Foreword

This Standing Safety Procedure (SAF), Hazardous Energy Control 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 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.

The proponent office for this document is the Operations Division Technical Operations Branch staff and any questions or comments should be directed to this office at:

Tags shall be treated as locks and shall only be removed by the II or DRII.

Tags shall never be bypassed, ignored, or otherwise defeated.

5) Lockboxes shall be kept in a secure location.

NOTE: Prior to starting any work on equipment under a Safe Clearance, isolation of all hazardous energy sources must be verified.

Verify that the individual who applied the personal lock is not at the facility.

Make all reasonable efforts to contact the individual to inform them that their personal lock will be removed.

Ensure that the individual will be informed of the removal before they resume work at that facility by signing the Abnormal Removal of a Personal Lock Form (Attachment 8).

Obtain written authorization from the RO or their Designee to remove the individual’s personal lock.

Documentation provided in Attachment 8 must be filled in and attached to the Safe Clearance as a permanent record of the action.

2) Abnormal Release of a Safe Clearance.
