2 T ERMS AND DEFINITIONS
Term
Definition
Hazardous Energy
Any energy (electrical, mechanical, hydraulic, pneumatic, chemical, thermal, gravitational force…) that could cause injuries to personnel 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… Qualified Electrical Person with specific training in the job and experience in high voltage 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. Before starting each job, the employee in charge of the job must conduct a job briefing with the employees involved. The briefing
Electrical work (definition and examples)
The qualification requirements for working on High Voltage systems
Approved work instruction
Pre-task or job briefing (toolbox talk)
must cover such subjects as: - hazards related to the job - work procedures involved - special precautions - energy source controls - personal protective equipment requirements

GWO CoHE TRAINING STANDARD V0
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verify that all contact points of the disconnecting devices are fully open, or that draw-out type circuit breakers are withdrawn to the fully disconnected position. 4.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 deenergised. 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 5 through 7. 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

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.
Minimum arc flash PPE
Minimum: - Safety glasses
- Non-melting clothing (including underwear) with long sleeves and long pants (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)
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?

6 S COPE
Global Wind Organisation is a non-profit body founded by 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. GWO training standards describe the requirements for training courses that are recommended by members of GWO. 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. Therefore, this standard has been developed in response to the demand for recognizable Control of Hazardous Energies (CoHE) Training in the wind industry and 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 and 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.
The standard comprises of three modules:
Basic Safety CoHE.
•
Electrical Safety.
•
Pressure Fluid Safety.
•
Training is verified through GWO’s WINDA database.
This standard has been developed by the GWO Training Committee. Disputes and potential non- conformities should be brought to the attention of the GWO Audit and Compliance Committee.

7 G ENERAL R EQUIREMENT TO GWO C O HE M ODULES
7.1 Overview
The GWO CoHE Training standard is divided into the following three modules:
Basic Safety CoHE.
Electrical Safety.
Pressure Fluid Safety.
7.2 Target groups
Target Group for the Basic Safety CoHE 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 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. an 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 Electrical Safety Module and Pressure Fluid Safety Module are aimed towards improving the 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.
Target Group for the Pressure Fluid Safety 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.

9 U NDERSTANDING GWO L EARNING O BJECTIVES AND T AXONOMY
9.1 Learning objectives
Learning objectives describe what the participant should know and be able to do when the training is completed. The learning objectives in a training are based on the mitigating precautions analysed in the risk assessment. They are the foundation of the learning activities, the course contents and what the participant performance assessment must be based upon.
Coherence between the learning objectives , the learning activities and the assessment is essential.
The purpose of this alignment is twofold:
1. To conduct learning activities that are directly focused on reaching the learning objectives. 2. That assessment of how well the learning objectives are met is done in close coherence with what the participant has practiced during the learning activities and in a comparable environment .
Figure 7-1 Alignment figure
Defining learning objectives in relation to all training elements ensures the alignment between objectives, activities and on-going participants assessment. More guidance about learning activities and evaluation can be found in the GWO Taxonomy Framework. To be able to focus training on building up the necessary abilities, the learning objectives are described according to the GWO taxonomy in the three domains: Knowledge, Skills and Ability. Ability is what is performed and presented during real-life exercises as well as in the real work situation and is the sum of personal experiences, knowledge, skills and attitudes.
Global Wind Organisation
www.globalwindsafety.org
19 / 142
GWO CoHE TRAINING STANDARD V0
9.2 The GWO Taxonomy Framework
The structure of the GWO Taxonomy is based on the three learning domains: Knowledge, Skills, and Ability. Learning objectives are also defined at three taxonomic levels: 1) Basic, 2) Intermediate, and 3) Advanced level. The taxonomy levels in the learning objectives are defined by a reasonable number of precise and explained action verbs (highlighted below). These action verbs are presented in a progression of increasing complexity – beginning on the basic level, where the participant can name, recognise or describe a tool or a procedure, and ending at the advanced level, where the participant can act responsibly, evaluate performance, assess decisions and supervise fellow workers. The taxonomy and the presentation of action verbs in the progressive order imply that the previous taxonomic competences are already achieved. Learning objectives in this standard are followed by an indication of the domain and taxonomy level in brackets (e.g. Skills, intermediate level). The taxonomic domains and levels are presented in the figure below.
Knowledge
Skills
Ability
The participants understand a topic in a holistic way, where risks, advantages and disadvantages are considered and form the background for reflected assessments or decisions for action. Action verbs are: Assess , explore and choose . The participants can explain how things are done and how a piece of equipment or a tool is used. The participants can discuss a matter in professional terms and language .
The participants can experiment and refine their skills as well as select and evaluate on the performance and reactions in relevant situations.
The participants can adapt and act responsibly in new ways, pay attention to the safety of fellow workers and propose development of safety procedures.
The participants can supervise or manage colleagues’ work effort.
The participants can perform a given task, apply safety procedures or a tool, and distinguish between relevant and less relevant situations in which to apply a skill.
The participants can act independently, are able to identify connections and risks in work-related situations and can take initiative and take responsibility for feasible mitigating actions on the job.
Global Wind Organisation
www.globalwindsafety.org
20 / 142
GWO CoHE TRAINING STANDARD V0
The participants can describe a topic, name its constituent parts or simply recognise it. Basic knowledge is observed by a one-dimensional objective: “I can tell a fact”.
The participants can copy and repeat a procedure or an action, that has been presented.
The participants can act independently or under supervision in familiar work situations.
Action verbs are: Show interest and solve.
Figure 2, The GWO Taxonomy – condensed (from the GWO Taxonomy)
9.3 Summing up on the learning objectives
A specific action verb indicates a taxonomic level that specifies learning activities for the participant to reach the decided learning objectives. During the learning activity the participant shall practise doing what the action verb indicates. In addition, the participant’s ability to meet the learning objectives may be evaluate by the i nstructor comparing the participant’s performance in action (as well as the evaluation at the end of a module or a training) against the action verbs and the learning objective.

10 A DMINISTRATION AND C ERTIFICATION OF M ODULES
10.1 Participant Performance Assessment
The participants will be assessed separately on each module according to the learning objectives, by means of direct observation and supplementary oral questions where appropriate (formative evaluation). Throughout each of the CoHE modules, the instructor will use the participant performance assessment form (see annex 1 of the Requirements for Trainin g Providers) to evaluate the participant’s knowledge and skills, with a high focus on evaluating the participant’s safety awareness. The instructor shall keep a participant performance assessment form (or adaptation) for each participant until the completion/evaluation of each CoHE training module. The participant performance assessment form (or adaptation) is a final evaluation tool for instructors to assess participants during practical elements. It allows measurement of the number of violations regarding safety, competency or attitude. The participant performance assessment form shall be used as a progressive evaluation tool to discuss the performance of a participant in guiding them to success. It also serves as supporting documentation if a participant passes or fails the module.
Training providers may adapt the participant performance assessment form to other media.
Training providers must have a documented procedure in place for dealing with participants not meeting the stated learning outcomes.
