Inspect all lcks and tags prir t signing ff the Islatin Certificate. Ensure the Islatin Certificate is cmpleted and attached t the permit/hazard assessment. Inspect the wrk area and adjacent areas t determine they are in a safe cnditin. Ntify affected wrkers in adjacent wrk areas, including panel peratrs where applicable, when equipment is remved frm r returned t service. Fllw the islatin and lckut/tagut methd as determined by the hazard assessment and/r site specific prcedure. Attach their persnal lck(s) with an identifying tag and keep cntrl f the key(s) in their pssessin at all times. The fllwing requirements are applicable t all islatins and lckuts. Infrmatin specific t the type f lckut being perfrmed is included in the fllwing sectins. Wrk must nt prceed until the absence f energy and/r harmful substances has been verified. Wrkers must stay ut f the line f fire when testing fr absence f energy. If electrical wrk is t take place, islatin must be verified using a meter r apprved testing device as per the Electrical Wrk Prcedure. When an energy islating device is lcked ut, the lck must nt prevent access t ther energyislating devices that culd cause injury t wrkers. A permit and hazard assessment must be cnducted fr all wrk cmpleted under an islatin and lckut/tagut unless specifically exempted under an Exclusive Cntrl (Sectin 4.4). An Islatin Certificate must be prepared fr all islatins unless specifically exempted under an Exclusive Cntrl (Sectin 4.4).

7 4.4. Exclusive Cntrl Where breakers are used as part f an islatin (e.g. electric mtr islatin t wrk n a pump, etc.), the absence f vltage des nt need t be verified when a successful bump test has been perfrmed. Ensure piping systems are de pressured and islated Electrical Islatin Verificatin When perfrming electrical wrk requiring an electrical islatin: Cnduct a test t validate the absence f vltage; dcument test n the Islatin Certificate. Test must be cnducted by a qualified individual prir t starting wrk. The absence f vltage must be revalidated after a change in cnditins r after an extended wrk break where care and cntrl f the islatin has nt been maintained. It is nt required that revalidatin tests be dcumented n the Islatin Certificate. When a designated wrker(s) maintains sle exclusive cntrl f the islated piping r prcess system, the requirement t attach lcks and cmplete an Islatin Certificate will nt apply if all f the fllwing criteria are met: The wrker(s) is a full time equivalent emplyee. The wrker(s) has cntinuus cntrl f each energy islating device and each energyislating device is immediately accessible and identifiable t the wrker. The absence f energy has been verified. The energy islating device is secured in the islated psitin against inadvertent mvement. The task is cvered under an apprved hazard r risk assessment (e.g. Task Risk Assessment, etc.). A prcedure is available that includes the prcess fr securing the energy islating devices. The wrker(s) des nt leave the islatin unattended. Wrk in adjacent areas is nt creating additinal risk Individual Lckuts (Single r Multiple Wrker) Each energy islatin device (e.g. discnnect switch, circuit breaker r valve) must be lcked ut by all wrkers invlved in the task. Each wrker must attach an individually keyed padlck(s) and tag(s) t the islatin securing device fr all energy r prduct surces (e.g. circuit breakers, switchbxes, valves and cntrls). When multiple wrkers lck nt an islating securing device with a hasp r scissrs, the CPC Representative must attach the first lck and tag at each islatin pint. The number f lcks used at each islatin pint must equal the number f persns wrking n the jb Each lck must be identified n the islatin certificate. Rev Date: December 2014 Page 7 f 14 This dcument is uncntrlled when printed.

8 The wrker attaching their padlck is respnsible fr testing and cnfirming that the energy surce(s) has been effectively islated and there exists a zer energy state. This is accmplished by bump testing the equipment r verifying the absence f pressure. When there are multiple wrkers lcking nt an islatin pint, the CPC Representative will test and cnfirm, n behalf f all wrkers, that the energy surces have been effectively islated as abve. When the wrk is cmpleted, the CPC Representative must be the last persn t remve their lck/tag frm the lckut scissrs at each islatin pint when multiple wrkers are invlved. Each wrker must maintain exclusive care and cntrl f their key(s) at all times Grup Lckuts (Using Lck Bxes) Used when a number f wrkers are wrking n machinery r equipment at the same time, particularly, if a large number f energy islatin devices must be lcked ut. The CPC Representative must attach an islatin lck with a tag n the islatin securing device fr each energy islating device. Recrd the lck numbers fr each energy islating device n the Islatin Certificate. The key(s) fr each islatin lck will be placed int a secured lck bx. If using keyed alike lcks in a lck set, all keys fr the lck set must be accunted fr in the lck bx A secnd cmpetent wrker must verify that the energy surces have been effectively islated. The CPC Representative will place the padlck keys fr each islatin pint int a lck bx that is lcked by all wrkers. Nte: In British Clumbia, there must be a secnd qualified wrker wh will independently attach a secnd lck t each energy islating device when using a lck bx. This wrker s name must be identified n the Islatin Certificate as the persn attaching the additinal lcks. Once effective energy islatin has been tested and befre starting the wrk activity, each wrker invlved in the wrk will then attach their padlck with a tag t the lck bx. The number f lcks n the lck bx must equal the number f wrkers perfrming the task. Each persnal lck applied t the lck bx must be dcumented n the Lck Bx Register. The CPC Representative must be the last persn t remve their persnal lck frm the lck bx Cmplex Grup Lckuts Used fr larger prjects, facility turnarunds, r when intercnnected equipment r systems can be adversely affected. A written lckut prcedure and wrk plan that prvides an equivalent level f safety must be develped t ensure a level f prtectin equivalent t that prvided by the grup lckut prcess. The cmplex grup lckut prcedure and wrk plan must be apprved by a Directr f Inspectin (in Alberta) r The Bard (in British Clumbia).
