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.
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
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.
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.
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 ACTIVITYCOLOR, 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 -312017) • Authorized Employees Use Standard Procedures or Equipment Specific Procedures • INITIATE ACTIONS TO IDENTIFY AND RESOLVE DEFICIENCIES IN THE LOCKOUT/TAGOUT BUDGET AND
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
