1. LOTO – Energy Isolation Process

2. HAZARD RECOGNITION
Kinetic
Something that might
move and present a
hazard?
Potential
Is there stored energy
that might suddenly
be released?
Electrical
Accidental
contact with
electrical energy?
Chemical
Is there a chemical
hazard that might
be released
Thermal
Hazardous
temperature can be
hot or cold
Pneumatic
Air or gas present a
hazard if not properly
controlled
Hydraulic
Fluids present a
hazard if not properly
controlled
Energy isolation exists to protect workers through the control of hazardous energy. Remember,
equipment may have more than one potential energy source.
The Lock Out, Tag Out requirements helps to control the potential hazards.
Pressure
Trapped pressure or
pressurized
equipment

3. Employee Training
Contractors are required to provide suitable
training on LOTO to ensure the employee are
competent and trained in the procedure.
The authorized and competent
employee will know how to refer to the
company procedures to identify the type
and magnitude of the energy that the
machine or equipment utilizes and know
the methods to control the energy.
Affected employee performs
the duties of his or her job in an
area in which the energy control
procedure is implemented and
knows not to remove the tag or
lock which is there for their
safety.
The lockout/tagout training establishes the
employer’s responsibility to protect employees from
hazardous energy sources on machines and
equipment; and to ensure that lockout/tagout
devices identify the individual users.
It also helps to identify and defines the authorized
and affected employees' roles and responsibilities.
Remember, a tag use solely by itself is just a
warning sign, not a physical locking device to
prevent the equipment from being accidentally
restarted.

LOTO Application Process
Lockout/Tagout rules apply when:
Removal or bypassing machine
guards or other safety devices, risk
of body contact or required to work
in a danger zone of an operational
machine.
If an energy-isolating device is
capable of being locked out, it
must be locked out unless it can
be shown that a tagout system
provides full employee protection
and approved by an Oxy
representative.
Engage all the energy-isolating
devices so that the equipment is
isolated from its energy sources,
Be sure to isolate all energy
sources (secondary power
supplies as well as the primary
supplies).
Never simply remove a fuse instead of
disconnecting the equipment as there
may be an uninterrupted power supply
attached as an emergency backup
power source.

6. Energy Isolation (LOTO) Procedural Steps
The established steps for any isolation of energy (LOTO) are:
Identify The Power Sources
Conduct the TBT and include
the affected employees
Review the JSA’s
Raise the PTW and
Isolation certificates
Follow the equipment
shutdown procedures
Authorized person(s)
Installs the appropriate
isolations and tags and
then verifies isolations.
Now Test The
Equipment yourself to
ensure it is isolated!
If you believe the job
is unsafe, stop the
work and check the
isolations again.

7. Energy Isolation (LOTO) Procedural Steps
The locks used must be unique to the isolation process and
not used for another purpose.
If more than one group is working on the same item
(including different maintenance crafts), each person
performing service or maintenance on the equipment shall
place a lock on the multiple hasp and sign and date the
“Danger, Do Not Start” tag. Locks must not be applied without a tag stating who applied the lock,
the reason for the LOTO, and the date

8. Completion and Release from LOTO
The following steps should be completed, before energy is restored to the isolated equipment:
Job complete and the
equipment ready to
be energized?
Everyone informed the
equipment is being
energized again and clear
of the equipment?
Re-energize the machine, in
accordance with the start-up
procedures or guidelines
specific to the machine or
equipment
Everyone who applied a
lock or tag removed each
locking or tagging device
from the energy isolation
device
If the original authorized employee who applied the lock or tag is unavailable to remove his personal lock out tag out device,
this can be removed after confirming the above steps and after the supervisor approves the removal of the lock and tag.
When there is a shift change or change in personnel, and the isolation is still required then the transfer of LOTO device
protection between off-going and oncoming employees is performed, this ensures the isolations remain in place until the
release is requested.

9. 9
Contractors
The Oxy Supervisor and Contractor Supervisor shall inform each other
of their respective LOTO procedure and develop a common
understanding of how the procedures interact and must be reviewed by
HES.
The contractor has the option to use their own LOTO procedure. If the
contractor does not have an equivalent LOTO procedure, they must
follow the LOTO requirements outlined in the Oxy guideline.
Oxy personnel working on the location of the contractor will understand
and comply with the contractor’s LOTO procedure. Oxy personnel must
understand and comply with the contractor’s LOTO procedure but must
still follow the requirements of OMAN-HES-210 Process
Mechanical/Isolation procedure and this procedure.

to lock out
Mains power switch isolation and electrical door panel locks
Lockout devices shall be applied in a manner that will hold the energy isolating device in a “safe” or “off” position. Use
of an assigned personal lock is recommended.

20. Key Lock Boxes
It's important to ensure the lock box can be secured
and the key retained with the unit supervisor

21. Job Safety Analysis
JSA requirement for all tasks including all repairs
and maintenance of rig equipment – All JSA’s
