Control of Hazardous Energies Standard / V3 2023-12-04
Ask the participants involving questions about the approach boundaries related to exposed high voltage parts e.g.:
a. what are the key differences between the approach boundaries related to energised exposed electrical conductors/parts and the approach boundaries related to exposed high voltage parts?
Facilitate a learning activity with the participants about how approach boundaries are connected to ‘test before touch’ and establishing an electrically safe work condition
Mention that later in the module, the connection between approach boundaries will be revisited as part of the establishing an electrically safe working condition lesson
Approach boundaries are connected to ‘test before touch’ and establishing an electrically safe work condition, because as part of establishing an electrically safe work condition, absence of voltage in all isolations must be tested first. After this, the absence of voltage in the working area must be tested according to the approach boundaries Provide the participants with a minimum of two examples of tasks defined as electrical work (the tasks should only be presented to the participants and not carried out or completed), where different PPE is required:
Note
• Task 1) Visual inspection from within the limited approach boundary, but outside of the restricted approach boundary o Answer: minimum electrical PPE (that is, non-melting clothing to include long trousers and long sleeves, safety glasses and safety footwear that fully covers the feet) • Task 2) Switching or testing including establishing an electrically safe work condition within the restricted approach boundary o Answer: Minimum electrical PPE + insulating gloves required Guide the participants to discuss and determine what PPE is required in the examples of tasks (previous points) defined as electrical work and give constructive feedback throughout this activity
Lead discussions with participants about:
a. what are the differences in the required PPE for each of the tasks?
b. why are there differences in the required PPE for each of the tasks?
Facilitate practice for the participants in how to act safely in a WTG environment with energised exposed electrical conductors and circuit parts based on the learnings from this element
Give constructive feedback to the participants´ performance throughout the activities of this element
