The Flooded Causeway and the Ambulance Request
Overnight rain has closed the main road. You are the officer in charge of a single pump and crew of four. A call comes in: a farmer 4 km down a gravel road has chest pain, and an ambulance is 30 minutes away on the other side of a flooded causeway. The causeway is normally 20 m long and 30 cm deep at the marker, but the water is now running fast and brown, and debris is passing. A local says he crossed it an hour ago in his ute. Your pump is a heavy vehicle but not a dedicated flood rescue appliance; you have no swift-water equipment. A second call reports a car stranded on a low bridge 2 km the other way.
1. How do you decide whether to cross the causeway?
Read the worked answer
Do not drive across. Reasoning:
- Depth is unknown and changing - the marker is a guide, not a measurement, and flowing water at 30 cm can float or sweep a vehicle; fast brown water with debris is worse.
- The road surface may be scoured or missing under the water; a local crossing an hour ago does not tell you what is there now.
- Your vehicle is not a flood rescue appliance and you have no swift-water equipment; if you stall or are swept, you create a second incident and put four crew at risk.
- The ambulance is 30 minutes away - the right move is to get medical help to the patient, not to move the pump into the water.
Decide on capability and conditions, not on the local's anecdote or time pressure.
2. What is your plan for the patient and the stranded car?
Read the worked answer
Patient:
- Request the ambulance and a flood rescue/boat resource through control; give the location and the causeway status.
- Ask the farmer or a neighbour to bring the patient to the near side if a safe route exists on foot at the edge, and have a crew member meet them with first aid.
- Keep phone contact with the patient, give first aid advice, and record times.
- Do not send crew into the water without swift-water PPE and training.
Stranded car:
- Establish voice contact and tell occupants to stay in the car, not to walk out into moving water.
- Request a flood rescue resource; if the car is stable and not in rising water, monitor.
- Prioritise by immediacy of risk: chest pain outranks a stable stranded car, but both need the right resource, not a heroic crossing.
3. What would change your decision?
Read the worked answer
- Water dropping and clearing, with a measured depth and slow flow, and a confirmed road surface - then a single vehicle crossing with a spotter may be considered.
- A trained swift-water crew with a boat or line arriving - they make the rescue, not you.
- The patient deteriorating - that increases urgency but does not make an unsafe crossing safe; it increases the case for the fastest safe medical resource.
- A confirmed alternate dry route - check with control and locals before assuming none exists.
What does not change it: a local's anecdote, time pressure, or the fact that the pump is heavy.
