This procedure helps to establish general requirements for controlling hazardous energy during service or maintenance of machines or equipment, in accordance with the requirements of OSHA 1910.147.This program assists with practices and procedures necessary to disable machinery and prevent the release of potentially hazardous energy while maintenance or servicing activities are performed at Company2.
Program Scope
Lockout/Tagout will be used when employees are involved in constructing, installing, setting up, adjusting, inspecting, modifying and maintaining or servicing machines or equipment. These activities include lubricating, cleaning or unjamming machines, and making adjustments or changes to tools, guards or safety devices where the employees may be exposed to hazardous energy.
The standard applies to all sources of energy, including, but not limited to:
- mechanical
- electrical
- hydraulic
- pneumatic
- chemical
- radiation
- thermal energy
- kinetic
Authorized employees subject to the requirements of this program are to be trained on their duties within it, including:
- Recognizing applicable hazardous energy sources
- Type and magnitude of the energy available in the workplace
- Methods and means necessary for energy isolation, control and verification
- Limitation of energy control devices
- Procedure for complying with Company3‘s lockout/tagout procedure
Affected employees are subject to the requirements of this program and are to be trained on their duties within it, including:
- Understanding the lockout/tagout procedure
- Recognizing lockout/tagout devices and identifying that equipment is out of operation
- Purpose and use of energy control procedures
- To never re-energize or start equipment that is actively controlled by lockout or tagout procedures
All employees are required to comply with the restrictions and limitations imposed upon them during lockout. Authorized employees are required to perform the lockout in accordance with this procedure.All employees, upon observing a machine or piece of equipment that is locked out for servicing or maintenance shall not attempt to start, energize or use that machine or equipment.
Administrative Responsibilities
Implement1 will be the one ultimately responsible for implementing these procedures. The procedures will clearly outline the scope, purpose, authorization, rules and techniques to be utilized for controlling hazardous energy and the means to enforce compliance. This includes but is 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 (manufacturer's specification will be followed whenever possible)
- Specific procedural steps for placing, removing and transferring lockout/tagout devices, and the person(s) responsible for them
- Specific requirements for testing a machine or equipment to determine and verify the effectiveness of lockout/tagout devices and other energy control measures.
Hardware and Materials
Lockout devices must be identified as such, and not used for any other purpose. All locks used for energy isolation will be kept in a designated box at identified locations (see Appendix I). Each specific department shall be responsible for distributing the locks and securing the keys.
Both lockout and tagout devices must be capable of withstanding environmental conditions in the workplace (locks should not rust or tags deteriorate). All tagout devices will be standard with a "DO NOT OPERATE" warning. All lockout/tagout devices will be uniform in color, shape, design or size to maintain integrity of the program.
Each authorized employee will receive one lock and one key. Individual employee locks shall be permanently marked to identify the intended user. The second key will be destroyed or maintained in a locked supervisory key case in the employee's department.
Periodic Inspection
A periodic inspection of the energy control procedure(s) shall be conducted at least annually to ensure that the procedure and the requirements of the program are being followed.The periodic inspection shall be performed by InspectProcedures and not by the one(s) utilizing the energy control procedure being inspected.Any deviations or inadequacies identified during the inspection shall be corrected. Documentthat the inspection has been performed.
Sequence of Lockout/Tagout
- Preparation for Shut Down
- Energy Source Identification: Before an authorized or affected employee turns off a machine or equipment, the authorized employee must have knowledge of the type and magnitude of the energy sources, the hazards of the energy to be controlled, and the method or means to control the energy.
- Notification: Notify all affected employees that equipment or machines will be shut down and the energy isolated by the .
- Machine or Equipment Shut Down
The machine or equipment will be turned off or shut down using the specific procedures established for the machine or equipment. Develop a step-by-step list to perform a systematic and uniform shut down to avoid any additional or increased hazard(s) to employees as a result of disabling equipment.
The authorized employee will refer to our procedure to identify the type and magnitude of the energy that the machine or equipment utilizes. This employee should understand the energy hazards and the methods to control the energy.
- Lockout Device Application
Lockout/tagout devices must be affixed to each energy-isolating device by authorized employees and must be affixed in a manner that will hold the energy isolating devices in a "safe" or "off" position. Lock and tag the energy-isolating device(s) with assigned individual lock(s), couplings, valve covers, etc., as per machine-specific procedure. Lockout/tagout devices shall be designed and installed to prevent inadvertent or accidental removal.
Group Lockout/Tagout
When servicing and/or maintenance is performed by a crew, department or other group, they will use our procedure which affords employees a level of protection equivalent to that provided by implementing a personal lockout or tagout device. Group lockout or tagout devices will isolate the energy sources with a unique operations lock, with all authorized employees then securing that key in a group lockout box or similar device.
- Stored Energy
After applying the lockout/tagout devices to energy isolating devices, all potentially hazardous stored or residual energy will be relieved, disconnected, restrained and otherwise rendered safe. Residual energy (such as that in capacitors, springs, upper dies, rotating flywheels, hydraulic systems, and air, gas, steam, or water pressure, etc.) must be dissipated or restrained by methods such as grounding, repositioning, blocking, bleeding, dissipation, etc.
If there is a possibility of reaccumulation of stored energy to a hazardous level, verification of isolation must be continued until the servicing or maintenance is complete, or until the possibility of such accumulation no longer exists.
- Verification of Isolation
Prior to starting work on machines or equipment that have been locked/tagged, the authorized employee will verify that the machine or equipment has been isolated and de-energized. This process must include at least:
- Assuring that all materials, equipment, tools and persons are clear of hazardous moving parts
- Verifying that all potential residual energy sources have been bled, withheld, or are in a “zero energy state”
- Verifying that the electrical current flow in the system is isolated from the main power source, by using a multimeter
- Viewing all gauges to verify zero pressure on pipeways and lines
- Attaching a unique lock and tag device to the machine or equipment for each crew member
- Verifying “zero energy state” by attempting startup. (Finish by activating the “stop” button, and be certain that all affected persons are clear of the machine)
- If equipment can be started remotely, verifying that all remote controls are identified, locked out and tested
- Lockout or Tagout Release
Before removing lockout/tagout devices and restoring energy to the machine or equipment, the following procedures will be taken by the authorized employee(s):
- Machine or equipment: Inspect the work area to ensure that nonessential items have been removed and that the machine or equipment components are functional. Also, verify that any machine safeguards and devices that were removed have been properly reinstalled.
- Employees: The work area will be checked to ensure that all employees are safely positioned or removed. After lockout/tagout devices are removed and before the machine or equipment is started, affected employees will be notified that the lockout or tagout device(s) have been removed.
- Removing Lockout/Tagout Devices
Each lockout/tagout device will be removed from each energy-isolating device by the employee who applied the device. In the event the authorized employee who applied the lockout/tagout device is not available to remove it, that device may be removed under the direction of the LOTORemoval.
Testing Machines, Equipment or Components
When the lockout/tagout device must be temporarily removed and the machine re-energized, test or position the machine by:
- Clearing away tools and materials from the equipment or machine
- Removing employees from the machine or equipment area
- Removing the lockout/tagout devices, as specified, as part of the individual machine procedures
- Energizing the equipment or machine and proceeding with testing or positioning
- De-energizing all systems and reapplying energy control devices and features in accordance with machine procedures, and continuing the servicing and/or maintenance
- Caution: Be certain to return operating control(s) to neutral or "off" position after verifying the equipment has been isolated
NonCompany Personnel (Contractors, Etc.)
When outside servicing personnel are engaged in activities covered by the scope and application of this instruction, Contractors1 and the outside employer will inform each other of their respective lockout/tagout procedures.
- The Contractors2 will ensure that our employees understand and comply with the restrictions and prohibitions of the outside employer's energy control program.
- A copy of the contractor’s plan will be compared with our plan. The contracting company official will be required to sign an agreement stating that they will follow our policy which is unique to our equipment and operations. This agreement will be maintained with the contractor file and retained after job completion.
- The Contractors3 will inspect the work of the contractor to assure that the agreement is being upheld. Any problem or lack of follow through with the lockout procedure, as identified in the agreement, will be grounds for work to be temporarily stopped and reevaluated. Disregard for the policy and procedure in this plan will be grounds for actions as stipulated in the contract.
