THE COMPLETE GUIDE TO PROPERLY WASHING & MAINTAINING ARC FLASH PPE

Arc flash personal protective equipment (PPE) is designed to protect electrical workers from extreme thermal energy released during arc flash incidents. However, even certified arc-rated clothing can lose effectiveness if it is not washed and maintained correctly. Proper care is essential to preserve arc ratings, fabric integrity, and overall safety performance.

This guide explains best practices for washing, maintaining, and inspecting arc flash PPE to ensure long-term protection.

WHY PROPER CARE MATTERS FOR ARC FLASH PPE

Arc-rated garments rely on specialized flame-resistant fabrics to:

• Resist ignition

• Limit heat transfer

• Self-extinguish after arc exposure

Improper laundering can weaken fibers, reduce thermal performance, and compromise the garment’s ability to protect workers during an arc flash event.

STEP 1: FOLLOW THE GARMENT CARE LABEL

Always follow the manufacturer’s care instructions provided on the garment label. These instructions are developed to maintain:

• Arc rating performance

• Flame-resistant properties

• Fit and durability

Ignoring care labels is one of the most common causes of PPE failure.

STEP 2: USE THE RIGHT DETERGENTS

Avoid:

• Bleach

• Fabric softeners

• Harsh alkaline detergents

These products can damage flame-resistant fibers or leave residues that interfere with arc flash protection.

Best practice:
✔ Use mild detergents
✔ Choose detergents approved for FR and arc-rated garments

STEP 3: CONTROL WASHING & DRYING TEMPERATURES

Excessive heat during washing or drying can:

• Weaken fabric strength

• Cause shrinkage

• Distort garment shape

Recommended approach:

• Wash at moderate temperatures

• Tumble dry on low heat or air dry

• Avoid over-drying

Maintaining proper temperatures helps preserve arc-rated performance.

STEP 4: WASH ARC-RATED PPE SEPARATELY

Do not wash arc-rated garments with regular clothing. Residues from everyday laundry products can contaminate PPE and reduce protective effectiveness.

Rule:
✔ Wash arc-rated PPE separately
✔ Do not mix with non-FR garments

STEP 5: PROTECT FIT & COVERAGE

Improper washing can lead to shrinkage or loss of shape. Poor fit may expose skin or reduce coverage during an arc flash incident.

Check for:

• Tight sleeves or legs after washing

• Shortened garment length

• Restricted movement

Correct fit is a critical part of arc flash protection.

STEP 6: INSPECT PPE REGULARLY

Routine inspection helps identify early signs of damage. Look for:

• Holes, tears, or thinning fabric

• Loose seams or stitching

• Excessive fading or wear

• Damage to reflective or safety features

Replace garments that show significant wear or damage.

STEP 7: REMOVE CONTAMINATION PROMPTLY

Arc-rated PPE contaminated with oils, fuels, or chemicals should be cleaned as soon as possible. Contaminants can increase flammability and affect thermal performance.

Never store contaminated garments with clean PPE.

STEP 8: STORE PPE CORRECTLY

When not in use:

• Store garments clean and dry

• Avoid direct sunlight exposure

• Keep away from chemicals or heat sources

Proper storage helps preserve protective properties between uses.

FINAL THOUGHT

Arc flash PPE is a critical safety investment — but its protection depends on proper care and maintenance. By following correct washing procedures, using appropriate detergents, inspecting garments regularly, and replacing worn PPE, employers can ensure arc-rated clothing continues to deliver reliable protection when it matters most.

Proper care protects workers, extends garment life, and strengthens overall electrical safety programs.
