🔍 Key Concepts

• Sour crude (crude oil with significant hydrogen sulfide content) and how it affects tank atmosphere and residues • The meaning of pyrophoric oxidation and why certain residues can heat up or ignite when exposed to air • Typical safety concerns during gas-freeing and tank-cleaning operations on tankers

💭 Think About

• Think about what happens to iron sulfide or scale deposits in tanks that have carried sour crude when air is introduced during gas freeing. • Which option describes a hazardous reaction that would directly affect the safety of gas-free operations, rather than just a procedural or equipment change? • Ask yourself which choice involves a risk of heat generation or ignition related to oxidation processes.

✅ Before You Answer

• Verify which option clearly involves oxidation causing heat or ignition risk inside the tank structure. • Check which answers are about administrative/operational changes (more time, different crude, extra scrubber) versus a physical/chemical reaction in the tank. • Confirm that you know the usual role of scrubbers (what gas they treat and where they are installed) and whether pyrophoric oxidation is normally solved by adding another scrubber.
