Control of Hazardous Energies Training Standard

Version 1
April 1, 2022

Hazardous energies pose a high risk of injury to all workers working within the wind industry. One of the reasons for this is that hazardous energies are found in various forms within the wind turbine environment and within the environment of a wind farm. The standard comprises of three modules:

Basic Safety CoHE

The aim of GWO’s Basic Safety CoHE training module is to enable the participants to act safely while working in the vicinity of hazardous energies in the wind industry and be able to perform assigned tasks safely.

Overall learning objective for the Basic Safety CoHE Module:

  • The participants can solve the challenge of how to act safely while working in the vicinity of hazardous energies in the wind industry and will on their own initiative seek guidance when needed (Ability, basic level)

Electrical Safety

The aim of GWO’s Electrical Safety training module is to enable the participants to support and care for themselves and others while working with, and in the vicinity of, electricity in the wind industry and to perform assigned electrical work tasks safely and efficiently.

Upon successful completion of GWO’s Electrical Safety Module, the participants will be able to perform electrical work safely within the wind industry using electrical PPE, precautionary techniques, and electrical safety safe working practices to reduce the associated risks to the electrical hazards.

Overall learning objectives for the Electrical Safety Module:

  • The participants can take responsibility for their own and others safety while working with, and in the vicinity of, electricity in the wind industry (Ability, intermediate level)
  • The participants can take responsibility for correctly completing a simple permit to work from beginning to end as the person responsible for establishing a safe work condition (Ability, intermediate level)

Note: The GWO Electrical Safety Module is aimed towards improving the participants´ ability to “work safely” with electricity. This means that the 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.

Pressure Fluid Safety

The aim of GWO’s Pressure Fluid Safety training module is to enable the participants to support and care for themselves and others while working with and in the vicinity of pressure fluids in the wind industry and to perform assigned tasks safely and efficiently.

Upon successful completion of GWO’s Pressure Fluid Safety Module, the participants will be able to reduce the associated risks to and work safely with pressure fluid tasks in the wind industry by being able to select the correct and required PPE for working with hydraulic fluids and fluids under pressure, using safe work practices and establishing a safe work condition when working with and in the vicinity of pressure fluids in the wind industry.

Overall learning objectives for the Pressure Fluid Safety Module:

  • The participants can take responsibility for their own and others safety while working with and in the vicinity of pressure fluids in the wind industry (Ability, intermediate level)
  • The participants can take responsibility for correctly completing a simple permit to work from beginning to end as the person responsible for establishing a safe work condition (Ability, intermediate level)

Note: The GWO Pressure Fluid Safety Module is aimed towards improving the participants´ ability to “work safely” with Pressure Fluids. This means that the Pressure Fluid Safety Module is not aimed at improving candidates´ technical knowledge, skills, and abilities regarding Pressure Fluids. Participants should already possess these 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.

This standard has been developed in response to the demand for recognisable Control of Hazardous Energies (CoHE) Training in the wind industry. It has been created in co-operation between members of the Global Wind Organisation (GWO) based on risk assessments, in-depth descriptions of job roles and tasks relevant to CoHE in the wind industry as well as factual incident and accident statistics pertaining to the installation, commissioning, service and maintenance of wind turbine generators and wind power plants.

This CoHE training standard describes training that complements company, turbine, regional and equipment specific CoHE trainings by providing a common basis for CoHE trainings that are recommended by the members of GWO but does not automatically qualify the participants. These nominations can only be granted according to company specific trainings, rules and procedures along with national and regional legislation.

Lastly, the members of GWO also strongly emphasise that company specific rules and procedures along with national and regional legislation shall always be looked up and followed when working in the wind industry. This is because CoHE rules, procedures and requirements can vary depending on: national and regional legislation; company approach and WTG model.
