failure to have a formal Lock and Tag out program.

To ensure the safety of employees who work with mechanical
and electrical equipment.

•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.
Policy

7. 7
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.

8. 8
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.”


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.

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.
