M.6.3 Before carrying out ultra-high-pressure water jetting, blasting or spraying, steps should be taken to minimize the likelihood of injury or damage to rope access equipment, e.g. if the lance or blast nozzle is inadvertently pointed at any part of the user’s body (or that of another person) or at vulnerable rope access equipment. Protection could be achieved by various means, e.g. using a lower pressure and/or, for the prevention of injury, by providing suitable protection to the legs and feet such as leg guards, protective over-boots or metatarsal guards. The length of the lance could be extended to make it difficult for the user to point the blast nozzle at his/her body. Appropriate attachments with resistance to cutting, melting and abrasion should be used when any grinding /welding/ blasting /ultra-high-pressure water jetting works are undertaken.
