21.5 Availability of Operators Thorough examination will require the crane to be operated from the control cab whilst the competent person is examining other parts of the crane. Arrangements must be made to ensure that an operator is available on such occasions. 21.6 Availability of Maintenance Staff If the competent person carrying out the thorough examination requires the removal of covers and guards to facilitate the through examination of concealed parts, the owner of the crane should ensure that suitable personnel are available. 21.7 Thorough Examination Area The area in which the thorough examination is being carried out should be of adequate size and cordoned off to prevent access by persons not directly involved in the examination. 21.8 Test Area Careful consideration should be given to the condition of any area where tests are to be conducted. The recommendations provided in the operating instructions for the crane relate to operations within the rated capacity and more stringent requirements apply when loads are being applied for the purpose of testing. The ground should be level, well consolidated and capable of withstanding the loads applied to it. There should be no hidden dangers such as cable ducts, drains, pipes, back-filled areas, cellars or other subterranean weaknesses. Cranes should not be tested in the vicinity of overhead power lines. The test site should be of sufficient size with unrestricted overhead clearance to allow the unobstructed movement of the crane and load throughout its test movement, for example slewing, derricking and travelling. It is preferable that tests are not conducted over high risk areas, for example a public highway, railway, occupied buildings or in the flight path of airports. If due to the requirements of usage this is unavoidable, arrangements should be made with the appropriate authorities. If load testing is being carried it must be borne in mind that the crane might not withstand the loading. All personnel not essential to the test should be kept away from the area. The test area should be cordoned off and notices posted prohibiting unauthorized entry. The site adjacent to the test area should be clear of plant and property which could inhibit the test. 21.9 Availability of Site Facilities Arrangements should be made to ensure that site management, safety and welfare facilities are available to the competent person and any personnel assisting them both within and outside normal working hours. Facilities should include office space for the review of documentation. 21.10 Lone Working Lone working should be avoided at all times by suitable liaison with the person in control of the site to ensure that site personnel are always in attendance. 62
The planning process for work at height on mobile cranes should take into account the particular hazards of lone working and thorough examination at height by lone workers should not be undertaken. 21.11 Work at Height Some thorough examination activities on erected mobile cranes may require competent persons to work at height outside edge protected areas on the mobile crane structure. The Work at Height Regulations 2005 set out a hierarchy of fall protection measures to be taken when planning work at height. This means that those planning work at height on mobile cranes should:- � Avoid work at height wherever possible and actively seek solutions to facilitate this; � If this is not possible, use “collective” means of protection such as guardrails; � If this is not possible, use “personal” means of prevention such as work restraint; � If this is not possible, use a personal fall protection system such as a work positioning system or fall arrest system; � Additionally provide training and instruction or take other measures to prevent any person falling a distance liable to cause personal injury. Where a risk assessment indicates that a personal fall protection system is required a work positioning system should always be used in preference to a fall arrest system. Where the use of fall arrest personal fall protection systems are unavoidable there will be a risk of the wearer being left suspended following a fall and arrangements must be made to ensure that they can be rescued in a safe and timely manner (See Annex 1). Where work is being carried out on mobile tower cranes suitable and sufficient arrangements must be put in place for the rescue of personnel from height. This matter is dealt with in the CPA Technical Information Note TIN 013 - Rescue of Personnel from height on Tower Cranes, which may be downloaded from the CPA web site. 21.12 Isolation of Systems During Thorough Examination To avoid the risk of trapping, crushing, shearing or electrocution during the thorough examination of mechanisms on mobile cranes, all systems should be provided with a 63
