Vented Type 2 Safety Helmet with Koroyd — GE PPE GH500, ANSI Z89.1 Class C

The Koroyd® layer works as an additional impact-absorbing liner inside the ABS shell. It complements the internal suspension system rather than replacing it. The combination of the rigid outer shell, the Koroyd® liner, and the suspension system together provide the full protection package.

The helmet weighs 525 grams (approximately 18.5 oz), making it lighter than many traditional hard hats and designed for all-day comfort on the job.

The helmet has a profile height of 145 mm. This lower profile is intentional — it reduces the chance of the helmet catching on overhead obstacles and keeps the center of gravity closer to your head for less neck fatigue during long shifts.

The product listing does not currently specify the exact hat size range or head circumference in centimeters or inches. We recommend contacting GE PPE directly or checking the product packaging for the adjustable size range before purchasing, especially if you have a larger or smaller head size.

The helmet features a ratchet adjustment system that lets you dial in the fit quickly with one hand. It also includes a 4-point adjustable chin strap for additional security, which is especially important in environments where you might be bending over or working at heights.

No, this helmet contains no metal components. This is useful in environments sensitive to metal contamination or near electrical equipment (though remember, the helmet itself is still Class C and provides no electrical protection).

Yes, this helmet is vented. The vented design is engineered to meet ANSI Z89.1-2014 Type 2, Class C standards, so ventilation does not compromise its certified impact protection. Note that vented helmets cannot achieve Class E or Class G electrical ratings — if electrical protection is needed, a non-vented model is required.

According to GE PPE, the vented design and breathability system can reduce heat stress by up to 8.11°F (4.51°C) compared to non-vented helmets. This makes it a strong choice for outdoor work in hot climates or in high-heat industrial environments.

The outer shell is made of ABS (Acrylonitrile Butadiene Styrene) plastic, a durable engineering thermoplastic known for its toughness, impact resistance, and ability to maintain performance across a range of temperatures.

ABS shells can degrade over time with prolonged UV exposure. Regularly inspect your helmet for discoloration, chalking, or brittleness — all signs of UV degradation. If any are present, replace the helmet immediately. Some users apply UV-resistant stickers or covers, but check GE PPE's guidance before doing so, as unauthorized modifications could void certification.

Inspect the shell and suspension system regularly for cracks, dents, chalking, brittleness, or any deformation. Replace the helmet immediately after any significant impact, even if visible damage is not obvious — Koroyd® crumples on impact and will not return to its original shape, meaning it has already absorbed energy and its protective capacity is reduced. Also follow GE PPE's recommended service life guidelines, which are typically found on the product label inside the helmet.

The product information does not specify which adhesives or solvents are safe for the ABS shell or Koroyd® liner. Some chemicals in sticker adhesives or paints can degrade ABS plastic. Check GE PPE's official guidelines before applying anything to the shell, as unauthorized modifications could compromise the helmet's integrity and void its certification.

The product listing does not specify which accessory slots or attachment points are included. Contact GE PPE directly to confirm compatibility with face shields, earmuffs, or lighting accessories before purchasing add-ons.

The helmet includes a 4-point adjustable chin strap. Whether it is fully removable is not specified in the available product information. Check with GE PPE or review the product packaging for details.

This helmet is well-suited for construction, general industry, manufacturing, forestry, landscaping, and other environments where lateral head impacts are a concern and electrical hazards are not present. Its vented design and heat-stress reduction make it particularly valuable for outdoor or high-heat work. It is NOT suitable for work near live electrical equipment due to its Class C rating.

OSHA's head protection standard (29 CFR 1910.135 and 1926.100) requires helmets that meet ANSI Z89.1. This helmet meets ANSI Z89.1-2014, Type 2, Class C, so it satisfies OSHA requirements for environments where Class C protection is appropriate. Always verify with your site safety officer that Class C is acceptable for your specific work environment.

The listing only references ANSI Z89.1-2014. CSA Z94.1 certification is not mentioned. If you are working in Canada and CSA compliance is required, contact GE PPE to confirm whether this model carries that certification.

The listing does not specify available colors. Check the GE PPE product page or contact the seller to confirm which color options are offered, as color coding is often used on job sites to indicate roles or departments.

The description states this helmet is 'award-winning,' but the specific award or awarding body is not identified in the available product information. For details on which award this refers to, contact GE PPE directly.

The country of manufacture is not specified in the available product information. Contact GE PPE or check the product packaging for this detail.

No warranty information is included in the current product listing. Contact GE PPE directly to ask about the warranty policy and service life recommendation for this model.

Wipe the shell and suspension with mild soap and warm water. Avoid solvents, gasoline, paint thinners, or harsh chemicals, as these can degrade the ABS shell. Inspect after each cleaning for any signs of damage. Do not store the helmet in direct sunlight or extreme heat for extended periods, as this can accelerate degradation.

The listing does not confirm whether replacement suspensions are sold separately. Contact GE PPE to ask about replacement parts, as using a compatible suspension is critical to maintaining the helmet's certified performance.

Traditional hard hats typically use an EPS foam liner or rely solely on a suspension system for impact absorption. This helmet adds a Koroyd® crumple-technology liner for more consistent and efficient energy absorption, offers Type 2 lateral protection, features a lower and lighter profile for improved comfort, and includes a vented design for heat stress reduction — all upgrades over a standard hard hat.
