b) inspections and maintenance, generally carried out at three-monthly intervals, with a more extensive inspection carried out generally at six-monthly intervals;
c) load testing carried out annually;
d) LOLER thorough examinations generally carried out at six-monthly intervals. The inspection reports should be maintained in a log on site.
