IFSTA 13 water shuttle ops Flashcards
What three factors determine whether or not to use relay pumping or a water shuttle operation
3rd 444
Distance to water supply
required fire flow
equipment available
water tenders with Single rear axle apparatus have a maximum water tank capacity of what
3rd 446
2000 gal
In order to be considered a tender under NIMS typing what must a tender be equipped with
3rd 446
water pump
how many external fill connections of LDH are required to be considered sufficient for water tenders
3rd 447
1
true or false
Filling through the tops of tanks is dangerous and should be discouraged
3rd 447
true
What are the two primary types of large tank discharges use on water tenders
3rd 448
gravity
jet-assisted
What forms of power may be used to operate remote valve operating systems may be used on water tenders
3rd 448
hydraulic
electric
pneumatic
define jet assisted pumps
3rd 448
Utilize a small diameter in-line discharges inserted into the piping of a large tank when being supplied by fire pump water tender creating a Venturi affect - increasing water flow through the tank discharge
issues associated
must be quick to the fire pump
high velocity discharge my damage
portable tanks
what decisions must be made to determine success of a water shuttle operation
3rd 449
Location of dumpsite
location of fill site
route of travel
number of vehicles necessary to maintain supply
how much water should a supply source be capable of supplying to meet NFPA recommendations
3rd 452
1000 gpm
what type of incident command system is recommended for departments to adhere to during water shuttle operations
3rd 454
National incident management system (NIMS)
if possible fill water tenders at a rate of what
3rd 456
1000 gpm
 what may be placed to mark the stopping point for water tenders and engines at fill site
3rd 456
traffic cone
define direct pumping operations
3rd 459
Water tenders pump water from there tanks directly into the tank of an attack pumper
define nurse tender operations
3rd 460
Water tender placed adjacent to attack pumper serves roll as a portable tank a.k.a. nurse tanker
Which method is considered to be the simplest and quickest to ensure constant water supply for fire attack operation
Portable water tank operation
Single portable tank operations are adequate for fire fighting that requires relatively low flow rates of less than how many GPM
3rd 462
300
Low level strainers can allow for continuous draft to a shallow depth of how many inches
3rd 462
2”
define jet siphon
3rd 463
Attached to a section of hard intake hose & a 1 3/4” hose line.
inlet of 1.5 inches receives water from 1 3/4” drawing water into hard intake hose and transferring it to adjacent tank
if flow requirements are greater than 500 gpm, parallel jet siphons should be considered
Tender performance is based on what factors
3rd 464
Loading time
unloading time
drive train capability
tank size
 Explain field test method to determine for calculations of a tender
3rd 465
Tender is parked in a position to dump into a portable tank timer starts when valves opens tender dumps tank drives to fill site returns back to the dump site timer stops when tender is back
divide water dumped by time taken
.9 x tank size
——————-
trip time
define insurance services office formula to evaluate water tender performance
3rd 465
calculate travel time
minutes .15= 15 + distance in miles
calculate handling time


what percentage of a tenders total tank capacity is accounted for using the ISO equation and the field test method
3rd 467
90%
