🔍 Key Concepts

• Fueling safety procedures and typical best practices when tanks are nearly full • How overflow, venting, and sounding are used to prevent spills • The difference between controlling flow rate and blocking or trapping pressure

💭 Think About

• When you are ‘topping off’ a fuel tank, what is the biggest risk you’re trying to prevent, and how do you monitor it? • Which option describes an action that helps you know how full the tank is, rather than just assuming it’s okay? • Which choices might actually increase the chance of overpressure, hidden leaks, or missed warning signs during fueling?

✅ Before You Answer

• Identify which option mentions frequent checking/measurement of tank level instead of just closing something off. • Check which action would help you slow the fuel flow safely without creating overpressure or hiding problems. • Make sure the chosen option would reduce the chance of spills and give the operator more awareness of the tank level during topping off.
