Water Supply for Suburban & Rural Firefighting Flashcards
The goals of rural water supply operations are
Rapid
Efficient
Expandable
Uninterrupted
The water supply group supervisor is normally established by who
3rd engine officer
The dump site unit leader is normally established by who
5th engine officer
Who calculates turnaround time and GPM per unit in shuttle
Dump site unit leader
When at a dump site personnel need to wear appropriate PPE that includes
Traffic vest & helmet
When operating at a fill site personnel need to wear appropriate PPE that includes
Traffic vest & PFD if within 10’ of open water source
The fire flow tanker calculation is
total capacity of tanker minus 20% divided by the round-trip time
A tanker task force shall consist of the following units
1 engine
3 tankers
1 BC
The second BC will establish what
Water Supply Group (WSG)
With proper preplanning relay operations with 4” hose are feasible how far
distances over 1 mile
Dry hydrants should be back flushed and tested how often
every 6 months
Typical size of dump tanks
1500 gal = 10’3”x10’3”x30”
2100 gal = 11’3”x11’3”x30”
2500 gal = 12’3”x12’3”x30”
3000 gal = 13’3”x13’3”x30”
Low-level suction strainer will use available water to approx how low
2 inches
The maximum flow for a low-level strainer is
750 GPM
Low-profile jet siphon strainers have a max flow of what
500 GPM
These allow personnel assigned to the dump site to set up fill lines for the tanks using 3 or 4” hose
Supply line holders
A jet siphon can move how much water between tanks
800 GPM
This allows a unit to access a water supply that would normally be out of reach when using a hard-section hose
Turbo draft
During relay operations the max distance between engines is what
1,000 feet
Each fill site should support a minimum of how many fill stations
2
Tankers should be filled how
at a min rate of 1000 GPM at 100PSI
