Competency of persons performing work
It is acknowledged that the competent person will rarely have all the necessary skills to sign off on work necessary for its major inspection. The successful completion of a major inspection relies on the ability of competent persons to inspect and work on the MEWP. It is critical for the unit to be re-assembled in compliance with the manufacturer's instructions and tolerances. This will include tightening bolts to within torque specifications, correctly fitting retainers and locking devices, and ensuring components are fitted in their correct orientation and position. Persons carrying out the work need to be skilled and technically competent. Equally important is the need fo r the work and procedures to be systematic and orderly this will be improved through efficient supervision both of the workers and the process. It is reasonable to expect that the competent person in charge of the work will hold the majority of the following qualifications and experience:
- Proven experience of MEWP inspection and maintenance demonstrated through the completion of a variety of work on units;
- Qualified in a mechanical trade background (automotive mechanic, diesel fitter, fitter and turner, etc);
- Knowledge and understanding of the MEWP type and its method of operation;
- Knowledge of MEWP maintenance and repair procedures documented by the manufacturer (i.e. MEWP manufacturer maintenance manuals);
- Understanding of MEWP inspection techniques;
- Knowledge of design and maintenance standards associated with MEWPs.
It is acknowledged that every person carrying out work on a MEWP may not hold a formal mechanical trade qualification. However, that person or the employer of that person needs to be able to demonstrate that they have a level of competence, such as experience in the field of work, consistent with the work they are performing and the quantity and quality of supervision they are receiving.
Where parts of the MEWP are sent to a third party organisation for repair or inspection, the competent person does not need to seek information about the competency of persons carrying out the work if the competent person is satisfied that the third party organisation is an industry-recognised specialist in the particular field. For example, a hydraulic motor is sent to a hydraulics specialist who disassembles the motor, replaces worn components and then checks the reassembled motor for correct operation. Written documentation that clearly states the work done and that the tests undertaken are provided by the third-party organisation for record purposes. The competent person must ensure that the work was carried out to a reasonable standard and the third party organisation has adhered to any instructions given by the competent person.
