🔍 Key Concepts

• Static electricity hazards during helicopter refueling operations • Special design/safety requirements for fuel transfer hoses on vessels per 46 CFR • Difference between controlling ignition sources versus controlling fuel spray or vapors

💭 Think About

• Which feature directly prevents a spark from jumping between the hose/helicopter and the vessel during fuel transfer? • Which options are more commonly associated with truck or car fueling stations, and which is specifically emphasized in maritime helicopter refueling rules? • Think about what happens as fuel moves through a hose at high speed — which safety device is intended to manage that specific risk?

✅ Before You Answer

• Verify in 46 CFR what each fuel hose used for helicopter refueling is required to be equipped with • Ask: which option is focused on electrical safety rather than just convenience or pollution control? • Eliminate any answers that primarily deal with vapor emissions control at shoreside facilities rather than shipboard helicopter fueling.
