10.4 Equipment for 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 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 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 n eed 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
𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 𝐹𝑎𝑙𝑙𝑒𝑛 𝐿𝑒𝑛𝑔𝑡ℎ 𝑜𝑓 𝑙𝑎𝑛𝑦𝑎𝑟𝑑
𝐹𝑎𝑙𝑙 𝐹𝑎𝑐𝑡𝑜𝑟 (𝐹𝐹) =
1.00 𝑚 2.00 𝑚
𝐹𝑎𝑙𝑙 𝐹𝑎𝑐𝑡𝑜𝑟 (𝐹𝐹) =
𝐹𝑎𝑙𝑙 𝐹𝑎𝑐𝑡𝑜𝑟 (𝐹𝐹) = 0.5
During the evacuation exercises in this module the anchor points used for the attachment of fall arrest lanyard including energy absorber s must be high enough above the ground (or structure below them) that, in the event of a fall, the energy 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
