2. TERMS AND DEFINITIONS Term Definition

Additional fall protection

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”. 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

Experienced BST qualified person

Describes a person who has gained extensive safety knowledge and skills over time. The duty holder is responsible for determining the experience level 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. Fall arrest system Personal fall protection system which limits the impact force on the body of the user during fall arrest. Infrequent visitor Describes a visitor with limited or no familiarity with WTG environments and safety procedures for entering them. Must For clarity where the word ‘must’ is used in this standard it shall have the same meaning as ‘shall’. Personal fall Assembly of components intended to protect the user against falls from height, including a body holding device and an attachment system, which can be connected to a reliable anchorage point. Rescue system Personal fall protection system by which a person can rescue themselves or others, in such a way that a free fall is prevented. Restraint system Personal fall protection system which prevents the user from reaching zones where the risk of a fall from height exists. Selfie A picture you take of yourself.

Shall

Verbal form used to indicate requirements strictly to be followed in order to conform to this training standard and from which no deviation is permitted.

Should Verbal form used to indicate that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others, or that a certain course of action is preferred but not necessarily required. Supervised visit Describes a visit to an offshore or onshore windfarm environment, whereby the visitor is accompanied and supervised by at least two experienced GWO BST qualified persons. Supervisor Describes a person who is responsible for conducting and ensuring procedures and that safety is correctly maintained during visits and in emergencies. This includes conducting pre-use inspections on equipment and carrying out buddy checks.

Visitor

A person without the training necessary to work within a WTG environment. This person is not expected to be able to act or take responsibility for safety or procedures during supervised visits.

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:

1) Onshore Limited Access 2) 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 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.

9 / 73

Safety training

Wind Limited Access/ V2 2023-05-02

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

5.1 Overview The GWO Wind Limited Access is divided into the following two modules:

Module 1: Onshore Limited Access Module 2: Offshore Limited Access

The Offshore Limited Access Module must be taken in conjunction with the GWO Onshore Limited Access Module as a single day training

Note

5.2 Target Group

Persons who infrequently visits to WTG environments.

5.3 Aims and Objectives Training in accordance with this Wind Limited Access Standard will enable participants to behave in a manner whereby they are not a danger to themselves or others during supervised visits to onshore assets, and with the completion of both modules, during transfers and visits to functioning onshore and offshore assets. This standard does not provide participants with the skills or knowledge to safely work in WTG environments or to participate in supervised visits to WTG assets where there are increased safety risks, for example faulty or under construction. 5.4 Duration of the WLA Standard Modules The total contact time for completing the Wind Limited Access Standard is 7 hours and 0 minutes. This is

7.4 Equipment for the Onshore Limited Access Module The equipment required for training as listed in Annex 1 must be available and must fulfil national legal requirements as listed in table A4-1 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 a site visit 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 (shown below) using the maximum allowed lanyard of length 2.00m and a fall of 1.00m. 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 ( 𝐹𝐹𝐹𝐹 )= 𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 𝐿𝐿𝐿𝐿𝐿𝐿𝐿𝐿𝐿𝐿ℎ 𝑜𝑜𝑜𝑜 𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙𝑙 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 𝐹𝐹𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎𝑎 ( 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 fixed length fall arrest lanyards must be high enough above the ground (or structure below them) that, in the event of a fall, the shock absorber in their fall arrest lanyard can fully deploy and prevent the participants 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 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. 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.

15 / 73

Safety training

Wind Limited Access/ V2 2023-05-02

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. Use the value for shock absorber elongation that is provided by the equipment manufacturer b. Demonstrate that the equipment will prevent the person from coming into contact with the ground or structure directly below the anchor point c. 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, Section 4. The potential fall factor shall not exceed 0.5 and 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 .
