🔍 Key Concepts

• Crankcase explosions sequence: primary (oil mist ignition) and possible secondary explosion • Dangers of opening a hot crankcase after an explosion (fresh air + hot spots + oil mist) • Standard engine-room emergency procedure: secure, isolate, cool, then investigate

💭 Think About

• What happens inside the crankcase right after an explosion in terms of temperature, oil mist, and oxygen? • How could introducing air or water into the crankcase affect the risk of a second, more violent explosion? • In normal marine practice, do you investigate a damaged, hot enclosed space immediately, or do you secure and let it reach a safer temperature first?

✅ Before You Answer

• Verify which options involve adding air or water into the crankcase while it is still hot or possibly smoldering. • Consider standard safety advice in marine engineering texts about when it is safe to open a crankcase after an internal explosion. • Ask: which choice best reflects a cautious, step-by-step isolate–cool–then inspect approach rather than reacting quickly near the hot engine?
