Theory and practical assessment, carried out on the employer's own machine, on their site.
No UK government body issues a licence to operate a 360 excavator, and no statute requires one.
The duty to train and assess competence sits with the employer, under the Health and Safety at Work etc. Act 1974 section 2(2)(c) and PUWER 1998 regulation 9.
PUWER 1998 is supported by the Approved Code of Practice L22, safe use of work equipment, which sets out the training regulation 9 requires; HSE guidance HSG47 applies to underground services before digging starts.
Where the excavator is used for lifting, LOLER 1998 applies, with thorough examination of the lifting accessories and a planned lift.
The employer still authorises each operator in writing under PUWER 1998 regulation 9; the certificate, unit credit, records and site evidence statement are the evidence the employer relies on for that decision, not a substitute for it.
