1 Scope 1.1 General This Standard specifies requirements for the performance, design, testing, marking, and information for use of full body harnesses. Full body harnesses are intended for use as body supports in personal fall arrest systems and in other work situations that involve the risk of falling. 1.2 Exclusions This Standard does not cover full body harnesses for use in recreational situations such as mountaineering. 1.3 Stipulation of design This Standard does not stipulate designs for full body harnesses, except insofar as design limitations are necessary to ensure safe and durable service. 1.4 Terminology In CSA Standards, "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; "may" is used to express an option or that which is permissible within the limits of the standard; and".can" is used to express possibility or capability. 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. 1.5 Units of measurement The values given in SI (metric) units are the standard. The yard/pound values given in parentheses are approximate and are for information only.
