Scope 

1.1 Inclusions 

1.1.1 General 

This Standard specifies requirements for HVSA that is a) capable of signaling 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. 

1.1.2 Performance requirements 

Performance requirements in HVSA are included for a) colour; b) retroreflection and minimum areas, as well as for the configuration of the materials; c) the physical properties of background materials used in the construction of HVSA; and d) conspicuous materials. Specifies classes of HVSA, minimum areas, and placement of conspicuous materials are also addressed. Note: Conspicuity is enhanced by high contrast between clothing and the work environment against which it is seen. Test methods are provided in this Standard to ensure a minimum level of visibility is maintained when HVSA is subjected to ongoing care procedures. This Standard specifies minimum amounts of retroreflective materials, together with colour and requirements for placement of materials, for HVSA used to enhance the visibility and safety of workers. HVSA classes are identified, and appropriate markings for HVSA are recommended. 

1.2 Terminology 

In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
