1 1Hazards CONTROL OF HAZARDOUS ENERGIES (LOCKOUT / TAGOUT)

2 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

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

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

5 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.

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

7 7Hazards 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

8 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.

9 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.

10 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.

11 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.

12 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.

13 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

14 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

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

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

17 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

18 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

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

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