Yes. The Studson SHK-1 Non Vented (standard brim) is a Class E helmet rated to withstand up to 20,000 volts. Its fully sealed ABS shell has no vents, so there are no conductive pathways — making it the right choice for electricians, utility workers, and anyone working in or around high-voltage environments. It meets ANSI/ISEA Z89.1-2014 (R2019), Type I & Type II, Class E. Always verify the helmet class matches your site's assessed electrical hazards before use.

The Studson SHK-1 Non Vented Safety Helmet meets ANSI/ISEA Z89.1-2014 (R2019), Type I & Type II, Class E, and EN 12492:2012 (a mountaineering standard covering shock absorption, penetration resistance, and retention-system strength and roll-off). Type II certifies both top and lateral (side) impact protection; Class E certifies dielectric protection rated to 20,000 volts. Note: it is certified to ANSI/ISEA Type II (United States) but is not certified to CSA Z94.1 Type II (Canada).

Both are Type II standard-brim (cap style) helmets with the same Koroyd impact core, Twiceme NFC, and Fidlock chin strap. The key difference is the class rating: the vented model is Class C (non-electrical) with openings for airflow, best for hot environments; the non-vented model is Class E, a fully sealed ABS shell rated to 20,000 volts for electrical or wet conditions. Choose vented for heat and breathability, non-vented for electrical exposure.

Koroyd is a welded-tube core structure built into the Studson SHK-1. On impact, its welded tubes crumple instantly to absorb maximum force and minimize the energy transferred to your head. It is engineered to protect against both direct and angled impacts, which may reduce the risk of a life-changing injury, and is ANSI-certified for industrial use.

Twiceme is an embedded NFC chip in the Studson SHK-1 that stores the wearer's emergency contact and critical medical information. First responders can access it instantly with any NFC-enabled device — no app required — saving time when seconds matter.

The Studson SHK-1 Non Vented comes in two adjustable sizes: L/XL (58–63 cm), the recommended universal size that fits most heads, and M/L (53–59 cm, limited availability). It uses a rear dial fit system for one-handed micro-adjustment, plus an extendable front brow pad for fine-tuning. A Fidlock 4-point chin strap with a magnetic buckle fastens and releases one-handed, even with gloves on.

Yes. The Studson SHK-1 Non Vented is lightweight at about 495 grams (per Studson) and is built to be comfortable through an entire shift. The rear dial fit system with an extendable front brow pad lets you dial in a secure fit, and the standard cap-style brim keeps the profile compact. It also features Ionic+ antimicrobial treatment for added hygiene during long wear.

Unlike a traditional Type I hard hat that only guards against top impacts, the Studson SHK-1 Non Vented is a Type II safety helmet protecting against both top and side (lateral) impacts. It combines a Koroyd welded-tube crumple core, an embedded Twiceme NFC medical/emergency chip, and a Fidlock magnetic 4-point chin strap that keeps the helmet secured during a slip or fall — modern head protection in a Class E electrical-rated shell rated to 20,000 volts.

The Studson SHK-1 Non Vented is accessory-ready and uses the same platform as the vented model. Compatible accessories include the SHK-1 Half Shield, a Telescoping Headlamp, Ear Defenders, and a Neck Shade, among others — letting you adapt one helmet to different job-site needs.

The Studson SHK-1 Non Vented carries a 3-year manufacturer's warranty. Studson lists a field-use lifespan of 3–5 years and a shelf life of up to 10 years from the manufacture date. As with any safety helmet, replace it after any significant impact regardless of age.

Industrial Safety Products (industrialsafetyproducts.com) sells the Studson SHK-1 Non Vented Safety Helmet with optional custom logo imprinting and free shipping. Logo printing is priced per location: $6.60 per location for a single color, or $10.90 per location for up to 4 colors. It requires a minimum order of 20 helmets and a set-up fee may apply; orders under the 20-unit minimum ship as non-logo items. Available in colors including White, Grey, Navy Blue, Red, and Black.

Because vents create conductive pathways. The Studson SHK-1 Non Vented uses a fully sealed ABS shell with no openings, so it can be Class E rated to 20,000 volts — providing dielectric protection that a vented Class C helmet cannot. That's why it's built for electricians, utility workers, and high-voltage job sites, and why you should always confirm the helmet's class matches your site's assessed electrical hazards.
