On bull-head rail a cab-lock round the pipe may be secured to the rail web with a taper pin. These fixings prevent the pipe rotating or moving along its length and cutting into the cable. The clip will still permit some sideways movement if the pipe is struck. c) Leave sufficient slack in the cable so that if the pipe does become detached from the rail, the connection will not be pulled away. However, excessive amounts of slack cable should be avoided in order to minimise the likelihood of vandalism. Orange pipe must not be cut along its length unless special dispensation has been given. Orange pipe must not be used in tunnels or other areas of restricted Ventilation. If the pipe does ignite, it is difficult to extinguish and gives off heavy fumes. Orange pipe is generally suitable as protection for crossing walkways if it is let into the surface. When tail cables need to be protected for other reasons, such as chemical spillage in sidings or for staff safety, a concrete route or under track buried crossing should be used.
