ISO 11393-2 is the globally recognized international standard for chainsaw protective clothing, specifying the protection coverage, structural design and cut-resistant performance of chainsaw trousers. It defines three design variants: Type A, Type B and Type C, tailored for different working scenarios and operators.When selecting chainsaw trousers, merely checking the cut resistance rating is insufficient. The ISO 11393-2 protection type must also be matched to deliver reliable leg protection against kickback hazards. Let’s take a look at the specific categories and how to pick the right chainsaw trousers for you.
Chainsaw operations carry severe hazards. Unexpected chainsaw kickback can lead to serious leg injuries, and ordinary workwear cannot withstand cutting from a running chainsaw. As the core international standard for chainsaw protective trousers, ISO 11393-2 establishes three protective construction types (Type A, Type B, Type C) based on protective coverage. It also serves as the fundamental requirement for CE certification of chainsaw protective apparel sold in the EU market.
Protection coverage: Protection extends from 20 cm above the crotch down to 5 cm above the hem. An extra 5 cm protective section is added on the left leg. Both front and rear panels are made of protective fabric. Recommended users: Fully trained professional forest workers for regular timber harvesting in woodlands. Features: One-piece full trousers with maximum coverage and no webbing cutouts. It delivers the most stable resistance against chainsaw impact. The top choice for field logging, offering ample safety margin for harsh forest working environments.
Protection coverage: The front protective area matches Type A, ranging from 20 cm above the crotch to 5 cm above the hem with the extra 5 cm reinforcement on the left leg. The rear part uses webbing instead of protective fabric. This is an over-wear chap design rather than integrated trousers. Recommended users: Operators for medium & light-duty tasks, such as homeowners doing garden pruning. Features: Easy to put on and take off, lighter weight and lower cost. It can be worn over regular pants. However, there is no protection on the rear side. It is only suitable for short-duration, low-risk yard work and NOT recommended for forest logging.
Protection coverage: Front protection runs from 20 cm above the crotch to 5 cm above the hem. Rear protection covers from 5 cm below the crotch down to 5 cm above the hem, providing chainsaw protection on both front and back thighs. Recommended users: Occasional chainsaw operators or users under special working conditions. Features: Protection covers both front and rear leg areas, with wider rear thigh coverage than Type A. Ideal for less experienced operators who may face multi-angle kickback risks, balancing versatility and safety.
Type A for professional logging, lightweight
Type B for home garden maintenance
Type C for occasional or non-professional chainsaw work
The Type A/B/C classification only describes protective area design, and is separate from chainsaw speed classes (Class 1/2/3). A valid complete protection solution requires checking both the type and speed rating.
Type B chaps are external wrap-around designs. Always verify that straps are securely fastened before operation; loose fittings will invalidate protection.
Once protective fabric is torn, snagged or washed repeatedly, the internal fibre structure degrades and cut resistance drops significantly. Replace garments promptly.
All ISO 11393-2 compliant chainsaw trousers offer passive protection. The cut-resistant fibres stall the chain upon contact, but they cannot eliminate injury risk entirely. Always wear complementary PPE including ear defenders, safety goggles and anti-slip work boots during operation.
