Term

Definition

Approach boundaries

Limited Approach Boundary

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.

Approved work instruction

Normally done with its corresponding Risk Assessment that will include the control measures for all risks identified.

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.

4 / 55

Safety training

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

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

When?

Whenever someone is required to enter the Limited Approach Boundary to do other tasks different than ‘visual inspection’ and whenever someone needs to enter the Restricted Approach Boundary for other tasks different from ‘switching’ or ‘measuring’

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verify that all contact points of the disconnecting devices are fully open, or that draw-out type circuit breakers are withdrawn to the fully disconnected position. 4) To mitigate for activation spring failure in circuit breakers equipped with spring activation, the spring must be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

The terms and definitions in the GWO CoHE Refresher Standard were made for the sake of creating this global training standard based on the common ground of different recognised standards. Participants could end up working under any variety of safe system of work, so the language and terminology have been chosen to be as applicable as possible across the most common systems of work.

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 Refresher Standard describes refresher 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 Refresher

CoHE Electrical Safety Refresher

9 / 55

Safety training

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

CoHE Pressure Fluid Safety Refresher

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) refresher 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 REFRESHER STANDARD

7.1 Target Group

Target Group for the CoHE Basic Safety Refresher 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 Electrical Safety Refresher 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 voltage1 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), Authorised Technician (WTSR), to enable others to work safely on low voltage electrical systems.

The GWO Electrical Safety Refresher Module and Pressure Fluid Safety Refresher 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 the two modules) to promote the acquisition of advanced knowledge, such as troubleshooting.

Note

Target Group for the Pressure Fluid Safety Refresher Module This module is targeted at candidates whose scope of work will involve performing isolations and testing for the absence of pressure (in accordance with existing documentation) to be able to safely carry out specific tasks like component replacement, servicing and planned corrective maintenance on pressure fluid systems. Additionally, this person will also be responsible for establishing a safe work condition to enable others to work safely on pressure fluid systems.

Also, it is strongly recommended that before attending the CoHE Pressure Fluid Safety Refresher Module, participants have some applicable working experience with pressure fluids supervised by a Qualified Person.

7.7 Physical demands

All personnel participating must meet the participant prerequisites described in the GWO Requirements for Training.

7.8 Design of the Activities in the CoHE Refresher Standard After the introduction in all three modules, the suggested design of the activities in the CoHE Refresher Standard is to start each of the three modules with challenging, realistic assessment activities for the participants i.e. most likely scenarios that require the participants to make the same decisions and take the same actions as the participants would need to do on the job and to meet the learning objectives. This will allow the instructor to assess each participants ability to meet key learning objectives from the original CoHE Training Standard such as establishing a safe working condition in multiple pressure fluid situations or scenarios from a WTG environment (e.g. “show me how to establish a safe working condition here” in simple to very difficult scenarios) By assessing each individual participant ability level, it will be possible for the instructor to provide additional focused and specific learning activities for the participants, who show a gap between their abilities and the desired learning objectives of the CoHE Refresher Standard. These focused and specific learning activities are meant to improve these participants´ performance and should be facilitated for the participants until they have closed this gap and have reached the learning objectives of the CoHE Refresher Standard. Examples of the learning activities could be worked examples demonstrated by the instructor followed by guided and independent practice activities with feedback for the participants. Participants, who in the assessment activities demonstrate and are assessed by the instructor to have achieved the learning objectives of the CoHE Refresher Standard, can complete the training at this point i.e., are not required to spend any more time or receive any additional specific training unless the participants are interested in learning more. This means that all participants will be enabled to reach all the learning objectives according to their individual ability level while ensuring that already fully capable participants spend the minimum amount of time engaging in training in what they can already do. In addition, through this design, the refresher trainings will focus more on application as opposed to just information which makes the training more active and less passive for the participants.

The flow of assessment activities could look like this:

13 / 55

Safety training

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

Suggested steps before the refresher training:

1. Create challenging, realistic assessment activities that are increasingly challenging for the participants e.g. scenarios. The activities should ask participants to make the required decisions and take the required actions that they need to make to reach the learning objectives. a. Within each assessment activity, it would be beneficial for the participants to have the possibility of failing (catastrophically) and be sent back to the start of that activity to try again. This allows reinforcement and practice until the participants can reach the learning objectives.

2. Identify the minimum information that participants need to know to complete those activities

3. Make that information available as an optional link or resource in the activities. Let people pull the information when they need it

4. Prepare specific, focused learning activities such as worked examples and more practice opportunities in the case that a participant shows a gap between the abilities and the desired learning objectives of the CoHE Refresher Standard During CoHE Refresher Modules training: 1. Facilitate the created challenging, realistic assessment activities for the participants e.g. scenarios: a. If a participant makes all the correct decisions and take all the right actions regarding, e.g. which safe working practices to use and decide on all the right and realistic actions without any guidance or support, the participants should be able to complete the refresher in the approx. time duration or in less time

14 / 55

Safety training

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

b. Optional information and guidance should again always be available as a link or resource, so if a participant is interested in learning more, they can pull the material to them.

2. Once participants make their decision and act, consider showing the necessary information in the feedback i.e. first show the consequence of their choices and actions (e.g. what would happen if the participant failed to identify and avoid a safety hazard). Then show the information that the participant should have used, thought about, or looked at. 3. If a participant does not demonstrate the needed abilities or do not reach the learning objective(s), makes mistakes or needs guidance to correctly complete an activity, the participant should be provided with individual, specific, and focused learning activities to improve their performance and reach the learning objectives. These individual focused and specific additional learning activities should be provided to these participants until they have reached the learning objectives of the CoHE Refresher Standard. Examples of these individual focused and specific additional learning activities could be worked examples demonstrated by the instructor followed by more guided and independent practice for the participants to enable the participant to improve and reach the learning objectives. These additional, individual learning activities will very likely lead to additional contact time for the participant than what is listed in the approx. time duration in the CoHE Refresher Standard.

Repeat as needed.

7.9 Instructor Qualification Prerequisites

A competent GWO CoHE Refresher instructor must adhere to the instructor in GWO’s Requirements for Training.

11. MODULE 2- COHE ELECTRICAL SAFETY REFRESHER

11.1 Aims and objectives of the CoHE Electrical Safety Refresher Module The aim of GWO’s CoHE Electrical Safety Refresher Module training 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 tasks safely and efficiently. Upon successful completion of GWO’s CoHE Electrical Safety Refresher Module training, 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 electrical hazards.

Overall learning objectives for the CoHE Electrical Safety Refresher Module:

1) Take responsibility for their own and others safety while working with, and in the vicinity of, electricity in the wind industry (Ability, intermediate level)

2) 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)

The GWO CoHE Electrical Safety Refresher Module is aimed towards improving the participants´ ability to “work safely” with electricity. This means that the Electrical Safety Refresher 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 Refresher standard to promote the acquisition of advanced knowledge, such as troubleshooting.
