scope:

This standard specifies performance requirements for high-visibility vests for use by public safety workers. High visibility public safety vests are intended to provide conspicuity of the user in hazardous situations under any light conditions by day and under illumination by vehicle headlights in the dark.

Performance requirements are included for color, retroreflection, and minimum areas, as well as the suggested configuration of highly visible materials used in the construction of high-visibility public safety vests. Test methods are provided in the standard to ensure that a minimum level of visibility is maintained when items are subjected to ongoing care procedures.

Performance requirements for optional features are included in Section 6.

Purpose

Conspicuity is enhanced by high contrast between the vest ambient background and the work environment. This standard provides performance requirements of conspicuous materials to be used in high-visibility public safety vests and specifies minimum areas and placement of the materials.

This standard specifies minimum amounts of retroreflective materials, colors and placement of materials, for vests used to enhance the visibility of public safety workers.
