Summary
WHAT IS HAZARDOUS ENERGY?
Hazardous energy is the energy stored that if
released may cause a serious accident or physical
damage.

Hazards
CONTROL OF HAZARDOUS
ENERGIES
 Purpose:
To ensure persons who work on or around
hazardous energy sources are aware of controls to
prevent injury or accidents.


220 - 380 v, high voltage - substations
pressurised gases, vacuum pumps, pneumatic cylinders
LOCKOUT - TAGOUT

Lockout
The placement of a lockout device on an energy isolation
device. This ensures that the energy isolating device and
the systems it controls cannot be accidentally operated.


Hazards
Tagout
The placement of a tagout device on an energy isolation
device to indicate that the isolation device and the system
being controlled may not be operated until the tagout
device is removed.
GENERAL REQUIREMENTS
9
Hazards

Any equipment able to store hazardous energy must have
lockout and tagout capability.

Only trained and authorised persons can perform lockout tagout.

A lockout - tagout device cannot be removed on behalf of
another person, unless an approved transfer procedure has
taken place.
SITUATIONS REQUIRING THE USE OF
LOCKOUT - TAGOUT
10
Hazards

When servicing, maintaining or repairing mechanical equipment where
parts could create a safety hazard.

When working on pipelines that carry hazardous chemicals (e.g. high
pressure, toxic, corrosive, etc.).

On electrical circuits and systems where a high risk of electrical shock
exists.

Where other hazardous energies exists that may cause injury if
intentionally released during service or maintenance.
TAGOUT
11
Hazards

Tagout alone is permitted only in circumstances where a
lockout device cannot be used.

Seek approval from your supervisor before commencing
any work on equipment that cannot be locked out.

It is your responsibility to remove your tag or lock prior to
closeout of the work permit.
TAGOUT REQUIREMENTS

A tag may only be removed by the person who attached it

A tag should never be bypassed, ignored or defeated

A tag must be able to withstand the environmental conditions

A tag must be securely attached so it is not inadvertently defeated

A tag must only be transferred when ownership has to be changed for a task

The new Owner must affix his tag with all relevant details and ensure the work
permit shows the same details.

Hazards
LOCKOUT - TAGOUT REQUIREMENTS
13
Hazards

Always follow the site lockout and tagout rules to control
hazardous energies

Use only approved locks and tags

A lock or tag may only be removed by the person who
applied it

Always use a multiple lockout clasp in case others need to
lockout
LOCKOUT - TAGOUT REQUIREMENTS
14
Hazards

Only one key to one lock

Where a machine or its supporting equipment are to be
worked on all relevant permits must be used

Where piped systems or exhaust ducting is to be worked
on, then the system Owner must sign off the respective
permits
