<p>A safety device is disclosed for use in assisting in support of roofs of buildings. Use of the device avoids injury if part of a roof collapses, and the device is particularly suitable for use with roofs made from light-transmissive corrugated sheets or similar materials. The device has first (10) and second support members (20) for attachment to a pair of roof purlins (1-4), and one or more metal ropes (50A-50E) extend between the support members. In use, the ropes are typically held in tension between the first and second support members. <IMAGE></p> |
