  1. CONTROL OFHAZARDOUS ENERGIES(LOCKOUT / TAGOUT)

  2. 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. CONTENTS • Situations that require lockout tagout of hazardous energies. • Tagout only requirements • Lockout - tagout requirements • Special circumstances • Summary

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

  5. 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. 5 TYPES OF HAZARDOUS ENERGY • Electrical • Chemical • Kinetic • Thermal Radiation • Pressure

  7. 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. 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. 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. 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. 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. 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. 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. 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. SPECIAL CIRCUMSTANCES • Abandoned locks • Change of shift • Multiple workers

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

  17. 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. 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. Permit Issued By AuthorizedPerson FCT, PC, System Owner

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