Foreword

This Standing Safety Procedure (SAF), Hazardous Energy Control (HEC) Program, is supplemental to, and is authorized by ER 385-1-31, The Control of Hazardous Energy. ER 385-1-31 is the overall governing document for USACE HEC programs and it mandates that Districts will supplement its contents with specific procedures. This SAF is not intended to be the all-encompassing single source document for the HEC Program. This document strives to capture those processes which have been identified to establish consistent procedures and criteria for the safe and reliable control of hazardous energy at Portland District operated facilities. Instances not specifically identified in this document may very well require additional research into those documents identified in paragraph 3.0 of this document and possibly other industry standard publications to include manufacturer maintenance guidance.

Printed copies are for “Information Only.” The controlled version resides on the CENWP- OD SharePoint portal, Libraries at: https://intranet.usace.army.mil/nwd/nwp/od/pages/home.aspx been completed by observation of the first AP’s signature on the Safe Clearance order. If isolation points have been, added or temp lifted and restored, confirmation of the testing signature is recorded on the Safe Clearance Activity sheet.

11.5.6.5.6 APs other than the first APs to sign onto the clearance may test the isolation provided it poses no risk to APs already working at the job site protected by the clearance. For example, testing for voltage with a volt meter doesn’t add additional risk to APs already working on the circuit. Attempting to open a spill gate while other APs are working below it does increase the risk of danger to APs working below the spill gate.

11.5.6.5.7 Work that requires electrical energy to be isolated shall be made electrically safe via a Safe Clearance and tested as follows:

11.5.6.5.7.1 An adequately rated test instrument will be used to test each phase conductor or circuit part to verify it is de-energized.
