Question 1

Question 161.
During a bushfire, a helicopter is carrying out hot refuelling operations to prepare for ongoing water bombing operations.
According to SOGs, a designated Fire Protection Crew should follow what procedures?

Answer 1

Wear full PPE:
* Full structural firefighting ensemble, including helmet and gloves
* Flash hood
* SCBA
* Ear plugs - which provide sufficient protection at 50 metres,
Do not become involved in refuelling or fire protection with extinguishers at the refuelling point.
Locate the appliance uphill, upwind, and at least 50 metres from the landing site, fuel pumps and fuel storage areas, and any incident on the airbase.
Stand by with lines of hose charged, foam eductor attached and Class B foam ready to be inducted.
Prevent water or foam streams from hitting the moving rotors. If there is no risk to life, before applying foam or water streams, seek advice on how to minimise aircraft damage. If there is risk to life, commence fire attack immediately.

Question 2

Question 162.
A 6-level building has a fire burning on the 3rd level. Heat smoke and fire gases are gradually rising through vertical openings and spreading to floors above the fire. As per the Firefighters Training Manual, what factors will mostly affect the levels reached by these stratified layers?

Answer 2

The more heat produced by the fire, the higher
these layers will penetrate.
(* the type of fuel in the fire;

* height of the building; and
* the weather.)

Question 3

Question 163.
At a 4th alarm industrial unit fire, the Incident Commander (IC) had assigned Sector Commanders, a Safety Officer and a Staging Officer with four pumps initially in Staging. The IC later requested an extra six firefighters and a Station Commander from Staging, but there was only one pump in Staging. Why was this error not identified?

Answer 3

To manage resources, the IC may nominate a minimum number of spare resources in staging. The staging officer should advise the IC when spare resources in staging are low or fall below the number nominated.

My answer:?
Crews free lancing ,
Crews poached by sector commanders ,
Staging officer not notifying I C of running low on pumps.

Question 4

Question 164.
You are responding to a fire call in a Scania 320 pumper through small roundabouts in wet weather and the driver reports that the vehicle’s brakes are operating independently and intermittently. In accordance with the Operations Bulletin 2014-02, what actions should be taken?

Answer 4

The ESP system on the Scania 320 cannot be disabled. The Scania 320 should not be driven on surfaces likely to have significant wheel slippage. If the driver is continually activating the ESP system, they are driving too fast for the road conditions and should alter their driving behaviour.

Question 5

Question 165.
According to the definitions in the STP, provide a detailed description of Hazard and Risk.

the risk assessment worksheet.

Alternatively, conduct the
operational risk assessment for the
IC and communicate the
assessment to the IC.

Confirm that all health and safety
systems are in place - eg
breathing apparatus control,
rehabilitation, heal
