STUDSON Achieves Dual Certification for SHK-1 Safety Helmet

Certification Enables Cross-Border Compliance for Workers in the U.S. and Canada

North American safety helmet innovator STUDSON has announced that its flagship SHK-1 Full Brim safety helmet has achieved dual certification under both Canadian CSA Standard Z94.1-15 (R2024) and American ANSI/ISEA Z89.1-2014 (R2019) at the ASSP Safety 2025 Conference in Orlando. The groundbreaking achievement makes the SHK-1 the first Type II safety helmet of its kind to provide seamless compliance for workers operating across the U.S.-Canada border, addressing a critical safety compliance and operational challenge.

Studson’s new helmet represents a significant milestone in industrial safety, particularly for workers in the construction, oil and gas, forestry, and mining industries operating in Canada and across the U.S.-Canadian border. To meet and exceed CSA Z94.1 while maintaining ANSI/ISEA Z89.1 certification standards, the project required rigorous materials testing, extensive structural analysis, and close collaboration with third-party certifiers to ensure compliance with impact, penetration, and environmental resistance criteria.

To achieve the dual certification, STUDSON worked closely with KOROYD, its provider of Advanced Impact Technology inside the helmet. KOROYD crumples on impact to absorb maximum force, reducing the risk of life-altering head injuries from both direct and angled impacts. The redesign required increased amounts of KOROYD material and a reduction in expanded polystyrene (EPS) foam, further improving upon the ventilation and breathability of the original SHK-1 Full Brim helmet.

The helmet also integrates Twiceme technology that stores emergency contact details and critical medical information for first responders during emergencies, along with data for occupational health and safety managers to better track and manage safety helmet inventory and worker certifications for regulatory compliance.

The dual-certified helmet includes the same comfort and usability features found in existing SHK-1 safety helmets, including the rear dial-fit system for easy adjustment and the four-point chin strap system with Fidlock magnetic buckle for one-handed operation even with gloves. The Class C version features enhanced ventilation for comfort, and both the Class C and Class E are available in a low-profile, full-brim design. The dual-certified SHK-1 Full Brim safety helmet remains compatible with the full range of STUDSON accessories, including half shields, full-face mesh shields, telescoping headlamps, and ear defenders.

The dual-certified SHK-1 will become available for purchase later this year.
