🔍 Key Concepts

• Fire prevention measures during fuel transfer • How diesel fuel vapors behave and what ignition sources are • Typical bunkering (fueling) safety practices on small vessels

💭 Think About

• Which option directly reduces the chance of igniting fuel vapors? • Which choices seem unrelated to fueling or are used for other purposes in seamanship (day shapes, deck lighting, etc.)? • Think about what is usually posted or enforced around fuel docks and gas stations ashore—what common rule is always seen?

✅ Before You Answer

• Identify which option removes a source of ignition rather than trying to move fumes around • Eliminate any choices that deal with day shapes or navigation signals rather than fueling safety • Ask: Which precaution would a USCG inspector definitely expect to see enforced during fueling?
