Q

Which of the following can result in an oxygen deficiency in a closed space?

🔍 Key Concepts

• Enclosed space hazards and why oxygen levels can drop • How oxidation (rusting) uses up oxygen in a confined area • How chemical reactions and decomposition from residues can affect air quality

💭 Think About

• In a closed space with no ventilation, what kinds of processes might slowly consume oxygen over time? • Could any of these options cause a chemical reaction that either uses up oxygen or releases gases that displace oxygen? • Think about whether more than one of these listed items is capable of affecting the breathable atmosphere.

✅ Before You Answer

• Check which items can chemically react with oxygen (oxidize) in a confined space. • Consider whether residues (cargo or fuel) can decompose or give off vapors that change the air composition. • Before choosing, ask: Is it only one, or could several of these mechanisms operate together in the same space?
