INTRODUCTION

• Blocks flow of energy from power source to the
  equipment
• Provides means of warning (Lock Tag), when
  servicing or maintaining equipment
• Used if hazardous energy exists
• Unexpected or remote start-up could occur
• Either of these could harm an employee

3

DEFINITIONS

• Authorized Employee employee authorized to
  conduct work
• Affected Employee employee working in area of
  the Lock Out equipment being serviced
• Energy Isolating Device mechanical device that

Why/When is a lockout required

• To prevent the unexpected startup or release of
  stored energy.
• Anytime an employee places any part of his body
  in the danger zone of a piece of equipment.

Lockout/Tagout Procedures
Machinery or equipment shall be turned off or
shut down using the procedure established. An
orderly shutdown must be utilized to avoid any
additional or increased hazard to employees as a
result of equipment shutdown.
21
Lockout/Tagout Procedures
Lockout or Tagout devices must be affixed to each
energy or isolating device by the employee
authorized by the supervisor in charge. The
devices shall be attached in a manner that will
hold the energy isolating devices in a safe or
off position.
22
Lockout Procedure
When following Lockout / Tagout procedure you
should identify all energy sources. Only
qualified personnel will attach Lockout / Tagout
devices. Equipment must be tested after
locks/tags are in place. Qualified person
removing last lockout device must make sure work
is completed and equipment is in a safe
operational condition.
23
Lockout Procedure

• Only authorized employees apply a lockout device
• Notify affected employees
• Identify all energy sources and isolate

24
Lockout Procedure cont

• Apply lockout device
• Verify isolation of energy (try to start
  equipment)
• Complete permit

25
Lockout Procedure cont

• Perform work
• Same person removes the lock or assigns the
  authority to the next crew

26
Tag Outs
To be used when a lockout is not possible due to
equipment design. Tags must be securely attached
to equipment.
27
Lockouts/Tagouts are for your protection, use
them correctly!

• All energy sources must be disabled before work
  can continue!

28
TYPICAL LO/TO PROCEDURES

• Performing a shutdown
• Isolating equipment
• Applying and removing lockout devices
• Safely releasing stored energy

29
PERMITS TO WORK

• Obtaining fully endorsed permit before starting
  non-routine operations
• When in doubt Fill one out!

30
PERMIT TO WORK

• Filling out the permit to work with the details
  of the job to be done, the exact location, and
  the tools to be used
• The performing authority controller then details
  the precautions required such as (LO/TO, Fire
  Watch, etc.) before and during the job, and may
  include a time limit for permit validity
• When these precautions have been detailed, the
  work permit is retained by the permit controller
  until the preparations, such as LO/TO, are
  completed
• When all such actions are complete the permit
  authority signs the work permit and the job can
  be started

31
JOB SAFETY ANALYSIS (JSA)

• Can be used with Line Manager approval in place
  of permit to work
• Must be prepared by all Crew, explained to all
  employees
• Signed by all employees doing the job
• Perform Hazard Analysis Risk Control

32
ENERGY ISOLATION

• Employee involved must be knowledgeable of type
  amount of energy
• Notify surrounding affected co-workers, and any
  affected service company personnel, of shut down
• Equipment shut down must be done in accordance to
  manufacturers instruction
• Perform Hazard Analysis Risk Control

33
ENERGY ISOLATION

• Needed LO/TO devices shall be located and used
  properly
• Lock and Tag. Date and sign tag.
• Relieve stored energy, e.g., draining,
  disconnecting, etc.
• Inform surrounding workers and test to ensure
  locked out properly
• If absent for a period of time check to ensure
  equipment has not been returned to service (shift
  change, break, lunch, etc.)
• Should be noted in shift hand over notes

34
RESTORING ENERGY

• After completion of repairs the lock and tag
  device can be removed
• Inform surrounding workers that device will be
  restarted
• Ensure that equipment is operationally ready to
  be started
• Only restart when deemed safe for you and
  surrounding coworkers

35
LOCKS AND TAGS REQUIREMENTS

• Paper or Plastic Tags Must be non-reusable
• Locks Must be attached by hand
• Locks Must be self locking
• Locks Must be with a minimum unlocking strength
  of 50 pounds approximately 25 kg
• If no locks are available, then one piece nylon
  cable tie-wrap is temporarily acceptable if used
  with a tag

36
CONCLUSION

• LO/TO is practiced when servicing and performing
  maintenance on machines and equipment
• Done to isolate energy to prevent injuries to
  worker and surrounding co-workers
• Employees must take responsibility for their
  safety and that of their co-workers
• Can save your life!
