The Lock Out / Tag Out (LOTO) guidelines support the university's health and safety policy by establishing controls to eliminate risks associated with the potential release of energy during servicing, commissioning, repairing, or modification works on plant and equipment.

| 1 | • Definitions: Understanding terms like Authorised Person, Energy Sources, Isolation of Plant, Isolation Procedure, Lockout Devices, and Plant. |
| 2 | • Lock-Out and Tag-Out Rules: Requirements for attaching lock-out devices, retaining keys, managing multi-person lock systems, and handling unfinished jobs at the end of a shift. |
| 3 | • Types of Tags: • Out of Service Tags: Yellow and black tags indicating unserviceable plant. • Personal Danger Tags: Red and white tags used when work is undertaken on machinery that could cause injury. |
| 4 | • Step-by-Step Isolation Procedures: Shutting down plant, de-energizing sources, applying locks/tags, controlling other hazards, and testing isolation. |
| 5 | • Energy Sources & Hazards: Identifying electricity, chemicals, fuels, heat, steam, pneumatic pressure, pressurized fluids, stored energy devices (springs, batteries, capacitors), gravity, and radiation, alongside secondary hazards like burns, falls, and asphyxiation. |
| 6 | • De-Isolation and Re-Instatement: Conditions for safely removing locks, notifying relevant personnel, conducting visual inspections, and managing supervisor removals in specific situations. |
| # | Outcomes |
|---|---|
| • Ability to identify all relevant items of plant, associated hazards, and multiple energy sources (such as electrical, fluids under pressure, and fuels). | |
| • Competency in applying correct lock-out devices, personal locks, and tags at energy isolation points. | |
| • Understanding of how to safely discharge stored energy before commencing work. | |
| • Knowledge of proper testing protocols (using instruments and attempting to re-activate plant) to verify isolation effectiveness before starting work. | |
| • Mastery of the de-isolation and re-instatement process once maintenance is completed |
