Describe the basic sequence for pump operations to deliver water to a fire line.

• A. Establish an adequate water source, connect to supply, run lines with friction loss, and maintain sufficient discharge pressure.
• B. Turn on pump and place directly on the street.
• C. Only connect to a hydrant without running lines.
• D. Water supply is unnecessary.

Answer: (A)

Delivering water to a fire line requires a coordinated sequence: first secure an adequate water source, then connect to the supply, followed by running and charging the supply and attack lines while accounting for friction losses, and finally maintain a discharge pressure capable of pushing water through the hose to the nozzle. This combination ensures a continuous, pressurized path from source to the fire, even as water encounters hose friction, fittings, and elevation changes. Skipping steps—such as not establishing a water source, not laying or charging lines, or not maintaining sufficient discharge pressure—prevents water from reaching the fire with enough flow and force to be effective.
