🔍 Key Concepts

• Guarding of rotating machinery requirements for deck equipment like windlasses and winches • Difference between accessibility for observation vs. protection from moving parts • Basic principles of crew safety around moving mechanical parts

💭 Think About

• Think about what is most dangerous about windlasses, winches, and hoists: what parts can actually injure someone? • Which choice reflects a general safety principle that would apply to almost all rotating machinery on deck, not just in special cases? • Consider whether visibility, distance limits, or paint color are usually enough to prevent entanglement or contact injuries with moving gears.

✅ Before You Answer

• Identify which option specifically addresses rotating components and prevents direct contact with them • Ask yourself which choice you’ve seen reflected in real-life shipboard machinery installations or safety diagrams • Eliminate any options that sound like they would be impractical to enforce or are more about convenience than physical protection
