Fristads Flamestat GORE-TEX Jacket 4089 GXH, Hi-Vis Yellow/Navy
The Fristads Flamestat 4089 GXH is a hi-vis Class 3 GORE-TEX jacket built for people who work around energised switchgear in all weathers. It is approved to EN 61482-1-2 Class 2 (box test), and the main fabric carries an open-arc rating of ATPV 29.6 cal/cm² to EN 61482-1-1, so it sits at the higher end of arc-rated outerwear. Add EN ISO 20471 Class 3 visibility and EN 343 Class 3/3 rain protection and one jacket covers the arc, the weather and the hi-vis requirement on site.
Fabric and construction
The outer is a 2-layer anti-static GORE-TEX laminate, 52% modacrylic, 42% cotton and 6% polyester at 270 g/m², with taped seams.

Where it fits on site
This is the jacket for outdoor switching and substation patrols in Irish weather, where the authorised person needs arc protection and Class 3 visibility at once. Check the incident energy on your arc flash labels before specifying; 29.6 cal/cm² covers a wide range of MV and LV tasks, but your own study decides. See our wider arc flash protection range, and our explainer on what arc flash is if you are building a PPE specification from scratch.
