Po Book Flashcards
For relay operations the apparatus with the largest pumping capacity should be —–
Closest to the water supply
The need for relay pumping is determined by two major factors—– and——
Amount of water needed and the distance between the water source and the scene
NFPA 1901
Standard for automotive fire apparatus, contains the requirements of pumper design
NFPA 1911
Standard for the inspection, maintenance, testing and retirement of in-service automotive fire apparatus
Out of service criteria
Pretrip road worthiness inspection
A visual inspection of an apparatus to ensure the major components of the chassis are present and in proper working condition
Functional check
An inspection where a certain system or component of an apparatus is operated to ensure that it is functioning properly
Operational readiness inspection
Inspecting an apparatus and equipment on the apparatus to ensure that all equipment is in place clean and ready for service
Post maintenance repair inspection
A specific inspection to an area of a chassis or apparatus to ensure that the unit is operating properly in accordance with the manufactures initial design
NFPA 1500
Standard on comprehensive occupational medical program for fire departments
What is the primary purpose for the pre trip inspection
Mechanical failures can be minimized and personal and public safety is enhanced
NFPA 1451
Standard for a fire and emergency service vehicle operations training program
Duel pumping
A strong hydrant is used to supply two pumpers by connecting the pumpers INTAKE TO INTAKE. The second receives the EXCESS water not being pumped by the first pumper which is directly connected to the water supply source.
Tandem pumping
Short relay the pumper taking water from the supply source pumps into the intake of the second pumper then boosts the pressure of the water even higher
Max 300’ apart
NFPA 1962
Standard for the inspection,care, and use of fire hose, couplings, nozzles and the service testing of fire hose contained the pressures for various types of fire hose
Primary feeders
Large pipes and mains with relatively wide spread spacing that convey quaintness of water to various points of the system for local distribution to the smaller mains
Secondary feeders
Intermediate size pipes that reenforce the grid with in the various loops of the primary feeders. Aid in concentration of the required fire flow at any point
Distributors
Grid arrangement of smaller mains serving individual fire hydrants and blocks of consumers
NFPA 1901 requires controls and instrument ness art to operate the pump are located on the pump panel

Intake Master discharge Tachometer Engineers coolant temp indicator Voltmeter Pump pressure controls( discharge valves) Pump engine engine throttle Primer control Tank to pump valve Tank to fill valve Water tank indicator
Polar solvents
Liquids having a molecule where the positive and negative charges are permanently separated. Resulting in their ability to ionize in solution and create electrical conductivity Water alcohol and sulfuric acids are examples of pilot solvents
Hydrocarbon fuel
A petroleum based organic compound the contains only hydrogen and carbon
Hydro carbons have a specific gravity of less then 1 which means the float on top of water
NFPA 11
Low expansion foam 20:1
Medium expansion foam 20:1-200:1
High expansion foam 200:1-1,000-1
Air:solution ratio
Bypass type balanced pressure proportioned
Foam concentrate proportioned that operates in tandem with a fire water pump to ensure a proper foam concentrate to water mixture
Reckless disregard
Act of proceeding to do something with a conscious awareness of danger while ignoring any potential consequence of so doing. Reckless disregard
Negligence
Breach of duty in which a person or organization fails to preform at the standard required by law. Or that would be expected by a reasonable person under similar circumstance
Gross negligence
Willful and wanton disregard
NFPA 1071
Standard for emergency vehicle technician professional qualifications
Fog nozzle patterns
Straight
Narrow fog=15-45 degrees
Wide fog =45-80 degrees
