Change in job assignment, change in machines, equipment or processes that present a new hazard, or when there is a change in the energy control procedure. Authorized employees must be retrained if there are changes to OSHA regulation 29 CFR or the UIC Control of Hazardous Energy program. Affected employees must be reminded on an annual basis via , on-line, or classroom training not to remove another employee s lock or tag. 6.0 Control of Hazardous Energy Procedures and Process UIC personnel are only permitted to work on de-energized equipment following the UIC Control of Hazardous Energy (Lockout/Tagout) Program. Documented Equipment Specific Lockout Tagout Procedures are to be developed initially by an authorized employee and EHSO representative. The procedures must be approved by a Chief or Assistant Chief before they are posted on the equipment. A new procedure must be updated and approved by the department when there are process changes that impact the current LOTO procedure. These procedures must be maintained, made available, and accessible for the authorized employees 8

9 and auditors of this program. Appendix A Equipment Specific Lockout Tagout Procedure Template must be used. Equipment-Specific Lockout-Tagout Procedures are required for equipment or processes if one or more of the following are identified: The equipment or process has a potential for stored, residual, or re-accumulation of energy. The equipment or process has more than one energy source. If the equipment or process has one energy source, the isolation and locking out of that energy source will NOT completely de-energize and deactivate the unit. The equipment or process is NOT isolated from its energy source and locked out during servicing or maintenance. (Tagout Operations require documented procedures as they are not locked) A single lockout device will NOT achieve a locked-out condition. The lockout device is NOT under the exclusive control of an Authorized Employee. The service or maintenance creates hazards for other personnel. There have been accidents involving the unexpected activation or re-energization of the unit. EXCEPTION - Minor tool changes and adjustments, and other minor servicing activities, which take place during normal production operations, are not covered by this program if they are routine, repetitive, and integral to the use of the equipment for production, provided that the work is performed using alternative measures which provide effective protection Equipment Specific Lock-Out/ Tag-Out Procedures must include and are not limited to: A specific statement of the intended use/purpose of the procedure. Specific procedural steps for shutting down, isolating, blocking, and securing machines or equipment to control hazardous energy. Specific procedural steps for the placement, removal, and transfer of lockout devices or tagout devices and the responsibility for them; and Specific requirements for testing a machine or equipment to determine and verify the effectiveness of lockout devices, tagout devices, and other energy control measures Additional elements as listed on the UIC Equipment Specific Lockout Tagout Procedure Template In the event a documented Energy Control Procedure does not exist for equipment that will be worked on, an authorized employee can conduct a review of the equipment that is to be Locked and Tagged Out and can develop a procedure in order to service the equipment. This procedure should be reviewed with a supervisor or foremen prior to the work being initiated. In the event the authorized employee needs assistance with the Lockout Procedure, they can contact their supervisor or foreman for help. (See Appendix C) 9

10 Lockout/Tagout Required Process Whenever it is necessary for UIC personnel to be involved in the maintenance or servicing of equipment or machines with a potential exposure to hazardous energy, the following steps must be followed, in order. 1. Notifications 2. Preparing for shutdown 3. Performing shutdown 4. Isolating equipment 5. Discharge of residual energy 6. Locking/tagging devices 7. Energy verification 8. Maintenance/Servicing 9. Restoring power Details on each of these steps is included in the Authorized Employee training. Abandoned Lock/Tag or Removal by Someone other than Authorized Employee Placing the Lock If the authorized employee is not available or the lock has become abandoned, the device may be removed under the direction of the Chief and appropriate Foreman (if applicable), provided that all measures are taken to ensure the following: Verification via phone or text with the authorized employee who applied the lock to confirm he is not at the facility. All reasonable efforts to contact the authorized employee have been made to inform him/her that the lockout or tagout device has been removed. The authorized employee has knowledge that the lock/tag has been removed prior to resuming work at the facility. Temporary Removal of Lockout /Tagout Devices: In situations in which lockout or tagout devices must be temporarily removed from the energy isolating device and the machine or equipment energized to test or position the machine, equipment, or component thereof, the following sequence of actions shall be followed: Clear the machine or equipment or tools and materials Remove employees from the machine or equipment area. Remove the lockout or tagout devices. Energize and proceed with testing or positioning De-energize all systems and reapply energy control measures per the documented LOTO procedure to continue the servicing and/or maintenance. 10

11 Energy Control Procedures Energy Control Procedures are developed to outline the scope, purpose, authorization, rules, and techniques to be utilized for the control of hazardous energy, and the means to enforce compliance including, but not limited to: A specific statement on the intended use of the procedure; Specific procedural steps for shutting down, isolating, blocking, and securing machines or equipment to control hazardous energy; Specific procedural steps for the placement, removal, and transfer of lockout and tagout devices and the responsibility for them; and Specific requirements for testing a machine or equipment to determine and verify the effectiveness of lockout devices, tagout devices, and other energy control measures. Group Lockout/Tagout: When more than one trade or an external contractor works on a machine that needs to be locked out, each employee and contractor (if applicable) must put their lock and tag in or on the group lock box following the procedure below. Group lock boxes are provided at each safety station. Lock boxes are a convenient way to manage multiple individuals working on a piece of equipment that is locked out. An authorized UIC employee must take primary responsibility for all UIC employees and contractors working under the protection of a group lockout or tagout device (i.e. the Operating Engineer would lock-out all required energy sources). The employee taking primary responsibility for the lockout is to lock out each energy source and then place the keys to the locks in the lockout box. Each authorized employee working on the equipment shall affix a personal lock and tag to the group lockbox when he or she begins work, and shall remove those devices when he or she stops working on the equipment being serviced. When all authorized employees remove their personal lock and tag, the UIC employee who took responsibility for the group lockout may then remove the key(s) from the box and restore energy to the equipment. Below is a short video explaining how a group lockout box works: Picture of a Group Lockout Box 11

12 Shift or Personnel Changes: The Chief or Foreman is to assure specific procedures are utilized during shift or personnel changes to ensure the continuity of lockout or tagout protection, including provision for the orderly transfer of lockout or tagout device protection between off-going and oncoming employees. If an employee has not finished a job at the end of the shift, he/she may leave their lock and tag on the equipment. However, they should inform their Chief or Foreman they are leaving their lock and tag on the piece of equipment and confirm they will be assigned to finish the job the next day. If the same employee cannot be assigned to finish the job the next day, he must remove his lock the next day in the presence of the employee now assigned to the job. The new employee assigned to the job will then apply their own lock and tag. Lockout Locking Device Requirements: Durable: Lockout devices shall withstand the environment to which they are exposed for the maximum period of time that exposure is expected. Standardized: Lockout devices shall be standardized within the department in at least one of the following criteria: color; shape; or size. Locks used for lockout at UIC should be red in color. Substantial: Lockout devices shall be substantial enough to prevent removal without the use of excessive force or unusual techniques, such as with the use of bolt cutters or other metal cutting tools. Identifiable: Lockout devices shall indicate the identity of the employee applying the device(s) The Authorized Employee has the only key for his or her lock (No Duplicates) Use of Locks Chiefs, Assistant Chiefs, Foreman and Authorized Employees shall maintain a supply of lockout devices specific for their trade and area of expertise. Locks that are used for lockout operations are to be kept with the employee and at the departmental designated safety station(s) and used only for lockout operations. Locks shall remain on equipment during the duration of the service and maintenance operations except for shift changes and troubleshooting. Locks are required to be applied and removed by the authorized employee who applied the lock. Each authorized employee must have his/her own lock. Tagout Tag Equipment Requirements Tagout devices print and format shall be standardized for each department. Tags are to have the authorized employee s contact information identified on the tag. 12

13 Tagout devices shall be constructed and printed so that exposure to weather conditions or wet and damp locations will not cause the tag to deteriorate or the message on the tag to become illegible. Tags shall not deteriorate when used in corrosive environments such as areas where acid and alkali chemicals are handled and stored. Tagout devices shall warn against hazardous conditions if the machine or equipment is energized and shall include a statement such as: Do Not Start, Do Not Open, Do Not Close, Do Not Energize, or Do Not Operate. Tagout devices, including their means of attachment, shall be substantial enough to prevent inadvertent or accidental removal. Tagout device attachment means shall be of a non-reusable type, attachable by hand, selflocking, and non-releasable with a minimum unlocking strength of no less than 50 pounds and having the general design and basic characteristics of being at least equivalent to a one-piece, all environment-tolerant nylon cable tie. Tag Out Operations Requirements An approved tag will be placed on the hasp of each padlock used for the lockout. Tags are placed or applied by the authorized employee conducting the LOTO operation to notify affected and other personnel of the inherent danger and including but not limited to the following information: Authorized employee name Date and Time of Lockout Operations Authorized employee cell phone Tagout Operation Only (Used in Lieu of a Lockout/Tagout Operation) NOTE: WHERE THE EQUIPMENT CAN ACCEPT A LOCK, A TAG MUST BE UTILIZED. A tagout alone must be approved by the Chief or Foreman, or their designee of the department and the following requirements are to be met: Procedure(s) are written, available, communicated, and used that provide equal protection as a lockout operation against potential start- up of energy and for the authorized employee(s) conducting the LOTO operations. The tagout device is attached at the same location that the lockout device would have been attached, and the authorized employee and supervisor demonstrate that the tagout procedure will provide a level of safety, equivalent to that obtained by using a lockout. The authorized employee and supervisor must demonstrate full compliance with all tagoutrelated provisions of the control of hazardous energy standard, AND provide one of the following or equivalent safety measures: o removal of an isolating circuit element, 13

14 o blocking of a controlling switch, o opening of an extra disconnecting device, o or the removal of a valve handle to reduce the likelihood of inadvertent energization. Periodic Audits The Chief, Assistant Chief, Foreman, or Supervisor is to ensure authorized employees participate in the annual audits of LOTO procedures coordinated by EHSO. The purpose of the audits is to ensure the procedures are still accurate and are well understood by employees. The audit shall identify the equipment or process on which the energy control procedure was being utilized, the date of the audit, the employees included in the audit, and the designated authorized employee performing the audit. The point of this audit is to ensure the employee is able to properly lockout an energy source and the procedure is still accurate. The LOTO Audit form in Appendix B can be used for these audits. The designated personnel completing the audits are to comply with and complete the following: The procedure review is to be conducted by a person knowledgeable about the lockout/tagout standard other than the one(s) utilizing the energy control procedure being inspected. Complete review on an annual basis to assure the requirements of the procedure are being followed. Like equipment with similar energy sources can be grouped and counted as one inspection. Document corrections or deviations identified during the audit on the procedure audit form. Provide documented corrections or deviations to the Chief, Assistant Chief, Foreman, or Supervisor for review, approval, and notification to authorized employee. Communicate to the Chief, Assistant Chief, Foreman, or Supervisor and EHSO the need for Onthe-Job Training to retrain authorized and affected employees (if applicable). Lockout Procedures audits include a review, between the inspector and each authorized employee, of that employee's responsibilities under the energy control procedure being inspected. Annual procedure audits are to be filed by the Environmental Health and Safety Office. 14

15 Recordkeeping Recordkeeping shall be performed by individual departments that conduct or have responsibility for oversight of LOTO. The following records are to be kept: Records to be Filed Retention Department Departmental Authorized Employee list Equipment Specific Lockout Tagout Procedures Current Active Authorized Employees Length of Equipment operation Individual and EHSO Lockout Tagout Audit Forms 3 years EHSO Department Individual Dept. responsible for equipment and EHSO will keep the master electronic file of each procedure Formal classroom training for Authorized, Affected, and Other employees Length of employee s employment plus 3 years EHSO Program Enforcement Failure to follow the UIC Lockout/Tagout program may result in life threatening or serious injury situations. Failure to lockout or tagout or otherwise not follow the Lockout/Tagout procedures will result in disciplinary action up to and including termination. References 29 CFR OSHA Control of Hazardous Energy Electrical Safe Work Practices Program Review The Control of Hazardous Energy (Lockout/Tagout) Program will be periodically reviewed and updated by the UIC Environmental Safety and Health department to reflect UIC process and procedure changes and external regulatory changes that impact its content. Changes will be indicated upon program revisions made. Changes will be communicated to affected UIC departments. 15
