← TechnologyWhich outcome occurs when R-410A refrigerant leaks from a split-system air conditioner in a closed room?
A)Reduced oxygen concentration displaces air✓
B)Increased flammability creating explosive hazard
C)Stratospheric ozone layer damage accelerated
D)Thermal decomposition emitting phosgene gas
💡 Explanation
When R-410A leaks, the higher density refrigerant displaces air because its molecular weight is greater than air, effectively reducing oxygen concentration. Therefore, reduced oxygen occurs, rather than increased flammability, ozone damage (older refrigerants), or phosgene production (requires high heat).
