🔍 Key Concepts

• Firefighting in enclosed/closed spaces on ships • Dangers of smoke, toxic gases, and depleted oxygen after a fire is out • Requirements for a safe atmosphere before entry (gas-free / breathable air)

💭 Think About

• Is visibility alone a reliable indicator that the air is safe to breathe after a fire? • Can using special equipment (lifeline, explosion-proof flashlight) make an atmosphere safe if the air itself is still hazardous? • What conditions must be met regarding both toxic gases and oxygen levels before people can safely enter a compartment after a fire?

✅ Before You Answer

• Make sure you consider both the removal of toxic fumes and the presence of enough oxygen to support life. • Check whether "overhaul" addresses air quality or mainly deals with preventing re-ignition of the fire. • Verify which option directly mentions the condition of the atmosphere inside the compartment, not just equipment or visibility.
