[Company Name/Location]
I. OBJECTIVE
The objective of this procedure is to establish a means of positive control to prevent the accidental starting or activating of machinery or systems while they are being repaired, cleaned and/or serviced. This program serves to:
A. Establish a safe and positive means of shutting down machinery, equipment and systems.
B. Prohibit unauthorized personnel or remote control systems from starting machinery or equipment while it is being serviced.
C. Provide a secondary control system (tagout) when it is impossible to positively lockout the machinery or equipment.
D. Establish responsibility for implementing and controlling lockout/tagout procedures.
E. Ensure that only approved locks, standardized tags and fastening devices provided by the company will be utilized in the lockout/tagout procedures.
Although the procedures described in the Program are intended to facilitate compliance with applicable governmental regulations, they are not intended to supersede the requirements of such regulations.
II. ASSIGNMENT OF RESPONSIBILITY
A. [Responsible Person] will be responsible for implementing the lockout/tagout program.
B. [Responsible Person] is responsible for enforcing the program and insuring compliance with the procedures in their departments.
C. [Responsible Person] is responsible for monitoring the compliance of this procedure and will conduct the annual inspection and certification of the authorized employees.
D. [Responsible Person] is responsible for training all employees affected by this program.
E. Authorized employees (those listed in Appendix A) are responsible for following established lockout/tagout procedures. An authorized employee is defined as a person who locks out or tags out machines or equipment in order to perform servicing or maintenance on that machine or equipment.
F. Affected employees (other employees in the facility) are responsible for insuring they do not attempt to restart or re-energize machines or equipment that are locked out or tagged out. An affected employee is defined as a person whose job requires him/her to operate or use a machine or equipment on which servicing or maintenance is being performed under lockout or tagout, or whose job requires him/her to work in an area in which such servicing or maintenance is being performed. An affected employee becomes an authorized employee when that employee's duties include performing servicing or maintenance covered by the Control of Hazardous Energy (lockout/tagout) program.
III. PROCEDURE
The ensuing items are to be followed to ensure both compliance with the Control of Hazardous Energy Standard and the safety of our employees.
A. Preparation for Lockout or Tagout
Employees who are required to utilize the lockout/tagout procedure (see Appendix A) must be knowledgeable of the different energy sources and the proper sequence of shutting off or disconnecting energy means. The four primary types of energy sources are:
1. electrical
2. hydraulic or pneumatic
3. fluids and gases
4. mechanical (including gravity)
More than one energy source may be utilized on some equipment and the proper procedure must be followed in order to identify energy sources and lockout/tagout accordingly. In some instances, there will be other sources of stored energy that must be controlled. Examples include radioactive materials in fluoroscopes and explosive devices such as airbags systems. See Appendix F for specific procedure format.
1. Electrical
a. Shut off power at machine and disconnect.
b. Disconnecting means must be locked or tagged.
c. All controls must be positioned in their safest position.
d. Points to remember:
i. If a machine or piece of equipment contains capacitors, the capacitors must be drained of stored energy.
ii. Possible disconnecting means include the power cord, power panels (look for primary and secondary voltage), breakers, the operator's station, motor circuit, relays, limit switches, and electrical interlocks.
iii. Some equipment may have a motor isolating shut-off and a control isolating shut-off.
iv. If the electrical energy is disconnected by simply unplugging the power cord, the cord must be kept under the control of the authorized employee or the plug end of the cord must be locked out or tagged out.
2. Hydraulic/Pneumatic
a. Shut off all energy sources (pumps and compressors). If the pumps and compressors supply energy to more than one piece of equipment, lockout or tagout the valve supplying energy to the piece of equipment being serviced.
b. Stored pressure from hydraulic/pneumatic lines shall be drained / bled when release of stored energy could cause injury to employees.
c. Make sure controls are returned to their safest position (off, stop, standby, inch, jog, etc.).
3. Fluids and Gases
a. Identify the type of fluid or gas and the necessary personal protective equipment.
b. Close valves to prevent flow, and lockout/tagout.
c. Determine the isolating device, then close and lockout/tagout.
d. Drain and bleed lines to zero energy state.
e. Some systems may have electrically controlled valves. If so, they must be shut off and locked/tagged out. Pay particular attention to the design to the valves to determine if they are normally open or normally closed when power is removed and take action accordingly to control stored energy.
f. Check for zero energy state at the equipment.
4. Mechanical Energy
a. Mechanical energy includes gravity activation, energy stored in springs, inertia in moving or rotating parts, etc.
b. Block or safety chain or otherwise immobilize parts that are designed to move or may move or shift if unsecured during work.
c. Lockout or tagout safety device.
d. Shut off, lockout or tagout electrical system.
e. Return controls to safest position.
B. Confirmation of Energy Control
1. When all energy sources have been controlled, all employees should move to a safe zone and one employee shall press the start button or activate similar control mechanisms to see that all systems are correctly locked out. Check that all energy sources are at their zero energy state.
C. Release from Lockout/Tagout
1. Inspection: Make certain the work is completed and inventory the tools and equipment that were used.
2. Clean-up: Remove all towels, rags, work-aids, etc.
3. Replace guards: Replace all guards possible. Sometimes a particular guard may have to be left off until the start sequence is over due to possible adjustments. However, all other guards should be put back into place.
4. Check controls: All controls should be in their safest position.
5. The work area shall be checked to ensure that all employees have been safely positioned or removed and notified that the lockout/tagout devices are being removed.
6. Remove locks/tags. Remove only your lock or tag.
D. Service or Maintenance Involving More than One Person
When servicing and/or maintenance is performed by more than one person, each authorized employee shall place his own lock or tag on the energy isolating source. This shall be done by utilizing a multiple lock scissors clamp if the equipment is capable of being locked out. If the equipment cannot be locked out, then each authorized employee must place his tag on the equipment.
E. Emergency Removal of an Authorized Employee’s Lockout/Tagout by the Company
In some instances an authorized employee may not be available to remove the lock or tag they applied to a piece of equipment. Perhaps illnesses or another urgent matter has required the employee’s sudden departure from the facility and prevented them from removing the lock or tag. In this case [Responsible Person] is the only employee authorized to remove the lock or tag. The [Responsible Person] will take and document the following actions before removing the lock or tag:
1. [Responsible Person] will verify that the authorized employee who applied the device is not in the facility.
2. [Responsible Person] will attempt to contact the authorized employee who applied the device by telephone to confirm the absence and notify the authorized employee that his/her device will be removed.
3. [Responsible Person] will make reasonable efforts to advise the employee upon their return to the facility that his/her device has been removed. This includes requiring all other authorized workers on the job to notify the absence employee of the removal and request that he/she confirms with the [Responsible Person].
4. [Responsible Person] will ensure and document that the authorized employee has this knowledge before he/she resumes work at the facility.
F. Shift or Personnel Changes
The continuity of lockout or tagout protection will be ensured at all times. All authorized and all affected employees must be informed when any lockout or tagout activity extends beyond the end of a shift or when there are other changes in personnel. In each instance where there is the departure or arrival of an employee or contractor to the job under lockout / tagout, the [Responsible Person] will gather all departing, all arriving and all remaining employees and contractors, both authorized and affected, and ensure:
1. that all locks or tags are removed by departing employees or contractors before work is resumed.
2. that arriving employees and contractors add their locks or tags before work is resumed.
3. that all employees and contractors, both authorized and affected, are informed of the changes in personnel before work is resumed.
4. the changes in personnel and notifications are documented.
G. Procedures for Outside Personnel/Contractors
Outside personnel or contractors shall be advised that the company has and enforces the use of lockout/tagout procedures. They will be informed of the use of locks and tags and notified about the prohibition of attempts to restart or re-energize machines or equipment that are locked out or tagged out.
The company will obtain information from the outside personnel or contractor about their lockout/tagout procedures and warn affected employees of this information.
The outside personnel or contractor will be required to sign a certification form (see Appendix E). If outside personnel or contractor has previously signed a certification that is on file, additional signed certification is not necessary.
IV. TRAINING
A. Authorized Employee
Each authorized employee who is required to perform a lockout/tagout procedure will be trained in the recognition of applicable hazardous energy sources, type and magnitude of energy available in the work place, and the methods and means necessary for energy isolation and control.
B. Affected Employee
Each affected employee (all employees other than authorized employees utilizing the lockout/tagout procedure) shall be instructed in the purpose and use of the lockout/tagout procedure, and the prohibition of attempts to restart or re-energize machines or equipment that are locked out or tagged out.
C. Training will be completed and certifications issued to all authorized and all affected employees when any of the following occur:
1. Before initial operation, maintenance and service procedures begin.
2. When deviations from written procedures are identified or suspected.
3. When there is a change in job assignment.
4. When there is a change in a energy control procedure, or
5. When there is a change in the machinery, equipment, process or tools covered by the energy control process.
D. Training certifications will be retained in accordance with the Facility Training Plan. Training will be certified using:
1. Appendix B (Authorized Personnel) or
2. Appendix C (Affected Personnel).
E. Periodic Audits
A periodic audit will be conducted at least annually of each authorized employee under the lockout/tagout procedure. This audit shall be performed by [Responsible Person]. If [Responsible Person] is also using the energy control procedure being inspected, then the audit shall be performed by another authorized party.
The audit will include a review between [Responsible Person] and each authorized employee under the energy control (lockout/tagout) procedure. The audit will include observation of each and every step of the energy control procedure being audited while the employee performs all the duties required by the energy control (lockout/tagout) procedures.
When the [Responsible Person] finds the authorized employee has completed activity in compliance with the entire energy control (lockout/tagout) procedures, he shall certify in writing that the audit has been performed. The written certification (Appendix D) shall be retained in the individual's personnel file.
If at any point during the audit the [Responsible Person] determines the authorized employee is not compliant with the energy control (lockout/tagout) procedures, he shall stop the authorized employee and together they shall review the perceived deficiencies. Before work is allowed to continue, all perceived deficiencies will be resolved:
1. by mutually agreeable interpretation and revision of the work methods if necessary,
2. cessation of the audit and retraining of the employee if [Responsible Person] deems it necessary, and
3. cessation of the audit and written revisions made to the energy control (lockout/tagout) procedures to correct identified errors in the procedures followed by retraining of all authorized and affected employees.
