Question

HOW TO RESET THE GRN MAYDAY BUTTON

Answer 1

1. notify Adelaide Fire the button was pushed in error 2. hold the ORANGE button down until one long beep is heard

Answer 2

* check, check, check

Answer 3

* Move the _rotary collar_ to 'B', it must have inadvertently been set to A or C.

Answer 4

* Release PTT and retry shortly

Answer 5

* most GRN talkgroups are agency specific and can only be reached on their own radios * GRN 17-36 are _multiagency talkgroups_ which can be reached on any GRN radio (but need to be centrally patched together).

Answer 6

* = the Region number (1) plus the 3 numbers of the registration plate

Answer 7

* 2 DIESEL : 1 PETROL

Answer 8

* contact _SAAS EOC_ (aka 5FT) enroute to scene on _TG 20_ to advise ETA of HLO to scene, using the callsign [Incident location]-HLO (eg 'Flaxley HLO') * on arrival, _select suitable site_, at least 50m dia (day) or 75 (night). If at night, marked by crossed headlights pointing _into_ wind. * Monitor TG 20 for incoming helo, then relay landing instructions, wind direction and speed * if at night, on Helo approach, ensure _all high beams and beacons are extinguished_: just use amber flashers and low beams\* ## Footnote *\*same same for runway aprons, and yes, this is often neglected at primaries, but the pilots would like it*

Answer 9

RH is a major determinant of fire behaviour: as a general guide: * \> 30% = fires are easily manageable * 15-30% = fires become increasingly difficult to control * \< 15% = fires are generally uncontrollable * \< 10% = CATASTROPHIC conditions

Answer 10

* \< 12 = LOW - MODERATE * 12 - 24 = HIGH * 25 - 49 = VERY HIGH * 50 - 74 = SEVERE = _TOBANS_ * 75 - 99 = EXTREME * \> 100 = CATASTROPHIC

Answer 11

During the _FIRE DANGER SEASON_, but not on a TOBAN day: 1. Initial response = _1st ALARM_ = 2 Tankers\* 2. Next level = _2nd ALARM_ = 2 more Tankers 3. Next level = _3rd ALARM_ = 2 more Tankers 4. Next level = STRIKE TEAMS via REGION On a _TOBAN day_ 1. Initial response = _1st ALARM_ = 4 Tankers + 1 BWC 2. Next level = _2nd ALARM_ = 4 more Tankers 3. Next level = _3rd ALARM_ = 4 more Tankers 4. Next level = _STRIKE TEAMS_ via REGION *\* = at least a 24, or sometimes 2x 14/QRVs*

Answer 12

* 1300 RPM!

Answer 13

* _Standard RCR response_ = 1 Rescue + 1 Tanker * _Heavy rescue_ = 2 Rescue + 2 Tankers * + an extra Tanker if Helicopter _landing site_ reqd

Answer 14

* _UNSTABLE_ atmospheric conditions\* may allow warm moist air at lower levels to ascend to great heights, 60,000 ft or more * the moist air _cools as it rises_, producing first rain drops (and CUMULUS CLOUDS) then hail * _Strong turbulence_\*\* within the cloud causes collisions between hail particles, creating electric fields, causing _lightning_ to jump within the cloud, between clouds, and to the ground * repeated rise and fall within the cloud can produce very large raindrops or hailstones which may fall violently to earth, accompanied by strong local winds. ## Footnote * \* = those conducive to large vertical movement of air masses* * \*\* this is why thunderstorms are dangerous to fly through*

Answer 15

the _C-Haines index_ is a is a measure of _atmospheric instability_, which is an important\* predictor of fire behaviour, because increasing instability favours generation of _convection columns_ which _increase local winds_ * _0-4_ = _stable_, fires easily controlled, models over predict fire behaviour * _4-8_ = _becoming unstable_, fires becoming difficult to control: models are good predictors * _8-10_ = _unstable_: fires are difficult to control, models under predict * _\>10_ = _very unstable_, fires uncontrollable, models dramatically under predict *\* albeit not part of traditional models*

Answer 16

* these are high white _cumulus clouds_ which develop _above the smoke column_ at a big fire: they are a _RED FLAG MARKER OF ATMOSPHERIC INSTABILITY_, and of severe and unpredictable fire behaviour

Answer 17

* CFS uses _9 litre, 300 bar fibreglass cylinders_ with a maximum capacity of 2700 litres

Answer 18

* Whistle time = out time = _50 Bar_ = 10 mins air left

Answer 19

The ECO controls the entry of BA operators into incidents 1. don _ECO vest_ & set up ENTRY CONTROL POINT at a suitable site near incident entry point 2. lay out _Green & Red & tarps_ for full & empty cylinders 3. _collect TAGS_\* from waiting operators, record cylinder pressure, confirming \>_170 bar_ 4. upon doffing, _calculate out time_ from starting pressure 5. ensure team\*\* out on time, or send rescue crew in\*\*\* * \* removing this tag from the DSU activates it* * \*\* a team = 2 operators* * \*\*\* always aim to have the next team ready to go in*

Answer 20

1. Solar Panels produce _DC current_ and feed it to an _INVERTER_ which converts it to _240V AC_ for immediate use, export to the GRID, or storage in a BATTERY system 2. Homes with solar panels have a _PV_ (Photovoltaic) _sticker on the fusebox_, and those with Batteries have an _ES_ (Energy storage) sticker 3. Traditional Batteries were LEAD-ACID arrays, but _Lithium_ types are proliferating, and can can melt down violently if pierced or overheated. 4. _EMERGENCY ACTION_ in the event of a house fire or battery emergency: * Turn off all switches in the fusebox * Treat battery leakage as HAZMAT * Cool overheated Li-Ion batteries with FOG only *(jets risk electrocution)* * Allow battery fires to _burn out_ whilst protecting exposures

Answer 21

* Electric vehicles currently lack a universal 'number plate flag' and may need to be identified individually * EVs have 2 battery systems: * A conventional _12V battery_ which runs the traditional accessories * A larger, _high voltage battery_ which powers the electric motor. * In case of _crash_: * EVs have crash sensors which should disconnect the high voltage battery, but ensure this by _disconnecting the 12V battery leads_ and pulling the _'first responder plug'_ if present (usually in engine bay) * Identify the _ORANGE high voltage cables_ and avoid cutting during rescue * Treat high voltage battery leak as caustic * In case of High voltage battery _fire_: * SCBA mandatory * use high volumes of water (\>20,000l) to extinguish and cool * _quarantine for 48h_: can reignite later*\**

Answer 22

1. ack to _Adelaide Fire_ by phone on arrival at station 2. notify _Adelaide Fire_ when _mobile_, arrived, clear, returned etc, using _K codes_ on 128 3. notify _HEYSEN DUTY OFFICER_ when mobile on _12__8_ (Heysen Duty does not see K codes) 4. upon _arrival_, send _HEYSEN DUTY_ initial sitrep on 128 as: 1. Echunga 34 arrived incident number.. 2. the _incident name_ is.... 3. the _incident commander_ is... 4. the initial SITREP is.... 5. Notify HEYSEN DUTY when _complete_ on 128

Answer 23

* Don't exceed speed limits by \>20 kmh * Stop before disobeying a RED light * Don't disobey train signals unless directed by a rail worker * You must use BOTH Lights & Sirens at all times * Don't exceed 60kmh on the freeway downtrack *\* P1 = Emergency driving, P2 = normal*

Answer 24

* Echunga Primary School has no fixed alarms or sprinklers, but it does have 4 'mains pressure' water points: * 2 _hydrants_, one at each end of the main school carpark * 2x _36m reels_, one on the external wall midway between the hydrants, and another inside the same building * These are _fed at 600kPa_ from 2x 60,000L tanks and an autostart\* diesel pump adjacent the school crossing. A _booster cabinet_ alongside the pumphouse allows the system to be pressurised by an appliance in the event of pump failure. * _Initial actions upon arrival_ 1. Locate 34 in the main carpark and commence work using 64mm layflats direct from each hydrant 2. Establish BA Entry control point ## Footnote *\*but not autostop: shut down via buttons in the booster cabinet or pumphouse.*

Answer 25

* CO2, sprayed directly on the nose through the fence at initial contact

Answer 26

1. Do not run 2. Face the dog and loudly tell it to GO HOME - most will hesitate at this .. if so, reinforce by advancing. 3. If not, '_become a tree_' ... stand immobile, no eye contact, ignore, even if nipped

Answer 27

* As a general guide, begin by halving the normal pressures, eg to 50 psi, but can go lower
