For a progressive hose lay, what is the correct first-segment rate and the following 5-minute rate?

• A. 50, 100
• B. 150, 100
• C. 100, 150
• D. None of the above

Answer: (A)

Progressive hose lay relies on staged deployment from the water source outward, starting with a careful, controlled start and then increasing the pace as the line grows and crew efficiency improves. The first segment is laid out at a slower, deliberate rate to ensure the hose is properly connected, free of kinks, and pumping smoothly before more length is added. After that initial setup, the pace increases, with about 100 feet being laid around each 5-minute interval, allowing the line to advance steadily without overstraining equipment or the crew. This pattern fits the scenario where the first segment is 50 feet and the following 5-minute rate is 100 feet, reflecting a conservative start followed by a faster, sustained rollout. The other options would either push too much hose out too quickly at the start or set an unrealistic progression for subsequent intervals, which would compromise safety and efficiency.
