The purpose of the apparatus is to arrest the fall of the worker should they fall. Broadly the apparatus comprises at least two support posts having an upper end and a lower end supported on the structure and spaced apart from each other on the structure. Each support post has an I-shaped cross sectional configuration. The apparatus also includes a clamp on the lower end of each support post for clamping the post to the structure. The clamp itself comprises a base plate fast with the support post, a secondary plate or clamping plate spaced beneath the base plate, and fastening elements for drawing the two plates, towards each other with a member of the structure firmly clamped there between. The base plate projects laterally outwardly from the post on two opposed sides of the post, and defines at least one slot aperture on each said opposed side of the post through which the fastening elements are passed. Each post also has connecting formations towards the upper end thereof and an overhead safety line extending between said posts at a height of 1.7 to 2.0 metres above the member on which the posts are mounted. Each worker who works on the structure is fitted with a harness and a safety lead that can be releasably clipped to the safety line. This arrests the workers should they fall.Field of SearchPITCHED ROOF CONFORMING SCAFFOLDSAFETY DEVICE, PLATFORM ASSOCIATED Railing TRAVERSING, TRACK-MOUNTED Bracket moved by mechanical operator (e.g., spring, threaded shaft, pulley and rope) RAIL Nonaligned slots Adjustable Removable prop or brace combined with structure component Upright Upright Upright (e.g., post, pole, etc.) | |
