NWWP 385-1-2011 May 2012SAFE CLEARANCE PROGRAM FOR THE CONTROL OF HAZARDOUS ENERGYChapter 3 – Policies and Rules3-1. GENERAL. The intent of this policy is to protect personnel, equipment, and theenvironment from damage through the use of HECP procedures. All energy sourcesshall be controlled before performing work, service, or maintenance on equipment. Incircumstances requiring safe clearances, personnel and resources shall not beconsidered protected until all HECP procedures and special instructions have beencompleted.a. A copy of the AHA (NWW Form 385-1) (see appendix B) shall be submittedwith the safe clearance request.b. Use lockout where isolation points are capable of being locked out. Tagsshall always accompany locks.c.locked.Tagout only is permitted when isolation points are not capable of beingd. Train personnel on the purpose and application of the HECP and associatedprocedures.e. Coordinate servicing and maintenance activities when more than oneemployer, workgroup, or facility is involved or affected.f.Perform periodic inspections to assure continued program compliance.g. All modified, rehabilitated, or new equipment shall be capable of acceptinglockout devices.h. Employees will be notified of their rights and responsibilities with regard toreporting unsafe conditions and/or procedures.3-2.PROCEDURAL REQUIREMENTS.a. Before any task is performed, the worker shall determine whether theprovisions of paragraph 3-1 require a safe clearance. If one is required, personnel andequipment shall not be considered protected until all applicable measures of the HECPare completed.b. Only qualified personnel (Issuing Individual or Designated Alternate) shall bepermitted to perform the switching, valving, and tagging steps of the safe clearance.3-1

NWWP 385-1-2011 May 2012c. Issuing Individuals may receive safe clearances issued to the position for thefollowing conditions:(1) Line terminal clearances on tie lines and supply lines to and fromoutside utilities or the power marketing agency, BPA, to establish safe workingconditions within areas of high voltage equipment energized by these authorities. (Seeappendix G for BPA Accident Prevention Manual, Section S-6, Switching and ClearanceProcedure.)(2) To temporarily hold defective equipment out of service in emergencyconditions or prevent operation of malfunctioning equipment that might be damagedif operated.(3) In cases where emergency repair work is needed in order to restorecritical equipment to service and no Authorized Individuals are available to takeclearances.d. Requests for safe clearances should be made a minimum of 24 hours inadvance to give the Issuing Individual time to prepare. Large, complex, or missionessential clearances will typically require additional time to prepare, review, and toschedule outages. Professional consideration on behalf of both the requester and theIssuing Individual shall be observed.e. The following entries in the Station Log Book shall be in red ink:(1)Request of the safe clearance.(2)Issue of the safe clearance.(3)Adding a clearance point.(4)Installation of TPGs.(5)Adding TPG tags (see appendix B).(6)appendix B).(7)f.Temporary lifts and re-hangs of clearance points and TPG tags (seeChange of PAI on a multi-shift safe clearance.The following entries in the Station Log Book shall be in green ink:(1)Release of a safe clearance.(2)Release of TPG tags (see appendix B).3-2

NWWP 385-1-2011 May 2012(3)Removal of TPGs.(4)Release of a clearance point.g. Written standard HECP procedures, including switching orders, shall bedeveloped at each work site for all equipment supplied with multiple sources ofhazardous energy.h. Canned clearances should be used as a starting point or reference for therequested clearance, not a final trusted solution.i. The Responsible Official or designated alternate shall grant approval for theremoval from service of any equipment that may affect the mission of the project.j. All verbal communications shall be repeated back to avoid misunderstanding.This shall include the safe clearance number, equipment under safe clearance, changesto be made, and other relevant information.k. Prior to beginning work, all Affected Personnel should verify that stored orresidual hazardous energy is isolated, relieved, bled off, disconnected, restrained orabsent of voltage.l. All safe clearances shall have a Group Clearance Form (Master Tag) (seeappendix B) attached to the PAI copy of the Safe Clearance Order Form (see appendixB) to support the requirements for changes of status and group safe clearances.m. Locks will be used on all isolation points capable of being locked out. Safeclearance locks will only be applied to isolation points that have been positioned andhave a tag hung. Tags may be hung on the lock shank in the case of personal lockouts.n. When isolation points are not capable of being locked, then tagout only ispermitted. When tagout alone is used, the following conditions shall be met:(1)Personnel shall be instructed in the limitations of tags.(2) When a safe clearance tag (ENG Form 1925) (see appendix B) isattached to an isolation point, it shall be treated as being a locked point and shall neverbe operated with the tag attached.(3)Tags will be placed so they are readily identifiable as an isolation point.(4) Additional means shall be employed to provide a level of protectionequivalent to that provided by a lock. This can consist of any of the following:(a) Opening both the energy isolating circuit breaker and itsassociated disconnect.3-3

NWWP 385-1-2011 May 2012(b)Removal of a circuit element (i.e., a fuse).(c)Racking out or removing the circuit breaker.(d) Opening and applying a tagout to the circuit breaker (energyisolation device), opening the associated control switch or circuit, and applying a tagoutdevice to it.(e) Placing a blocking mechanism over the operating handle of adisconnect so that the handle is blocked from closing the circuit.(f)Grounding the circuit upon which work is to be performed.o. Computer software, or any other type of programming, shall not be used asan isolation point.p. The safe clearance lock sets shall be stored and maintained by the IssuingIndividuals. A safe clearance lock set will be issued to the PAI for isolation pointlockout. All excess locks will be placed in the Group Lock Box. After the safe clearancehas been released, the complete safe clearance lock set will be returned to the IssuingIndividual.q. Safe clearance lock boxes and Group Clearance Forms (Master Tag) shallnormally be located in a specified location as identified in appendix F.r. The PAI’s personal lock will be the first on the Group Lock Box and the last tobe removed.s. The PAI is not required to sign on to the Group Clearance Form (MasterTag), but will be cognizant of all Affected Personnel signing on to their safe clearanceand of the status of all work to be performed.t. All Affected Persons must coordinate with the PAI prior to signing onto asafe clearance. The PAI need not be present for Affected Persons to sign on to theirGroup Clearance Form (Master Tag) if they have signed on previously. Lackingcoordination, and in the absence of the PAI, written approval to sign onto the clearancemust be obtained from the PAI’s supervisor and provided to the Issuing Individual.u. Temporary lifts shall be of short duration.v. For diving operations, both the Government dive inspector and the dive crewsupervisor shall be issued a safe clearance.w. A Corps Quality Assurance Representative (QAR), when authorized, may beissued a safe clearance. The QAR shall not receive a safe clearance for a contractor.3-4

NWWP 385-1-2011 May 2012x. Safe clearance violations are taken very seriously since they can result ininjury, damage to equipment, or loss of life. The Responsible Official shall ensure thatalleged violations are investigated. Violators of this program may require training andretesting.3-5

In an emergency (i.e., imminent threat tolife or limb), the Responsible Official or the designated representative may modify orsuspend any of these HECP requirements temporarily as may be considered necessaryto permit proper handling of the specific emergency. The Appendix D provides anexample to assist each project in developing their own Personnel Authorizations. Thisdocument will include the Responsible Official and designated representative.4-2. SAFETY OF PERSONNEL. In handling such emergencies, safety of human lifeshall be given predominant consideration.4-3. EMERGENCY SWITCHING. If emergency switching is required and the PAI isnot on site or not available to be notified, the Issuing Individual or designee may performemergency switching. If the Issuing Individual is incapacitated, any qualified personwho is knowledgeable on the equipment may perform the emergency switching.4-1
