scope:

This standard establishes requirements for the design, performance, testing, test methods, marking, instruction, maintenance and removal from service of descent controllers for users within the capacity range of 130 to 310 pounds (59 to 140 kg).

Purpose and Application

The purpose of this standard is to establish minimum requirements for automatic and manual descent controllers intended for use in the workplace in rope access, rope descent, and evacuation. Descent controller types are defined according to function and performance.

Before any descent controller shall bear the marking ANSI/ASSP Z359.9 or be represented in any way as being in compliance with this standard, all applicable requirements of this standard shall be met. Such compliance shall be established in accordance with the requirements specified in ANSI/ASSP Z359.7.

Users of active fall protection systems require proper training and instruction, including detailed procedures for the safe use of such equipment in their work application. Refer to ANSI/ASSP Z359.2, Minimum Requirements for a Comprehensive Managed Fall Protection Program for training requirements.
