Useful checklist
for Hazard Reduction
WARNING - This list is NOT exhaustive nor does it necessarily apply to all situations in proximity to Power Lines. A Site Specific "Job Safety Analysis" (JSA) or "Safe Work Methods Statement" (SWMS) should always be prepared and discussed prior to commencing work.
- Monitor weather conditions. Powerlines can sag in extreme heat and sway in strong winds. They may be difficult to see at dawn and dusk.
- Earth Chains. Where mobile plant has been fitted with an Earth Chain it should be fully extended at least a metre along the ground. This decreases the resistance between the Equipment and Earth and increases the likelihood of any fault being detected at the substation (hopefully tripping safety equipment or fuses).
- Ground stability. Never operate on unstable or recently excavated soil. Use footing support if in doubt.
- Measuring Distances. Never put anything close to the Power Line such as a tape measure or even plastic conduit. The No-go-zone also applies to measuring devices. Step out or measure distances on the ground, using markers if necessary. Vertical distances must be estimated using visual methods only.
- Familiarise yourself with the equipment and the location. This applies to everyone likely to operate or work in proximity to the plant. Understand also the conditions of any permit or OHS regulations.
- Consider all other movable items at risk of movement in the No-Go or Spotter Zone. This could include plant such as trucks or cranes - and even material being moved such as structural beams or wall panels.
- Personal Protective Equipment should be checked prior to use for expiry-date, damage, wear and correct fit. If in doubt withdraw from use.
- Traffic Management. Hazards to Pedestrians or anyone likely to encroach on the Worksite must also be considered. Relocate paths, driveways and delivery/ storage areas away from hazards.
- Accredited Safety Spotter must be on the ground and in clear view of the platform and any hazards. This is COMPULSORY whenever working within 6.4 metres of any electrical lines or equipment up to 66kV. Towers & conductors carrying voltages in excess of 66kV have a 10 metre No-go-zone.
- Use a Platform Shield. Clear perspex provides maximum visibility, but plywood or masonite boards can also be securely fitted to the platform for added protection if working in the Red or Yellow Zone.
- Focus on the hazards & risks - as much as what needs to be achieved. If you can't eliminate a hazard you must take steps to minimise the risk.
