Which outcome commonly arises when HCFC refrigerant leaks from HVAC system into flame acetylene torch?

💡 Explanation

When HCFC refrigerant leaks into an acetylene torch flame, thermal decomposition occurs, producing highly toxic phosgene gas because chlorinated hydrocarbons react in oxidizing conditions. Therefore, phosgene gas results, rather than corrosion, explosion, or temperature decrease which each involve different required reaction conditions.
