🔍 Key Concepts

• Proper fire hose coupling technique on vessels • Difference between tools designed specifically for hose couplings vs. general-purpose wrenches • What is meant by minimum mechanical advantage when threads and gasket are already in good condition

💭 Think About

• If the threads and gasket are in good condition, how much force is actually needed to make a watertight seal? • Which option represents the simplest, least specialized method that would still reliably tighten a good coupling without damaging it? • Which tools listed are more likely to be used only when couplings are damaged, stuck, or corroded?

✅ Before You Answer

• Confirm which device is normally used first before resorting to any special tools for tightening hose couplings • Think about which choices are general-purpose wrenches versus items commonly found in a standard shipboard fire station • Ask: with good threads and gasket, would you need extra leverage, or just firm, even tightening?
