O-7

(3) Tagout devices must warn against hazardous conditions if the machine or equipment is energized and must include a legend such as: DO NOT START, DO NOT OPEN, DO

NOT CLOSE, DO NOT ENERGIZE, DO NOT OPERATE.

5. General Lockout Procedure.

A. Lockout/Tagout (LOTO) Procedures. The authorized employee shall utilize LOTO procedures for the control of potentially hazardous energy when USIBWC personnel or contractors on USIBWC sites and projects are engaged in activities covered by this program. This section covers procedures for the general sequence of application, general sequence of restoring energy to a system, troubleshooting, group lockout, transfer of lockout responsibility and requirements for contractors.

Procedures developed for specific vehicles, equipment or machinery must be followed and may vary slightly from the general sequences described in this program.

B. General Sequence of Application.

(1) The authorized employee notifies all affected employees that the machine or equipment will be shut down and a lockout performed.

(2) The authorized employee reviews the procedure for the specific machine or equipment and shall be able to:

• Identify the type(s) and magnitude(s) of the energy that the machine or equipment uses.

• Understand the hazards of the energy.

• Know how and where to control the energy.

(3) The authorized employee shuts the machine down by its normal stopping procedure (stop button, open switch, close valve etc.)

(4) The authorized employee deactivates the energy isolating device so that the machine or equipment is isolated from the energy source(s). If there are multiple sources of energy involved, a lockout must be performed at all the applicable energy isolating devices and the following three steps must be initiated for all of the applicable energy isolating devices.

(5) The authorized employee puts an appropriate lockout device and tagout device on the respective energy isolating device(s) of the vehicle, equipment or machinery.

(6) The authorized employee dissipates residual or stored energy by methods such as grounding, repositioning, blocking, bleeding out etc. When there is a possibility of re-accumulation of stored energy to a hazardous level, verification of isolation shall be

O-8 continued until the energy control procedure is complete.

(7) The authorized employee verifies the effectiveness of the lockout. They ensure that the equipment is disconnected from the energy source(s) and that no personnel are exposed, then verify the isolation of the equipment by operating the push button or other normal control(s) or by testing to make certain that the equipment will not operate.

(8) The vehicle, equipment or machinery or confined space is now considered locked out. Consult the respective sections of this program for requirements involving group lockout, transfer of responsibility and troubleshooting under a lockout and restoring energy.

C. General Sequence for Restoring Equipment to Service. When the servicing or maintenance is completed and the machine is ready to return to normal production operations, the authorized employee shall perform the following steps:

(1) Checks with USIBWC supervisor;

(2) Checks the machine or equipment and the immediate area around the machine or equipment to ensure that all items such as tools and equipment have been removed from the area and that the machine or equipment components are operationally intact;

(3) Checks the work area to ensure that all personnel have been safely positioned or removed from the area;

(4) Notifies the affected employees that the lockout is going to be removed;

(5) Verifies that the controls are in neutral or in the “off” position;

(6) Removes the lockout and tagout devices and reenergizes the vehicle equipment or machinery;

(7) Notifies affected employees and authorized USIBWC supervisor that the servicing or maintenance is completed and that the vehicle, equipment or machinery is ready for use.

D. Transfer of responsibility under Lockout/Tagout (LOTO).

(1) The transfer of LOTO responsibility between authorized employees takes place at the worksite as follows:

• The departing authorized employee provides a complete status update to the arriving personnel and removes the personally-controlled lock and tag.

• The arriving authorized employee accepting the transfer must physically verify the lockout points. He/she installs their own lockout and tagout devices.

(2) The preceding processes are repeated as each authorized employee departs and

O-9 arrives at the worksite when the worksite is under LOTO.

E. Removing locks of other personnel.

(1) Each employee must remove their own lock when the maintenance procedure is complete. USIBWC personnel are forbidden to remove locks belonging to other personnel.

(2) In an emergency, the AOM, or the person currently designated to act on behalf of the AOM, is the only person authorized to permit removal of locks belonging to other employees.

(3) The AOM, or authorized acting AOM, must verify that the employee is not on site and make every effort to contact the employee before taking any action to remove the lock and if he/she does take action, assumes full responsibility for removal of the lock and must ensure that the machinery or equipment can be operated safely and will not endanger any other personnel.

(4) The AOM ensures that before the employee returns to work, the employee is informed that his/her lock has been removed.

F. Interrupting Lockout/Tagout (LOTO) for testing or troubleshooting. The authorized employee, in situations where LOTO has been implemented and there is a need for testing the machine or equipment before servicing and/or maintenance is completed, takes the following steps:

(1) Notifies the authorized USIBWC supervisor of intent.

(2) Clears the machine or equipment of all tools and materials.

(3) Directs all employees to clear the area near the machine or equipment.

(4) Removes only those locks/tags necessary to perform the test.

(5) Energizes the machine or equipment and performs the test.

(6) Shuts down the machine or equipment in the standard manner.

(7) Reapplies the locks/tags.

(8) Examines the machine or equipment to be sure all energy sources (stored) are relieved or neutralized.

(9) Verifies that LOTO is complete by:

• trying to start the machine or equipment using standard operating procedures, or

• using a test meter (such as a voltmeter) for electrical sources to verify that no

O-10 electrical energy is present.

(10) Notifies the authorized USIBWC supervisor that testing is completed.

G. Contractors and Lockout/Tagout (LOTO).

(1) The COR, and the Contractor shall fully coordinate all control activities with one another throughout the planning and implementation of these activities.

(2) The COR and the contractor shall inform the other of their Hazardous Energy Control Programs and LOTO procedures, ensure that their own personnel understand and comply with rules and restrictions of the procedures agreed upon to be used for the job, and ensure that their employees affected by the hazardous energy control activity are notified when the procedural steps outlined in the Hazardous Energy Control Program are to be initiated.

H. Group Lockout/Tagout (LOTO).

(1) Overview. Group LOTO is required when more than one employee is engaged in the performance of servicing and/or maintenance activities. Group LOTO procedures described in this section require each authorized employee to be in control of potentially hazardous energy hazards while performing servicing/maintenance work. Each employee in the group needs to be able to affix his or her personal lockout or tagout device as part of the group lockout.

(a) The placement of a personal LOTO device provides that employee with direct control over her own protection (until the device is removed), rather than having to rely completely on other people;

(b) The use of a personal device reinforces the right of the servicing and maintenance employee to verify that the equipment or machinery has been properly de-energized and isolated in accordance with the energy control procedure; and

(c) The presence of the individual employee’s lockout or tagout device on an energy isolating device informs all other persons, including the other authorized employees and supervisors, that the employee is still working on the equipment or machine and that it is not safe to re-energize the system.

(2) Organizational Structure of USIBWC Group LOTO

(a) Primary Authorized Employee Designation.

(i) The AOM shall designate a primary authorized employee. This employee exercises primary responsibility for implementation and coordination of the overall LOTO of hazardous energy sources for the equipment to be serviced.

(ii) Primary Authorized Employee Coordination.

O-11

• The primary authorized employee coordinates authorized employee changes and affected workforces (multiple work crews) with equipment operators before and after completion of servicing and maintenance operations that require

LOTO.

• This individual also has the responsibility to ensure continuity of protection with respect to multi-shift energy isolation (e.g., through the use of group continuity devices, such as "Job Lock" or "Operations Lock" procedures).

(b) Principal Authorized Employee Designation.

(i) The AOM shall designate a principal authorized employee(s) for each workforce or crew

(ii) When more than one crew, craft, department, etc., is involved, one principal authorized employee accounts for a single group of servicing/maintenance personnel. Each principal employee is responsible (to the primary authorized employee) for maintaining accountability and for the individual exposure status of each employee in that specific group in conformance with the company procedure.

(c) Employee Verification of Isolation

(i) Basic Individual Employee Verification

• Once the equipment is shut down and the hazardous energy has been controlled, maintenance/servicing personnel, sometimes in conjunction with operations personnel, must test the machinery or equipment to verify that the isolation of the equipment's energy source(s) is effective.

• Maintenance/servicing personnel must conduct a verification to ensure the continued isolation and de-energization of hazardous energy sources during the course of maintenance and servicing operations.

• Affected employees may walk through the affected work area to verify isolation. If there is a potential for the release or re-accumulation of hazardous energy, verification of isolation must be continued.

(ii) Alternative Individual Employee Verification System

• The AOM designates a primary authorized employee, with the primary responsibility for a set number of employees working under the group LOTO device(s).

• The primary authorized employee implements and coordinates the LOTO of hazardous energy sources and verifies that the steps taken, in accordance with the

O-12 specific energy control procedure, have in fact isolated the machine or equipment effectively from the hazardous energy sources. This must be accomplished before individual authorized employees participating in the group LOTO affix their personal lockout or tagout device to the group LOTO box and before they perform servicing/maintenance activities.

• When a primary authorized employee verifies isolation, all of the authorized employees participating in the group LOTO must be informed of their right also to verify the effectiveness of the lockout measures and must be allowed to personally verify that hazardous energy sources have been effectively isolated, if they so choose. An authorized employee who opts to verify the effectiveness of the isolation measures must perform this verification after affixing his personal lockout or tagout device to the lock box and before performing servicing/maintenance activities.

(d) Authorized Employees.

(i) Each authorized employee must affix a personal LOTO device to the group lockout device, group lock-box or comparable mechanism and remove that device when he or she is finished with the servicing or maintenance activity. No person may attach or remove another person's LOTO device, including signing on or signing off for another person.

(ii) For example, the authorized employee in charge of a crew (“Principal Authorized Employee”) does not remove the group lockout or tagout mechanism from the energy isolating devices until each employee in the group has removed their personal device.

Individual employee device removal indicates that employees are no longer exposed to the hazards from the servicing or maintenance operation.

(iii) Most importantly, these group LOTO devices (personal lockout or tagout devices; group LOTO mechanisms) ensure that the equipment LOTO devices are maintained on energy isolating devices throughout the "life of the job."

(3) Conventional Group LOTO Procedure.

(a) Group energy control procedures may need to be tailored to the specific industrial operation, but regardless of the situation, each employee performing servicing or maintenance activities must be in control of the associated hazardous energy throughout the entire period of their exposure.

(b) The Conventional USIBWC Group LOTO procedure is where each authorized employee places his personal lock or tagout device on each energy isolating device and removes it upon completion of the assignment.

(c) Each authorized employee verifies or observes the de-energization of the equipment.

O-13

I. Periodic Inspection.

(1) The AOM ensures that at least annually, a periodic inspection of LOTO procedures is completed to ensure adherence to all requirements of the hazardous energy control program. As a part of the inspection, each energy control procedure used at the facility is inspected.

(2) The certification must specify the system on which the energy control procedures were used when inspected, the date of the inspections, and the names of employees and included in the inspections.

(3) The periodic inspection is performed by an authorized employee who does not utilize the particular energy control procedure being inspected.

(4) Annual inspections of hazardous energy control programs and procedures must include a review between the inspector and employees involved in use of the procedures to assess individual, personal knowledge of, and responsibilities under the program.

(5) The authorized employee performing the periodic inspection documents any deficiencies and appropriate measures to correct the deficiencies and to ensure future compliance.

(6) The authorized employee performing the periodic inspection certifies that the inspections have been performed and passes the results to the AOM and Safety Officer.

6. Power Generation Safety Regulations. USIBWC power plants shall comply with the following OSHA regulations:

A. OSHA regulation 29 CFR1910.269, Electric Power Generation, Transmission, and Distribution. Applies to operation and maintenance of electric power generation, control, transformation, transmission, and distribution lines and equipment.

B. OSHA regulation 29 CFR 1910, Subpart S. Applies to USIBWC personnel while working on, near, or with the following installations:

(2) Wiring for connection to supply. Installations of conductors that connect to the supply of electricity; and

(3) Other wiring. Installations of other outside conductors on the premises.

(4) Optical fiber cable. Installations of optical fiber cable where such installations are made along with electric conductors.

O-14

7. Training.

A. Training Audiences

(1) Authorized Employees. The AOM shall ensure that all USIBWC personnel who have been designated as authorized employees receive training in 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.

(2) Affected Employees. The AOM shall ensure that each affected employee is instructed in the purpose and use of the energy control procedure.

(3) All other USIBWC personnel. The AOM shall ensure that all other USIBWC personnel whose work operations are or may be in an area where energy control procedures may be utilized, are instructed about the procedure, and about the prohibition relating to attempts to restart or reenergize machines or equipment which are locked out or tagged out.

B. Limitations of Tagout Systems. When tagout systems are used, the AOM shall ensure that USIBWC personnel are trained in the following limitations of tags:

(1) Tags are essentially warning devices affixed to energy isolating devices, and do not provide the physical restraint on those devices that is provided by a lock.

(2) When a tag is attached to an energy isolating means, it is not to be removed without authorization of the authorized person responsible for it, and it is never to be bypassed, ignored, or otherwise defeated.

(3) Tags must be legible and understandable by all authorized employees, affected employees, and all other employees whose work operations are or may be in the area, in order to be effective.

(4) Tags and their means of attachment must be made of materials which will withstand the environmental conditions encountered in the workplace.

(5) Tags may evoke a false sense of security, and their meaning needs to be understood as part of the overall energy control program.

(6) Tags must be securely attached to energy isolating devices so that they cannot be inadvertently or accidentally detached

C. Employee retraining.

(1) The AOM shall ensure that retraining is provided for all authorized and affected employees whenever there is a change in their job assignments, a change in machines, O-15 equipment or processes that present a new hazard, or when there is a change in the energy control procedures.

(2) The AOM shall ensure that additional retraining is conducted whenever a periodic inspection reveals, or whenever the employer has reason to believe that there are deviations from or inadequacies in the employee's knowledge or use of the energy control procedures.

(3) The retraining shall reestablish employee proficiency and introduce new or revised control methods and procedures, as necessary.

8. Recordkeeping. Under the HESP the following shall be maintained:

A. Safety Training Records. Training Records shall be maintained at the USIBWC Field Offices. Field Offices will forward copies to the USIBWC Safety Office.

B. Periodic Inspection. The Safety Officer will maintain certification of periodic inspection of the lockout/tagout program.

9. Supersession. This program supersedes Volume IV, Chapter 777 dated August 28, 2009, USIBWC Hazardous Energy Control Plan (Lockout-Tagout).

10. Effective Date. The provisions of this program are effective upon the date of issuance.

11. Definitions.

A. Affected Employee. An employee whose job requires him/her to:

• operate or use a machine or equipment on which servicing and/or maintenance needs to be performed under LOTO, or;

• work in an area in which LOTO is being performed.

B. Authorized Employee. A person authorized by USIBWC who locks out or tags out machines or equipment in order to perform servicing or maintenance on that machine or

O-16 equipment. An affected employee becomes an authorized employee when that employee's duties include performing servicing or maintenance covered under the USIBWC Energy Control Program.

C. Capable of Being Locked Out. An energy isolating device has a built-in lock, a hasp, or other means for affixing a lock. Other energy isolating devices are capable of being locked out if lockout can be achieved without dismantling, rebuilding, or replacing the energy isolating device or permanently altering its energy control capability (i.e., vendor devices that will make energy isolating device lockable).

D. Energized. Connected to an energy source or containing residual or stored energy.

E. Energy-Isolating Device. A mechanical device that when set in the "off" or "closed" position physically prevents the transmission or release of energy. Such devices include, but are not limited to, a manually-operated electrical circuit breaker, a disconnect switch, a flow control valve, or any similar device used to block or isolate energy. Push buttons, selector switches, or other control circuit devices are not energy-isolating devices.

F. Energy source. Any source of electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other energy. There are numerous types of energy sources other than electrical that must be identified and isolated during the LOTO procedures. The following are some of the more common examples:

• Chemical. An example is a battery which converts chemical energy to electrical energy.

• Electrical. The presence of voltage together with the movement of current which could result in a shock or electrocution.

• Gravity. The force of weight.

• Hydraulic. A device that is operated by the pressure created when a liquid is forced through a tube, etc.

• Pneumatic. The pressure or density of air or other gases in compressed form such as tanks of compressed air or helium.

• Thermal. Having to do with either freezing or heat in the form of liquid or air.

• Steam. The vaporized form of water.

G. Group Lockout/Tagout. Group LOTO allows authorized individual employees to be protected from hazardous energy when they are part of a group (two or more employees) performing covered servicing or maintenance. Group LOTO is the means by which each authorized employee performing the servicing and/or maintenance exercises his or her control over the associated hazardous energy by attaching his or her personal

O-17

LO or TO device onto a group LOTO mechanism. It consists of personal LOTO devices, group LOTO devices/mechanisms, and equipment LOTO devices.

H. Group Lockout/Tagout Mechanism. Any device or mechanism that, when used as part of a group LOTO system, permits each individual employee to use his personal lockout or tagout devices to physically secure energy isolating device(s) during the servicing or maintenance work. The use of group lockout hasps, lockboxes (containing keys or tabs from equipment locks or job tags) or similar group mechanisms, such as a master tag that procedurally controls equipment re-energization are examples.

I. Lockout. The placement of a lockout device on an energy isolating device, in accordance with established USIBWC procedures, ensuring that the energy isolating device and the equipment being controlled cannot be operated until the lockout device is removed.

J. Lockout device. A device that utilizes a positive means such as a physical lock, either key or combination type, to hold an energy isolating device in the safe position and to prevent the energizing of a machine or equipment. Included are blank flanges and bolted slip blinds.
