Term

Definition

Active Setup

Rescue device in inverted/reverse mode setup, i.e. the rescue device attached to the injured person (and the rescue device rope’s loaded end is rigged in the WTG) Describes the use of an independent, additional suitable fall protection system in conjunction with a primary fall protection system. Typically, used during training to provide fall protection to participants as they learn to use fall protection equipment. Additional fall protection may sometimes be referred to as a “backup”.

(Rescue device in stationary mode setup)

Additional fall protection

5 / 181

Safety training

GWO Advanced Rescue Training Standard / V4 2023-05-02

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. This means that a risk is identified and controlled to a lower level weighted against the effort, time and money needed to control it

As low as reasonably practicable

Clear / precise communication

technician A is giving information to technician B

technician B repeats the information

technician A confirms that the repetition is correct

if repetition was not correct the technician starts at “a” again.

Preventing the user of a personal fall protection system from colliding with the ground, structure, or any other obstacle during a free fall Personal fall protection system which limits the impact force on the body of the user during fall arrest Preventing the user of a personal fall protection system from going into a free fall The time that must be utilised in the course, either theory or practical elements, where training provider sees the most valuable for the participants As opposed to product specific training, a generic approach to teaching safety equipment focuses on the similarities and differences in design, functionality and operation between different equipment products. The generic approach is achieved by teaching a variety of rescue equipment products within each rescue equipment category (e.g. rescue stretchers) enabling the participant to conduct pre-use inspection and to use other rescue equipment products compared to those taught during this Module (based on the manufacturer’s user manual) but without additional formal training. Consequently, a potential task is placed upon the participant on course completion, requiring them to familiarise themselves with other rescue equipment products in their own organisation e.g. prior to site or work, based on the manufacturer’s user manual. A technique used during the rescue of a casualty from a ladder where the rescue line is diverted using the side D-ring located at the hip of the rescuer’s harness. This creates greater space between the casualty and the ladder

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. This standard describes the requirements for advanced rescue training courses that are recommended by the members of GWO. The full standard comprises of four modules:

Hub, Spinner and Inside Blade Rescue (HSIBR)

Nacelle, Tower and Basement Rescue (NTBR)

Single Rescuer: Hub, Spinner and Inside Blade Rescue (SR:HSIBR)

Single Rescuer: Nacelle, Tower and Basement Rescue (SR:NTBR)

This standard has been developed in response to the demand for recognisable advanced rescue 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 properties (wind turbine generators, sub stations, etc.) shall complete advanced rescue training courses 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. 5. GENERAL REQUIREMENTS FOR THE ADVANCED RESCUE TRAINING Upon completion of the Advance Rescue Training Standard, participants will be able to access and rescue an injured person from the hub and the nacelle, tower, and basement section of a wind turbine. These training modules can be delivered independently of one another or as stand-alone training. 5.1 Overview The GWO Advanced Rescue Training is divided into the following four modules:

Module 1:

Hub, Spinner and Inside Blade Rescue (HSIBR)

Module 2:

Nacelle, Tower, and Basement Rescue (NTBR)

Module 3:

Single Rescuer: Hub, Spinner and Inside Blade Rescue (SR:HSIBR)

Module 4:

The total training day includes contact time, meals and breaks and travel between training sites (where applicable).

If a participant fails to meet the demands of an Advanced Rescue Training module, they shall attend a new Advanced Rescue Training module. 5.5 Guidance on delivering lesson elements The delivery of this module must comply with the requirements described in the GWO Requirements for Training. Individual exercises may be combined and integrated to create a more challenging scenarios, e.g. connecting the crawl space exercise to the descent exercise into one scenario. During the exercises the instructor is free to introduce new elements or change the circumstances of the exercise, to challenge the participants and to provide a more dynamic scenario. For example, removing equipment, or marking anchor points as a defect. 5.6 Validity Period The Advanced Rescue Training is valid for the period stated in the table below. Certificates and training records shall be renewed before the end of a given validity period. A certificate or training record can be renewed up to two months prior to expiry and maintain the original certification date by uploading the previous certificates valid until date in WINDA.

If a certificate or training record is renewed outside of two months of expiry, it must carry the new date of certification.

An e-participant is only allowed to attend a refresher course in the specific training module prior to the date of expiry on the current certificate or training records. If a certificate is or training record is expired, the participant must attend the applicable Advanced Rescue Training to obtain a new training record.

The validity period is automatically calculated by WINDA by entering the course completion date.

5. included in an on-going training program, which includes visits to onshore and/ or offshore WTGs (tower, nacelle, hub) prior to instructing GWO ART modules, to enable them to maintain and update skills related to the GWO modules they instruct. The instructor shall physically visit the tower, nacelle, and hub of WTGs. 6. 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 7. able to analyse and justify the ART rescue equipment used, uses and limitations of this equipment included. 6.2 Practical Training Facilities All facilities shall be maintained and where appropriate, inspected and tested in accordance with current national legislation and manufacturers’ recommendations. Risk assessments shall be conducted and documented for all training facilities. The training provider shall hold the required permits to operate the facilities. The learning process is facilitated by identical or comparable elements comparing the training environment and the participants’ working environment. Identical or comparable elements enhances the 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 objective is that the practical training facility should enable each participant to individually and/or as part of a team, see, hear, and practise the taught subject matter in such a way that it resembles the working practises in a real wind turbine environment.

The following training facility items will be required for the ART training:

1. Mock-up with enclosed space to simulate the hub, with a height differentiated crawl way

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

b. the training provider can deviate from the recommended hub measurements to facilitate a specific turbine design

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

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

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

4. Mock-up to simulate under the gearbox with a max. 0.6m diameter access crawl way into the crawl space, a height between 0.6m and 0.3m and minimum 2.0m length (Nacelle, Tower and Basement Rescue Module)

Mock-up to simulate the nacelle

GWO Advanced Rescue Training Standard / V4 2023-05-02

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

b. the training provider can deviate from the recommended nacelle measures to facilitate a specific turbine design c. the nacelle mock-up must be filled with sufficient simulated assets, to create a realistic nacelle environment d. the maximum available contiguous floor space must be less than 3.0m 2 , excluding walkways of less than 0.6m width e. the sides of the nacelle should be designed in such a way as to prevent direct visual contact from within the nacelle to the teams outside of the nacelle

structural and certified anchor points (both modules)

It is recommended to connect the various mock-ups to recreate a realistic sequence. For example, connecting the nacelle mock-up with the hub mock-up. Rather than connecting a blade mock-up with the nacelle mock-up. This would provide a more realistic scenario. However, if there are practical reasons to separate the individual mock-ups, then this is allowed. For example, to allow different teams to train at the same time.

6.3 Wind Turbine Environment Explained What is a wind turbine training environment?

To apply what participants have learned (e.g. during a course) is a learning process of its own. This process is facilitated by identical elements comparing the training environment and the participants’ working environment. Thus, identical elements enhance the application of what participants have learned. The more identical elements; the merrier. 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’ (i.e. executing training end to end the way participants should perform in practice) enhances real work behaviour. So how to ‘train as you work’ and design a training environment with a high degree of identical elements? Depending on the participant’s job and tasks in the wind industry, many technicians work in the wind turbine tower and nacelle during pre-assembly, erection, commissioning and troubleshooting, or service of the wind turbine. For access up/down the tower, the tower is in general fitted with ladder sections provided with a vertical fall protection system, and tower section platforms with ladder hatches fitted with certified anchor points for attachment of personal fall protection equipment. The wind turbine may include a basement section fitted as mentioned, and primarily holding electrical cabinets.

18 / 181

Safety training

GWO Advanced Rescue Training Standard / V4 2023-05-02

In the geared type WTG, access in the nacelle is in general limited to narrow pathways along the left or right side of the main shaft and generator etc. These pathways are often ‘fitted’ with mechanical components and the like, as well as steps and small ladder sections due to variations in floor level, as part of the WTG design increasing the risk of trips and falls. Access between nacelle and hub is possible through low and often very narrow passageways. Train as you work training should be executed by doing real work tasks end to end under the actual working procedures, and/or realistic emergency situation (fire, first aid, evacuation or injured person rescue) end to end scenarios, in a wind turbine environment. 6.4 Training Equipment The equipment required for training as listed in Annex 1 must be available and must fulfil national legal requirements as listed in table A1-1 in Annex 1 where applicable. A generic approach to teaching safety equipment is applied to this module aiming to avoid potential product specific additional training on completion of this module, which may be required by the participant’s organisation e.g. prior to site or work. The generic approach is achieved by teaching a variety of safety equipment products within each safety equipment category (e.g. guided type fall arresters). This enables the participants to conduct pre-use inspection and to use other safety equipment products compared to those taught during this module (based on the manufacturer’s user manual). However, a location specific risk assessment might identify the need for additional instructions.

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

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 has been used, using the maximum allowed lanyard of length 2.00m and a fall of 1.00m, 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 ( 𝐹𝐹𝐹𝐹 )= 𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝑒𝑒 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 𝐿𝐿𝐿𝐿𝐿𝐿𝐿𝐿𝐿𝐿ℎ 𝑜𝑜𝑜𝑜 𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 ( 𝐹𝐹𝐹𝐹 )= 1.00 𝑚𝑚 2.00 𝑚𝑚 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 ( 𝐹𝐹𝐹𝐹 )=0.5 During the evacuation exercises in this module the anchor points used for the attachment of fall arrest lanyards with energy absorbers must be high enough above the ground, or structure below them, so that in the event that a person experiences a fall the shock absorber in their fall arrest lanyard can fully deploy and prevent them from contacting the ground (or structure directly below the anchor point). During the evacuation exercise the participants must be able to experience a minimum amount of descent using an evacuation or rescue device to ensure that they gain the experience of the speed of descent using these devices. This can be achieved by having the participants descend from a minimum height using a rescue or evacuation device.

19 / 181

Safety training

GWO Advanced Rescue Training Standard / V4 2023-05-02

To ensure that for all fall protection equipment that may be used that there will be enough clearance below the anchor point, and to ensure that the participants can experience a descent of sufficient duration for meaningful learning transfer, the GWO recommends that the anchor point is a minimum of 6.75m above the ground or structure directly below the anchor point. The recommended 6.75m clearance under the anchor point is explained in detail in Annex 1. If a training provider deviates from the recommended anchor point height of 6.75m to a lower height, then the following additional control measures must be in place, a. the training provider shall document a risk assessment for the lower height, this shall include calculations for the equipment to be used during the evacuation exercises, the calculations shall:

a.i use the value for shock absorber elongation that is provided by the equipment manufacturer, and,

a.ii demonstrate that the equipment will prevent the person from coming into contact with the ground or structure directly below the anchor point, and, a.iii use a formula provided by the equipment manufacturer or national legislation that is for the purpose of calculating anchor point clearance height or, where no such formula exists, use the formula in Annex 1 and,

the potential fall factor shall not exceed 0.5 and,

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

7. USING THIS STANDARD TO DEVELOP TRAINING 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 in order to reach the described learning objectives. When teaching safety equipment, a generic approach to shall be applied aiming to avoid additional potential product specific formal training after completion of this training. However, national or regional legislation, company gap analysis and location specific risk assessments may require additional product specific familiarisation 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. MODULE 1 – HUB, SPINER AND INSIDE BLADE RESCUE 8.1 Aims and objectives for the Hub, Spiner and Inside Hub Rescue Module (HSIBR Module) The aim of this module is to enable participants, through theoretical and practical training, 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.

After having successfully complete this HSIBR Module, the participants will have the ability to

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) Explain the concepts of lifting angle, angle factor and deviation considering common risks of hazardous energies and common hazards (Ability, intermediate level). 8.2 Competencies of the Hub, Spiner and Inside Blade Rescue Module (HSIBR Module) 1. Perform descending rescue operations 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 equipment.

Perform these rescue operations in teams acting as the rescue team coordinator.

Note

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

8.3 Participant Prerequisites for the Hub, Spiner and Inside Blade Rescue Module (HSIBR Module) All personnel participating in HSIBR Module training shall be medically fit and capable of fully participating. Valid GWO BST Working at Heights, GWO BST First aid, and GWO BST Manual Handling module WINDA records are prerequisites for participation. 8.4 Duration of the Hub, Spiner and Inside Blade Rescue Module (HSIBR Module) The total contact time for completing the HSIBR module is estimated to be 6 hours and 45 minutes. This is based on the times given in the module timetables and summarised in table 8-7.

The training provider must not exceed the time per day given in the table 8-4.1 below.

8.6 Equipment for the HSIBR Module The equipment required for training as listed in Annex 1 must be available and must fulfil national legal requirements as listed in Table A1-1 in Annex 1 where applicable. A generic approach to teaching rescue equipment is applied to this module. This is aimed at avoiding potential additional product specific training on completion of this module, which may be required by the participants organisation (e.g. prior to site or work). The generic approach is achieved by teaching a variety of rescue equipment products within each rescue equipment category (e.g. rescue stretchers). This enables participants to conduct pre-use inspection and to use, similar rescue equipment products (other than those taught during this module) based on the manufacturer’s user manual without additional, formal training. 8.7 HSIBR Module Timetable The order in which elements of this ART Module training are delivered may vary according to the didactical choices of the delivering training provider.
