In the presence of an open flame or hot surfaces, chlorinated fluorocarbon refrigerants decompose and form what chemical substance?

🔍 Key Concepts

• Refrigerant safety and toxicity in machinery spaces • What happens when chlorinated fluorocarbons (CFCs) contact high heat or open flame • Historical use of certain chemical warfare gases related to combustion of CFCs

💭 Think About

• Among the choices, which one is known to be associated with burning or decomposing refrigerants rather than normal combustion of fuel or normal air contents? • Which chemical in the list is historically recognized as a highly toxic gas once used in warfare, linked to burning certain chlorinated compounds? • Think about which options are ordinary by‑products of burning hydrocarbons (like fuel) versus a special hazardous product of refrigerant decomposition.

✅ Before You Answer

• Eliminate any choices that are normal combustion products (for example, what you commonly get when burning fuel or hydrocarbon-based materials). • Ask: which option is a chlorine-containing, highly toxic gas known in maritime safety training as a risk when refrigerant leaks contact flame? • Review refrigeration safety sections in your study material for warnings about CFC leaks near open flames or hot work and the specific gas they caution about.
