Q

Fuel tanks should never be filled by cascading liquid through an open hatch or manhole because __________.

🔍 Key Concepts

• Static electricity and fuel transfer on vessels • Fire and explosion risks in vapor-laden spaces • Proper procedures for fueling through closed systems vs. open hatches

💭 Think About

• When fuel is poured from a height into a tank through an open hatch, what physical effects can be created between the falling fuel and the surrounding vapor-air mixture? • Among the choices, which directly relates to an immediate ignition or explosion hazard during the process of fueling, rather than a secondary or less likely problem? • Think about what the primary concern of safety regulations is when handling flammable liquids on board — which option addresses that most directly?

✅ Before You Answer

• Identify which option involves ignition source creation during fueling, not just a nuisance or housekeeping issue. • Consider how fuel vapors behave in a confined or semi-enclosed space and what can set them off. • Ask: Which consequence would regulations be most urgently trying to prevent in this specific fueling scenario?
