Control measure

Monitor the impact of firefighting activities on ground conditions

Control measure knowledge

In protracted incidents, large amounts of firefighting media and plant movements can result in ground conditions becoming very soft. This may cause a hazard for any vehicles parked in, or needing to drive through, the area.

Strategic actions

Fire and rescue services should:
  • Consider using all-terrain vehicles as part of the pre-determined attendance
  • Consider pre-planning to identify ground conditions and suitable access routes and egress routes
  • Consider using on-site vehicles or plant to assist with operations

Tactical actions

Incident commanders should:
  • Be aware of the impact of firefighting run-off water or foam on ground conditions

  • Control firefighting run-off water to prevent ground conditions becoming unusable

  • Divert water to holding areas or sacrificial areas that will not impede firefighting operations or movement around the site, where necessary
  • Maintain vigilance when vehicle pumps are being used, to ensure that vehicles do not become bogged down in soft ground
  • Be prepared to move vehicles if the ground is becoming unsafe, to avoid vehicle entrapment
  • Monitor ground conditions where on-site plant is assisting with firefighting operations
  • Consider using all-terrain vehicles, especially if ground conditions are expected to become unusable for non-four-wheel-drive vehicles
