CSA Z259.10-18 pdf download – Full body harnesses.
1 Scope 1.1 General This Standard specifies requirements for the design, testing, performance, marking, and instructions 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 a) full body harnesses for use in recreational situations such as mountaineering; or b) full body harness accessories sold as attachments or aftermarket additional items for users such as tool holders, etc. 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 Tolerances Unless otherwise stated within this Standard, all units have an acceptable tolerance range of ± 2%. 1.5 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. 1.6 Units of measurement The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
3 Definitions The following definitions shall apply in this Standard: Back strap — a full body harness component that maintains the position of the shoulder straps on the lower back of the worker. Carabiner — a connector in the form of an oblong ring that incorporates a self-locking gate. Chest strap — full body harness webbing that maintains the position of the shoulder straps on the worker. Connector — a means for joining a component to a) another component; or b) an anchorage. Note: Examples of connectors include anchorage connectors, carabiners, D-rings, snap hooks, and soft loops. Connector, Class I — a connector that meets the requirements for Class I as defined in CSA Z259.12. Connector, Class II — a connector that meets the requirements for Class II as defined in CSA Z259.12. Controlled descent system — a collection of components that function as a primary system to descend a worker or to lower another worker from an elevation. Dorsal — the location on a full body harness that corresponds to the area on the back of the user that falls between elevations that are 50 mm (2 in) above and 50 mm (2 in) below the shortest line joining the undersides of the armpits (see Figure 11). D-Ring — a D-shaped connector intended for attachment to another connector. Energy absorber (EA) — any device that dissipates kinetic energy, limits deceleration forces during fall arrest, and does not return kinetic energy to the system or into the human body. Fall-arrest indicator — a device that indicates when a fall-arrest component has arrested a fall. Fall-arrest system (FAS) — a collection of equipment components configured to arrest a fall. Note: A fall-arrest system typically comprises components such as full body harnesses, lanyards, deceleration devices, horizontal lifelines, vertical lifelines, anchorages, and anchorage connectors.CSA Z259.10-18 pdf download.
