IMPORTANT

Always follow your service or department’s standard operating guidelines or procedures.
Firefighter safety is paramount – if a drill from another state or service is in violation of your own SOP/SOG’s, it can be undertaken at your own risk. Flashover, or the service where the drill came from, is not responsible for any damages or injuries that happen as a result of undertaking this drill.

Equipment required

  • Your firefighting appliance, or a way of filling hoses with pressurised water
  • Lengths of hoses. You can choose what diameter, the concept is the same for each. In this example, 2x lengths of 70mm hose were used
  • A tarp, or some form of waterproof material large enough to fill the coiled hose
  • Traffic cones, or similar, to help keep the shape of the coil

Safety Considerations for Firefighters

This drill is all about thinking outside the box and because of that, you should have the appropriate PPC in place like you were operational.

You’ll be using pressurised hoses in close proximity to an appliance, use caution when deploying and coiling pressurised hose.

It may be useful to appoint a safety officer for this drill.

How to undertake the drill

This is a great way to familiarise new members to the appliance and the equipment onboard. It can also be used as a problem-solving drill to get firefighters to construct a water source capable of being pumped from.

The objective is to have 2 lengths of coiled hose on top of each other, lined with a tarp, then filled with water. This can be achieved in a number of ways.

As a starting point, have firefighters attempt to make the coil without any form of stabilisation. This will prove difficult as the coil will not be stable and might bow or fall out of shape.

Suggest cones be used to help keep the coil in a solid formation. Again, this can be anything from the appliance – it doesn’t need to be cones. Once the coil is pressurised and stablised, a tarp can be used to line the coil and then have water pumped into it.

Lessons learned

Here’s what Tamworth RFB had to say about the exercise.

A few options were tossed around, but it was decided that 2 lengths of 65 would probably work as a wall to line with a big tarp. After an unsuccessful attempt (the hoses collapsed) we realised the hose had to be fully charged during the build. After that, we used 4 witches hats to keep to the shape. In the photo above, the crew were putting the final wrap on before lining with a tarp. The whole thing worked really well. We filled it from the river with a portable pump then drafted back into the truck. It probably held about 2000 liters all in.
