In rural water supply operations, the fire flow that can be obtained from a particular unit can be estimated using what formula?
Total capacity of the tanker minus 20 % divided by the round trip time.
Page 10
What formula is used to determine the needed fire flow for rapid fire control per the National Fire Academy?
[(Length x Width / 3) x # of Floors] + 25% for each exposure

- Lay out supply line from the driveway to the incident. This should be done from where the supply pumper and dump tanks are to be located (the dump site). This may require a split lay.
- Assign fifth engine to fill site operation duties and designate fill site location.
- The lay out from the first engine should include a Siamese on the supply line whenever possible.
- Advise incoming units of the mode of attack and supply line position according to the preplan
Page 20
What are the responsibilities of the first due tanker in a shuttle operation?

- Once a draft is established from the dump tank by the dump site engine (normally the second engine), the tanker dumps its remaining water into dump tanks.
- Once the tanker is empty, this unit becomes part of the shuttle operation and proceeds to the fill site.
