Flame- and Arc-Flash-Protection Bib Overalls


Cotton/Nylon Fabric	Aramid/Modacrylic Fabric

These overalls meet NFPA 70E for protection against flames and electrical arc flashes. They’re adjustable for a snug fit that shields skin from hazards while keeping you mobile—tighten and loosen the suspenders and secure cuffs around boots with hook and loop straps. Choose a bib overall that meets the arc rated personal protective equipment (PPE) category required by your workplace. The higher the arc rating, the greater the flame resistance.

Find your waist size by measuring just above the top of your hip bone. Take all measurements over any clothing you expect to wear under these overalls.

Cotton/Nylon Fabric—Cotton/nylon overalls are rated Category 2 for protection against arc flashes, which is the most common rating for standard industrial applications. They are soft yet wear resistant, so they’re more breathable than modacrylic/aramid overalls. A water-resistant coating on these overalls keeps you dry. They have leg zippers, making it easy to pull the overalls over bulky boots. With hip slits on both sides, you can reach through to your pants pockets.

Aramid/Modacrylic Fabric—Aramid/Modacrylic overalls are rated Category 4 to provide the highest level of protection from arc flashes. Made from the same material as the outer layer of a firefighter’s jacket, these overalls are extremely durable.

Welding Bib Overalls

Made of flame-resistant cotton, these overalls shield your torso and legs when welding or working near sparks. They're covered in leather from chest to knees for added protection from heat and cuts. These overalls have elastic in the waist and suspenders, so you can bend and reach without restriction. Zippers at the bottom of each pant leg make it easy to slip them over your boots. To keep sparks from reaching your skin, use the hook and loop strips to secure the cuffs tight around your ankles. Swiftly remove these overalls with quick-release buckles on the suspenders.

Flame- and Arc-Flash-Protection Base Layers

Wear these fitted garments under clothing for an added layer of protection against intermittent exposure to flames and radiant heat. They meet NFPA 70E standards for protection against electrical arc flashes for personal protection equipment (PPE) category 1 or 2. Check the PPE category and minimum arc rating provided for your workplace, and then select all required clothing and personal protective equipment to meet the minimum arc rating. Arc rating measures a garment’s ability to insulate the wearer from burns; the higher the arc rating, the greater the flame resistance. All base layer materials are lightweight, breathable, and moisture wicking for added comfort.

They all comply with OSHA 29 CFR 1910.269 standards for flame and arc flash protection.
