According to the Transfer and Mobility Policy, list the reasons permanent Officers and Firefighters may seek transfer or be transferred to other locations.
- Career development
- Operational capability
- Compassionate issues
- Location based transfers
- Performance/Disciplinary
According to the Firefighters Training Manual, what does the term latent heat of vaporisation refer to?
The amount of heat required to vaporise a unit weight of the extinguishing medium.
According to the Firefighters Training Manual, water is drawn from various types of water mains. Name the types of mains.
Trunk mains
Distributary mains
Reticulation mains
Insulated Sandwich Panels (ISPs), especially those with Expanded Polystyrene (EPS) cores can create an extremely hazardous environment for firefighters and may force adoption of a defensive strategy from an early stage.
According to SOGs, what are the reasons for this?
- EPS melts and flows like a liquid. It is highly flammable, inducing rapid fire spread, which is undetectable with thermal imaging cameras (due to the insulating properties of the panels) and can spread to areas remote from the fire origin.
- Panel delamination, where the hot metal panel skins bow and open up, rapidly increases the rate of fire spread, which heats the ceiling void, creates secondary pool fires from melted EPS, and causes panels to collapse
- There is an increased risk of flashover and backdraught.
- Large volumes of toxic, thick, black, acrid smoke are produced.
- Sudden, loss of structural integrity may cause substantial building collapse
According to the Firefighters Training Manual, what are the main types of aircraft?
Civil
Military
Helicopters
According to SOGs, when responding into a Rural Fire District, when are you required to send a Code 6?
When they have received a call to an incident located within a Rural Fire District, or
With the Code 1 (responding) message if it is known at the time of the call that the incident is in a Rural Fire District.
According to Operations Bulletin 2023-02. List the risk management measures that should be taken when attending incidents involving hydrogen fuel cell electric vehicles (FCEV).
Atmospheric monitoring - with gas detector for LELs to detect if hydrogen is leaking
Fire - Use a TIC to identify if hydrogen fire is present.
Thermal runaway - use TIC on the battery to determine whether thermal runaway may be occurring. If so, use a hose stream to cool.
Exclusion zone - Establish an exclusion zone (minimum 15 m) around any hydrogen FCEV incident.
The operation (or non-operation) of the pressure relief valve on an LPG storage or transport container does not necessarily mean that a BLEVE is imminent. However, if the valve is operating on an LPG storage container that has no odorant and is labelled accordingly the internal pressure of the cylinder may be rising.
According to the Firefighters Training Manual, what are indicators of a possible BLEVE?
any increase in the noise level from the valve
any sign of bulging or blistering on the outside of the tank or cylinder
In accordance with SOGs, when developing objectives, strategies and tactics what should be considered?
the response time for requested support
the requirements for relief crews and refreshments
whether a change of shift might be necessary.
You are the Officer in Charge at a hazardous materials incident, and the site manager is failing to cooperate. You advise the site manager of your authority to enter and operate under the FRNSW Act, what does it state?
FRNSW Act 1989 (22)
The Commissioner is authorised to enter, by his or her agents, any land, building or vessel where any fire or hazardous material incident has occurred and to retain possession of the land, building or vessel for a reasonable time or until an inquest or inquiry has been held relating to the fire or incident
According to the Toolkit - Conduct - Respectful Workplaces, Clear communication is one of the best ways to build a respectful workplace and to avoid conflict. What is the tool that will help employees to communicate clearly when addressing difficult topics.
Straight talk
According to the Toolkit - Mental fitness- What program offers an external service that provides professional and confidential counselling/coaching to help you with challenges, issues or concerns that may be affecting you at work or home.
Employee Assistance Program (EAP)
According to SOGs - During the de-escalation of an incident, at what stage is command terminated?
Command is only terminated when the last resource leaves the incident
What are principles of situation evaluation in incident management?
IC must identify a set of critical factors
IC can only deal with 3-7 critical factors at any one time.
Collecting and evaluating information may start before arriving on scene.
Once on scene, further information is collected and rapidly evaluated via an initial size up
Critical factors must be communicated to FireCOM.
IC should continually collect information during the incident
Critical factors may change rapidly as the incident evolves.
The IAP must be modified as critical factors change.
Once the incident is contained, the IC should take a more deliberate approach.
Situation evaluation only ends when command is terminated.
Anyone at the incident may collect information regarding critical factors. These need to be communicated to the IC.
According to Recommended Practice, state why the thermal imaging camera may or may not be suitable for use in a flammable atmosphere.
They are not intrinsically safe
