Hose nozzles shall be of type that does not produce which type of stream?

• A. Fog pattern
• B. Straight stream
• C. Cone spray
• D. Wide-angle stream

Answer: (B)

Water streams from hose nozzles are designed to maximize cooling, control, and safety by spreading water into patterns that absorb heat and blanket the fire area. A straight stream is a narrow, solid jet that travels farther but concentrates water in a small area, offering less surface exposure for cooling and greater potential for steam burns and radiant heat reflection in many interior scenarios. That’s why hose nozzles are designed to avoid producing a straight stream. The other patterns—fog, cone spray, and wide-angle streams—provide broader coverage, better cooling, and more manageable attack in typical fireground conditions.
