To increase the safety of the building, multiple KATT ladders were installed between each gable, with a walkway built across the guttering for easier and simpler access to the roof space. Modular Safety Systems’ technical team carried out dynamic and static load performance testing to ensure the ladders were safe to accept a vertical safety line, meaning that workers could attach a harness to the ladders and be assured that the ladders would support their weight should they slip or mis-step. This extra protection was vital given the risk of falling onto a train track.
