Lockout/ Tag Out Training in Vaughan, Woodbridge, Brampton,Mississauga and Toronto

What is Lockout?
‘Lockout’ means to physically neutralize all energies
in a piece of equipment before beginning any
maintenance or repair work. Lockouts generally
ƒ Stopping all energy flows (for example, by
turning off switches, or valves on supply lines
which are called energy-isolating devices)
ƒ Locking switches and valves (i.e., putting
lockout on those energy-isolating devices)
ƒ Securing the machine, device, or power
transmission line in a de-energized state (for
example, by applying blocks or blanks, or
bleeding hydraulic or pneumatic pressure
from lines)
Why is a Lockout Necessary?
If a lockout is not performed, uncontrolled energies
could cause:
ƒ Electrocution (contact with live circuits)
ƒ Cuts, bruises, crushing, amputations, death,
resulting from:
– Entanglement with belts, chains, conveyors,
rollers, shafts, impellers
– Entrapment by bulk materials from bins
silos or hoppers
– Drowning in liquids in vats or tanks
ƒ Burns (contact with hot parts, materials, or
equipment such as furnaces)
ƒ Fires and explosions
ƒ Chemical exposures (gases or liquids released
from pipelines)
Often power sources are inadvertently turned
on, or valves opened mistakenly before the work
is completed, resulting in serious injuries and
fatalities. Therefore, it is important not only to
ensure that all energies are properly locked out, but
also that they remain locked out until the work is
How is a Lockout Done?
For lockouts to be effective, a clear, well-defined
lockout policy supported by administrative and
control procedures and proper training, is essential.
A systematic approach would be to:
ƒ Develop a lockout policy
ƒ Identify lockout situations
ƒ Develop procedures
ƒ Train workers
ƒ Enforce and update your policy
Develop a Lockout Policy
Your written lockout policy should make reference
to your company’s general occupational health
and safety policy. It should clearly outline
responsibilities, and refer to procedures to be
followed. It should state your company’s intent to
protect all employees by:
ƒ Identifying all activities and machines,
equipment, and processes which require
lockouts (for example, repairs, maintenance, and
cleaning of pipelines, tanks, and machines);
ƒ Making the appropriate persons responsible for
ƒ Ensuring that lockouts are performed by
authorized persons only

ƒ Developing procedures for each specific lockout
ƒ Training those who will perform lockouts
ƒ Verifying the effectiveness of such training
ƒ Reviewing, updating, and enforcing the lockout
Identify Lockout Situations
Assess all processes, machinery, energies, and work
activities to identify where and when lockouts are
needed. Maintenance work will probably be the
major focus of lockout needs. A useful source of
information may be workplace inspections, and
recommendations from your joint health and safety
committee or health and safety representative.
List every machine, device, or process that will
require a lockout. Against each, list the energy
forms involved. Different energy forms will require
different procedures. More than one lockout may be
required for a single machine or system.
Safety Coordinator
ƒ Train all staff in lockout procedures and
maintain records of this training
ƒ Receive reports of locks being cut or removed
because of lost keys, etc. and report to the
General Manager any recommendations as
ƒ Ensure that lockout procedures are understood
and followed by all employees as required
ƒ Co-ordinate work beyond shift with other
supervisors as appropriate
Equipment Operator
ƒ When assigned to operate equipment that had
been locked out for any reason, review the
condition of that equipment to ensure that all
guards are in place and that the equipment is
ready to begin operations
ƒ If equipment is unsafe, report the condition
to your supervisor. If you must leave the
equipment to make this report and there is a
possibility that someone else may operate it,
lock the equipment out with your operator lock
and tag before leaving the equipment
Person Installing Lock
ƒ Recognize that lockout is needed. If in doubt,
ask your supervisor. Ensure that all energy
sources are locked out and that ram blocks, etc.,
are used
ƒ Attach the lock using the required attachments
as appropriate. Test operating controls to see
that the lockout has been effective
ƒ Attach a tag to the lock or to equipment as
ƒ Remove lock and tag when your work is finished
Develop Procedures
Procedures must be in writing and communicated
to all employees and departments. Administrative
procedures for lockouts in general should include
the following:
ƒ Supervisors to be notified of lockouts in their
ƒ Lockout to stay in effect if work is not
completed at the end of the shift
Control procedures involve developing separate (i.e.,
not-generic), detailed, written lockout procedures
for each identified machine, device or process that
may require to be locked out at some time. The
procedure should identify:
ƒ The person responsible for performing the
lockout (for example, operator, millwright,
ƒ The person responsible for ensuring that the
lockout is properly performed (for example,
maintenance supervisor and/or site supervisor)
ƒ The energy sources to be controlled by the
