Lockout/Tagout/Verify Awareness HOW YOU PLAY A PART

Have you ever touched and electric fence?

Electrical Incidents In real life, it’s very seldom funny!!!

History • More citations • More costly fines • 95% of all lockout/tagout citations involve the failure to have a formal Lock and Tag out program. • Remains near the top of MSHA’s list of most frequently violated standard • But the REAL concern is for the health and well being of our employees.

Related References • 30 CFR and TransAlta Centralia Mining LLC policy, Purpose To ensure the safety of employees who work with mechanical and electrical equipment.

Policy • Whenever work is to be performed on any electrical circuit, a qualified person(s) as defined by 30 CFR 77.103 will perform it. All work will comply with 30 CFR Part 77.500 & 501. • Qualified person will determine that the circuit is de-energized, that visible disconnects are open, and that the circuit is tagged and locked out. • On all high voltage distribution circuits, work will comply with 30 CFR 77.704. A qualified person as defined by 30 CFR 77.103 must ensure that each ungrounded conductor of the circuit is properly connected to the system-grounding medium. • Each employee is responsible for their own safety by locking out and tagging the equipment or machinery before commencing repairs or performing maintenance activities. If there is any question as to the proper place to lock out, consult with the supervisors or electricians.

Every person working on the machine/equipment must use his/her own lock and tag. Never remove someone else's lock or tag. Every employee working on equipment, that if energized or operated would present a safety hazard, is issued the necessary individually keyed Safety Lock. This lock must be used whenever practical to effectively LOCK OUT a piece of equipment. Whenever a Safety Lock is used, the individual’s Red Tag must accompany it, if a department locks, by a Department Red Tag. Work may not commence on any electrical or mechanical system unless the appropriate mechanical system and/or electrical control box is completely and safely LOCKED OUT. The installation and removal requirements of the Safety Lock are the same as those for Individual Red Tags.

This Red Tag and Lock Out procedure is consistent with the MSHA policy of 77.404 and 77.500 which states: “It is not necessary to completely de-energize large surface mining equipment where means are provided in the equipment to de-energize any part where repair work is to be done. Similarly, it is not necessary to completely de-energize large surface mining equipment where the motion of the operating equipment does not pose a hazard, and means are provided in the equipment to de-energize that part where repair or maintenance work is to be done. Each repair or maintenance job must be examined separately for hazards related to that particular job or work area. If the machine’s operation poses a hazard to the employee performing the work, the machine shall be shut down until the work is completed or the hazard no longer exists. General maintenance and housekeeping can normally be performed while the machine is in motion except around unguarded energized electric or moving mechanical equipment.”

Lockout/Tagout Procedures • The purpose of lockout/tagout is to prevent energy from accidentally being released while a machine or equipment is being serviced. • The ultimate goal of lockout/tagout is to protect the safety and health of employees. • Secondary is the protection of equipment from damage.

Definitions of Terms You Will Likely Hear : --Any Source of Electrical, mechanical, hydraulic, pneumatic, chemical, thermal, gas, water, steam, air or gravity. Energy Source:

Definitions (continued) • Lockout/Tagout: • The placement of a lock/tag on an energy isolating device, in accordance with an established procedure, to ensure that the energy isolating device and the equipment being controlled cannot be operated until the lock and tag is removed • In addition to tag/lock out, the equipment must be blocked against motion and any residual energy removed. • Lockout device: • A device that utilizes a positive means such as a key lock to hold an energy isolating device in the safe position and prevents the energizing of a equipment

Isolating Device • A mechanical Device That Physically Prevents The Transmission or Release of Energy. Examples are: --disconnect switches, slide gates, valves, blocks, and blind flanges. E-Stops are not included in isolation devices.

Lockout/ Tagout • The placement of a lock and tag on an isolating device which ensures that the equipment being controlled cannot be re-energized until the locking device is removed. NAME: Date: Reason :

Electrical burns can be devastating!!!! Electrical wounds consist of both an entrance point and exit point

But electricity isn’t the only energy source……. • Energy Sources: • Mechanical • Hydraulic • Gas • Pneumatic • Water • Chemical • Thermal • Gravity • Other stored energy (Springs, capacitors, etc)

Equipment Specific Procedures Specific procedures for : • shutting down the equipment. • isolating from its energy source. • blocking from residual energy source. (Blocked against motion) • securing equipment for work.

Bucket Teeth and Hoist Rope replacement The following procedures have been established for use when changing teeth on dragline buckets. These procedures are accepted industry standards and are recommended by Bucyrus-Erie: The dragline operator will lock out excitation on the operator’s console with a key and remove the key when it is in the off position. He shall use a red tag with his name on it, along with what is being done to the machine. He shall leave the tag secured to the console. After the operator removes the key and the red tag is in place, the operator, along with the oiler and groundman, may proceed to change the bucket teeth. This does not change the procedures to be followed when a P.M. is in progress, as noted previously. Prior to re-energizing excitation, the operator will be responsible to see that all persons are in the clear before removing the red tag and unlocking the line excitation switch.

P&H Shovel – Hoist Rope Replacement The following procedures have been established for use when changing hoist ropes on P&H 4100 shovels: To remove hoist rope from the drum, set the hoist drum control to “local” in the revolving frame hoist control cabinet. This will disengage joystick controls in the cab to motions. After hoist ropes have been removed from the drum, and drum rotation is not needed, lock out the whole machine at “Main Lock Out” switch. When new hoist ropes are ready to be installed, make a decision if hoist drum needs to rotate. To rotate the hoist drum, start the machine from cab, switch hoist drum control to “local” in revolving frame. Once rotation of the hoist drum is complete, lock out the whole machine at the “Main Lockout” switch.

You Will See Different Colored Tags. • Red Tags are to indicate that the machine is NOT to be operated. • Yellow tags are “informational” tags.

Red Tag • Means “EXTREME DANGER. DO NOT OPERATE AND DO NOT REMOVE." • Used whenever there is a hazard or someone working on or near a piece of equipment or electrical system. • Shall be used to tag out a piece of equipment or system that is UNSAFE to operate in its present state or condition. • Must be filled out completely, including Name, Date, and Reason for Red Tag. Whenever unsafe equipment is red tagged, contact Dispatch. Notify them of the unit number, equipment failure, and that the equipment is down and red tagged. The dispatcher will enter Unit #, cause for being Red Tagged. • Unauthorized removal of a Red Tag or utilization of a system or piece of equipment TAGGED OUT will result is disciplinary action up to and including discharge.

Red Tag Cont. • Will be available to every TransAlta Centralia Mining employee required to work on or near equipment or facilities that when energized or operated would present a personal safety hazard. • Shall be used in conjunction with a Safety Lock whenever possible. • May be removed only by the individual whose name is on the tag or by the authorized person assigned by the Maintenance Foreman who will determine that the condition has been corrected and that all persons are in the clear. Failure to remove a Red Tag prior to leaving the property if the necessary repairs or corrected unsafe conditions are completed, or failure to remove the Red Tag and replace it with the appropriate Departmental Red Tag if the repair or unsafe condition/s are not corrected, will result in disciplinary action up to and including discharge.

Departmental Red Tags • May be installed or removed by any authorized person. Unauthorized removal of a Red Tag will result in disciplinary action up to and including discharge. • Will be used when jobs go to the next shift or shifts. The Departmental Red Tag must remain in place until the unsafe condition is eliminated or the job is completed.
