Energy Control (Lockout/Tagout)

OBJECTIVES: Upon completion of this topic you will be able to: Describe general procedures for ISU Hazardous Energy Control – Lock-out/tag-out Program. Identify the various hardware for lockout/tagout procedures. Identify training requirements for lockout/tagout. Define activity responsibilities for the Hazardous Energy Control Program.

ENERGY CONTROL PROGRAM CONTROL OF HAZARDOUS ENERGY DURING SERVICING AND MAINTENANCE OF MACHINERY AND EQUIPMENT

ENERGY CONTROL PROGRAM REQUIREMENTS APPLY WHEN THE UNEXPECTED ENERGIZATION COULD CAUSE INJURY TO PERSONNEL AND/OR PROPERTY

EXEMPTED FROM REQUIREMENTS EQUIPMENT UNDER EXCLUSIVE CONTROL OF ELECTRICAL UTILIZATION INSTALLATIONS FOR THE PURPOSE OF POWER GENERATION, TRANSMISSION AND DISTRIBUTION

EXEMPTED FROM REQUIREMENTS Work on cord and plug connected electrical equipment

ISUStandard Procedure LOTO (1) Review the type and magnitude of the energy that the machine or equipment utilizes. Determine related hazards. If the equipment has more than one energy source or stored energy, a copy of the specific written lockout/tagout procedure can be obtained from your supervisor or found in Appendix D. Note: the review may also include discussions with the equipment operator. (2) Notify affected employees that the equipment or machine will be locked or tagged out and the reason for the lockout or tagout. Determine if you can use the standard procedure or if an equipment specific procedure is needed. (this does not include those do not make personal contact with the equipment, but are present to support the effort). It is important to inform those that operate the equipment or otherwise are affected or in proximity to the equipment.

ISU Standard Procedure - Continued (3) If the equipment or machine is currently operating, shut it down by utilizing standard shut down procedures. (4) Identify the energy isolating device to isolate the equipment from its energy source. (5) Each authorized employee performing contact work on the equipment should verify that the equipment has been shut down The lock/tag must include the employee's name, department and phone number. No employee shall begin contact work on the equipment without installing their personal lock nor should any employee place a lock for another employee. No lock should be used without a tag and any mechanism that can be locked must be locked (a tag and tie is not acceptable, except in a locked utility space that the locked access door indicates authorized access only, and key control is limited to authorized employees). Lathe equipment or machines which cannot accept a lock, a specific tagout procedure should be followed (see Appendix D).

ISU Standard Procedure - Continued (6) Each authorized employee who will perform contact work on the job, shall place their lock on the energy isolating device. Each authorized employee performing contact work on the equipment shall confirm that under normal operating conditions the equipment will not start or release stored energy. (7) All electrical and other power connections shall be treated as energized and employees shall wear appropriate PPE until they are tested. Once this is completed, repair work, service or maintenance can commence. Each authorized employee who will perform contact work on the job, shall place their lock on the energy isolating device. Each authorized employee performing contact work on the equipment shall confirm that under normal operating conditions the equipment will not start or release stored energy. All energy (electrical other power) connections shall be treated as energized and employees shall wear appropriate PPE until they are tested. Once this is completed, repair work, service or maintenance can start.

Procedures Involving More than One Person: If during the proceeding procedure, more than one person is required to lockout the equipment, each person shall place their own assigned lockout device on the energy isolating device. If the equipment cannot accept multiple locks, a hasp must be used. An alternative measure would be to use one lock and a lockout box. A single lock is placed on the machine and the key is placed in a lockout box or cabinet with multiple locks

GENERAL PROCEDURES LOCKOUT/TAGOUT AFFIXED TO EACH ENERGY ISOLATING DEVICE AUTHORIZED EMPLOYEE SHALL HAVE KNOWLEDGE OF THE TYPE AND MAGNITUDE OF ENERGY INVOLVED

Lock-out/Tag-out Completion. Once the contact work on the locked-out energy source is completed, the tag remains on the equipment while the authorized user is verifying operations and the service, inspection or maintenance task is complete. If the work is complete the locks and tags are removed.

GENERAL PROCEDURES (cont.) TAGS ONLY REMOVED BY AUTHORIZED EMPLOYEE, NEVER BYPASS OR IGNORE

GENERAL PROCEDURES (cont.) SHOULD INCLUDE WORDS LIKE “DO NOT OPEN”, “DO NOT CLOSE”, “DO NOT ENERGIZE”, OR “DO NOT OPERATE”

TAGOUT DEVICES ATTACHMENT NON-REUSABLE, NON-RELEASABLE, WITH A MINIMUM UNLOCKING STRENGTH OF NO LESS THAN 50 POUNDS

Tag LOCKOUT/TAGOUT IDENTIFY EMPLOYEE, SHOP OR CODE, TELEPHONE NUMBER, SUPERVISOR, DATE APPLIED, MACHINE EQUIPMENT OR SYSTEM DEENERGIZED

HARDWARE LOCKOUT/TAGOUT DEVICES SINGULARLY IDENTIFIED CAPABLE OF WITHSTANDING THE ENVIRONMENT STANDARDIZED WITHIN THE ACTIVITY- COLOR, SIZE, SHAPE LOCKOUT DEVICES SUBSTANTIAL ENOUGH TO PREVENT REMOVAL NO TWO LOCKS SHALL BE KEYED THE SAME, NO MORE THAN -- TWO KEYS FOR A LOCK

OTHER ISOLATING MEASURES REMOVAL OF FUSE OR CIRCUIT BREAKER BLOCKING OF A CONTROLLING DEVICE REMOVAL OF A VALVE HANDLE

TRAINING ACTIVITY SHALL PROVIDE TRAINING TRAINING MUST BE SPECIFIC TO THE ACTIVITY LIMITATIONS OF TAGOUT SHOULD BE STRESSED; THAT THEY ARE ESSENTIALLY WARNING DEVICES AND DO NOT PROVIDE PHYSICAL RESTRAINT

RESPONSIBILITIES DEVELOP AND IMPLEMENT WRITTEN PLANS AND PROCEDURES (ISU 3-31-2017) Authorized Employees Use Standard Procedures or Equipment Specific Procedures INITIATE ACTIONS TO IDENTIFY AND RESOLVE DEFICIENCIES IN THE LOCKOUT/TAGOUT BUDGET AND ALLOCATION OF RESOURCES

RESPONSIBILITIES ENSURE PROCEDURES ARE REVISED AND UPDATED ENSURE A CURRENT ROSTER OF TRAINED AND QUALIFIED EMPLOYEES IS MAINTAINED

PERIODIC REVIEW ACTIVITY SHALL CONDUCT PERIODIC REVIEW AT LEAST ANNUALLY WHEN ACCIDENT OR INCIDENT OCCURS
