Definition
Approach boundaries
As part of the risk assessment process for electrical work, approach boundaries should be determined. There are two shock protection boundaries; the Limited Approach Boundary and the Restricted Approach Boundary, that must be established in order to provide a safe distance for personnel from exposed, energized electrical components. For supporting guidance on good working practices on approach boundaries refer to Annex 5 Work instruction approved by the company responsible for the work described, according to its internal processes. Normally done with its corresponding risk assessment that will include the control measures for all risks identified. An explosive electrical discharge that occurs when current flows through the air between conductors, releasing intense heat (up to 19,000 °C), light and blast shock wave. This dangerous event can pose significant risks of burns and blast injuries.
Approved work instruction
Arc Flash
Bolt Tightening
Refers to the practice of tightening a bolt and includes both torquing and tensioning
Equipment that is suspected to be damaged and must be treated with more caution than equipment in its normal condition.
Deranged equipment
Discussion
The purpose of a discussion as a learning activity is to ensure that as many participants as possible reflect on the given topic by taking active part in the discussion. The instructor must arrange the participants in small groups or pairs to ensure that all participants are involved. The instructor can initiate a discussion by asking open-ended questions Any task performed on an electrical installation that requires specific electrical knowledge to be performed safely and correctly. Examples: install components, alter a circuit, take electrical measurements, replace a component, create an electrically safe work condition. Establishing an electrically safe work condition is the mandatory, step-by-step process of de-energizing, locking/tagging out, and verifying the absence of voltage on electrical equipment before work begins to prevent shock and arc
