  3. Park in designated areas, never in front of or behind equipment.

Pedestrians

  1. Use designated walkways and crossings only.
  2. Wear hi-vis PPE. Do not walk in the haul road.
  3. Never approach a machine without the operator's confirmed acknowledgement.

Road maintenance

  2. Close a section of road with barricades and notify all drivers before work.

  • Visibility is poor (dust, rain, fog)
  • A berm, edge or surface is damaged
  • Radio contact is lost
  • Anyone enters an exclusion zone

8. Emergency response

  1. Stop, switch on hazard lights and raise the alarm on the radio.
  2. If there is a collision, keep the area clear and start first aid.
  3. Do not move vehicles until the scene is released.

9. Records

  • Speed and proximity alarm data
  • Road inspection records
