Table 10.3.1 – GWO BSTR Working at Heights Module instructor to participant ratio
10.4 Equipment for the BSTR Working at Heights Module The equipment required for training as listed in Annex 1 must be available and must fulfil national legal requirements as listed in table Annex 1-1 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).
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, based on a maximum allowed lanyard length of 2.00m and a fall of 1.00m. 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹𝐹 ( 𝐹𝐹𝐹𝐹 )= 𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷𝐷 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) that in the event that a person experiences a fall, the shock absorber in their fall arrest lanyard can fully deploy and prevent the participant 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 participant 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 3.
