🔍 Key Concepts

• Typical operation of an all-purpose (combination) fire hose nozzle on board ships • Relationship between handle position and valve opening/closing sequence • Differences between shut, solid stream, spray/fog patterns

💭 Think About

• Think about what position the handle must be in for the nozzle to be completely closed before any water can flow • Consider how the handle usually moves as you change from off to straight stream to wider spray patterns • Visualize operating a standard fire hose nozzle: where is the handle when you first crack it open from the fully closed position?

✅ Before You Answer

• Identify which handle position (forward, mid, back) normally corresponds to no water flow • Confirm which position you would expect to use first before entering a fire space for protection (fog/spray vs solid stream) • Make sure you are not mixing up the pattern control (twist/rotate) with the shutoff handle position
