Term

Definition

Approach boundaries

Limited Approach Boundary This is the closest distance that an Ordinary Electrical Person can approach exposed energised conductors without escort. An Ordinary Electrical Person may be escorted within the Limited Approach Boundary by a Qualified Electrical Person but may never enter the Restricted Approach Boundary. All persons in the Limited Approach Boundary must wear the minimum PPE for electrical work. All tools that enter the Limited Approach Boundary must be insulated for the equipment’s voltage. Restricted Approach Boundary The Restricted Approach Boundary may only be entered by a Qualified Electrical Person. All parts of the Qualified Electrical Person that enter the Restricted Approach Boundary must be insulated from the equipment’s voltage. An Energised Electrical Work Permit is required to enter the Restricted Approach Boundary, unless performing switching or taking measurements. Work instruction approved by the company responsible for the work described, according to its internal processes. Normally done with its corresponding risk assessment that will include the control measures for all risks identified.

Approved work instruction

Deranged equipment

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

5 / 143

Safety training

Control of Hazardous Energies Standard / V3 2023-12-04

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verify that all contact points of the disconnected devices are fully open, or that draw-out type circuit breakers are withdrawn to the disconnected position 4) To mitigate for activation spring failure in circuit breakers equipped with spring activation, the spring must be released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.

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

Live known source

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

6 / 143

Safety training

Control of Hazardous Energies Standard / V3 2023-12-04

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:

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.

7 / 143

Safety training

Control of Hazardous Energies Standard / V3 2023-12-04

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. 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.

Note

6. 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. 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. 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.

The standard comprises of three modules:

CoHE Basic Safety Module

CoHE Electrical Safety Module

12 / 143

Safety training

Control of Hazardous Energies Standard / V3 2023-12-04

CoHE Pressure Fluid Safety Module

Training is verified through GWO’s WINDA database.

This standard has been developed in response to the demand for recognisable Control of Hazardous Energies (CoHE) training in the industry and has been prepared in co-operation between the members of 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 from G+ and the wind industry.

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.

7. GENERAL REQUIREMENTS FOR THE GWO COHE MODULES

7.1 Overview

The GWO CoHE Training standard is divided into the following 3 modules:

Module 1: CoHE Basic Safety Module 2: CoHE Electrical Safety Module 3: CoHE Pressure Fluid Safety

7.2 Target Group

Target Group for the CoHE Basic Safety Module This module is targeted at candidates working in the wind industry where they are exposed to the risk of injury related to hazardous energies. Target Group for the CoHE Electrical Safety Module This module is targeted at candidates whose scope of work will involve performing isolations and testing for the absence of voltage (in accordance with existing documentation) to be able to safely carry out specific tasks like component replacement, servicing and planned corrective maintenance on low voltage 1 electrical systems. Additionally, this person will also be responsible for establishing an electrically safe work condition, as e.g. a Qualified Electrical Person (NFPA 70E), Electrical Skilled Person (EN50110), Authorized Technician (WTSR), to enable others to work safely on low voltage electrical systems.

Note

The GWO CoHE Electrical Safety Module and Pressure Fluid Safety Module are aimed towards improving the candidates´ ability to “work safely” with electricity and fluids under pressure. This means that the two modules are not aimed at improving candidates´ technical knowledge, skills and abilities regarding electricity or pressure fluid systems. Candidates should already possess these technical knowledge, skills, and abilities before attending the modules. Similarly, it is not the intention of the GWO CoHE Standard (or these two modules) to promote the acquisition of advanced knowledge, such as troubleshooting.
