🔍 Key Concepts

• Crankcase explosion prevention procedures for diesel engines • Manufacturer and safety guidelines after abnormally high bearing temperatures • Need for sufficient time for cooling and oil vapor dissipation before opening a crankcase

💭 Think About

• What danger are you trying to avoid by waiting before opening the crankcase after a high bearing temperature? • How long would it reasonably take for hot spots and flammable oil mist to cool down and disperse inside a large diesel crankcase? • Which option best reflects a conservative safety margin typically used in engine-room procedures?

✅ Before You Answer

• Verify what standard marine engineering practice says about minimum cooling time before opening a crankcase after overheating • Consider which time is long enough for metal temperature and oil mist concentration to drop to safer levels • Eliminate any option that seems too short to significantly reduce the risk of crankcase explosion or flash fire
