4 Roles and responsibilities
COMMENTARY ON CLAUSE 4
It is vital that all persons and organizations involved in the use of anchors understand their role and responsibvlites, in order that the recommendations made in this British Standard can be implemented at each stage of the fulfilment of a project
A person or organization can take on more than one role.
Any person who at any time changes a specification without notifying the original specifier is deemed to have taken on the role and responsibilities of the specifier (see 43).
It Is recommended that one person be identified as having overall responsibility for the structure within which an anchoiage is e.pected to function, from commencement of Its consideration through the construction stage to commissioning of the buildingiproject. This person will normally be the designer. As certain parts of this activity, such as the specific acts of selection, design and or specification of the anchor itself, may be delegated to others. e.g. specialist subcontractors, the role of specifier Is identified so as to set Out the responsibilities to be fulfilled by the person with that role The spefier may be the designer.
The installation of anchors might require the use of procedures or products that are potentially hazardous. Attention is drawn to the Health and Safety at Work. etc. Act 1974 191.
4.1 Manufacturer/supplier
Anchor manufacturers and suppliers should provide such information as is necessary for the specifier and the installer to ensure the safe selection, specification, installation, use, maintenance, cleaning, dismantling or disposal of the anchor without risk to safety or health.
NOTE See Clause 6 for details of the information to be supplied.
While anchor manufacturers and suppliers may provide advice, for which they should take responsibility, that does not make them the specifier in the context of this British Standard, as they do not have responsibility for the selection of the anchor within the project.
Suppiers of anchors should take care to supply anchors as ordered by customers.
Specifications of anchors that have been ordered should not be changed unless the change management procedure in Clause 10 has been followed and the proposed change has been approved by the specifier.
