Study These Flashcards
A

Refer to preplan and lay out supply line from predetermined location to 1st engine

25
Direct Fill Operation: 2nd engine
Less than 200 Ft: transfer water to tanker, if non available, supply attack engine through siamese 200 to 1000 ft: Lay out from dump site to 1st tanker and supply tanker 1000ft : Lay out from predetermined preplan
26
Direct Fill Operation: 2nd tanker
Less than 200': Transfer water to 1st tanker and shuttle 200' or more: Position at dump site, connect to siamese attached to 2nd engine supply line and be direct fill tanker
27
Direct Fill Operation: 3rd engine
Driver transfer water to tanker at dump site join the shuttle
28
Direct Fill Operation: 4th engine
transfer water to tanker, driver stays with rig to join shuttle
29
Shuttle Operations: 1st tanker
position close to attack engine Drop a siamese if not done by 1st engine
30
shuttle operation: 2nd engine
Establish nursing operation Establish Dump Site Operation Leave nursing set up in place for supplemental supply or to fix any dumpsite failures
31
shuttle operation: 3rd engine
Crew staffs dump site supply water into system when no tankers are available Position out of route of travel
32
shuttle operations: 4th due engine
transfer water to tanker at dump site Join Shuttle if needed
33
At what distance is a relay operation feasible what can be set up prior to as supplement
Feasible at distances over 1 mile Recommended a water shuttle supplement relay as its being set up.
34
What Sources where Dry Hydrants typically installed
Ponds, Lakes or streams sometimes swimming pools
35
When should dry hydrants be backflushed
Tested and backflushed every 6 months
36
needed to connect and draft from a dry hydrant
Need 4.5" to 6" double female National Pipe Taper bell Adapter 6" double female
37
Storage underground tanks should be checked....
Every six months for proper operation
38
Storage tanks (underground) Should NOT
Be used as sole water source due to typical sizes
39
Static water sources
Ponds, Lakes, Rivers, Bays, Streams and Pools consider risk vs benefit when using pool due to needed weight from water to support construction of pool
40
Minimum equipment carried on rural engines
Two 6" Hard sleeves 6" floating dock strainer LDH: 1000ft min or 2000ft of 3" Siphon Device Adapters 5 to 6" Adapters 4 1/2 to 6" double female 8 Adapters: (Four 2 1/2" male to 4" stortz) (Four 2 1/2" female to 4" stortz) 4" siamese, manifold or gated wye Two gated wyes set up for 4" to 2 1/2 connections
41
Preferred methods for continuous water supply at rural setting
Nursing - Direct Fill
42
Dump Tanks Sizes
1500 Gallons: 10'3" x 10'3" x 30' 2100 Gallons: 11'3" x 11'3" x 30' 2500 Gallons: 12'3" x 12'3" x 30' 3000 Gallons: 13'3" x 13'3" x 30'
43
Low-Level Suction Strainer minimum water depth and maximum flow
Allow for water level to be used up to 2 inches Max flow: 750 GPM
44
Low Profile Jet Siphon Strainer can be used to transfer water from one drafting tank to another: What does it allow engines to do How do you establish flow Minimum flow
Allows engines the ability to get water from dump tanks without drafting Charging 1 3/4 a continuous flow is established Minimum flow for siphon is 500gpm
45
How does the Jet Siphon move water How many GPMs does it move between tanks
uses venturi effect moves up to 800 gpm between tanks
46
Maximum distance between engines during a relay
1000ft
47
Water storage tank must be ______ after use
systems must be refilled after use
48
Dry Hydrant Measurements

49
How many dump tanks are carried by tankers Size of dump tanks should equal what capacity
One or Two The capacity of the tank which is carrying them
50
At what pressure should the clappered siamese dropped at the dump site be supplied at during a nursing operation
70 psi
51
At what minimum rate should the fill site engine transfer water to tankers
One at a time tankers shall be filled at 1000 gpm at 100psi

Through a designated relay engine assigned by the WSGS
54
If A fireboat is employeed as part of the water supply operation what should be assigned to its location
1 engine
55
How can weather hinder the use of static sources
Drought: water level too low Extreme Cold: Ice must be cut to access water Flooding: Debris can clog strainers
56
How does an automatic air primer operate
Uses air supply from apparatus onboard air tanks to evacuate air from suction hoses and the pump with a venturi effect
57
What will an automatic air primer placed in "automatic mode" do
Priming automatically begins when discharge pressure drops below 20 PSI
