In the second part of our series on selecting appropriate personal protective equipment (PPE) for electrical work, we'll discuss the concept of "daily wear" and how it can simplify compliance while ensuring worker safety.

What is Arc-Rated Daily Wear?

Arc-rated daily wear refers to the clothing electrical workers wear every day as their uniform. Unlike standard work uniforms, daily wear is designed to protect workers during an arc flash incident. By using daily wear, workers can be prepared for most standard tasks, such as testing, troubleshooting, or voltage measuring, with minimal additional PPE.

Rozel's experts can help you select the most appropriate arc-rated daily wear for your workers, ensuring compliance with relevant standards and optimal protection against arc flash hazards.

The Two-Category Arc-Rated Clothing System

We typically recommend a two-category arc-rated clothing system, with daily wear providing a base level of protection (e.g., 8 cal/cm^2 ATPV) and additional PPE, like an arc flash suit, for higher-risk situations. While NFPA 70E 130.5(G) allows workers to stay out of an arc flash suit up to 12 cal/cm^2, finding shirts rated to this value can be challenging. As a result, a common daily wear ATPV is 8 cal/cm^2.

Rozel can assist you in implementing a two-category arc-rated clothing system tailored to your facility's specific needs and hazards.

Selecting Arc-Rated Daily Wear

When choosing arc-rated long-sleeve shirts and pants for daily wear, it's essential to look for the following:

  • ATPV (Arc Thermal Protective Value) rating on the garment
  • Compliance with ASTM F1959 (Standard Test Method for Determining the Arc Rating of Materials for Clothing)
  • Compliance with ASTM F1506 (Standard Performance Specification for Flame Resistant and Electric Arc Rated Protective Clothing Worn by Workers Exposed to Flames and Electric Arcs)

Be cautious of garments claiming to be FR (Flame Resistant) or compliant with NFPA 2112, as these do not necessarily meet the requirements for arc-rated clothing. Always ask for test results to verify the ATPV value, especially when ordering from unfamiliar sources.

Rozel's team can guide you in selecting arc-rated daily wear that meets all relevant standards and provides the necessary protection for your workers.

Trusted Manufacturers of Arc-Rated Daily Wear

Rozel can recommend trusted manufacturers and help you source high-quality arc-rated daily wear for your workers.

Selecting Appropriate Underlayers and Footwear

When choosing underlayers, avoid meltable fibers like acetate, nylon, polyester, polypropylene, and spandex, as per NFPA 70E 130.7(C)(9)(c). Opt for 100% cotton underlayers, including shirts, underwear, and socks.

For footwear, NFPA 70E 130.7(C)(8) and 130.7(C)(10)(e) require leather or dielectric footwear for exposures greater than 4 cal/cm^2. Choose 100% leather boots with an EH rating and consider safety toe and slip resistance based on your work environment.

Rozel's experts can provide guidance on selecting appropriate underlayers and footwear that meet NFPA 70E requirements and ensure optimal protection for your workers.

Additional Considerations for Daily Wear

  • Remove non-arc-rated items like smocks, hair nets, and hi-vis vests when performing electrical work
  • Avoid metal jewelry and opt for silicone wedding bands if necessary
  • Ensure outer layers, including jackets, are arc-rated to the appropriate level for the task at hand
  • Use non-metal frame safety glasses and non-melting belts (e.g., leather)

Rozel can help you develop comprehensive daily wear guidelines that address these additional considerations, ensuring a high level of safety and compliance for your electrical workers.

By simplifying electrical work wear with arc-rated daily wear and following guidelines for underlayers, footwear, and accessories, you can maintain a high level of safety and compliance. For more information on arc flash risk assessments and electrical safety training, contact the experts at Rozel.
