1Hazards CONTROL OF HAZARDOUS ENERGIES (LOCKOUT / TAGOUT)

2Hazards CONTENTS  What is hazardous energy?  Purpose for controlling hazardous energies.  5 types of hazardous energies.  Types and associated risks.  Procedure for controlling hazardous energies. requirements for hazardous energy equipment who performs the lockout - tagout how is the lockout tagout device removed effect of control of hazardous energy equipment

3Hazards CONTENTS  Situations that require lockout tagout of hazardous energies.  Tagout only requirements  Lockout - tagout requirements  Special circumstances  Summary

4Hazards WHAT IS HAZARDOUS ENERGY? Hazardous energy is the energy stored that if released may cause a serious accident or physical damage.

5Hazards 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.

6Hazards 5 TYPES OF HAZARDOUS ENERGY  Electrical  Chemical  Kinetic  Thermal Radiation  Pressure

7Hazards TYPES AND RISKS  Electrical 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

8Hazards 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.  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.

9Hazards 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.

10Hazards 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.

11Hazards 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.

12Hazards 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.

13Hazards 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

14Hazards 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

15Hazards SPECIAL CIRCUMSTANCES  Abandoned locks  Change of shift  Multiple workers

16Hazards SUMMARY  Types of hazardous energy with risks: Electrical electrical shock burns fire / explosion secondary injuries Chemical chemical splash inhalation burns dermatitis cancer

17Hazards SUMMARY  Types of hazardous energy with risks: Kinetic crushing of body parts amputation entanglement Thermal Radiation burns hot/cold fire eye injuries skin cancer

18Hazards SUMMARY  Types of hazardous energy with risks: Pressure punctures secondary injuries bends - air blockage in the bloodstream physical hazards - flying particles Control all potentially hazardous situations by using a lockout - tagout system

19Hazards Permit Issued By Authorized Person FCT, PC, System Owner

20Hazards Lockout - Tagout Procedure Must Be In Place Before Any Line Break Starts.
