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
CONTENTS • Situations that require lockout tagout of hazardous energies. • Tagout only requirements • Lockout - tagout requirements • Special circumstances • Summary
WHAT IS HAZARDOUS ENERGY? Hazardous energy is the energy stored that if released may cause a serious accident or physical damage.
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.
5 TYPES OF HAZARDOUS ENERGY • Electrical • Chemical • Kinetic • Thermal Radiation • Pressure
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
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.
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.
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.
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.
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.
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
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
SPECIAL CIRCUMSTANCES • Abandoned locks • Change of shift • Multiple workers
SUMMARY • Types of hazardous energy with risks: • Electrical • electrical shock • burns • fire / explosion • secondary injuries • Chemical • chemical splash • inhalation • burns • dermatitis • cancer
SUMMARY • Types of hazardous energy with risks: • Kinetic • crushing of body parts • amputation • entanglement • Thermal Radiation • burns hot/cold • fire • eye injuries • skin cancer
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
Permit Issued By AuthorizedPerson FCT, PC, System Owner
Lockout - Tagout Procedure Must Be In Place Before Any Line Break Starts.
