Engine Company Pumping Sequence Flashcards
1
Q
How to lay supply line?
A
- Spot tailboard on hydrant
- Wait, watch, and listen for FF to say go.
- Lay line along the curb the hydrant is on.
- Crossover at the fire if necessary
- Max speed is 15 mph
- Slow to 3-5 mph on fireground
2
Q
How do you spot the apparatus?
A
- Place deck gun in a position to protect exposures.
- Spot 30 ft away from the structure or height of structure, which ever is greater.
- Leave room for ladder to get a good spot
- Consider fire attack location if no exposures.
- Provide captain with 3 views of structure if no exposure and doesn’t hinder the ladder getting a good spot or fire attack
- Don’t park the Nader power lines
- Don’t park over manhole covers on hazmat incidents

Q
What is the cab procedure for putting the truck in pump?
A
- Set parking brake
- Place transmission into neutral
- Shift transfer from road into pump
- Place transmission in drive
- listen for the pump to engage
- look for pump engaged and okay pump light
- look for speedometer to read 10-15 mph
- check to see throttle is disengaged - Quickly check gauges on dash
- oil pressure
- water temp
- volt meter
- air pressure - Double check parking brake
- don safety vest
- Watch for traffic before you open door
- Close door after exiting
4
Q
How do you pump on tank water?
A
- Insure hose clamp is on
- Consider placing wheel chocks
- Check gauges on panel ( oil pressure, water temp)
- check okay to pump light is on
- Open tank to pump valve
- Calculate engine pressure for first handline
- Check to make sure hose is cleared from bed
- Slowly open the discharge gate
- Increase the throttle to calculated pressure
5
Q
How do you change over to hydrant water?
A
- Make pullbacks
- Break supply line
- Connect supply line to intake
- Open air bleeder
- Open hose clamp
- Close air bleeder valve after all air is gone from line
- Open the intake valve while throttling down to maintain engine pressure
- Partially open tank fill valve to refill tank.
6
Q
How do you set the relief valve?
A
- Turn relief valve on
- Turn valve handle slowly counter-clockwise
- Watch for light and listen for the valve to open
- Stop turning the valve handle as soon as the valve opens
- Turn the valve handle clockwise one turn and stop
- Valve should now be closed. If not turn 1/4 turn more in the clockwise direction or until light goes out and valve closes.
- Valve is set, and doesn’t require adjustment unless engine pressure is changed.
7
Q
How to pump a line that as a pressure less then the engine pressure?
A
- Slowly open new discharge gate partially
- Allow the line to fill with water
- Wait for water to begin flowing from the nozzle
- Use the throttle to maintain correct engine pressure
- Gated down the new line to its calculated discharge pressure
8
Q
How do you pump a line with greater pressure then the engine pressure?
A
- Slowly open the new discharge gate fully
- Allow line to fill with water
- Wait for water to begin to flow from both lines
- Increase the relief valve setting by turning clockwise
- Use throttle to obtain the new engine pressure
- While throttling up gate old lines down to their calculated pressure. 7. Reset the pressure relief valve to new engine pressure
9
Q
What is the procedure to take the truck out of pump?
A
- Reduce the throttle to ideal
- Close discharge gates
- Bleed pressure from discharge through bleeder valves or nozzle
- Open the tank fill to top of water
- Check gauges on pump panel
- Close intake valve once tank is full
- Shut hydrant down
- Bleed pressure from supply line
- Take truck out of pump
- place transmission in neutral
- wait 3-5 sec for gear to stop spinning while checking dash gauges
- shift transfer from pump to road - Secure all hose and equipment used. Walk around truck checking under the truck, compartment doors, running boards, top of truck, for bottles, loose equipment, open doors, hose.
