🔍 Key Concepts

• Combustion in enclosed spaces – what fire does to the air inside a sealed room or compartment • Oxygen consumption – which gas is used up as material burns, and what replaces it • Toxic / inert atmospheres – why breathing can be dangerous even if the fire is out

💭 Think About

• When a fire burns in a closed space with no ventilation, which gas in the air is mainly used up by the fire? • If that gas is used up, what condition does that create for anyone trying to breathe inside the compartment? • Look at each option: which one directly affects your ability to breathe normal air and remain conscious?

✅ Before You Answer

• Verify which gas is essential for human respiration and is reduced during a fire • Consider whether the compartment air would have more of the listed gas, or simply less oxygen • Ask yourself: which option most clearly describes a life‑threatening breathing hazard after a fire in a sealed space?
