What speed is considered to classify water as swift?

• A. 0.5 knots (0.57 mph)
• B. 1 knot (1.15 mph)
• C. 2 knots (2.30 mph)
• D. 3 knots (3.45 mph)

Answer: (B)

Water is classified as swift when it reaches a speed of 1 knot (approximately 1.15 mph). This speed indicates a flow that can pose risks to those in or near the water, as it can become challenging to maneuver or control oneself in its currents. Understanding the distinction of swift water is crucial for rescue technicians, as it informs them about the potential hazards they may face during a rescue operation. At speeds below 1 knot, the water flow is generally regarded as slow-moving, which presents less danger. Once the flow reaches 2 knots (around 2.30 mph) and above, the water is classified as fast or even dangerous, further increasing the risk for those in the water. Being aware of these classifications is essential for safety in rescue situations and for effective decision-making during operations.
