Competence and fitness
24.—(1) Every controller of safety critical work shall, so far as is reasonably practicable, ensure that a person under his management, supervision or control, with the exception of where that person is receiving practical training in a safety critical task, only carries out safety critical work where—
(a)that person has been assessed as being competent and fit to carry out that work following an assessment by an assessor;
