Wind Limited Access/ V2 2023-05-02
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.

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.
