The additional fall protection system should be chosen in such a way that it will not hinder the exercise. Preferably this additional fall protection is not even noticeable by the participant An angle factor, in the context of lifting and rigging, is a multiplier used to account for the increased tension on slings when they are used at an angle other than vertical. It's a way to calculate the impact of the sling angle on the load being lifted A safety practice where two colleagues pair up to inspect each other’s equipment, tools, or work setup. The purpose of a buddy check is to catch any errors, oversights, or loose connections that a person might miss when inspecting their own setup.

ART V6 Change Log

Overall structure & portfolio

• Removed the Combined ART module and the stand -alone Single Rescuer modules (SR:HSIBR and SR:NTBR).

Introduced a four -module structure:

•

o ART -H and ART -N (initial) – each ~12 hours (≈1½ days)

o ART -HR and ART -NR (refresher) – each 7.5 hours (1 day).

• Removed the role of ART/ART -R in recertifying BST Working at Heights and Manual Handling; BST WAH/MH are now prerequisites only.

Single Rescuer integration

8 / 214

Safety training

G WO Advanced Rescue Training Standard / V6 02032026

Embedded Single Rescuer training directly into ART

-H and ART -N through dedicated application

•

lessons (~90 minutes each).

Embedded Single Rescuer refresher content (≥90 minutes) into ART -HR and ART -NR, with a clear expectation that each participant completes at least one full Single Rescuer scenario in both initial and refresher modules.

•

Removed all separate Single Rescuer course codes and references.

•

Rescue methods & scenario design

• Removed references to tensioned line, zip line and aerial ropeway setups from objectives, examples and instructor guidance.

• Introduced and defined cross hauling / controlled horizontal transfer, with explicit alignment to equipment manufacturer instructions for use and centre -specific risk assessment.

Re-designed HSIBR and NTBR scenarios so that:

•

o Hub/spinner/blade rescues are treated as integrated scenarios in ART

-H/H-R, and

o Evacuation from nacelle to base, enclosed -space and crawl -space rescues are combined into coherent scenario blocks in ART -N/N -R, leading into Rescue up.

Clarified that timetables define the intended sequence of lessons; only minor re

-ordering within a

•

single lesson is allowed.

Training, assessment, facilities and instructors

• Clarified training -facility expectations so that mock -ups reflect realistic spatial constraints of nacelle, hub and tower (no bypassing confined areas by walking around outside the structure) and require the use of structural or certified anchor points only.

• Strengthened guidance on use of the Participant Performance Assessment (PPA) form, including making clear to participants when they are practising and when they are being formally assessed.

• Clarified instructor expectations for packaging, head support and optional cervical collar use, requiring demonstrable skills above participant level and application of Annex 3 and manufacturer instructions.

Definitions, annexes and editorial clean -up

• Updated and aligned key definitions (e.g. Rescue, Evacuation, Cross hauling) to support consistent use across all modules.

• Rewrite of Annex 3 from a cervical -collar focus to “Head support during rescue”, reflecting current evidence and positioning collars as an optional, last -resort tool in specific contexts.

9 / 214

Safety training

G WO Advanced Rescue Training Standard / V6 02032026

• Removed references to Combined ART and stand -alone Single Rescuer modules from annexes and version history; added entries for the new four -module structure and the removal of WAH/MH recertification via ART.

• Applied general wording, numbering and layout updates for clarity and alignment with current GWO standard templates.

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 proce dures.

This standard describes the requirements for advanced rescue training courses that are

recommended by the

members of GWO. The full standard is comprised of two modules:

Hub, Spinner and Inside Blade Rescue - Initial and Refresher Training

•

Nacelle, Tower and Basement Rescue

- Initial and Refresher Training

•

This standard has been developed in response to the demand for recognisabl

e advanced res cue training in

the industry and has been prepared in co -operation between the members of GWO based on risk assessments and factual incident and accident statistics from G+ and the wind industry .

GWO members agree that everyone working on one of their

sites (wind turbine generators, sub stations, etc.)

shall complete advanced rescue training courses and subsequent company training

relevant for their

assignments. All work shall be done in teams of at least

two competent persons. Exemptions from the above

can be made based on internal company rules.

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.

Note

6. GENERA L RESOURCES REQU IRED TO DELIVER ADVANCED RESCUE TRAINING

The training provider shall ensure that staff, facilities, and equipment

meet the GWO Requirements for

Training .

6.1 Instructor prerequisites

The instructor shall possess appropriate qualifications and experience to ensure that all training and supportive activities are carried out in accordance with current legislation and current GWO training provider requirements.

All staff shall possess the appropriate competencies to conduct

or assist in the delivery of elements of

training they have been assigned to.

The instructor must be:

qualified GWO BST WAH instructor

qualified GWO BST M anual Handling instructor

3. able to apply knowledge and practical skills in alternative rescue methods, techniques, and rigging setups comparable to those executed by the participants during the practical exercises of the ART modules

6.2 Practical Training Facilities

All facilities shall be maintained and, where appropriate, inspected and tested in accordance with current national legislation and manufacturer recommendations. Risk assessments shall be conducted and documented for all training facilities , and t he training provider shall hold the required permits to operate the facilities. between the training environment and the working environment. Comparable elements enhance the practical application of what is learned. The practical training facilities and the training environment are therefore expected to incorporate as many identical or comparable elements to a real wind turbine working environment as possible. The learning process is facilitated by identical or comparable elements

14 / 214

Safety training

G WO Advanced Rescue Training Standard / V6 02032026

The objective is that the practical training facility

enable s each participant , individually or as part of a team,

to see, hear, and practi se the subject matter in a way that resembles working practi

ces in a real wind turbine

environment.

The design of training facilities shall also take into account the increasing size of modern wind turbine generators. Many existing mock -ups are based on earlier, smaller turbine types; training providers shall verify that the dimensions and configurations of their mock -ups (for example hub and nacelle length, vertical travel distances and horizontal movements with a stretcher) reasonably reflect the turbine types and sites for which the training is delivered. Any significant limitations shall be described in the training provider’s documentation and risk assessment. The following training facility items are required for the ART training:

Mock-up with enclosed space to simulate the hub,

including a height differentiated crawl way

a. figure 6 .2.1 provides dimensions for the GWO recommended hub mock -up

b. the training provider may deviate from the recommended hub measurements to

reflect a specific

turbine design

2. Mock-up to simulate access between hub and blade with a maximum access hatch diameter of 0.6

a. the diameter may be reduced to 0.50 m to simulate a pitch cylinder partly blocking the hatch

Mock-up for “rescue up” exercises, to simulate basement

and tower rescue

4. Mock-up to simulate the area under the gearbox with a max imum 0.6m diameter crawl way into the crawl space, height between 0.6 m and 0.3 m, and a minimum length of 2.0 m

Mock-up to simulate the nacelle

a. figure 6 .2.2 provides dimensions for the GWO recommended nacelle mock -up

b. the training provider may deviate from the recommended nacelle measure ments to reflect a specific turbine design

c. the nacelle mock -up must contain sufficient simulated assets to create a realistic nacelle environment

shall be less than 3.0 m 2 , excluding walkways of less

the maximum available contiguous floor space

than 0.6 m width

e. the sides of the nacelle should be designed to prevent direct visual contact from within the nacelle to teams outside of the nacelle

f. all anchor points used for fall protection and rescue in the training facility shall be structural or certified anchor devices, installed and verified by a competent person and rated for the maximum expected loads in accordance with relevant standards (e.g . EN 795 or local equivalent). Decorative or non -structural mock -up anchor points shall not be used for attaching PFPE or rescue systems.

15 / 214

Safety training

G WO Advanced Rescue Training Standard / V6 02032026

Connecting the various mock -ups should create a realistic training sequence. For example, connecting the nacelle mock -up with the hub mock -up provides a more realistic scenario than connecting a blade mock -up with the nacelle mock -up. If there are practical reasons to separate the individual mock -ups, this is acceptable , for example, to allow several teams to train at the same time. Participant movement and training activities shall reflect the spatial limitations of a real nacelle or hub. Training areas shall simulate restricted space and avoid open areas that allow free movement or access around the outside of the mock -up. Participa nts shall not be able to reach or enter the hub/nacelle by walking or operating on the outside of the mock -up instead of using the intended internal access routes.

Figure 6.2.2 – Recommended dimensions for the nacelle mock -up

6.3 Wind Turbine Environment Explained

The training providers ‘goal should be to achieve training facilities and a training environment with as many identical elements to a real wind turbine working environment possible. In addition, ‘train as you work’ (e.g. executing training end to end the way participants should perform in practice ) enhances real work behaviour.

So how can training be designed

to ‘train as you work’ and create an e nvironment with a high degree of

realism?

For access up and down the tower, the tower is typically fitted with ladder sections equipped with a vertical fall protection system and tower section platforms with ladder hatches that include certified anchor points for attaching personal fall protection equipment. The wind turbine may also include a basement section fitted as mentioned, primarily holding electrical cabinets. In the geared type WTG s, access in the nacelle is in general limited to narrow pathways along the left or right side of the main shaft and generator . These pathways often contain mechanical components, as well as steps and small ladder sections due to variations in floor level, increasing the risk of trips and falls. Access between the nacelle and hub is possible through low and often very narrow passageways.

17 / 214

Safety training

G WO Advanced Rescue Training Standard / V6 02032026

‘Train as you work ’ training should be carried out by doing real work tasks end to end following actual working procedures, and realistic emergency situation s (e.g. fire, first aid, rescue, evacuation or injured person rescue) in a wind turbine environment.

6.4 Training Equipment

The equipment required for training, as listed in Annex 1, must be available and must meet the national legal requirements specified in Table A 1.1 in Annex 1 .

A generic approach to teaching safety equipment is applied

in this module to avoid potential product

specific additional training

after completion, which may be required by the participant’s organisation

(e.g.

prior to site work ).

The generic approach is achieved by teaching a variety of safety equipment products within each category (e.g. guided type fall arresters). This enables participants to c arry out pre-use inspection s and operate other safety equipment products beyond those demonstrated du ring this module , provided they refer to the manufacturer’s user manual. However, a location specific risk assessment may identify the need for additional instructions.

Additional fall protection must always be used during training activities at height.

It must be ensured that equipment combinations and training activities do not compromise the function of the additional fall protection system. Systems used as backup elements must be risk assessed as suitable for that purpose.

Note

The training provider shall introduce control measures that lower the risks and hazards associated with a fall from height to an acceptable level, following the Hierarchy of Controls in their risk assessment.

GWO recommends a maximum fall factor of 0.5.

To calculate this , the following formula is applied, based on

the maximum allowed lanyard of length 2.00 m and a fall of 1.00 m.

𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 𝐹𝑎𝑙𝑙𝑒𝑛 𝐿𝑒𝑛𝑔𝑡ℎ 𝑜𝑓 𝑙𝑎𝑛𝑦𝑎𝑟𝑑

𝐹𝑎𝑙𝑙 𝐹𝑎𝑐𝑡𝑜𝑟 (𝐹𝐹) =

1.00 𝑚 2.00 𝑚

During the rescue a nd evacuation exercises in this module the anchor points used for the attachment of fall arrest lanyards (including energy absorbers) must be positioned high enough above the ground (or structure below) to ensure that, in the event of a fall, the energy absor ber can fully deploy and prevent the participant from contacting the ground (or structure directly below the anchor point).

During the rescue exercise participants must be able to experience a minimum amount of descent (using an evacuation or rescue device) to ensure they gain the experience of the speed of descent when using these

devices. This can be achieved by having the participants descend from a minimum height using a rescue or evacuation device.

To ensure enough clearance below the anchor point, for all fall protection equipment that may be used, and to ensure participants can experience a descent of sufficient duration for meaningful learning transfer, GWO recommends that the anchor point is at l east 6.75 m above the ground (or above the structure directly beneath the anchor point). The rationale for this clearance is explained in detail in Annex 1.

If a training provider chooses to use an anchor point lower than the recommended 6.75 m, the following additional control measures must be in place.

a. a documented risk assessment for the lower height, including calculations for the equipment used during the rescue or evacuation exercises. The calculations shall:

a.i use energy absorber elongation value provided by the equipment manufacturer

a.ii demonstrate that the equipment will prevent the person from contacting the ground or structure directly below the anchor point

a.iii use a formula provided by the equipment manufacturer or national legislation for calculating anchor point clearance height; where no such formula exists, use the formula in Annex 1.

the potential fall factor shall not exceed 0.5

c. participants must experience a descent from a platform that is a minimum of 4.5 m above the ground

7. USING THIS STANDARD TO DEVELOP TRAINING

If you have questions about this standard you can access support and read answers to FAQs in the: GWO Help Centre.

Note

The training in this standard is designed around the GWO taxonomy described in the GWO Requirements for Training . Theoretical and practical activities must be delivered according to the defined taxonomic level to reach the described learning objectives. When teaching safety equipment , a generic approach shall be applied aiming to avoid additional potential product specific formal training after completion of this training. However, national legislation, company gap analysis and location specific risk assessments may require additional product specific familiarisa tion which is the responsibility of the duty holder.

In addition to this, all training based on this standard including all related resources shall, as a minimum, meet the requirements described in the GWO Requirements for Training .

8. ADMINISTRATION AND CERTIFICATION OF REFRESHER TRAINING

8.1 Course Participant Performance Assessment

Participants will be evaluated through direct observation of practical exercises and supplementary oral questions, using the GWO Participant Performance Assessment (PPA) form. Instructors shall apply the defined performance criteria and critical errors con sistently for all participants to support inter -rater reliability. At the start of the course, and before each assessed scenario, participants shall be informed which activities are for practice and feedback only and which activities contribute to the form al assessment of their performance. Throughout the course the instructor will adhere to the course participant performance assessment form (see the Requirements for Training) with a high focus on evaluating the participants’ practical skills.

The course participant performance assessment form is a final evaluation tool for the instructors to assess participants during practical elements.

9. HUB , SPI NN ER AND INSIDE BLADE RESCUE INITIAL TRAINING

9.1 Aims and objectives for the

Hub, Spinner and Inside Blade Rescue Initial Training

The aim of this module is to , through theoretical and practical train ing, to perform rescue operations, in a WTG hub, spinner and inside the blade by using industry standard rescue equipment, methods and techniques, exceeding those of GWO Working at Height . provide participants with the knowledge, skills and abilities

After having successfully complete d this module, the participants will be able to demonstrate that they can:

1) Take responsibility to determine rescue and evacuation strategy, performing rescue operations in a WTG hub, spinner and inside the blade (Knowledge, intermediate level)

2) Apply clear communication and guidance to other emergency responders (e.g. vessel or ambulance crew) including coordinating the handover of an injured person (Skills, intermediate level)

3) Perform descending rescue operations in teams acting as the rescue team coordinator from a WTG hub, spinner and from inside a blade, to a primary assembly area (ground or transition piece) or a secondary assembly area (vessel), using industry standard rescue equi pment (Skills, Intermediate level) 4) Assess and determine single rescuer rescue strategy (relevant rescue method, technique, certified equipment, and how to organise the rescue efforts and incident scene) for selected rescue scenarios in a WTG hub, spinner and inside a blade (Knowledge, intermediat e level).

Rescue operations performed on the outside of the blades are not included
