🔍 Key Concepts

• spontaneous combustion usually involves a slow chemical reaction that creates heat over time • materials that oxidize or decompose in confined spaces can self-heat • difference between a self-heating reaction and an external ignition source (sparks, open flames, smoking)

💭 Think About

• Which choice involves a material that can slowly heat up by itself without a spark or flame? • Which situations listed depend on an obvious outside ignition source, and which one could occur even when no one is around? • Think about what happens to certain cleaning materials or waste products if they’re left piled up with no ventilation.

✅ Before You Answer

• Identify which option involves stored materials in an enclosed space that can trap heat. • Eliminate options that clearly require an external ignition source like a spark, open flame, or lit cigarette. • Ask: In which situation could a fire realistically start with no person present and no obvious ignition source?
