This British Standard makes recommendations for and gives guidance on health and safety practices in shaft sinking and tunnelling. Guidance on health and safety in the maintenance, renovation and repair of shafts and tunnels is also included. The standard includes health and safety recommendations that are also relevant to cut-and-cover tunnelling and immersed tube tunnels. The recommendations are not specifically intended to apply to the construction of shafts or tunnels for the purpose of winning minerals. NOTE 1 The design, manufacture and use of plant and machinery are referred to only where safety considerations are affected. Various European Standards relating to the design of tunnel boring machines (TBMs) are currently in preparation. NOTE 2 A list of current legislation relating to tunnel construction is given in Annex A.
