🔍 Key Concepts

• Behavior of very hot cargoes like asphalt and molten sulfur when they contact water • What happens when water flashes to steam under high temperature conditions • Difference between dangers during carriage vs after discharge

💭 Think About

• Think about what occurs if even a small amount of water gets into a tank, line, or pump room where the product is over 300°F. How does water behave at that temperature? • Which option describes something that can create a sudden, violent reaction rather than a slow-developing condition? • Consider which danger has been historically emphasized in training and casualty reports for very hot bulk cargoes.

✅ Before You Answer

• Verify which choice involves water contacting very hot cargo and rapidly turning to steam • Check which option is a hazard that exists throughout loading, transit, and discharge, not just afterward • Identify the choice that can cause structural damage or serious personnel injury almost instantly if it occurs
