Standards Development

Scope

This document specifies minimum performance requirements for overhead obstruction detection systems and secondary guarding fitted to mobile elevating work platforms (MEWPs). This document is intended to serve as a guide for manufacturers and designers of overhead obstruction detection systems and secondary guarding to achieve the following objectives:

— elimination or reduction of harm due to crushing accidents as a result of contact with obstructions; and

— establishment of criteria for design, manufacture, testing and performance; and

— establishment and understanding by manufacturers, engineers, and designers of their responsibilities.

This document is intended to be used in conjunction with ISO 16368.

The design and manufacturing requirements of this document apply to all secondary guarding manufactured on or after the effective date.

Purpose

Secondary guarding and overhead obstruction detection systems are currently being fitted to MEWPs in many countries. The design of these systems is not subject to any standardisation which results in a wide variation in understanding and effectiveness of what these systems do and how they are intended to reduce the risks of overhead crushing incidents on the work platforms of mobile elevating work platforms. The intention of developing a new standard for these systems is to provide requirements for the various systems. It does not intend to mandate the use of these systems.
