Question 1 of 27070

CFC refrigerants exposed to high temperature or direct flame, will decompose and may produce what chemical substance?

🔍 Key Concepts

• Behavior of chlorofluorocarbon (CFC) refrigerants when exposed to extreme heat or open flame • Common toxic gases formed from burning halogenated refrigerants (those containing chlorine and fluorine) • Basic chemical composition of CFCs: which elements are present, which are not

💭 Think About

• Look at the elements in typical CFCs (chlorine, fluorine, carbon, sometimes hydrogen). Which option could realistically come from those elements when burned? • Ask yourself: when chlorinated or fluorinated compounds burn, what dangerous acidic gas is often a concern for crew safety and emergency response? • Which of the answer choices is known as a serious corrosive inhalation hazard associated with overheating or torching refrigerant lines?

✅ Before You Answer

• Eliminate any option that contains elements not present in CFCs (think: nitrogen, sodium, etc.) • Consider which product would form an acidic gas that can damage lungs and eyes when inhaled • Recall standard refrigeration safety training: what specific toxic gas is mentioned in connection with burning CFC or HCFC refrigerants?
