CAN/BNQ 1923-450-M91 Leg Protective Equipment for Chainsaw Users

CAN/BNQ 1923-450-M91 Leg Protective Equipment for Chainsaw Users

Developed by the Canadian Standards Council (SCC), the purpose of the CAN/BNQ 1923-450-M91 standard is to define fabrication and minimum performance criteria for leg protective equipment worn by chainsaw users. However, the tests required to verify the conformity of an equipment with the requirements of this standard do not in all cases indicate the performance level of the product. Operators must be aware that the margin of protection will decrease if the product used is not in good condition. For example, signs of abuse or failure of leg protective equipment or one of its components.

The CAN/BNQ 1923-450-M91 standard offers three different designs for trousers with varying coverage areas:

  • Category A covers the front area from the crutches to 75 mm above the hem as well as the back of the leg from the knee to the ankle.
  • Category B covers the front only, from the crutches to 75 mm above the hem.
  • Category C is the front area from the crutches to 75 mm above the hem, plus an area surrounding 100 mm to the left of both legs.

There are other international standards for leg protection equipment for chainsaw users. However, there are very significant differences between standards globally and results obtained using one test method cannot be compared with another. These test methods are designed to create a benchmark test to compare products from different manufacturers. After all, these standards are designed to define the minimum requirements for leg protectors to protect chainsaw users from nasty accidents.

As the chainsaw runs, it creates a force and develops an energy of motion. As the speed increases, the kinetic energy increases exponentially. So it takes something to absorb all that energy to stop a fast moving chain. Fabrics and the fibers used are important in this regard. Today, para-aramid or polyarylate fibers with very high cut resistance properties are used.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides leg protection device testing services for chain saw users, within the scope of CAN/BNQ 1923-450-M91 standard, with its trained and expert staff and advanced technological equipment. gives.
