9.1 Aims and objectives of CoHE Electrical Safety Refresher Training

Note The GWO COHE Electrical Safety Refresher Module is aimed towards improving the participants´ ability to “work safely” with electricity. This means that the CoHE Electrical Safety Module is not aimed at improving candidates´ technical knowledge, skills, and abilities regarding electricity. Participants should already possess the needed technical knowledge, skills, and abilities before attending the module. Similarly, it is not the intention of the GWO CoHE Standard to promote the acquisition of advanced knowledge, such as troubleshooting. Note:

The training is not aimed at improving technical capabilities regarding electricity or pressure fluid systems or the acquisition of advanced knowledge, such as troubleshooting. Before attending CoHE training participants should already possess technical knowledge, skills, and abilities in electrical or pressure fluid systems. V4 - V5 02.03.26
