🔍 Key Concepts

• Tank cleaning safety procedures in cargo and ballast tanks • Risk of static electricity and flammable vapors during hose connection/disconnection • Requirement that equipment be removed from hazardous space before breaking any connections

💭 Think About

• In which situation would disconnecting a hose most reduce the chance of igniting vapors inside the tank? • What could happen if a leak or spark occurred at the hose coupling while the machine was still in the tank? • Which option best matches the idea of keeping ignition sources and openings outside the tank atmosphere when breaking connections?

✅ Before You Answer

• Confirm which option places the actual disconnect point outside the tank environment • Eliminate any choices where the hose or machine is still in direct contact with the tank atmosphere during disconnection • Verify that the chosen condition would minimize leaks, spray, and sparking inside the tank
