CAN/CSA-Z259.2.3-12 - Descent devices (Adopted ISO 22159:2007, first edition, 2007-05-15, with Canadian deviations)
PrefaceThis is the second edition of CAN/CSA-Z259.2.3, Descent devices, which is an adoption, with Canadian deviations, of ISO (International Organization for Standardization) Standard 22159 (first edition, 2007-05-15), entitled Personal equipment for protection against falls - Descending devices. The title has been changed for the CSA Standard to reflect the modification of the scope of the adopted ISO Standard.
ScopeThis International Standard specifies requirements, test methods, marking and information to be supplied by the manufacturer for descending devices. It also specifies some basic requirements for the descent lines to be used with the descending devices.
This International Standard is applicable to automatic and manually operated descending devices intended for use in the workplace in access, egress, work positioning and rescue systems. Various types and classes of descending devices are defined according to function and performance. These descending devices can be used in situations other than the workplace if adequate training and/or supervision are provided.
This International Standard is not intended to apply to descending devices used in leisure activities such as recreational climbing and caving, although its requirements can be useful in specifying such equipment.
NOTE Descending devices conforming to this International Standard can be designed for use by one or two persons simultaneously.
