Maintaining Arc-Rated Clothing: Cleaning, Inspection, and Storage Tips

Proper maintenance of arc-rated clothing ensures long-lasting protection against electrical arc flash hazards. This guide covers cleaning, inspection, and storage tips to keep PPE effective and compliant.

Why Maintenance Matters

Arc-rated clothing provides critical protection during electrical work, but wear, contamination, and improper storage can reduce its effectiveness. Regular maintenance helps:

• Preserve thermal protection (ATPV rating)

• Extend garment lifespan

• Maintain compliance with NFPA 70E and IEC 61482 standards

Cleaning Tips

1. Follow Manufacturer Instructions

   • Always check the care label for machine or hand washing guidance.

2. Use Mild Detergents

   • Avoid bleach, fabric softeners, or harsh chemicals that can degrade fibers.

3. Wash Separately

   • Prevent damage from zippers, hooks, or rough fabrics in the same load.

4. Dry Properly

   • Air dry or use low heat if the garment allows; avoid high-temperature drying.

Inspection Tips

1. Visual Inspection Before Each Use

   • Check for tears, burns, holes, or worn areas

   • Inspect cuffs, seams, and reflective strips

2. Periodic Professional Testing

   • Some garments may require annual arc flash testing to ensure ATPV ratings are intact

3. Check Labels and Compliance

   • Verify that certification labels are intact and readable

Storage Tips

1. Keep Garments Dry and Clean

   • Avoid storing in damp or dirty environments

2. Avoid Sunlight and UV Exposure

   • Prolonged UV can degrade flame-resistant fibers

3. Hang or Fold Properly

   • Avoid sharp folds or heavy items on top that can damage fabric

Key Takeaways

Proper maintenance ensures your arc-rated clothing remains effective, compliant, and long-lasting, providing reliable protection against arc flash hazards.
