We had extensive Latchway installations on our estate and had it written in to any new builds that Latchway systems were to be installed. This avoided having different systems across the estate Latchway carried out the initial training and also trained a number of our staff to carry out training. Any contractor who needed roof access had to be trained by one of our staff before being given access. Latchway also carried out the statutory inspections which included harnesses and associated equipment. During the inspection visits they would also carry out refresher training as required. John
