Which statement is NOT one of the four major components that determine the quality of master stream operation?

• A. Capabilities of your water supply
• B. Color coding of hoses
• C. Flow capabilities of supply line and friction loss
• D. Minimum requirements and desired flow rates

Answer: (B)

Master stream effectiveness comes down to how water can be delivered and used, not how hoses are labeled. The four major factors typically considered are the capabilities of your water supply (how much water and at what pressure you can obtain), the flow capabilities of the supply line and the friction loss along the route (how much flow is actually achievable given hose size, length, fittings, and elevation), the minimum requirements and desired flow rates for the operation (the target flow needed to control or extinguish the fire safely), and the capabilities of the master stream device itself (the nozzle or monitor’s achievable flow range and pressure). Color coding of hoses is not a factor that changes any of these hydraulic or operational variables, so it doesn’t determine the quality of a master stream operation.
