🔍 Key Concepts

• flammable vapor vs. gas-free conditions in enclosed spaces like pumprooms • Difference between inerted cargo tanks and the atmosphere in the pumproom itself • Meaning of a gas-free certificate and where it applies on a tanker

💭 Think About

• Think about where the ignition risk actually exists: in the cargo tanks, in the pumproom atmosphere, or in the whole ship? • Which option describes a condition verified by tests of the air in the specific space where the tool will be used? • Does empty or inerted cargo tanks automatically guarantee there are no flammable vapors in the pumproom?

✅ Before You Answer

• Identify which choice refers specifically to the pumproom atmosphere rather than cargo tanks or entire vessel • Recall that a gas-free condition must be confirmed by gas testing for that exact space • Confirm that absence of liquid cargo does not necessarily mean absence of flammable vapors in adjacent spaces
