7. HIGH VOLTAGE OPERATIONS

7.1 Aims and objectives for the High Voltage Operations Module The aim of this module is to enable participants, through theoretical and practical training, to be prepared to operate and make safe high voltage equipment and systems, under a documented safe system of work. After having successfully completed the High Voltage Operations module, the participants will be trained in safe operations of high voltage equipment and systems. They will be ready to return to the workplace for local training within the specific SSOW and HV rules within their own workplace. Completion of this training alone does not deem participants competent to perform HV operations in the workplace. 7.2 Generic approach to High Voltage Operations training and the need for company specific development GWO High Voltage Operations training adopts a generic approach that provides a basic level of common understanding and awareness for safe HV work based on knowledge, skills and abilities within each of the lesson subjects. Lessons within this training cover highly varied regional, company and site-specific regulations, practices and procedures, with significant differences in equipment and ways of working. GWO High Voltage Operations training must be supplemented by company SSOW and site-specific training, as well as equipment-specific training in many cases. The learning objectives adopt a generic approach to support and underpin progressing to employer, site and equipment specific training.

It is always the responsibility of the duty holder to determine if a GWO training is sufficient in relation to the tasks, hazards and risks they expose a GWO trained person to, or if additional training is required.

7.3 Progression following completion of GWO High Voltage Operations Module

Completion of the GWO High Voltage Operations Module provides participants with a foundational level of knowledge, skills and ability in safe HV operations.

Following training, participants should progress to gain and record supervised workplace experience in HV operations to develop the necessary confidence and situational awareness to operate safely in controlled hazardous environments, while aligning with company and site-specific standards. Timely progression from initial training to achieving authorisation should be expected, normally within a period of 3 years. If progression to authorisation is not achieved within a timely period, then retraining needs should be considered to ensure compliance per company policy or local compliance requirements. Once sufficient workplace experience has been recorded, the duty holder should determine readiness to nominate an individual for authorisation in accordance with the company SSOW and regulatory requirements.

The determination of readiness for authorisation is the responsibility of the duty holder. Once achieving the status of a HV authorised person, it would not normally be expected to repeat this training.
