🔍 Key Concepts

• Ro-Ro vessel cargo operations and who must be informed before starting systems • Why ventilation systems can affect both machinery spaces and deck operations • Company / safety procedures that require communication and coordination before changing ventilation status

💭 Think About

• Think about who is directly affected when cargo hold ventilation starts running and who must adjust equipment or operations in response. • Which department is responsible for power and machinery that supply the ventilation fans on a Ro-Ro vessel? • In practice, which people actually need this information to safely coordinate loading or discharging cargo?

✅ Before You Answer

• Verify which party controls or monitors the electrical load and machinery for the ventilation system. • Consider who needs to be aware to prevent unsafe buildup of exhaust, fumes, or gases during cargo operations. • Ask yourself if it is realistic or necessary to alert every option listed, or only the one(s) directly tied to the ventilation and cargo operation.
