Rated to 20,000 volts, it combines a fully sealed non-vented shell with Koroyd impact absorption, Twiceme NFC emergency data, and a Fidlock magnetic chin strap. Full brim coverage on all sides. One size fits most, 53–63 cm. Available in 17 colors. Weight: [confirm 545g].\u003c\/p\u003e\n\u003ch3\u003eWhat safety standards does the SHK-1 Full Brim Non-Vented meet?\u003c\/h3\u003e\n\u003cp\u003eThe SHK-1 Full Brim Non-Vented is certified to ANSI\/ISEA Z89.1-2014 (R2019) Type I \u0026amp; Type II, Class E. Class E certification means the helmet is electrically rated to 20,000 volts AC — the highest electrical rating available under ANSI standards. Type II certification covers impacts from the top, front, side, and rear. The helmet also meets EN 12492:2012 covering shock energy absorption (Clauses 4.2.1.2–4.2.1.4), penetration resistance (Clause 4.2.2), retention system strength (Clause 4.2.3), and retention system effectiveness and roll-off (Clause 4.2.4).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eCertified to ANSI\/ISEA Type II standards (United States). Not certified to CSA Z94.1 Type II (Canada). Always verify helmet class matches your site's assessed electrical hazards before use.\u003c\/p\u003e\n\u003ch3\u003eWhy non-vented for electrical work?\u003c\/h3\u003e\n\u003cp\u003eA non-vented shell has no openings in the outer surface — eliminating any pathway for electrical conductivity through the helmet. Vented helmets, regardless of their electrical class rating, cannot achieve Class E certification because the vents create a potential conductive path. If your job site involves electrical hazards up to 20,000 volts, a fully sealed non-vented shell is required. The SHK-1 Full Brim Non-Vented is built specifically for those environments.\u003c\/p\u003e\n\u003ch3\u003eHow does the SHK-1 Full Brim protect against impact?\u003c\/h3\u003e\n\u003cp\u003eKoroyd's welded tubes crumple instantly on impact, absorbing maximum force and minimizing energy transferred to your head. Engineered to protect against both direct and angled impacts — may reduce the risk of suffering a life-changing injury. The full brim shell provides additional coverage over the standard brim, directing rain and debris away from the face and neck on all sides. ANSI-certified for industrial use.\u003c\/p\u003e\n\u003ch3\u003eWhat is Twiceme NFC and how does it work?\u003c\/h3\u003e\n\u003cp\u003eAn NFC chip embedded in the helmet shell stores emergency contact and medical information. First responders can access it instantly with any NFC-enabled device — no app required, no power source needed. Setup takes under two minutes through the Twiceme app. Information is stored on the chip itself, not in a cloud database, meaning it's accessible even without cellular signal on remote job sites.\u003c\/p\u003e\n\u003ch3\u003eHow does the chin strap system work?\u003c\/h3\u003e\n\u003cp\u003eThe Fidlock magnetic buckle fastens and releases with one hand, even with gloves on. Four anchor points distribute load evenly across the jaw and crown for a stable fit during dynamic movement. Adjustable nylon straps accommodate a range of head shapes. Available as a replacement part in M\/L and XXL.\u003c\/p\u003e\n\u003ch3\u003eWhat size SHK-1 Full Brim Non-Vented do I need?\u003c\/h3\u003e\n\u003cp\u003eThe SHK-1 Full Brim Non-Vented is one size fits most, with an adjustable range of 53–63 cm. The rear dial fit system and extendable front brow pad let you fine-tune the fit across that full range.\u003c\/p\u003e\n\u003cp\u003eWeight: 545g \/ 1.2 lbs \/ 19.2 oz\u003c\/p\u003e\n\u003ch3\u003eCertifications \u0026amp; Compliance\u003c\/h3\u003e\n\u003cp\u003eANSI\/ISEA Z89.1-2014 (R2019) — Type I \u0026amp; Type II, Class E\u003c\/p\u003e\n\u003cp\u003eEN 12492:2012 — Mountaineering equipment standard covering:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eShock energy absorption (front, lateral, and rear — Clauses 4.2.1.2–4.2.1.4)\u003c\/li\u003e\n\u003cli\u003ePenetration resistance (Clause 4.2.2)\u003c\/li\u003e\n\u003cli\u003eRetention system strength (Clause 4.2.3)\u003c\/li\u003e\n\u003cli\u003eRetention system effectiveness \/ roll-off (Clause 4.2.4)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarranty \u0026amp; Lifespan\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eManufacturer's warranty: 3 years\u003c\/li\u003e\n\u003cli\u003eField use lifespan: 3–5 years\u003c\/li\u003e\n\u003cli\u003eShelf life: Up to 10 years from manufacture date\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"US SafetyGear, Inc.","offers":[{"title":"Default Title","offer_id":41156495605824,"sku":"SHK1-FB-EY-FISHEL","price":117.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0553\/3479\/7376\/files\/Screenshot2026-05-27at1.32.40PM_05590868-36b6-4ff2-837a-4ee13fe04c95.png?v=1780491706","url":"https:\/\/ussafetygear.com\/ko\/products\/studson-shk-1-full-brim-non-vented","provider":"US SafetyGear, Inc.","version":"1.0","type":"link"}
