Engaging Pump Flashcards
(106 cards)
While engaging the pump how long should you wait before engaging transmission to ensure pump gears have time to travel and fully engage.
4 seconds.
What are two additional options for cooling the pump?
Cracking a discharge not in use or placing transmission in neutral if no lines are operational.
This allows a pump discharge pressure to be maintained.
Pressure mode
This allows the engine to maintain a desire to speed.
Rpm mode
When the nozzle fire fighter indicates they are ready for water the pump operator should:
- Acknowledge request for water.
- Ensure all hose lines are free and clear of the bed section of the apparatus.
- Confirm which hose line is to be charged.
- Lock discharge handle by rotating 90°.
- AdVance throttle to desired setting.
- No pressure in intake gauge.
Total pressure will be set to that at the highest operating line and all other lower pressure lines will be needed to be:
Gated down
True or false: Use the line gauge associated with the specific discharge and used to determine the pressure in a hose line. The large pump pressure gauge can be used as a back up in event of a line gauge failure because the difference between the two gauges are minimal.
True
Akron turbo jet nozzle operates at?
100psi
Metro 1 nozzle operators at?
50 psi to deliver 160 gpm
Elkhart phantom fog nozzle Are manufactured as a 75psi standard nozzle, but per IMFD Operations are generally operated at 50 psi. This fog nozzle must remain set at 200 GPM to provide 160 GPM at 50 psi NP
True
During foam operations the convenience of a single foam tank allows for a sustained attack of _____ minutes at 125 GPM at 3% concentration, with a continuous water supply
8 min
During foam operations fire attacks using Tank water are limited to ____minutes at 125 GPM’s at our Default 3% concentration
6 min
Our foam operation standards states-foam attacks will be 125 GPM 2 1/2 inch inductor with reducer using a 13/4in line, Akron nozzle set at 125 GPM, and foam cone attached
True
During foam operations advise command when there is approximately one minute of foam remaining( One minute after _____foam tank level indicator light shut off)
1/4
What are some tips for a good quality foam:
Select the proper percentage
Keep foam line simple do not use two different hose sizes split by a wye.
Nozzle GPM must match the eductor GPM.
Keep the foam bucket less than 6 inches below the eductor.
Always flush hose, the eductors and nozzles for a few minutes with clean water when finished flowing foam.
 do not exceed the hose test pressure when pumping foam.(250psi)
Gravity foam system check:
The weekly check which is on Saturdays foam system check will consist of opening the air operated foam tank valve while watching it fully open and close. The arm on the valve should be moved at least 90° degrees.
During fire department connections the building fire pump should shut down automatically when the apparatus pump pressure exceed _____ psi and resume if this pressure decreases.
100 psi
In residential sprinkler systems the single intakes found on resident a sprinkler systems are designed to operate at ____to ____psi in the same steps can be followed for the FTC connections, except there were only be a single connection for the sprinkler.
60-75 psi

SOG 1.2.10 response time benchmark goals: what is the definition of turnout time?
The time interval that begins with the unit is dispatch and ends at the beginning point of travel time.
SOG 1.2.10 response time benchmark goals, what is the definition of travel time?
The timing of all that begins with a unit is in route to the emergency Incident and ends when the unit arrived at the scene.
SOG 1.2.10 response time benchmark goals, what is the definition of total response time.
For district purposes this is the time interval from unit being dispatched to when the units are on scene.
SOG 1.2.10 respond time benchmark goals, what are the turn out time organizational goals.
80 seconds for fire and special operations
60 seconds for EMS response
SOG 1.2.10 response time benchmark goals, what is a travel time organizational goals.
240 (4min) seconds for the first arriving unit for fire and EMS incidents
480 seconds or 8minutes for the arrival of an initial fall alarm assignment for fire calls.
