CONTROL OF HAZARDOUS ENERGIES (LOCKOUT / TAGOUT)

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 Generally used by maintenance fitters/electricians Can be used by m/c operator (e.g. crusher)

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. Cannot be seen in many cases and may trigger repercussions or knock effects

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. To give confidence to maintenance employees Maybe cleaning _________ 1/year isolations

5 TYPES OF HAZARDOUS ENERGY Electrical Chemical Kinetic Thermal Radiation Pressure Static discharge - fits under electrical Lighting - fits under electrical

TYPES AND RISKS Electrical Chemical Kinetic Thermal Radiation Pressure 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 220 - 380: common to tool or equipment in fabs Chemicals: must be compatible when stored

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. Design and specifications for control equipment, today try to incorporate LO/TO capability

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. The norm is for tags to be attached to the lock, providing the necessary information

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 All parts of any supportive equipment items must be included in the isolation Two areas of work may be occurring on the same pipework system

SPECIAL CIRCUMSTANCES Abandoned locks Change of shift Multiple workers All efforts will be made to bring back to site any person who fitted a lock or tag and left without completing the procedure

SUMMARY Types of hazardous energy with risks: Electrical Chemical electrical shock burns fire / explosion secondary injuries Chemical chemical splash inhalation 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 Do not remove any “hold off” tag unless authorized to do so Report immediately any damaged or defaced tags or locks

Permit Issued By Authorized Person FCT, PC, System Owner

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