What is the Treadstone Spectrum-ID Cut Protection Colour Scheme?

This system has been designed to make life easier for workers, supervisors and inspectors on site. If you're a health and safety manager for example and you want to see what level of protection a staff member is wearing, simply look for the colour on the back of their Treadstone Gloves.

  • Red: Cut Level A - the lowest cut protection for low risk handling
  • Orange: Cut Level B - mid level cut protection for handling slightly sharper items
  • Green: Cut Level C through to F - the highest available protection. Level C is for thicker glass and metals, F is for the sharpest items people work with

Sizing Information
