2. TERMS AND DEFINITIONS

Term

Definition

A rescue device configured with the device attached to the injured person and the loaded end of the rope is rigged inside 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”.

Active setup

Additional fall protection

4 / 76

Safety training

Wind Limited Access V3 10032026

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. 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. This extra layer of accountability helps prevent accidents, improves situational awareness, and reinforces a culture of safety on the worksite Components such as carabiners, snap hooks, or quick links used to connect parts of a personal fall protection system, in accordance with the manufacturer’s instructions and relevant standards

Buddy check

Connectors

Experienced BST qualified personDescribes a person who has gained extensive safety knowledge and skills over time. The duty holder is responsible for determining the level of experience of supervisors during limited access visits

Fall arrest

Preventing the user of a personal fall protection system from colliding with the ground, structure, or any other obstacle during a free fall. This includes fall arrest lanyards, vertical fall arrest systems and self-retracting-lifelines

Preventing the user of a personal fall protection system from going into a free fall

Fall prevention

In contrast to product-specific training, a generic approach to teaching safety equipment focuses on the similarities and differences in design, function, and operation between various equipment products This is achieved by teaching a variety of rescue equipment products within each category (e.g. rescue stretchers). As a result, participants are able to inspect and use other comparable equipment, beyond what was used in the training, without requiring additional formal training, provided they follow the manufacturer’s manual After course completion, participants are expected to familiarise themselves with the specific rescue equipment used in their own organisation (e.g. before starting work on site), using the manufacturer’s instructions from the user manual

WLA V3 Change Log

Version 3 Updates

This version includes updates from the Working at Height review held in 2025 and aligns with the Working at Height module of the Basic Safety Training Standard Version 20.

Summary of Changes:

• Alignment of definitions and training language with the GWO BST Standard, GWO ART Standard and industry guidelines • Onshore Limited Access module updated ladder and anchor-point requirements: Reinforced ladder rungs can only be used as anchor points when clearly marked or specified in the turbine safety manual, which improves both clarity and safety. • Revised equipment list: updates including PPE items, anchor-point types, and clearer grouping for rescue and evacuation devices • Added clearer guidance on work positioning, evacuation techniques, and instructor observation to support competence and help reduce training-related incidents

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 the Wind Limited Access Standard courses that are recommended by the members of GWO. The full standard comprises of two modules:

•

Onshore Limited Access

•

Offshore Limited Access

The members of the Global Wind Organisation (GWO) recognise trained persons as possessing the minimum knowledge required for visiting an onshore and offshore WTG safely, including transfer to offshore WTG. Applying this standard does not provide the training necessary to enter energised assets or carry out work in

7 / 76

Safety training

Wind Limited Access V3 10032026

an onshore or offshore environment, but merely to visit, inspect and observe when supervised by at least two experienced GWO BST trained persons.

This standard has been developed in response to the demand for recognisable Limited Access 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.

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 WIND LIMITED ACCESS STANDARD Upon completion of the Global Wind Organisation (GWO) Onshore Limited Access Module, participants will be able to behave in a manner whereby they are not a danger to themselves or others during supervised visits to an onshore WTG environment. Upon completion of both the GWO Onshore Limited Access and GWO Offshore Limited Access modules, participants will be able to behave in a manner where they are not a danger to themselves or others during supervised visits to both onshore and offshore WTG environments. The Wind Limited Access Standard (WLA) will also equip participants with the minimum knowledge, skills, and confidence to appropriately behave and follow instructions in the event of an emergency and to increase their safety through proper use of personal protective equipment and procedures during supervised visits to WTG environments.

The approved GWO Wind Limited Access Standard (WLA) provides participants with basic skills, which enable them to safely participate in supervised visits to WTG environments.

GWO Wind Limited Access Standard (WLA) does not provide the training necessary to independently visit or safely work in WTG environments. GWO recommends that persons working in WTG environments complete the full GWO BST training

Note

7.4 Equipment for the Onshore Limited Access Module

The equipment required for training, as listed in Annex 1, must be available and must meet the national legal requirements specified in Table A1-1 in Annex 1, where applicable.

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 carry out pre-use inspections and operate other safety equipment products beyond those demonstrated during 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. 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 ( 𝐹𝐹𝐹𝐹 )= 𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 𝐿𝐿𝐿𝐿𝐿𝐿𝐿𝐿𝐿𝐿ℎ 𝑜𝑜𝑜𝑜 𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 ( 𝐹𝐹𝐹𝐹 ) = 1.00 𝑚𝑚 2.00 𝑚𝑚 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 ( 𝐹𝐹𝐹𝐹 ) =0.5 During the 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 absorber can fully deploy and prevent the participant from contacting the ground (or structure directly below the anchor point). During the evacuation 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 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

14 / 76

Safety training

Wind Limited Access V3 10032026

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

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

a.ii demonstrate that the equipment will prevent the person from coming into contact with 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 or, 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 4.5m above the ground

7.5 Onshore Limited Access Module Timetable The order in which elements of this WLA Module training are delivered may vary according to the didactical choices of the delivering training provider. The delivery of this module must comply with the requirements described in the GWO Requirements for Training .
