Lockout/Tagout Procedure

Transcription

1 I. BACKGROUND/PURPOSE Lockout/Tagout Procedure OSHA (29 CFR ) Locking and tagging out equipment safeguards employees from being injured by unexpected release of stored energy or re-energizing of equipment during installation, adjustment, service, or maintenance of powered machines. This document describes the acceptable procedures on the University of Saint Francis campus for locking and tagging out equipment and is intended to help campus departments comply with applicable OSHA regulations 29 CFR II. DEFINITIONS Affected person: Any person whose job requires that he/she operates or uses a piece of equipment on which maintenance or service is being performed; or whose job requires that he/she works in the area of the equipment; or any person in close proximity to the equipment. Authorized worker: A worker who has demonstrated by experience or training that he/she understands the operation of the equipment and can safely service or repair the equipment. Energy Sources: Any source of electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other energy High pressure steam: Steam under pressure of more than 20 pounds per square inch. Lock: A keyed padlock with two keys: one in the possession of an authorized worker and the other retained by the head of the department. The lock is to be identified for use by a specific worker. Primary voltage: Voltages of 7200 volts A. C. or more to ground. Tag: A durable, securely attached, non-reusable printed or handwritten document that clearly indicates a device is not to be operated, who tagged out the equipment, and the time and date the equipment was tagged out. The tag should be made of appropriate material for the environment in which it is used. III. PROCEDURE All employees are required to comply with the restrictions imposed during lockout/tagout. No employee is permitted to attempt to restart or re-energize equipment that is locked/tagged out. Only authorized employees are permitted to conduct the lock-out/tag-out procedure. Contractors are required to adhere to these procedures for work on University-owned equipment. Failure to comply with lockout/tagout procedures creates an unsafe work environment, will be reported to department head or upper administration and is punishable up to termination. Lockout/Tagout Policy 1

2 Work on or around powered equipment is covered by this procedure if: 1. A person may contact electrified or otherwise energized components while performing the work. 2. A person is required to remove or bypass any guard, interlock, or other safety device (including equipment covers) to perform the work. 3. A person is required to place any part of his/her body into an area on the machinery or a piece of equipment where work is performed during the equipment's operation. Examples of activities covered by these procedures include but are not limited to: when a circuit is de-energized for electrical work. when repairing high voltage electrical service equipment. when changing filters or otherwise maintaining walk-in air handlers. when changing the fan motor on an air handling unit. when performing service work in the elevator shafts. when performing service work on chillers and cooling towers. when performing service work on battery back-up systems, generators or anywhere there. are two separate power sources. when working on steam lines while boilers are on line. when performing service work on a conveyer. when unjamming a printing press. when performing service work on kitchen equipment that use live steam. when performing service work on the hydraulic trash compactor. when adjusting the internal electronics of a piece of equipment. when repairing tools such as the band saw, table saw etc. if during that time the plug is not under the control of the person doing the work. This procedure does not apply to: 1. Minor tool changes and adjustments and other minor service activities that take place during normal operations if they are routine, repetitive, and integral to the use of the equipment for production, provided that the work is performed using alternate measures that provide effective protection. (An example of this would be changing a drill bit on a drill press.) 2. Work on electrical equipment that is connected by a cord and plug where the hazard of the equipment being accidentally turned on or releasing stored energy is eliminated by unplugging the equipment. The person working on the equipment must have exclusive control over the plug. 3. Work on equipment that cannot be shut down, provided that: a. department management demonstrates that continuity of service is essential; b. shutdown of the system is impractical; and c. special equipment is provided or special protective procedures are used that will provide effective protection for personnel. (Examples include work on electrical circuits supplying network computer equipment or work on utility lines. Responsibilities 1. Risk and Safety Management Committee ensures: Lockout/Tagout Policy 2

3 authorized and affected employees have received training; periodic (at least annual) inspections have been conducted on the policy, procedures and employee knowledge; lock-out/tag-out equipment is in good condition; handle violations to the procedure. 2. Department Director/Chairperson shall: implement this policy in the department; provide lockout/tagout training; provide funds for and make sure proper lockout/tagout equipment is provided to supervisors; report procedure violations to the Risk and Safety Management Committee. 3. Supervisors (or Director) shall: ensure the worker assigned is authorized for lockout/tagout procedures; issue the necessary lockout/tagout equipment to the worker; confirm the worker applies lockout/tagout equipment properly; report procedure violations to the Director periodically (at least annually) review the procedures, equipment and employee knowledge for inadequacies; bring inadequacies to the attention of the Director with recommendations for changes. 4. Authorized Worker will: use lockout/tagout procedures and equipment as outlined in this document; inform the supervisor of the lack of, loss or damage to lockout/tagout equipment; report procedure violations to the Supervisor. Authorization to Work on Energized Equipment Authorized personnel may oversee or perform work on energized equipment such as described in this document only if they are qualified for the work. Supervisors are to determine who is qualified to work on energized equipment. Only the Supervisor may authorize work on energized equipment. Lockout Procedure 1. Notify all affected persons of equipment that will be off and locked out. 2. Identify type and magnitude of all energy sources for the equipment. 3. Shut off or otherwise de-energized all energy sources of the equipment, including all valves, switches, breakers, or other controls that supplies energy to the equipment. In the case of mechanical energy, a block may be used to stop the release of stored energy. 4. Place a lock on each energy source disconnect or energy release block, affixed so that reenergizing is not possible. a. The lock is to be placed directly on the equipment if provided with an integral lockout device. Lockout/Tagout Policy 3

4 b. If there is no integral lockout device on the equipment, securely attach an independently manufactured lockout device on the equipment and then place the lock on the lockout device. c. If none of the above is possible, use the tagout procedure. 5. A tag to be secured to the lock indicating that the equipment is not to be energized and who owns the lock. 6. Release stored or residual energy. 7. Verify that the lockout prevents the release of energy. Tagout Procedure 1. This procedure is to be used only if it is not possible to use the lockout procedure. 2. Notify all affected persons of equipment that will be off and tagged out. 3. Identify type and magnitude of all energy sources for the equipment. 4. Shut off or otherwise de-energized all energy sources of the equipment, including all valves, switches, breakers, or other controls that supplies energy to the equipment. In the case of mechanical energy, a block may be used to stop the release of stored energy. 5. Securely place a tag on each energy source disconnect or energy release block. The tag must be legible, understandable, durable and securely attached. Removal of a lockout or tagout 1. Lockout/tagout equipment must be removed by the worker who placed it. 2. Before the removal of a lockout/tagout the following must be completed: a. Removal of all non-essential items. b. Check to see that all workers and bystanders are located in a safe position. c. Inform all affected personnel. 3. If the worker who applied the lockout/tagout is not present, and his supervisor deems it necessary to energize the equipment, the following must be done by the supervisor: a. Verify that the worker is not on campus. b. Make all reasonable effort to contact the worker. c. Determine the purpose of the lockout/tagout, and whether it is safe to operate the equipment in its current condition. d. Remove all non-essential items. e. Inform all affected personnel. f. Check to see that all affected persons are located in a safe position g. Inform the worker of the lockout/tagout removal before the worker returns to work. Protecting More Than One Worker When more than one person works on the same equipment, multiple lockout devices must be used. Each authorized worker must put his/her lock on the multiple lockout devices and remove it when he or she stops working on the equipment. Only when all locks are removed can the equipment be re-energized. Equipment Requiring Particular Procedures IV. TRAINING Lockout/Tagout Policy 4

5 Authorized workers shall receive training on recognizing energy source types and magnitudes at USF, methods for energy isolation and control and use of the USF lock-out/tag-out procedures and the limitations of tags compared to locks. Affected persons shall be informed of the procedures and understand they are prohibited from attempting to restart a locked or tagged out machine. Authorized and affected employees will be retrained when a change in job assignment or periodic review necessitates. Records of lockout/tagout training and retraining are to be kept by the department head. These records should include the date, the name of the worker, and the name of the instructor. V. OVERSIGHT OF THIRD PARTY SERVICE PROVIDERS When an outside contractor will be engaged in activities covered by the lockout/tagout requirements, the contractor and the University must inform each other of their respective lockout/tagout procedures. The University employees must comply with the restrictions of the outside employer s lockout/tagout program. It is the responsibility of the University to ensure that the activities of all service providers are conducted in accordance with reasonable policies and procedures designed to detect, prevent, and mitigate the risk of injury or death from stored energy. Before the University may engage a service provider to perform an activity in connection with one or more of the University s covered accounts, the University must ensure the service provider performs its activities in accordance with reasonable policies and procedures.
