The TRA said the collaboration was designed to answer the high level of enquiries the association receives from members asking for advice on safe working practices, particularly for operations where they have no control or where they have no knowledge of the handling aids or methods of erection available.

The datasheet, entitled “Health & Safety policy for the loading, haulage, delivery and erection of trussed rafters on site – a definition of responsibilities”, sets out the responsibility of TRA members when they enter into a supply only contract.

It covers the loading and haulage of trussed rafters, unloading on site, storage and construction of roofs, including clarifying the trussed rafter supplier’s position under the Construction (Design and Management) regulations.
