According to STP, there are two control measures when dealing with live power at an incident. List and describe them
- Turning off Power - Firefighters can turn off the main switch, removing fuses and switching off circuit breakers at the switchboard
- Isolating Power - Energy authority switches off power from the network
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.
- On-site consultation: determine whether it is appropriate to turn solar power system off and how best to do so
- Assume switchboard is live: Don electrical safety gloves then over-gloves. Have your helmet visor down and look away
- Follow the shutdown procedure. If not found, turn off the inverter main switch then turn off the solar panel main switch
- Consider if benefits outweigh risks: Restrict work as far as possible to that required to protect life or prevents expanding the incident
- Isolate the power: Have the owner/occupier contact their electrician to isolate the power
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
Green ES sticker
Operations Bulletin 2023-01- Lists operational actions to follow when dealing with Lithium-ion battery failure in small devices. List these actions
If connected to mains electricity 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.
Conduct thermal checks every 15 minutes until ambient temperature is maintained for 60 minutes.
Ensure that all cells are accounted for by searching the area around the device.
Notify FireCOM that the incident involves a lithium-ion device. FireCOM will send a notification to FIRU
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?
- Conduct firefighting from the ground or an aerial appliance
- Don’t get onto the roof to extinguish fire.
- Don’t place a ladder against the roof as the gutter may be electrified
- Extinguish fire with a spray nozzle, using a pulse spray in a dispersed pattern
- If panel at ground level, consider using a CO2 extinguisher, ensuring there is a 250mm air gap between the extinguisher nozzle and any electrified components
According to STP - Overhaul is a procedure we follow after we attend an incident and extinguish the fire. For your safety during overhaul what is it essential for you to do?
Wear full Firefighting PPC and SCBA
Perform atmospheric monitoring using a gas detector
According to STP - What is the minimum PPE that can be worn at a bush fire?
- Multi-purpuse helmet
- Goggles
- Multi-purpuse jacket
- GP gloves
- Firefighting gloves (direct attack)
- Duty wear trousers
- FF Boots
- P2
Enhanced if needed
- Structural ensemble
- Protective hood
- SCBA if needed
- P3 mask if required
According to STP - Property protection is the act of protecting property from the impact of a wildfire. At a major wildfire, FRNSW crews generally engage in property protection roles. We generally have 3 strategies for carrying out property protection. Name and describe them
Line Defence
Protect the perimeter of the property until resources are sufficient for an offence attack
Ember Defence
Firefighters focus is on extinguishing embers and spot fires around structures
Backstop Defence
Firefighters retreat while fire front passes and move back in to save savable structures afterwards
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
- Thermal runaway.
- Extreme fire behaviour.
- Release of toxic vapour and gases.
- Hazardous materials and leaked electrolytes.
- Stranded energy.
- Projectiles.
- Secondary ignition
As described in STP - When conducting ventilation using a fan, what is the most effective inlet/outlet ratio?
1:4
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 containers vapour space (area above the liquid)
As recommended in STP - When conducting ventilation with a fan, the fan should be set back approximately how far from the door
Approximately the height of the door
According to Work Instruction- “Bagging contaminated gear” What equipment is required for bagging contaminated gear (not PPC) at an incident to minimise the risk presented by hazardous contaminants during storage or transport?
The appropriate bag for the type of contaminant:
- Asbestos containment bags where asbestos is a suspected
contaminant
- Yellow clinical waste bags for waste produced from
providing first aid.
- Clear contaminated gear bags for other contaminants,
including smoke
Cable ties or strong tape to seal the bags
A contaminated equipment tag to attach to the bag with relevant details.
You are responded to a bushfire with four Fire Rescue NSW pumpers two RFS tankers and one inspector, according to SOGs what class is the fire?
Class 1
According to the guideline support document for electricity SOGs - Electrical transformers in high density areas of cities maybe situated in underground vaults, if a fire occurs in one of these vaults, CO2 can be injected via a wall mounted or footpath CO2 connection box. What does the number on the connection box indicate?
Determine the number of cylinders required
According to the guideline support document for electricity SOGs - What factors affect voltage gradient at wires down?
Composition of the ground - eg concrete, road surface, soil
Moisture content
Voltage of the electrical source
According to the guideline support document for electricity SOGs - Conductors allow electricity to easily pass through them. List five conductors.
- Water – including hose line
- Metals (eg copper, aluminium, steel)
- Timber and trees
- Flame and dense smoke
- Human body
According to the guideline support document for electricity SOGs - Name four measures to control the risks associated with electricity
Stay away from the hazard. Always regard it as live until you know otherwise.
Assess the risks from at least 8 metres away from the hazard.
If suspected to be electrically hazardous, establish an Exclusion Zone.
Have the electricity company isolate power
As listed on the SIMS Worksheet: Electrical safety kit - State the inventory stored in the green canvas bag of the electrical safety kit.
1 x pir insulating gloves
1 x pair leather gloves
2 x non-contact voltage detectors
According to Recommended practice - When using the gloves from the electrical safety kit, what is the correct donning sequence?
- Put on electrical gloves first.
- Put over-gloves on over the electrical gloves to protect the
electrical glove from damage. - The cuff of the electrical glove must extend beyond the cuff
of the over-glove. - The cuff of the electrical glove must be above the cuffs and
sleeves of your PPC.
According to SOGs - FRNSW has an interagency notification policy, list the reasons NSW Police are required to be notified.
Crime investigation
Possible terrorist incident

You are responded to fire in a Correctional facility, centre or complex operated by government agencies or private contractors. As stated in FRNSW SOGs on arrival what actions should be taken?
- Liaise with the Emergency Coordinator.
- While waiting to enter, start developing the IAP
- Where entry to the facility is delayed
