fuel-controlled, initial phase of fire development the fire grows as a direct function of the fuel itself with little or no influence from the compartment environment.
If we continue to add fuel the fire will grow in size. If we remove fuel, the fire will decrease in size.
Therefore fires with more than enough air for combustion are said to be Fuel Controlled.
ventilation-controlled.
Fire development and the Heat Release Rate (HRR) is now dictated by the availability of oxygen.
This occurs during a fully developed fire when the fire is pyrolyzing more fuel than can be burnt with the available oxygen in the compartment.

Question 53.
According to STP, there are two control measures when dealing with live power at an incident.
List and describe them.
Turning Off at switchboard - Firefighters can turn off the main switch, removing fuses and switching off circuit breakers at the switchboard
involves turning off the main switch, removing fuses and switching off circuit breakers at the switchboard.
This removes power from the circuits within the structure supplied through that switchboard.
When power is turned off at the switchboard the wiring from the electricity network to the switchboard remains live until the power is isolated by the electricity company.
The consumers mains, the wiring inside the property that is still live after the switchboard is isolated, is a very real hazard for firefighters, especially because it is often hidden –in the roof, the eaves, the ceiling and/or the walls. If a conducting material comes in contact with the consumers mains it may become electrified. Fire, water or structural collapse can increase the likelihood of an electrical fault occurring.
Isolating power is the best way to control an electrical hazard but this can only be done by the electricity company, and this takes time. The electricity company needs to drive to the site, work out how the power is supplied and then disconnect the power from the network to the site.
As an interim measure, firefighters can turn off power at the switchboard.
Question 54.
According to STP - Firefighters can ‘turn off’ a solar power system to stop electricity feeding into the structure’s circuits or back to the electricity network if configured to do so.
State the recommended procedure.
STATE WORD FOR WORD
On-site consultation: Determine whether it is appropriate to turn solar system off and how best to do so.
Assume switch board is live: don electrical safety gloves and then over gloves. Have your helmet visor down and look away.
Follow the shutdown procedure. This may be on or near the switchboard or inverter.
If not found, turn off the
inverter main switch then turn off the solar panel main switch.
Consider if the benefits outweigh the risks: Restrict work as far as resonably practical to that required to protect life or prevent dangerous expansion of the incident
Isolate the power: If required, have the owner/occupier contact their electrician to isolate the power.
Question 55.
According to STP -When a battery energy storage system is present at a residence, there should be an indicator to alert you to this. What is an example of an indicator, located outside the switchboard.
ES sticker outside the switchboard
Question 56.
Operations Bulletin 2023-01- Lists operational actions to follow when dealing with Lithium-ion battery failure in small devices. List these actions.

- If the device is connected to mains electricity (eg charging) ensure that electricity is switched off prior to applying water.
- Knock-down any fire using copious amounts of water.
- Cool the battery with a cooling stream of water.
- Submerge the device in a suitable container of water if safe to do so. Use a tool such as a long-handled shovel to move the device.
- If unable to submerge the device, continue cooling and conduct thermal checks every 15 minutes until ambient temperature is maintained for 60 minutes. Note: an increasing temperature is an indication that a thermal runaway event is occurring.
- Ensure that all cells are accounted for by searching the area around the device.
- Failure to account for all cells may lead to a secondary fire event.
- Notify FireCOM that the incident involves a lithium-ion device. FireCOM will send a notification to FIRU.
Question 57.
According to STP - If solar panels, or the attached isolators, are on fire, in addition to the considerations with turning off an alternative power source what actions should firefighters take?

Do not put a ladder against the roof as the gutter may be electrified.
Extinguish the fire with a spray nozzle, using a pulse spray in a dispersed pattern
If the solar panel is at ground level consider using co2 to extinguish the fire, ensuring that there is at least 250 mm air gap between the CO2 extinguisher nozzle and any electrified components.

Question 62.
Operations Bulletin 2023-01- Lists the hazards and risks at incidents involving Lithium-ion batteries in small devices. List all as stated in the bulletin.
CHECK
Thermal runaway
Hazardous materials and leaked electrolytes.
Extreme fire behaviour
Release of toxic vapour and gases.
Projectiles
Stranded energy.
Secondary ignition
Thermal runaway is a term used to describe the rapid uncontrolled release of heat energy from a battery cell – a condition when the battery creates more heat than it can effectively dissipate. Once in thermal runaway the cell is in an uncontrollable, selfheating state and there can be extremely high temperatures, violent cell venting, flammable vapour, and fire. Surrounding cells may also be affected through thermal propagation, which can then send them into thermal runaway. Anyone in close proximity to a battery in thermal runaway may be injured. *
Extreme fire behaviour.
If thermal runaway occurs, it can lead to extreme fire behaviour where the build-up of flammable vapours in a compartment exceeds the Upper Explosive Limit (UEL). Firefighters entering the compartment may be exposed to a vapour cloud exposion when an airpath is created.
*
Release of toxic vapour and gases. The chemical compound of the battery depends on the battery design and manufacture. Vapours and gases that may vent include: − Volatile organic compounds (VOCs) such as alkyl-carbonates, methane, ethylene, and ethane. − Hydrogen gas. − Carbon dioxide. − Carbon monoxide − Soot. − Particulates containing oxides of nickel, aluminium, lithium, copper, and cobalt. − Phosphorus pentafluoride, Phosphoryl fluoride, or Hydrogen fluoride vapours. Toxic vapour can ignite and cause an explosion. Anyone in the vicinity may be injured by an explosion. Firefighters may inhale vapour or gas if not fully protected by PPE.
*
Hazardous materials and leaked electrolytes.
Electrolytes contain volatile hydrocarbon-based liquid and dissolved lithium salts. Spills are likely to evaporate rapidly, leaving a white salt residue. Evaporated electrolyte is flammable and contains alkyl-carbonate compounds. Leaked electrolyte is colourless and characterised by a sweet odour. Firefighters may be injured by ignition of the electrolyte or it may lead to expansion of the incident. Firefighters may suffer skin irritation and respiratory illness
if not protected by PPE.
- Stranded energy.
There may be stranded energy – energy that cannot be removed – in the battery, creating an electrical hazard. FRNSW is unable to discharge, recover, or identify cells or modules containing stranded energy. There is the risk to firefighters of electric shock from Direct Current (DC), Alternating Current (AC), or energised conductive material in contact with the battery. - Projectiles.
There may be projectiles as cells are ejected under pressure from the battery case during fire or explosion. Firefighters may be hit and injured by a projectile. *
Secondary ignition.
Secondary ignition may occur without warning at any time after the initial event, even up to months later. A secondary ignition is a fire occurring as a result of a second thermal runaway event (not directly related to the initial event). This second event has the same risks as the initial even
Question 63.
As described in STP - When conducting ventilation using a fan, what is the most effective inlet/outlet ratio?
1:4 (Oulet 4x larger than inlet)
Question 64.
According to SOGs - When an LPG container is involved in fire, what area of the container is considered most crucial and a high priority area for cooling?
The container’s vapour space (area above the liquid) is most crucial and is to be considered a high priority area for cooling.
Cool all containers by using sprays in preference to jets of water.
Question 65.
As recommended in STP - When conducting ventilation with a fan, the fan should be set back approximately how far from the door.
Height of the door
Question 66.
