flame, assessing its ability to resist ignition, self-extinguish, and limit flame spread.
Key factors include after-flame time (how long it burns after the flame is removed), after-glow time (how long it glows after burning stops), and char length (the extent of the damaged area). Shorter times and smaller char length indicate better flame resistance.
- Arc Flash Testing: Evaluates the fabric’s resistance to sudden electrical arcs.
- Thermal Manikin Test: Simulates real-life burn scenarios to assess protection levels.

The Hidden Challenge: How to Wash FR Clothing
While both offer protection, inherent fabrics tend to last longer, whereas treated fabrics can lose effectiveness over time, especially after repeated washing.
FR clothing is an investment for safety, hence it’s too costly to have it thrown around in the washer like the regular old t-shirt.
Here’s your list of Dos and Don’ts for cleaning FR clothes you might want to relay to your customers:
✅ DOs:
- Take the label tag seriously: Some FR clothing brands have specific “how to wash FR clothing” instructions. Be sure to read them carefully before cleaning your garments.
- Remove Stains Before Washing: Dab out stains or pre-soak the stain with liquid detergent before putting the garment in the washer.
- Use Mild Detergent: Detergent, NOT soap. Opt for a pH-neutral detergent without bleach or fabric softeners.
- Warm Water, Gentle Cycle: Use warm water (not hot) and a gentle cycle to avoid damaging the fibres.
- Wash inside out: Turn the garment inside out to wash.
- Wash Separately (Optional): Prevent contamination by washing FR clothes separately from regular laundry.
❌ DON’Ts:
- No Bleach or Fabric Softeners: These chemicals can break down FR properties.
- Avoid High Heat: Skip high-temperature washing and drying to prevent fabric damage — tumble dry on low or hang dry instead.
- No Starch or Anti-Static Sprays: These leave residues that can reduce flame resistance.
- Don’t Overload the Washer: Proper cleaning requires space for water and detergent to circulate.
- Skip the Home Remedies: Avoid DIY stain removers or harsh scrubbing that can degrade the fabric.
Last but not least, if you notice tears or unremovable stains from flammable substances start to build up, it’s a sign that the garment may need replacing to ensure continued protection.
Your Burning Questions, Answered
Q: How often should FR clothing be replaced?
A: It depends on wear and tear, but regular inspections and following manufacturer guidelines are crucial.
Signs like thinning fabric, holes, or compromised stitching mean it’s time for a new set.
Q: Can I repair damaged FR clothing?
A: Minor repairs are acceptable if done with FR-rated materials and thread. However, major damage means replacement is necessary.
