🔍 Key Concepts

• Enclosed space / tank fire hazards (limited oxygen, vapor explosions) • Difference between containing a fire and extinguishing it • How CO₂ and water behave when discharged into spaces with flammable vapors or heated surfaces

💭 Think About

• Before you try to put the fire out, what must you prevent from happening inside that tank (think: air flow, vapor release, and pressure)? • Which action could dangerously stir up vapors or spread flame paths inside the tank instead of stabilizing the situation? • Which option represents a control/containment step, and which represent active firefighting steps that might come later?

✅ Before You Answer

• Identify which choices involve introducing energy or disturbance into the tank (pressure from hoses, spray patterns, gas discharge). • Consider which action reduces air supply and vapor escape paths before you begin extinguishing. • Ask: in a possible confined flammable vapor situation, what is the safest first priority—cooling, smothering, or containment?
