Some chlorinated fluorocarbon refrigerants may decompose into a toxic irritating gas under what conditions?
• CFC refrigerant safety data and decomposition products • Effects of high temperature on refrigerants and what gases they can form • Typical storage and handling requirements for refrigerant cylinders
• Under which condition would a chemical be most likely to break down into different substances? Think about energy/heat. • Which options describe normal, safe practices with refrigerants, and which describe abnormal or dangerous exposure? • For each choice, ask yourself: does this situation commonly appear in safety warnings about refrigerants producing toxic gases?
• Check which option clearly involves high heat or combustion. • Eliminate any options that describe standard, acceptable practices with refrigerants. • Recall that CFC safety warnings often mention formation of a toxic gas similar to phosgene—when does that typically form?
