🔍 Key Concepts
• Fire main system components: pump, hydrants/valves, fixed piping, and flexible hoses/nozzles
• Mechanical protection and support: which parts are rigidly mounted and which can be easily damaged by heat, abrasion, cuts, or mishandling
• Operational exposure: which part is typically handled, dragged, and subjected to rough use during drills and real fires
💭 Think About
• Look at each choice and ask: which component is most likely to be physically damaged first in an actual emergency, not just in theory?
• Consider which part is flexible, frequently moved, stepped on, kinked, or exposed to sharp edges when being used.
• Think about what happens during a fire: high heat, falling debris, rushing crew — which part of the system is most at risk in that environment?
✅ Before You Answer
• Identify which component is fixed and protected (e.g., bolted down, inside machinery spaces or behind structure) versus portable and exposed.
• Consider which part, if it failed, would likely be due to wear, cuts, burns, or abrasion rather than internal mechanical failure.
• Ask yourself which item on the list is specifically designed to be handled and moved around the deck, and therefore more vulnerable.
