25
WHAT IS HAZARDOUS ENERGY?
Hazardous energy is the energy stored that if
released may cause a serious accident or physical
damage.
26
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.
27
5 TYPES OF HAZARDOUS ENERGY

• Electrical
• Chemical
• Kinetic
• Thermal Radiation
• Pressure

28
TYPES AND RISKS

• Electrical
• 220 - 380 v, high voltage - substations
• Chemical
• reaction, fire, explosion
• Kinetic
• release of a spring, moving parts, falling
  objects
• Thermal Radiation
• hot/cold, radiation
• Pressure
• pressurised gases, vacuum pumps, pneumatic
  cylinders

29
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.
30
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.
31
GENERAL REQUIREMENTS

• 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.

32
SITUATIONS REQUIRING THE USE OF LOCKOUT - TAGOUT

• 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.

33
TAGOUT

• 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.

34
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.

35
LOCKOUT - TAGOUT REQUIREMENTS

• 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

36
LOCKOUT - TAGOUT REQUIREMENTS

• 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

37
SPECIAL CIRCUMSTANCES

• Abandoned locks
• Change of shift
• Multiple workers
