How to Choose Chainsaw Protective Trousers: A Guide to US Standards, Classes, and Safety

Choosing the right chainsaw trousers is one of the most important decisions for anyone working with a chainsaw in the United States. This essential personal protective equipment (PPE) must meet strict American safety regulations to provide reliable protection. Understanding the differences in protection classes, coverage types, and key features will help you select gear that keeps you safe and compliant on the job.
Understanding US Chainsaw Protection Classes: What Do Class A, B, C & D Mean?
In the US market, chainsaw protective legwear is tested and certified against the ASTM F1897-20 standard. This standard defines different classes of protection based on performance levels. When selecting your gear, ensure it clearly states its ASTM certification and specific class.
  • Class A: Designed for general chainsaw use and provides a defined base level of cut resistance.
  • Class B: Offers enhanced protection for more frequent or demanding professional cutting tasks.
  • Class C: Provides high-level protection suitable for intensive forestry and arborist work.
  • Class D: Represents the maximum level of cut resistance for the most challenging and high-risk operating conditions.
Global Compliance: Built to the Highest International Standards
Our chainsaw chaps are engineered for professionals who demand verified, global safety. They are Classified by UL and carry multiple certifications, meaning they are rigorously tested to comply with major international standards, including:
  • US Standards: ASTM F1897, ASTM F3325 & OSHA 1910.266
  • European Standards: Full EN ISO 11393 series (Parts 2-6) with CE marking
  • UK Standards: UKCA marking for post-Brexit compliance
This WORLDWIDE STANDARDS certification guarantees that our protection meets or exceeds the specific regulatory requirements for professionals working across different regions.
Key Protective Features: More Than Just a Standard
Beyond certification, the construction and materials define real-world safety and durability.
  • 8-Layer Protective System: Utilizing advanced Swedish technology, our chaps combine 6 layers of high-tenacity cut-resistant fabric with 2 layers of shock-absorbing cushioning. This system is engineered to rapidly clog a chainsaw's drive mechanism, stopping the chain before it can cause severe injury.
  • Premium Durable Materials: The outer shell is made from tough 1050D pure polyester with a PU coating, offering excellent abrasion resistance, light waterproofing, and long-lasting wear. All components, from YKK/ITW buckles to 3M reflective stripes, are sourced from leading manufacturers for reliable performance.
  • Practical & Functional Design: Features include two secure pockets for tools and personal items, and high-visibility reflective stripes for essential safety in low-light conditions. We offer updated sizing (Large: 40-42" and Medium: 36-38") that fits most men and women, conforming to the current 2020 ASTM standards.
Care, Maintenance & Replacement: Ensuring Ongoing Protection
Your safety depends on maintaining the integrity of your PPE.
  1. Inspect Before Each Use: Check for cuts, tears, or contamination from oils and fuels.
  2. Clean Properly: Machine wash gently in cold water with mild detergent. Do not use bleach or fabric softeners.
  3. Air Dry Only: Never tumble dry or expose to direct heat, which can damage the protective fibers.
  4. Retire Immediately After Impact: If the chaps make contact with a moving chainsaw, they must be replaced—even if damage is not visibly apparent—as the internal protective layers may be compromised.
Conclusion: Invest in Certified, Professional-Grade Protection
For wildland firefighters, forestry professionals, and serious arborists, chainsaw trousers are vital lifesaving equipment. By choosing gear that is UL Classified, ASTM F1897-20 certified by class, and built with a multi-layer protective system, you invest in proven technology that protects your livelihood. Ensure your protection is up to standard before your next season on the fireline or in the forest.
