scope:

This Standard specifies requirements for occupational apparel that is

a) capable of signalling the user's presence visually; and

b) intended to provide the user with conspicuity in hazardous situations under any light conditions and under illumination by vehicle headlights.

Performance requirements are included for colour, retroreflection, and minimum areas, as well as for the configuration of the materials. Performance requirements are also provided for the physical properties of background materials used in the construction of high-visibility safety apparel. Test methods are provided in the Standard to ensure that a minimum level of visibility is maintained when garments are subjected to ongoing care procedures.

Purpose

Conspicuity is enhanced by high contrast between clothing and the work environment against which it is seen. This Standard provides performance requirements for conspicuous materials to be used in high-visibility apparel and specifies Classes of garments, minimum areas, and placement of these materials.

This Standard specifies minimum amounts of retroreflective materials, together with colour and requirements for placement of materials, for apparel used to enhance the visibility and safety of workers. Categories of high-visibility garments are identified and appropriate markings for apparel are recommended.
