Three main types of fires make up Marine fire events. The first type starts on a single boat in a marina. These fires are usually electrical in origin and start small. Over time and if not detected, the fire spreads to surrounding boats. The second type occurs in open water. It usually starts as a small fire in the engine compartment, easily undetected by the crew. By the time the fire is discovered, it is often too late to extinguish. The third and most common type of marine fire is caused by gasoline vapor, resulting in a rapid explosion usually during or after refueling. Marine fires and explosions can cause significant damage.
