Yes. The Kishigo F506 is a dual-hazard long sleeve tee that combines ANSI/ISEA 107 Type R, Class 3 high-visibility with flame-resistant, arc-rated protection — so a single garment covers both visibility and FR requirements. It's built from a lightweight 6.95 oz FR modacrylic blend, carries a CAT 2 arc rating (ATPV 16 cal/cm²), and complies with NFPA 70E and ASTM F1506. That makes it a strong pick for utility, electrical, oil & gas, and roadway crews who need to be seen and protected from flame and arc-flash exposure at the same time. It ships with free shipping from Industrial Safety Products.

The Kishigo F506 meets or exceeds ANSI/ISEA 107 Type R, Class 3 (both the 2015 and 2020 editions) for high-visibility, and is flame-resistant to NFPA 70E and ASTM F1506 with a CAT 2 arc rating (ATPV 16 cal/cm²). "Type R" means it is rated for roadway and temporary traffic-control environments, and "Class 3" is the highest visibility level in the standard, requiring the most fluorescent background material and reflective tape, including coverage on the sleeves.

Yes. The Kishigo F506 is arc-rated at CAT 2 with an ATPV (Arc Thermal Performance Value) of 16 cal/cm², and it complies with NFPA 70E (the standard for electrical workplace safety) and ASTM F1506 (the standard for flame-resistant textiles for electrical arc exposure). CAT 2 covers many common arc-flash tasks up to that incident-energy level; always confirm the required arc rating in your site's arc-flash hazard analysis. It is made from an FR modacrylic blend and is a Class 3 hi-vis garment, so it delivers flame/arc protection and visibility in one shirt.

On the Kishigo F506, "CAT 2" is the arc-flash Personal Protective Equipment category, and "ATPV 16 cal/cm²" is the Arc Thermal Performance Value — the amount of incident energy (16 calories per square centimeter) the fabric can withstand while providing protection from second-degree burns. In practice it means the shirt is rated for arc-flash tasks up to that energy level under NFPA 70E, and it meets ASTM F1506 for flame-resistant electrical-arc clothing.

The Kishigo F506 is made from a lightweight 6.95 oz flame-resistant modacrylic blend — 50% modacrylic, 40% lyocell, and 10% Twaron (an aramid fiber). It is rated for 25 wash cycles and meets ASTM F1506 and NFPA 70E with a CAT 2 arc rating (ATPV 16 cal/cm²). It has solid-knit front and back construction, dark flame-resistant side panels for visual contrast, a left chest pocket, and 2" wide high-performance breathable reflective tape.

The Kishigo F506 comes in a full size range from M through 5X (M, L, XL, 2XL, 3XL, 4XL, 5XL) and includes a left chest pocket. It's a high-visibility yellow-green Class 3 long sleeve tee with dark FR side panels, so it fits most workers while keeping ANSI/ISEA 107 Class 3 visibility.

Machine wash the Kishigo F506 warm, with no bleach, air dry only, and do not dry clean or iron. Kishigo rates the garment for 25 wash cycles, so following these care instructions helps it maintain its ANSI/ISEA 107 Class 3 visibility and FR performance over its service life.

Both can be ANSI/ISEA 107 Class 3, but only the Kishigo F506 is flame resistant and arc-rated. A standard hi-vis long sleeve is usually made of polyester, which is not flame resistant. The F506 uses an FR modacrylic blend, carries a CAT 2 arc rating (ATPV 16 cal/cm²), and meets NFPA 70E and ASTM F1506 — so it protects against flame and arc exposure while a standard hi-vis shirt only provides visibility. Choose the F506 when workers face both visibility and flame/arc hazards.

The Kishigo F506 is available from Industrial Safety Products (industrialsafetyproducts.com), which ships it with free shipping. Optional customization is available through the listing's "Customize This Product" option, so crews can add branding to their ANSI/ISEA 107 Class 3, FR arc-rated long sleeve tees. It's offered in sizes M through 5X.
