CEMA Safety Committee – SBP 002 E-Stop Application Guide

Developed by the CEMA Engineering Conference Conveyor Safety Committee, the guide is intended to be used in conjunction with ASME B20.1, and outlines clear objectives for stopping hazardous motion quickly and safely without introducing additional risks. It establishes common E-Stop guidelines applicable to all conveyors, then provides specific requirements for unit handling conveyors and bulk handling conveyors, including placement distances, accessible areas, pull-cord applications, and interlocking between control zones.

The document addresses hardware selection, control circuit design, inspection and testing, and special application areas, while emphasizing the importance of risk assessment when applying or deviating from the guidelines. Numerous examples of typical conveyor areas and equipment are included to support consistent, practical application across a wide range of conveyor installations.

This publication is advisory in nature and is provided free of charge as a service to the conveying industry.
