Under Regulation 13 of the Management of Health and Safety at Work Regulations 1999 and also under Regulation 4 of the same Regulations, there is a statutory requirement for all who operate equipment to hold current training certification, and then for refresher training to be carried out to ensure the continued safety and competency of all individuals. For suspended access equipment, refresher training is generally carried out on an annual basis where systems are complex or where there have been changes to the site team. Less complex systems may require less frequent training. See BS 6037-1 for further guidance.
