🔍 Key Concepts

• Behavior of liquefied gas when it escapes (expansion, vapor cloud, flammability) • Basic firefighting priorities: stop the fuel, cool surroundings, then extinguish flames • Suitability of foam, water spray, and fuel shutoff for gas vs. liquid fires

💭 Think About

• Ask yourself: In any fire, which element of the fire triangle (fuel, heat, oxygen) is usually the most effective and safest to remove first when possible? • Consider whether you can safely attack the flames before stopping the flow of gas, or if that might allow more unignited vapor to accumulate. • Think about which extinguishing agents (foam, water, etc.) actually work on a gas fuel as opposed to a pool of liquid fuel.

✅ Before You Answer

• Verify whether foam and water spray are effective on a free-burning gas jet compared to a contained liquid pool fire. • Check standard shipboard emergency procedures for gas leaks and gas fires: what is listed as the first priority when it can be done safely? • Confirm that the option you choose deals directly with the source of the escaping gas rather than only with the visible flames.
