🔍 Key Concepts

• Purpose of a wooden plug in a tank vent on a damaged tank • How tank venting affects pressure when liquid is being moved • Safety priorities during fire, flooding, and cargo transfer operations

💭 Think About

• In which situation would pressure in the damaged tank need to change freely rather than be restricted? • When liquid is pumped out of or into a tank, what happens if the tank cannot vent properly? • Which of the options involves directly changing the liquid level in the damaged tank?

✅ Before You Answer

• Identify which choice directly involves moving liquid into or out of the damaged tank • Ask whether a plugged vent could cause dangerous pressure or vacuum in that scenario • Eliminate options where venting the damaged tank is not immediately required for the action described
