Deranged equipment Equipment that is suspected to be damaged and must be treated with more caution than equipment in its normal condition

Electrical work (definition and examples)

Any task performed on an electrical installation that requires specific electrical knowledge to be performed safely and correctly Examples: install components, alter a circuit, take electrical measurements, replace a component, create an electrically safe work condition etc. When? Whenever someone is required to enter the Limited Approach Boundary to do tasks other than visual inspection and whenever someone needs to enter the Restricted Approach Boundary for tasks other than "switching" or "measuring"

Establishing an electrically safe work condition (when and how to establish.)

How?

1) Determine all possible sources of electrical supply to the specific equipment. Check applicable up-to-date drawings, diagrams, and identification tags 2) After properly interrupting the load current, open the disconnecting device(s) for each source 3) Whenever possible, visually verify that all contact points of the disconnected devices are fully open, or that draw-out type circuit breakers are withdrawn to the disconnected position 4) To mitigate for activation spring failure in circuit breakers equipped with spring activation, the spring must be released prior to opening the breaker or prior to using the breaker as the isolation point 5) Where the possibility of stored electrical energy exists, this must be isolated or insulated. Where this is not possible the energy must be dissipated by using an approved tool rated and designed for the purpose

6) Verify absence of voltage to verify that the circuit parts are de-energised

7) For low voltage circuits with the possibility of induced voltage, apply short- circuiting earth connections rated for the fault current 8) Apply lockout/tagout devices in accordance with the local legislation and specific company procedure and rules. Depending on the configuration of the circuit it may be necessary to perform this step prior to steps five - seven Electrical components or parts capable of being inadvertently touched or approached nearer than a safe distance by a person that is by not being enclosed or insulated (e.g. IP0X, IP1X)

Exposed electrical parts

Hazardous energy

Any energy (electrical, mechanical, hydraulic, pneumatic, chemical, thermal, gravitational force etc.) that could cause injuries to personnel

Control of Hazardous Energies Standard / V5 DRAFT REVIEW - Oct 2025

High Voltage

In this GWO training standard, the term High Voltage is used for voltages normally exceeding low voltage. The exact voltage designation varies globally depending on where you work.

Use of the term High Voltage:

Terms for low, medium and high voltage may be applied in different ways in different geographies and in other working contexts, such as at the electrical distribution and transmission network levels. For example, IEC defines high voltage as a voltage which exceeds 1000 V AC or 1500 V DC., while NFPA 70E and OSHA defines on or above 600V as high voltage working. At the electrical network level, IEC defines high voltage lines as those above 36 kV (36,000 volts), while medium voltage lines are networks with a voltage between 1 and 35 kV (1,000 and 35,000 volts).

Isolation point

An isolation device shall ensure a reliable disconnection or separation from an energy source

In this GWO training standard, the term low voltage is used to refer to voltages less than those defined as high voltage. The exact voltage designation varies globally depending on where you work.

Low voltage

Use of voltage classifications:

IEC defines LV as voltages normally exceeding 50 V AC or 120 V DC but not exceeding 1000 V AC or 1500 V DC between conductors, or 600 V AC or 900 V DC between conductors and earth. According to the ANSI C84.1-2020: low voltage is between 240 to 600 V and medium voltage is 2.4 to 69kV.

Energy source where you know the level of energy (e.g., as part of a circuit, socket, or a hydraulic check/test point)

Live known source

Minimum arc flash PPE

Minimum:

safety glasses

•

• non-melting clothing (including underwear) with long sleeves and long trousers (small parts of melting materials are acceptable but should be reduced to the minimum possible, ideally eliminated, for example elasticated waistbands) • Safety shoes with non-melting materials (acceptable exceptions are the sole and shoelaces)

Pressure fluids

Compressible (e.g., nitrogen) and non-compressible (e.g., hydraulics) fluids under pressure

Pre-task or job briefing (toolbox talk)

Before starting each job, the employee in charge of the job must conduct a job briefing with the employees involved. The briefing must cover such subjects as:

6 / 79

Safety training

Control of Hazardous Energies Standard / V5 DRAFT REVIEW - Oct 2025

hazards related to the job

•

work procedures involved

•

special precautions

•

energy source controls

•

• personal protective equipment requirements

Safe handling of batteries and capacitors

a) always visually inspect the batteries and capacitors before starting work; look for signs of distress and leakage b) take precautions to guard battery terminals against short circuiting by covering the terminals with insulating tape or insulating mats

c) ensure all batteries and capacitors are correctly and securely mounted

d) ensure the batteries and capacitors are wired with the correct polarity as per the wiring diagrams and that all terminals are tight e) defective batteries and capacitors must be disposed of in accordance with local legislation f) insulated tools approved for the rated voltage must be used when working around live, exposed conductors

Test point

Point used to measure energy

The qualification requirements for working on high voltage systems

Qualified Electrical Person with specific training in the job and experience in high voltage

The requirements for tools to be used for testing for the absence of voltage

Have limited functionality and be with fixed test leads Or; Be multi-meters with an audible alert function to warn the user in the event the meter function selector and test leads positions are not compatible Test probes must be selected to match the physical requirements of the test point and be in accordance with local electrical regulatory requirements. Non-contact voltage detectors are for use only with non-contact voltage portals or for double checking that the lockout boundary is in electrically safe work condition. Non-contact voltage detectors are not allowed for ‘test-before-touch’ verification Mandatory when performing energised work (in extraordinary circumstances under an approved special permit) that requires using the tools inside the Limited Approach Boundary or Restricted Approach boundary

When to use insulated (voltage-rated), approved tools?

Worked example

A worked example is a step-by-step demonstration of how to best perform a task or solve a problem. These include a starting point, a desired goal state, and a chosen solution to reach the goal state. They manage cognitive load by focusing on critical aspects of the solution steps and the solution. It is important to use a less is more approach and include only what participants need to understand the solution. Adding extra and ‘nice to know’ information or content makes it more difficult for participants to understand For more information, please visit: https://3starlearningexperiences.wordpress.com/2018/11/13/why-and-how-to-use- worked-examples-in-the-workplace/

4. SCOPE

Global Wind Organisation is a non-profit body founded by the wind turbine manufacturers and owners. Our members strive for an injury free work environment in the wind turbine industry, setting common international standards for safety training and emergency procedures. Training is verified through GWO’s WINDA database.

Hazardous energies are found in various forms within the wind turbine and the environment of a wind farm, posing a high risk of injury to all workers within the wind industry.

The GWO Control of Hazardous Energies (CoHE) training standard has been developed in response to the demand for recognisable CoHE training for the wind industry and has been prepared in co-operation between the members of GWO based on Safe Systems of Work (SSOW), risk assessments, job roles and tasks relevant to CoHE in the wind industry, as well as factual incident and accident statistics from G+ and the wind industry. This training is recommended by the members of GWO to support company, turbine, regional and equipment specific training and it must be supplemented by further company SSOW and site- specific training.

Completion of GWO CoHE training provides participants with foundational knowledge, skills and ability in the safe control of hazardous energies.

The standard comprises of two modules:

CoHE Electrical Safety Module

CoHE Pressure Fluid Safety Module

The GWO CoHE training standard adopts a generic approach to training for work with highly varied regional, company and site-specific regulations, practices and procedures, with significant differences in equipment and ways of working. The learning objectives adopt a generic approach to support and underpin progressing to employer, site and equipment specific training. GWO CoHE training must be supplemented by company SSOW and site-specific training, as well as equipment-specific training in many cases.

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.

General feedback on this document can be sent to info@globalwindsafety.org. See globalwindsafety.org on how to raise a complaint about a training provider or report a safety incident occurring during training.
