What is CoHE?

 

Control of Hazardous Energies (CoHE) standard is the official GWO training for risk prevention in the maintenance of electrical and hydraulic systems in a wind turbine. The CoHE is aimed at workers in the wind energy sector who have to carry out activities in a wind turbine environment, especially if they have to work with electrical or hydraulic systems, whether in onshore or offshore wind farms.

CoHE standard

 

The GWO Control of Hazardous Energies standard currently consists of three modules dedicated to the standards for the use of elevators in the industry, the safety procedures to be followed before and after each use, the hazards of their use, and how to prevent them.

  • Basic Safety Module: course on the risks of using elevators inside wind turbines and how to mitigate them.
  • Electrical Safety Module: course on the risks present in the inspection and commissioning of elevators, and how to mitigate them.
  • Pressurized Fluids Safety Module: course on the risks present in the start-up, inspection, installation, and maintenance of elevators in wind turbines, how to mitigate them and how to act in a dangerous situation.

Module objectives

The CoHE Basic Safety module ensures that, upon completion, participants will be able to:

  • Solve the challenge of how to act safely while working around hazardous energies in the wind industry and will seek guidance on their own initiative when necessary.

BaSC – Basic Safety in Control of Hazardous Energies

Content: the objective of the GWO training module on CoHE Basic Safety is to enable participants to act safely when working around hazardous energies in the wind industry and to be able to perform assigned tasks safely.

Validity: 24 months

Module objectives

The CoHE Basic Safety module ensures that, upon completion, participants will be able to:

  • Solve the challenge of how to act safely while working around hazardous energies in the wind industry and will seek guidance on their own initiative when necessary.

Module objectives

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

The Electrical Safety module ensures that, upon completion, participants will be able to: 

  • Participants will be able to take responsibility for their own safety and the safety of others while working with and around electricity in the wind industry.
  • Participants will be able to take responsibility for correctly completing a simple work permit from start to finish as responsible for establishing safe working conditions.

Note: the GWO Electrical Safety Module aims to improve participants’ ability to “work safely” with electricity. This means that the Electrical Safety Module is not intended to improve candidates’ technical knowledge, skills, and abilities in relation to electricity. Participants must already possess the necessary technical knowledge, skills, and abilities prior to attending the module. Similarly, GWO CoHE is not intended to promote the acquisition of advanced knowledge, such as problem-solving.

ES – Electrical Safety

Content: the objective of the GWO training module on Electrical Safety is to enable participants to support and care for themselves and others while working with and around electricity in the wind industry, and to perform assigned electrical work tasks safely and efficiently.

Duration: 10 hours and 45 minutes

Validity: 24 months

Module objectives

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

Module objectives

Upon successful completion of the GWO Pressure Fluid Safety module, participants will be able to reduce the risks associated and work safely with pressurized fluid tasks in the wind industry, being able to select the correct PPE required for working with hydraulic fluids and pressurized fluids, using safe working practices and establishing safe working conditions when working with and around pressurized fluids in the wind industry.

The Pressure Fluid Safety module ensures that, upon completion, participants will be able to:

  • Participants can take responsibility for their own safety and the safety of others when working with and around pressurized fluids in the wind industry.
  • Participants can take responsibility for correctly completing a simple work permit from start to finish as responsible for establishing safe working conditions.

    By definition, the BST has improved the alignment and quality of safety training because we now have a standard that delivers a baseline of competence. As an owner/operator of wind turbines, we wouldn’t allow anyone to work on site without the certification.
