A list of organizations represented on this committee can be obtained on request to its secretary. BS provides general recommendations for crane types not covered in an additional part of BS BS covers in-service inspection, thorough examination and, where appropriate, testing for the safe use of all types of crane. When all parts of BS have been published, CP will be withdrawn and BS will be revised to cover manually operated and light cranes only. Information on the background to the development and use of BS since the initial publication of BS in is given in Annex E.
The BS series has been accepted as representing the consensus of practical experience for safety on cranes. It is intended to be used in conjunction with other parts of BS to ensure, so far as is reasonably practicable, that lifting operations are carried out safely. This standard was drawn up with the participation of HSE representatives and will be referred to in relevant HSE publications. Use of this documentAs a code of practice, this British Standard takes the form of guidance and recommendations.
It should not be quoted as if it were a specification and particular 1721-5 should 71215- taken to ensure that claims of compliance are not misleading. Any user claiming compliance with this British Standard is expected to be able to justify any course of action that deviates from its recommendations.
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. Commentary, 7211-5 and general informative material is presented in smaller italic type, and does not constitute a normative element.
Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations. Subjects covered include selection of tower cranes, planning the installation including site specific design work, e.
It also covers the appropriate selection and training of personnel involved in the safe installation and use of tower cranes. NOTE Self-erecting tower cranes have been addressed briefly in this document. It is envisaged that a full treatment will be given in a future 71221-5. For dated references, only the edition cited applies.
For undated references, the latest edition of the referenced document including any amendments applies. BS all partsCode 711-5 practice for the safe use of cranesBS The competent person may require supplementary tests as part of 721-5 examination. The same principles should be applied when the operations are 71215 out at a temporary site, for example construction, or when the crane is a permanent fixture, for example in a factory or at a dock.
The safe system of work should include: Crane users have a duty to ensure that the crane is only used for its intended purpose. The safe system of work should be communicated to all parties concerned. It is essential for the safety of the operation to bw that all personnel can communicate clearly in the same language. Cranes are work equipment and it is essential that they are not used for the lifting of persons for entertainment purposes, including joyriding, bungee jumping and stunts.
The person appointed may have other duties and need not be an employee of the employing organization.

The appointed person should have adequate training and experience to enable these duties to be carried out competently. On large construction sites where multiple lifting operations are carried out by various subcontractors, the principal contractor should appoint the appointed person for the site. The b person should be notified training and experience, and that formally in writing of their appointment.
The appointed person should 71121-5 different duties on the be given authority to carry out the duties involved, including consulting appointed person, are given in 4. The employing organization should review and assess the performance of the appointed person periodically. Any corresponding instructions from the crane coordinator to the 71221-5 operators should be given via the respective signallers. In such circumstances the signallers should obtain the agreement of the crane coordinator before carrying out any operation.
This activity should be part of the initial planning process. This may include consultation with other responsible bodies if necessary and ensuring that, where different organizations are involved, they collaborate as necessary.
For further information see BS The appointed person should be given the necessary authority for the performance of all these duties and, in particular, authority to stopthe operation whenever they consider that danger is likely to arise if the operation were to continue. Duties, but not responsibilities, may be delegated to another person where considered appropriate.
NOTE As the crane operator vs required to be at bss controls of the crane when it is handling loads, it would not be appropriate to appoint the operator to be in control of the lifting operation.
For a basic lifting operation, the management of the employing organization may consider it appropriate to appoint the slinger to be in control of the lifting operation. The duties for a basic lift are considerably fewer and less demanding than for a lift at a hazardous location. An appointed person employed for a basic lift might not be suitably trained or experienced for a more complicated operation, and another appointment could be required for this.
The information given in 4. The requirement for an appointed person with appropriate training and experience also applies to installation operations. This can be by a reliable source of information, weighing the load, or calculation with allowance for possible inaccuracies.
NOTEIf cranes are used to lift loads from water, the load could also include forces due to water flow or suction and the effect of loss of buoyancy. Manufacturer’s sales leaflets should not be relied on for the rated capacity for a specific crane.
Lifting operations involving self-erecting tower cranes should take into account the recommendations given in Annex A. Consideration should also be given to the wind area of the load to ensure that its movement in the wind does not present a hazard. All persons involved in the lifting operation should be instructed to seek advice from the appointed person if any change is required to the lifting operation, or if any doubts about safety arise. The appointed person and crane supervisor should be aware of the limits of their knowledge and experience concerning lifting operations, and when conditions exceed these limits, further advice should be sought.
NOTEHazards can be from surrounding buildings, or overground or underground services. NOTEAdditional risks can arise from the crane driver not being able to observe the load while taking the initial strain, and movements due to deflections as the load is lifted clear of the supporting structure, making it not possible to put the load back down. This should lead to arranging for appropriate action to minimize any adverse effects, and to giving appropriate notice to all persons concerned.
Tower cranes should not be used for multiple lifts. Lifting operations are commonly carried out using cranes and they should be included in the Health and Safety Plan required by the CDM so that factors influencing crane safety can be assessed at a sufficiently early stage. When constructing the Plan, the ways in which the cranes are intended to be used, i. The Plan should include information to allow all parties involved in the specification, installation or use of cranes to be made aware of the fundamental criteria and planning issues needed to ensure that lifting operations are initiated and proceed in a logical and safe manner.
Designers should obtain and make available to the CDM planning supervisor, information relating to the site and type s of crane to be used. NOTE Contractors have a duty to operate cranes safely, and this can be made extremely difficult by thoughtless design which puts pressure on them to use cranes at their operating limits and sometimes encourages improper use.
In general, any organization requiring a load to be moved by crane, which does not have its own craneage, has two basic options: The difference between the two options is summarized in Figure 1. Before entering into a contract, employing organizations should satisfy themselves that the contractor has the necessary competence to carry out the work. NOTE Responsibilities for insurance in terms of the crane, personnel, the load and third parties might also need to be clarified.
The parties to the contract should ensure that: The contractor should carry out lifting operations in accordance with the BS series. NOTE Although the BS series is intended to assist organizations to comply with their statutory and common law obligations, it does not relieve them from these obligations. The user organization retains the responsibility for nominating the appointed person in accordance with 4.

Notwithstanding any ba the crane owner might have offered 71121-5 the selection of a particular crane or any other relevant matter, for example clearances, ground conditions, vs responsibility for ensuring that the crane is of a suitable type, size and capacity for the task being undertaken and for planning the operation remains with the user organization.
Therefore if an individual or organization does not have expertise in lifting operations, they should not hire cranes but should opt for a contract lift. Planning should be carried out by an appointed person who has the appropriate knowledge for the lift being undertaken see 4.
In cases of repetitive or routine basic lifting operations, this planning might only be necessary in the first instance, with periodic reviews to ensure that no factors have changed. For lifting 712-5 carried out on construction projects, further information on the duties of personnel is given in 4. Planning of the lifting operation should take into account: The assessment should evaluate the risks involved and the nature and extent of any measures required to mitigate those risks.
The appointed person should also take into consideration hazards identified by the overall site risk assessments. The results of the risk assessment should be recorded in writing and used in the preparation of the method statement see 6.
Arrangements for effective communication among the team and if necessary with adjacent crane operators in case of danger should be available. Records of training and experience of persons such as the crane operator assist in the selection of suitable personnel.
Crane operators and slingers should be trained in accordance with the recommendations given in Annex C. Those responsible for the selection of personnel should ensure that the personnel involved in the operation are efficiently organized in order to ensure good team-work in the working situation.
Work associated with lifting operations should not be carried out by personnel whose efficiency is impaired by alcohol, drugs or other influences. It is essential that all personnel in the team are made aware of both this fact and their other duties see 7.
Where personnel are under training, they should be supervised by appropriate personnel. NOTE For basic lifts it may be appropriate for one person to undertake more than one of the duties identified in 7.
The crane supervisor should be competent and suitably these to another person with trained and should have sufficient experience to carry out all relevant appropriate expertise for the lifting duties. The crane supervisor should have sufficient authority to stop the operation.
The slinger is responsible for initiating and directing the safe bw of the crane [see 8. Where continuity of signalling 721-5 required and this slinger is not visible to the crane operator, another slinger or signaller may be 71215- to relay signals to the crane operator. Alternatively, other audio or visual methods may be used. Where audio or visual methods are used, the equipment or its means of use should be such that the operator is immediately aware of failure of the equipment, to enable them to stop crane movements.
If, during the lifting operation, responsibility for directing the crane and load is to be transferred to another nominated person, the slinger should clearly indicate to the crane operator that this responsibility is being transferred and to whom, and the slinger should clearly indicate to the new nominated person that this transfer is taking place.
Furthermore, the operator and the new nominated person should clearly indicate that they accept the transfer of responsibility. The signaller may be given the operations between personnel.
