When it comes to electrical safety, not all work shirts are created equal. Arc flash shirts must protect workers from extreme heat and electrical energy — while remaining comfortable enough for all-day wear. Here are the five key features every safety manager and worker should look for before buying.
Always start with the label. A compliant shirt must meet standards such as NFPA 70E, ASTM F1506, or EN ISO 11612.
Look for an Arc Thermal Performance Value (ATPV) of at least 8 cal/cm² (CAT 2), providing reliable protection for most maintenance and utility tasks.
True flame-resistant (FR) fabrics are inherently FR or treated for permanent protection. They will not melt, drip, or ignite even after 50+ industrial wash cycles.
Avoid garments labeled “flame-retardant” without certification — they may lose protection after a few washes.
Heat stress is a hidden hazard. Choose lightweight, breathable cotton or FR blends (around 190–240 g/m²) that allow airflow and moisture control.
Well-ventilated shirts help workers stay cool, focused, and compliant on the job.
Professional-grade arc flash shirts include:
Double-stitched seams and reinforced stress points
Adjustable cuffs and collars for secure closure
FR buttons or snaps instead of metal zippers
Durability ensures the shirt maintains structure and protection through tough working conditions.
For worksites with static or chemical risks, look for shirts that also meet EN 1149-5 (antistatic) or NFPA 2112 (flash fire). Dual-certified garments save cost and ensure all-round protection.
At DomexSafety.com, we design arc flash shirts that combine tested protection, breathability, and long-term durability.
Every garment meets EN ISO 11612, EN 1149-5, and NFPA 70E standards — keeping your team safe, comfortable, and compliant every day.
