• 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 MSHAs list of most
  frequently violated standard
• But the REAL concern is for the health and well
  being of our employees.

• 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.

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 individuals 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
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 machines 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.

10
Definitions of Terms You Will Likely Hear
--Any Source of Electrical, mechanical,
hydraulic, pneumatic, chemical, thermal, gas,
water, steam, air or gravity.

• Energy Source

11

• 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

12
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.
13
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.

Electrical burns can be devastating!!!!
Electrical wounds consist of both an entrance
point and exit point
15
But electricity isnt the only energy source.

• Energy Sources
• Mechanical
• Hydraulic
• Gas
• Pneumatic
• Water
• Chemical
• Thermal
• Gravity
• Other stored energy (Springs, capacitors, etc)

16
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.

17
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
operators 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.
18
PH Shovel Hoist Rope Replacement
The following procedures have been established
for use when changing hoist ropes on PH 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.
19
You Will See Different Colored Tags.

• Red Tags are to indicate that the machine is NOT
  to be operated.
• Yellow tags are informational tags.

20
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.
