GWO CoHE Training Standard V0
Visual inspection (as far as we are not entering restricted approach boundary).
Assign the participants into small groups (a maximum of four participants per group)
Present examples of hazardous situations or scenarios in a WTG environment where the participant groups have to discuss and analyse when and why an electrically safe work condition has to be established. NOTE: Please emphasise that participants should always comply with company specific rules and procedures along with national and regional legislation. This means that the answers to the examples could change depending on regional/company/WTG model rules.
The participants shall:
Analyse examples of hazardous situations or scenarios in a WTG environment in participant groups and discuss and provide answers to when and why an electrically safe work condition has to be established.
The instructor shall:
Give constructive feedback to the participants groups´ discussions and answers to enable that all participants can explain when to establish an electrically safe work condition.
ELEMENT 5.3 - HOW TO ESTABLISH AN ELECTRICALLY SAFE WORK CONDITION
