Earthworks - in close proximity to Power Lines and Roadways Information:
The Earthworks – in close proximity to Power Lines and Roadways Safe Work Method Statement (SWMS) is a comprehensive 21 page procedure.
This SWMS covers general hazards associated with works being conducted in the presence of overhead power lines and in close proximity to roads with public vehicular traffic and railway tracks.
Equipment includes Dozers, Excavators, Graders and road vehicles. This SWMS is to be used in conjunction with SWMS specific to items of plant (Graders, Excavators etc), Confined Space Entry and others as required.
The Earthworks – in close proximity to Power Lines and Roadways procedure is ready to use and is not a blank template. Simply add your company details, ABN, and include any site specific details or risks and make it specific to the task at hand. It is then ready for printing and to be incorporated as part of your overall OHS System.
The Earthworks – in close proximity to Power Lines and Roadways Work Method Statement can be used as part of your OHS inductions, for Tool box talks or tender applications.
Planning
Overhead power lines (including high and low voltage distribution conductors, single wire earth return (SWER), service cables to premises, communications cables and electrical transformers mounted lower than cables)
Identify:
- Maximum range of equipment and how close equipment or load can come to asset (known as design envelope)
- Clearance distances for type of asset (***)
- Type of asset/cabling (if in doubt contact electrical supplier)
- Voltage level
- Height of conductor at lowest point
- Minimum distance between wires and ground
- Degree of sag and sway
*** Minimum Clearance zones:
- High voltage electrical conductors = 2,000mm
- Un-insulated low voltage conductors = 1,000mm
- Insulated low voltage (between 50V and 1,000 V) = 500mm
- Communications cabling = 300mm
