Exposed high voltage conductors can cause electric shocks or bums even if not touched by personnel. A reasonable level of mathematical and mechanical aptitude is therefore likely to be required.

Craneage arrangements The climbing of a tower crane is often accomplished by using the crane being climbed to unload and handle all the equipment and components involved in the climbing operation.

Multiple crane types If there is a requirement to operate more than one type of crane, ba should be given for each type and, although this would not normally require a re-run of the complete basic training course, it should cater for the differences between types of crane. This should include adequate edge protection on working platforms or the use of fall protection Personal Protective Equipment PPE such as full body harnesses and shock absorbing lanyards.


The nature and extent of this training depends on the complexity of the new equipment and the degree of difference from the equipment with which they are familiar. Records of training and experience of persons such as the crane operator assist in the selection of suitable personnel.

The frame is then lowered until the joints on the crane superstructure engage with the top of the new section. Site visits As part of the planning process it is essential that the person carrying out the planning visits the site at which the operation is to be carried out.

On large construction sites where multiple lifting operations are carried out by various subcontractors, the hs contractor should appoint the appointed person for the site. To achieve and maintain a safe system of work for the implementation of a permit system several conditions need to be met and these should include the following: It has been assumed in the preparation of this British Standard that the execution of its provisions will be entrusted to appropriately qualified and experienced people, for whose use it has been produced.
