Q

According to STP - Where should Warden Intercom Points be in a building?

A

· At EICIE (Chief Wardens Handset)

· Within 4 m of exit within each emergency zone

· Within 4 m of exit on each storey

· Within emergency lift shafts

· Adjacent to FDCIE if remote from EICIE

16
Q

According to Operations Bulletin 2020-04 - Failure to report damage. When an appliance is found to have unreported damage, the Fleet Operations Officer or Regional Maintenance Officer will notify the Station, Duty, and Zone Commander in writing. The responsible station must submit what form within 8 days?

A

Agency Member Motor Vehicle Claim Form

17
Q

According to the Fire ePermit policy, what aspect of the planned fire does the permit take into account.

A

The safety aspect

18
Q

According to STP, name the components in an AS 2118.1 sprinkler alarm valve room.

A

(1) Main stop valve

(2) Test drain

(3) Sprinkler test facility

(4) Sprinkler alarm valve

(5) System pressure gauge

(6) Deluge valve

(7) Water supply with water supply pressure gauge

19
Q

According to STP, there are two control measures when dealing with live power at an incident. List and describe them.

A

Turning off power - involves turning off the main switch, removing fuses and switching off circuit breakers at the switchboard.

Isolating power - the best way to control an electrical hazard but this can only be done by the electricity company, and this takes time.

20
Q

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.

A
  1. On-site consultation: determine whether it is appropriate to turn solar power system off and how best to do so
  2. Assume switchboard is live: Don electrical safety gloves then over-gloves. Have your helmet visor down and look away
  3. 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
  4. Consider if benefits outweigh risks: Restrict work as far as reasonably practical to that required to protect life or prevent dangerous expansion of the incident
  5. Isolate the power: If required, have the owner/occupier contact their electrician to isolate the power
21
Q

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

A

ES Sticker

22
Q

Operations Bulletin 2023-01- Lists operational actions to follow when dealing with Lithium-ion battery failure in small devices. List these actions.

A

Use caution when approaching the device as thermal runaway and vapour release may occur without warning. 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.
23
Q

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

A

· Wear SCBA and a full set of firefighting clothing

· Perform atmospheric monitoring using a gas detector

24
Q

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?

A
  • Conduct firefighting from the ground or an aerial appliance. Do not get onto the roof to extinguish the fire. 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.
  • NSW Fair Trading notification form to be completed at completion of incident
