![]() It is important to identify all isolation points in a system, as it may be necessary to use a local isolator to shut down a specific part of the machine, a motor for example, while the rest of the associated plant remains in operation. Plant and equipment that may require an isolation procedure should have appropriate isolation points for all energy sources so work on the plant can proceed safely. Authorised competent persons shall report any hazards noted during isolation of energy sources by reporting the hazard to the relevant UQ CFM or the person in control of the equipment. Depending on the plant or equipment, other hazards may include hazardous substances, such as gases, acids, alkalis and solvents, falls, burns, asphyxiation, impact. For example, associated equipment may need to be locked-out to prevent re-activation, or valves on pipes and lines carrying gases or fluids may need to be locked shut or blanked off. Similarly, shutting the plant or equipment down may require identifying other hazards and minimising or removing them to reduce the risk of injury. If original designer diagrams of plant installations are not available, new diagrams/photographs should be developed. If possible, an authorised competent person should use original designer diagrams of plant or equipment which show the location and details of its various components like isolation points, switches, valves, energy lines, pipes, power sources and control points, including computers, as part of the isolation procedures. The energy sources include electricity, including mains, solar and generator, fuels, heat, steam, fluids under pressure, such as water, air or hydraulic oil), stored energy, gravity, radiation. Isolation procedures should identify all energy sources likely to re-activate the plant and place people at risk. one switch before another) or by shutting down several energy sources.ģ.1.2 Identify all energy sources and other associated hazards However, complex plant or equipment may have to be shut down in a sequence (e.g. The operation of a single switch or valve can usually shut down plant or equipment that has a single energy source. However, every isolation procedure should include the steps outlined below. Isolation procedures in each task may vary because of differences in plant, equipment, power sources, hazards, and processes. LOTO isolation should be implemented and authorised as part of the safe system of work for protection against hazards. Increases productivity and reduced equipment downtime and damageĬost savings through lower insurance premiums. ![]() Minimised risk of injuries and fatalities This results in a safer workplace whilst performing critical maintenance, cleaning, and repairs. ![]() This can be prevented with clearly documented LOTO procedures and the performance of isolation and maintenance to protect people from exposure to any form of hazardous energy. In a work environment, a person may be injured or killed due to the unintentional release of hazardous energy sources. The guideline supports and should be read in conjunction with UQ’s Safe Use of Plant and Equipment Procedure. This guideline applies to work on plant or equipment on UQ campuses and sites, including work on or near equipment or mobile plant containing different forms of energy. The guideline provides UQ Client Facility Managers (CFM), Client Facility Coordinators (CFC) and supervisors with risk-based, practical tools and information to minimise the risk of incidents or injury using LOTO isolation. This guideline aims to reduce the risk of injury to people at The University of Queensland (UQ) working on plant or equipment by preventing the item and its components from being set in motion and preventing the accidental release of stored energy.
