									        Lock out Tag out
                           Its that easy
Lockout/tagout, or LO/TO, is a procedure in which repairs are not
made to machines until power sources are removed, locked out,
tagged out and isolated. Many serious accidents have happened
when someone thought a machine was safely shut off. LO/TO is a
way to protect yourself and others by ensuring that machines
remain completely, temporarily off.
  Equipment shutdown and isolation


o Notify affected employees of equipment that is to be
locked out before and after it is locked out, and the
reason for the lockout.
o Identify all the sources of energy, the hazards of that
energy and how the energy can be controlled.
o Identify all switches, controls, power sources to isolate
the system
o Shut down the equipment by normal stopping
procedures
o Disconnect and isolate the equipment from all its
sources of energy (including secondary supplies).
         Equipment specification
                Locks:

o Keyed differently, this should be verified upon
receipt of the locks
o Made by a reputable manufacturer
o Standardized in at least color, shape or size
o Durable
o Capable of withstanding the environments to
which they are exposed
o Cannot be forcibly removed without bolt cutters
o Will only be used for lockout/tagout
                           Tags:

o Standardized in print and format and in at least color, shape
or size
o Durable
o Will warn against hazardous conditions if the machine or
equipment is energized
o Indicate:
• The name of the person attaching the tag
• The name of the person authorized to removed the tag
• The reason the tag was attached
• The department responsible for the work
• Time and date the tag was attached
      Lockout/tagout application


o Sign out Lockout/Tagout equipment from the
Lockout/Tagout Station
o Inspect all equipment visually before every
use. Report damaged equipment to group
leader, supervisor or designated person
o Insert lock and tag (with work order, if
applicable)
o Double check your steps
  Control of stored
      energy
o Bleed off residual pressure in steam,
compressed air, hydraulic or other systems
checking that moving parts have stopped
turning
o Blank pipe flanges
o Install ground wires to discharge electrical
capacitors
o Secure or block elevated equipment that may
fall due to gravity
 Equipment isolation and verification

o After ensuring that no one is exposed, operate
the start button to ensure the equipment will not
operate and return the equipment to off or neutral
position.
o Test the equipment with a volt meter to verity de-
energization or identify other sources of energy
o Remove guards or covers as necessary
o Perform work
o Verify isolation periodically until maintenance,
service and repairs are completed
         Removal of locks and tags

o When work is completed, remove tools from work area
and reinstall guards or covers
o Ensure the system is fully assembled
o Check area and do a head count to ensure no one is
exposed. Warn employees to stay clear
o Remove locks and tags
o Restore power and run the equipment
o Notify affected employees that work is completed and
that equipment is returned to operation
o Record of all systems to be rendered inoperable will be
kept
         Remember in the USA
• OSHA’s standard for T he Control of Hazardous
  Energy (Lockout/Tagout), Title 29, Code of
  Federal Regulations (CFR), Part 1910.147,
  addresses the practices and procedures
  necessary to disable machinery, thereby
  preventing the release of hazardous energy while
  employees perform servicing and maintenance
  activities. The standard outlines measures for
  controlling hazardous energies – electrical,
  mechanical, hydraulic, pneumatic, chemical,
  thermal, and other energy sources.
