LOCK-OUT/TAG-OUT (LO/TO) SAFETY PROGRAM

Transcription

1 LOCK-OUT/TAG-OUT (LO/TO) SAFETY PROGRAM REGULATORY STANDARD: OSHA - 29 CFR BASIS: Approximately three million workers in the United States face risks from uncontrolled energy when servicing machinery daily. OSHA estimates that approximately 120 fatalities and approximately 28,000 serious and 32,000 minor injuries each could be prevented if proper lock-out/tag-out procedures at job sites are initiated. The OSHA Standard establishes requirements to ensure that the hazards of uncontrolled energy in the workplace are evaluated, safety procedures implemented, and that the proper hazard information is transmitted to all affected workers. GENERAL: The company will ensure that all machinery meeting the criteria for lock-out/tag-out within our facility is evaluated and that LO/TO information, safety training programs, and procedures are implemented. 1.

2 Lock-Out/Tag-Out (LO/TO) Safety Program 1. Purpose. This program covers working on or around equipment where employees may be exposed to the unexpected energization, motion or start-up of machines or equipment. This program assists in compliance with 29CFR regulations for the control of hazardous energy. 2. Scope. This standard applies to all locations and covers the servicing and/or maintenance of machines and other equipment and processes. The standard does not apply to cord and plug connected electrical equipment that is under the control of the servicing mechanic, or hot tap (i.e. welding) operations. 3. Responsibilities. 3.1 Management: Evaluate the potential hazards of specific equipment Establish a written program Establish written LO/TO procedures for each individual or group of similar machines in place Communicate with contractors regarding the company s Lock-Out/Tag-Out Program and exposures Train employees (3 levels: Authorized, Affected and Other) Verify Lock/Tag application process Account for new equipment and processes Establish group lockout process as needed Implement Lock Removal for Absent Employee procedures Perform annual and periodic inspections, as required Account for shift and personnel changes, as needed or required 3.2 Safety Officer (as needed or required): Assist in writing machine specific procedures Evaluate the potential hazards of specific equipment, and assist in reducing those hazards Ensure that LO/TO locks and tags are used only for LO/TO purposes Lock-Out/Tag-Out Safety Program Page 2 of 12

3 4. Procedure Assure that new equipment (or changes to old equipment) has LO/TO capability 4.1 Written Program: This document serves as the written lock-out/tag-out program for the company. Before performing service or maintenance on equipment or machinery where energy or motion could release and cause injury, the energy sources must be isolated and locked out. 4.2 Written Procedures: Up-to-date written procedures are in place and followed for the isolation of an energy source (including locking, blocking and tagging). Procedures must be written for both routine and non-routine service and maintenance work, and including production work such as set-up, cleaning and un-jamming. These procedures must include sufficient detail to provide each employee with control over all hazardous energy they may be exposed to (such as electrical, mechanical, gravitational, hydraulic, pneumatic, chemical, thermal, or other hazards). A template-form is included with this program to assist in writing the required procedures Informing contractors of company devices and procedures Informing employees about differences in the contractor s devices and procedures and about company procedures Assuring procedures are in place to maintain LO/TO requirements during shift changes or personnel changes to maintain the integrity and continuity of LO/TO requirements 4.3 Application of Locks and Tags or Other Energy Control Devices: The Six Steps of LO/TO Preparation for Shutdown the Authorized Employee must have knowledge of the type and magnitude of the energy, the hazards of the energy to be controlled and the methods and means to control the energy. This knowledge should include a review of the written procedure Machine or Equipment Shutdown Shutdown machine or equipment using the established written procedures (normal operating procedures) after notifying Affected Employees in the area of the shut-down Machine or Equipment Isolation - Locate and isolate all energy sources Hazardous Energy Control Device Application Apply or affix Lock and Tag (or other device) so that equipment is held in a safe or off position.

4 Stored Energy Relieve, disconnect or restrain all energy sources so that they are made safe Verification of Isolation The authorized employee will verify the isolation and de-energizing of the machine or equipment by trying to activate the machine Tags without Locks Tags will accompany LO/TO specific locks at all times, unless: Other Energy Control Devices If locks cannot be used, tags must be supplemented by other means to ensure an equivalent level of safety to that of a lock application (Example: removing a control switch, circuit breaker or valve handle) Where locks are not used, the supplemental means (and its written procedure) must be reviewed with each authorized and affected employee at least annually When equipment is being taken out of service (i.e. abandoned in place or no longer used), non-lo/to locks and tags will be used. The tag will contain the words "Out of Service" and an appropriate description Blocks, chains, wedges, adapter pins, self-locking fasteners may be used to block machines or equipment from unexpected energization. (For example: A block may be used to wedge open a mechanical power press during tool changes to prevent the machine from cycling) Release from LO/TO or Restoring Equipment to Service Check the work area to ensure that tools and other non-essential items have been removed and that the machine or equipment components are intact Check the area to ensure that employees have been safely moved away from the work area Verify that the machine controls are in neutral or off Remove the lock-out/tag-out device(s) Reenergize the machine or equipment. NOTE: the removal of some forms of blocking may require reenergizing of the machine before safe removal Notify area employees that the servicing or maintenance work is completed and the machine is ready for use.

5 4.4 Lock Removal for Absentee Employee Process: Each LO/TO device shall be removed from the energy isolating device by the employee who applied the device When the Authorized Employee who applied the LO/TO device is not available to removed it, the device may be removed under the direction of a single designated person at the company provided this designated person follow specific procedures. At a minimum, these include: Verification that the Authorized Employee who applied the device is not at the facility Efforts are made to contact the Authorized Employee to inform them that their LO/TO device has been removed There are methods followed to ensure the Authorized Employee knows their device was removed BEFORE they resume work The Safety Officer will either serve as the responsible person or management will designate an individual to serve in this capacity To assist in the consistent application of the absentee lock removal process, a form has been provided with this program. 4.5 Tag Application: Use only company approved LO/TO locks, tags, blocks and other devices Attach tags with nylon cable ties or an equivalent strength material Attach tags to the locks Tags will contain the following information: Name of equipment being secured Name of person securing Date of application (securing) How to contact person securing Reason for being secured (e.g. taken out of service, repair, etc.) A statement prohibiting removal or tampering with the lock or tag Lock-Out/Tag-Out Safety Program Page 5 of 12

6 4.5.2 Tags must include a statement such as Do Not Start, Do Not Open, Do Not Close, Do Not Energize or Do Not Operate. 4.6 New Equipment Design or Major Modifications to Existing Equipment: Machinery must be able to be locked out or made lockable when they are: Replaced or undergo major repairs Renovated or modified Purchased and installed New equipment installations must be capable of being locked out as an integral part of the machine (i.e. without the use of chains, etc.). 4.7 Group Lock-Outs: Group Lock outs will incorporate the use of a group lockout device. Devices may include a lockable container (like a strong-box) to hold the process lock keys and tagout records for large jobs and long duration work, or a multiple lock adapter (that will not release until all locks have been removed) for single machines that require more than one lock. These group devices are used as controls where there are complex situations involving many different people who all require the machine or process to be locked before they work on it One "Primary Authorized Person" will be assigned, and vested as responsible, for all the locks on the project and assuring continuity of energy control for the entire group A master locking device provides protection from the main energy source. The Primary Authorized Person is solely responsible for applying and removing this device Each authorized employee involved in the group lockout must affix a personal lockout or tag-out device to the machine, equipment or into group lockbox or onto the device when their work begins and remove it when their work is completed. 4.8 Shift/Personnel Change Procedures: Specific procedures to account for shift or personnel changes must ensure the continuity of LO/TO protection, and must include a provision for the transfer of devices between off-going and on-coming employees. This will minimize exposure to hazards from the unexpected energization or start-up of the machine or equipment or the release of stored energy. Lock-Out/Tag-Out Safety Program Page 6 of 12

7 4.9 Required Periodic Inspections: Inspect LO/TO procedures and actual lock-outs (at least annually) to assure they meet regulatory requirements. The inspection is led by a LO/TO Authorized employee who has been trained in that procedure. This person must be someone other than the one performing the lock-out. The inspections requirements include: Checking training records to verify people have been trained to the level necessary That the procedure document was reviewed within the last calendar year. Reviews must ensure the procedures are adequate, understandable and being followed A majority of the employees authorized to use that procedure participate in this review (group meeting reviews are acceptable) Field check the actual lock-out to assure the equipment is being locked out properly. The inspector and the person locking the equipment are required to participate, at a minimum Asking operators how they would lock/tag equipment, and verify by demonstration Note and correct any deficiencies Document/certify this assessment using the inspection certificate form provided with this program, or an equivalent record. Both the inspector and the person performing the LO/TO must sign the assessment certificate If the procedure is found lacking or deficient, it must be revised and all employees who would use that procedure must be retrained to the new procedure before servicing or maintaining that equipment Each procedure that is used for normal or routine lock-outs must be reviewed at least once per year. Non-routine lock-outs must have a procedure reviewed before the procedure is used, if it hasn t been used in the last calendar year. 5. Safety Information. 5.1 Specific Requirements for Electrical LO/TO with Greater than 50 volts to Ground: Only an Electrical Qualified Person (Electricians or persons specifically trained by an electrician) can operate the equipment or otherwise verify that the equipment can not be restarted. Lock-Out/Tag-Out Safety Program Page 7 of 12

8 5.1.2 Only an Electrical Qualified Person can use test equipment to test the circuit elements and electrical parts of the equipment, including exposure to back-feed or inadvertently induced voltage Only an Electrical Qualified Person can conduct tests and inspections to verify that the equipment can be safely re-energized Locks must be accompanied by tags Safe de-energizing and re-energizing procedures must be determined before service or maintenance is performed and approved in writing by an Electrical Qualified Person before the actual LO/TO is performed. 5.2 Records: Training records will be maintained. Training records include: The name of the employee trained The date of training As needed, information on the specific procedure to which the employee is trained (i.e. a non-routine task) Copies of training materials (i.e. the specific written procedure and signed inspection certificate) used for non-routine tasks must be kept. 6. Training and Information. 6.1 LO/TO Training General: Training will be provided to Authorized, Affected and Other employees, based on their exposure to LO/TO and Hazardous Energy Control procedures Training is required: upon initial assignment when changes in job responsibilities occur when new equipment is brought into an area when new processes that present new hazards are introduced when there are changes in the hazardous energy control procedures when deficiencies or deviations from established procedures are noted when an inspection or review reveals deficiencies Lock-Out/Tag-Out Safety Program Page 8 of 12

9 6.1.3 There are three specific levels of training required: Authorized employees will receive formal LO/TO training: The training should also be supplemented by localized application, procedure or equipment-specific instruction, which includes written procedures and hands-on instruction in LO/TO application The training should enable the recognition of applicable hazardous energy sources, the type and magnitude of the energy available in the workplace and the methods and means necessary for energy isolation and control Affected employees will receive a mid-range level of training to inform them of the purpose of the program, and their limitations and responsibilities under the program Training for Other employees can be verbally or by another method, and will inform employees about the procedure and program, about the prohibition relating to attempts to start machines or equipment that are locked out or tagged out, and in recognizing LO/TO devices and their purpose All levels of training should include information on who serves as the responsible person designated for the Lock Removal for Absent Employee process. 6.2 Tag-Out Only Systems: When tag-out only systems are used, all employees will be trained on the limitations of tags, including: Tags are warning devices only and do not provide physical restraint Tags may not be removed, except by the person who applied it Tags must be legible and understandable by all employees Tags must stand up to the conditions where they are applied (wet, cold, heat, etc.) Tags must be secure so they do not inadvertently fall off or get removed Tags may evoke a false sense of security and must not be used as a solesystem when locks or other devices can be applied.

10 6.3 Re-training: 7. Definitions Re-training is required for both Authorized and Affected Employees when: Employee lock-outs are performed incorrectly, reviews reveal deficiencies, or when there is reason to believe there are inadequacies in the employees knowledge of the energy control procedures A change in job assignment requires re-training Modifications to equipment occur which affects the LO/TO procedure or present a new hazard A procedure has been changed since the last time the employee performed LO/TO on that equipment or machinery. Authorized Employee - A person who locks-out or tags-out machines or equipment in order to perform servicing or maintenance (set up operators and tools changes). Affected Employee A person whose job requires them to work in an area or operate machinery or equipment on which servicing or maintenance is being performed under lock-out or tag-out. Capable of Being Locked-Out - An energy isolating device is capable of being locked out if it has a hasp or other means of attachment to which (or through which) a lock can be affixed, or it has a locking mechanism built into it. Other energy-isolating devices are "capable of being locked-out" if energy isolation can be achieved without the need to dismantle, rebuild or replace the isolating device, or permanently alter its capability. Energized Connected to an energy source or containing residual or stored energy LO/TO or Energy-Isolating Device - A mechanical device that physically prevents the transmission or release of energy, including, but not limited to the following: a manually-operated electrical circuit breaker, a disconnect switch, or a manually operated switch by which the conductors of a circuit can be disconnected from all ungrounded supply conductors and, in addition, where no pole can be operated independently a line valve a block any similar device used to block or isolate energy Push buttons, selector switches and other control-circuit type devices are not energyisolating devices. Energy source - Any source of mechanical, hydraulic, pneumatic, chemical, natural, thermal or other energy Other employees - All persons who are or may be in an area when LO/TO procedures or devices may be utilized. Lock-Out/Tag-Out Safety Program Page 10 of 12

11 Primary Authorized Person - An authorized person with the primary responsibility for group lockout applications. Qualified - Familiar with the construction and operation of the equipment and the hazards involved. Servicing and/or Maintenance Workplace activities such as constructing, installing, setting up, adjusting, inspecting, modifying and maintaining and/or servicing machines or equipment. These activities include lubrication, cleaning or un-jamming of machines or equipment and making adjustments or tool changes where the employee may be exposed to the unexpected energization or startup of the equipment, or a release of hazardous energy. 8. Summary. This program covers working on or around equipment where employees may be exposed to the unexpected energization, motion or start-up of machines or equipment. 8.1 Definitions: LO/TO or Energy-Isolating Device - a mechanical device (lock, tag, block, wedge, etc) that physically prevents the transmission or release of energy or equipment movement.
