Posted By Robert K Lewis Dennis The biggest problem with staircase installation is that installers seem to think that they are exempt from any need to have protection against falls during installation. Generally they come forward with some sort of harness and landyard system. They do not seem to realise that one needs approx 4 metres to fully deploy the stanard harness arrangment. I do not see many storey heights this large. My preference is always for a fall rope from the ceiling above the well opening, suitably designed!!, one per person and the use then of the camlock ascendeur/descendeur arrangment. Properly used these can provide high levels of safety and act as a restraint system rather than fall arrest. Contact me for further discussion as the balustrade is the next interesting step. Bob
