The Hidden Risks of FR Contamination: How Oils, Chemicals, and Improper Washing Destroy Flame-Resistant Clothing

How Everyday Exposure and Simple Mistakes Can Quietly Compromise Your FR Protection

Your FR gear is there to protect you—but it can only do that if it’s in the right condition.

A little oil, the wrong detergent, or one hot dryer cycle can quietly break down the protection you’re counting on.

Let’s look at what puts your FR gear at risk, how to take care of it, and when it’s time to let it go.

 

1. Job Site Hazards That Can Compromise Your Gear

FR clothing is built for durability, but it’s not immune to the conditions it protects you from.

Common contaminants include:

  • Oils, greases, and fuels – These can saturate fabric fibers and increase flammability.
  • Solvents, acids, and corrosive substances – Can weaken fabric integrity and alter its FR properties.
  • Dust, debris, and welding residues – May wear down fibers or embed flammable particles.

You might not always see the damage—but that doesn’t mean your gear is still safe.

 

2. Laundry Mistakes That Undermine Protection

Proper laundering isn’t complicated—but it matters.

A single misstep can affect how well a garment performs.

Avoid These:

  • Bleach
  • Fabric softeners and dryer sheets
  • Detergents with brighteners
  • High heat drying

Do This Instead:

  • Use mild, fragrance-free detergent
  • Wash in warm or cold water
  • Dry on low heat or line dry
  • Wash FR gear separately from other clothing

These simple habits go a long way in preserving the protection built into your gear.

 

3. When to Retire FR Gear

Even the best-made gear has a lifespan—especially if it's been exposed to the wrong substances or worn down on the job.

Watch for These Signs:

  • Persistent stains from oils or chemicals
  • Stiff, faded, or discolored fabric
  • Visible damage like holes, fraying, or broken closures
  • Any exposure to bleach or fabric softeners

Repairs are not recommended. If there’s any doubt, replacement is the safer choice.

 

4. Good Habits to Extend the Life of Your Gear

  • Rotate multiple garments to reduce wear
  • Wash regularly to remove build-up
  • Store gear in a dry, clean, chemical-free area
  • Make sure your team understands proper FR care

Even durable gear benefits from consistent, simple care. It helps keep your clothing protective and compliant longer.

 

Conclusion: Care Is Part of the Protection

FR clothing protects against serious hazards—but only when it’s in good condition and properly maintained.

Contamination from job site materials and improper laundering are two of the most common ways that protection can be lost.

 

Stay aware. Follow care best practices. And when in doubt, replace your gear.
