3 Electrical Hazards |
Voltage gradient Step potential Touch potential |
|
Hazards with Electricity |
Fallen wires MVA Damaged Kiosk fires involving electricity Cutting live wires Flooded or wet buildings |
|
Dealing with Fallen Wires |
Before getting out vehicle, examine Look for wire ends, overhead wires, pools of water Cordon off area Contact SAPN KEEP PEOPLE AWAY |
|
Causes of Electrical Fires |
Faulty wires Arching Overheating |
|
Control measures for asbestos |
Minimal disturbance Wet down |
|
Decon for asbestos |
Full level 2 and BA Dust removed with air pressure or high pressure water Boots to be decontaminated Helmet decon, replace neck strap Ppe must be double bagged with yellow hazardous tag SCBA double bagged and returned to BA tech |
|
How many flaked lengths in hose box |
4 |
|
Two areas where water gear is stowed |
Water drawer and water trolley |
|
What extinguishers are on trucks |
Co2, DCP, and foam |
|
Water trolley components |
Standpipe Turncock key and handle Combination key Torch Heavy duty plate cover lifter |
|
When should appliances be checked? |
Commencement of day/night shifts and after a working incident |
|
Who is responsible for M32 form |
The driver |
|
Who is responsible for maintenance and testing equipment? |
On shift firefighters. Sap26 and sap29 |
|
Pump engagement steps |
Come to complete stop Apply hand brake Transmission to neutral Engage HP pump Engage main pump Transmission to drive |
|
Types of solar panels |
Grid connect Standalone |
|
Disengage pump |
Transmission to neutral Wait 5 second Disengage main pump Disengage HP pump |
|
What does the transfer case do |
The transfer case directs power between the engine and the pump |
|
Centrifugal pump |
In a centrifugal pump energy is imparted by centrifugal force. Force is created by rotation of an object. The force drives outward from the centre of rotation. |
|
Components of the pump |
Impeller - heart of the pump, consists of the: Eye (water drawn in) and The vanes (water thrown out) The volute - houses the impeller |
|
Priming pump |
Rotary vane pump. To pump air out of main pump |
|
Relief valve purpose |
A safety mechanism to protect branch operators on 64mm hose lines. |
|
When is the relief valve set? |
Commencement of shift or before required operation. |
|
Default position for relief valve |
Off. Only required when operating with 64mm hose lines. |
|
How to set relief valve |
Ensure throttle is at idle Turn relief valve on Wind pressure to HI Open tank to pump Open a 64mm delivery Increase to 1000kpa Wind back relief valve until green light comes on Increase relief valve slightly to knock off. |
|
Isolating solar |
Next to panel Next to inverter In fuse box |
|
When do you not use a relief valve |
HP hose lines Boosting Relaying 38mm hose lines |
|
Pump damage |
Cavitation Overheating Water hammer Also, Water directed through relief valve Operator error Water quality |
|
Advantages of water |
Cheap Available and plentiful Absorbs heat Expands 1700 to 1 to steam Easily transported |
|
Disadvantages of water |
High surface tension Reactive with certain chemicals and materials Low viscosity Will conduct electricity |
|
5 principles of friction loss |
Varies directly with length of hose For the same velocity, Decreases with increase in diameter Increases directly as the square velocity (m/s) Increases with roughness of hose Independent of pressure |
|
Reduce friction loss by: |
Eliminate sharp bends Use adapters only when necessary Keeling branches and valves fully open Use proper size gaskets Use short lines when possible Use large hoses or multiple lines |
|
Friction loss measurements |
64mm - 100kpa 38mm - 200kpa 1m - 10kpa |
|
What is ‘head’ |
Pressure created by gravity |
|
Jet reaction factors |
Changes in pressure Size of TFT Spray pattern |
|
What is PTASS |
Pin Test Aim Squeeze Sweep |
|
Distance from live electricity hazard |
10m |
|
Fire extinguisher |
Water - red Foam - blue label Dcp - white label Co2 - black label Wet chem - oatmeal label |
|
Signals for reversing |
Stop - one arm up , palm faces driver Reversing - palms of hands face chest. Both hands move back and forward. |
|
What is the 4 second rule? |
Allow a 4 second gap between vehicle in front of you at all times. |
|
Blood alcohol limit? |
0 |
|
Fives rules of breaking |
Brake in a straight line Start stopping sooner Vary brake pressure Brake prior to bends Select low gear prior to descent. |
|
4 rules of observation |
Continually check mirrors Stay alert Get the big picture Leave yourself an out |
|
Where are SOPs and SAPs located |
MOW |
|
Why use SOPs |
To provide a number of known procedures that allow firefighting crews to operate in a manner which is - systematic, efficient and predictable |
|
Why use SAPs |
Provide administrative and protocol to staff |
