🔍 Key Concepts

• Behavior of a fire hose under pressure • What happens when a nozzle is not controlled • Relative likelihood and severity of each listed hazard

💭 Think About

• Which option describes the MOST immediate and serious hazard when water is flowing and no one is holding the nozzle? • Think about how a high‑pressure hose physically reacts if the nozzle is free to move. • Which choices could happen with ANY loose hose, and which depend specifically on it being CHARGED with water and the nozzle OPEN?

✅ Before You Answer

• Focus on the option that clearly involves water pressure and reaction force at the nozzle. • Ask which effect is sudden, violent, and most dangerous to nearby crew. • Eliminate any option that does not depend on the hose actually being charged and flowing.
