Non-Vented Type 2 Safety Helmet with Koroyd — GE PPE GH501, ANSI Z89.1-2014 Class E & G

Koroyd® is an advanced impact-absorbing material made up of thousands of thermally welded tubes. On impact, the tubes crumple in a controlled way to absorb and dissipate energy more efficiently than traditional EPS foam. This results in better impact protection while keeping the helmet lighter and lower in profile.

Traditional safety helmets use EPS (expanded polystyrene) foam as the impact liner. Koroyd® absorbs energy more efficiently across a broader range of impact forces, allows for better airflow through its open-cell structure, and is generally lighter. This helmet weighs just 525 grams, contributing to reduced fatigue during long shifts.

Yes. The Koroyd® technology in this helmet has been shown to reduce heat stress by 4.51°C (8.11°F) compared to helmets without this technology, helping keep you cooler during extended wear.

This is a non-vented helmet. Non-vented helmets provide a complete shell without openings, which is required in environments where there are risks from chemical splashes, molten metal, or other hazardous materials that could enter through vents. If ventilation is a priority and your work environment permits it, check GE PPE's vented options.

The shell is made of ABS (Acrylonitrile Butadiene Styrene), a durable and impact-resistant thermoplastic commonly used in industrial safety helmets.

This helmet weighs 525 grams (approximately 1.16 lbs), which is lighter than many traditional hard hats, helping reduce neck fatigue during all-day wear.

The brim height is 145 mm, providing a lower profile than many conventional hard hats while still meeting Type 2 protection requirements.

This helmet features an adjustable ratchet system that allows you to dial in a precise, secure fit. The ratchet mechanism typically accommodates a head circumference range — consult the product's user manual or the GE PPE product page for the exact adjustment range (e.g., 53–63 cm).

Yes. It includes a 4-point adjustable chin strap that helps keep the helmet securely in place during movement or work in elevated positions, which is especially important for Type 2 side-impact protection.

A 4-point chin strap attaches to the helmet at four anchor points, distributing force more evenly and providing greater stability than a standard 2-point strap. This helps prevent the helmet from shifting or coming off during an impact or when working at height.

The ratchet suspension system allows for size adjustment to fit a range of head sizes. For the exact head circumference range supported, please refer to the user manual or the sizing information on the GE PPE product page. Typically, helmets with adjustable ratchet systems fit head circumferences of approximately 53–63 cm, but verify this with GE PPE's official documentation.

Color availability is not specified in the current product listing. Please check the GE PPE product page or contact the seller to confirm available color options before purchasing.

The product description mentions a constant adjustable ratchet suspension system. Whether replacement suspension parts are available separately should be confirmed with GE PPE or the authorized seller. Refer to the user manual for maintenance and replacement guidance.

Yes. This helmet is Class E rated, meaning it is tested for electrical insulation up to 20,000 volts AC. It is also fully dielectric with no metal components, making it well-suited for electrical utility and high-voltage work environments.

Yes. As a Type 2, Class E, ANSI Z89.1-2014 compliant helmet, it meets the requirements for most U.S. construction sites. Its side-impact protection (Type 2), electrical rating (Class E), and durable ABS shell make it appropriate for general construction, electrical work, and industrial environments.

The non-vented design of this helmet means there are no openings in the shell, which provides a barrier against splashes from above. However, for specific chemical resistance requirements, consult the user manual or GE PPE directly to confirm compatibility with the chemicals present in your work environment.

The 4-point adjustable chin strap and Type 2 side-impact protection make this helmet a strong choice for work at heights. However, always ensure the helmet is properly fitted and the chin strap is secured. Review your site's specific fall protection and PPE requirements as well.

Regularly inspect the shell, suspension, and chin strap for cracks, dents, discoloration, or any signs of wear. Clean with mild soap and water — avoid harsh solvents that could degrade the ABS shell. Follow the full care and maintenance instructions in the user manual included with the helmet.

ANSI Z89.1 and most manufacturers recommend replacing the suspension every 12 months and the full helmet every 2–5 years, or immediately after any significant impact, even if no visible damage is present. Check the user manual for GE PPE's specific replacement guidelines.

Most ANSI-compliant safety helmets include a date of manufacture stamp inside the shell to help you track the helmet's service life. Check the interior of the shell for this information.

Compatibility with accessories such as face shields, earmuffs, or lighting attachments is not specified in the current product listing. Contact GE PPE or the authorized seller to confirm which accessories are compatible with this helmet model.

The listed certification is ANSI Z89.1-2014 (US standard). Compliance with other international standards such as CSA (Canada) or EN 397 (Europe) is not stated in the product information. If you require compliance with specific international standards, contact GE PPE to confirm.

Warranty information is not included in the current product listing. Contact GE PPE or the authorized seller for details on warranty coverage and terms.

Yes, this product is listed under the GE PPE brand. For authenticity assurance, purchase only from authorized sellers and verify the certification markings inside the helmet shell upon receipt.

This helmet is well-suited for electricians, utility workers, construction workers, industrial plant operators, oil and gas workers, and any professional requiring Type 2, Class E head protection in demanding environments. Its Koroyd® technology and heat-stress reduction make it especially valuable for workers in hot or physically demanding conditions.

ABS shells can be sensitive to temperature extremes over time. The Koroyd® liner helps with heat stress reduction during wear. For specific temperature range ratings (operating and storage temperatures), refer to the user manual or contact GE PPE directly.

Traditional hard hats typically use EPS foam liners and offer Type 1 (top-only) protection. This GE helmet uses Koroyd® advanced impact technology, is Type 2 (top and side protection), is lighter (525g), reduces heat stress, and includes a 4-point chin strap — making it a more advanced head protection solution for modern work environments.
