40 Cal Arc Flash Coverall Price & Specifications

In high-risk electrical environments, protecting workers from arc flash incidents is a non-negotiable safety priority. The 40 Cal Arc Flash Coverall is among the highest-rated Personal Protective Equipment (PPE) designed to offer Category 4 protection, safeguarding wearers from the extreme thermal energy released during arc faults.

What Is a 40 Cal Arc Flash Coverall?

A 40 Cal/cm² (calories per square centimeter) arc flash coverall refers to the garment's ATPV (Arc Thermal Performance Value). This measurement tells you how much incident energy the clothing can withstand before there’s a 50% chance of causing a second-degree burn. The 40 Cal level sits at the top tier of arc flash protection, generally required for environments with extreme exposure to electrical energy, such as electrical switchyards, substations, power plants, and heavy industrial plants.

Why Is 40 Cal PPE Important?

Working near high-voltage equipment exposes workers to dangerous arc flash events. A 40 Cal garment ensures maximum protection in such conditions. As per NFPA 70E, any task with an incident energy above 25 Cal requires Category 4 PPE. Not wearing this can result in fatal burns or long-term injuries.

How Much Does It Cost?

The price of a 40 Cal Arc Flash Coverall can vary depending on material, design (one-piece vs two-piece), and accessories.

  • Standard 40 Cal Coverall (One-Piece): Starting from $250–$400 per set

  • Two-Piece 40 Cal Jacket + Bib Set: $300–$500

  • Full PPE Kit (Coverall + Hood + Gloves): $600–$900

Essential Protective Wear for High-Risk Environments: From Arc Flash to Chemical Splash

 In high-risk industrial environments, safety is not optional—it's critical. Whether working around electrical hazards, molten metal, or hazardous chemicals, the right protective clothing can mean the difference between minor incidents and life-threatening injuries. Arc Flash Protection garments are designed to withstand intense heat and energy releases caused by electrical faults. These garments reduce the risk of burns and other serious injuries by creating a protective barrier between the arc and the wearer. Look for clothing compliant with recognized standards like NFPA 70E or IEC 61482. Metal Splash Protection is vital for industries like foundries and welding. Clothing in this category resists molten metal splash, preventing burns and skin damage. Materials are carefully engineered to repel or withstand high-temperature substances. Chemical Splash Protection ensures that workers handling corrosive or toxic substances are shielded from accidental spills or splashes. Thes...
