Large spills of refrigerants can cause suffocation because:

Refrigerants that spill in large amounts create an asphyxiation risk because the gas is heavier than air and tends to settle low in an enclosed space. As it clouds near the floor, it pushes breathable air upward and reduces the amount of oxygen available for people to breathe. Even if the gas isn’t highly toxic, the lack of oxygen can quickly lead to dizziness, fainting, or unconsciousness. The danger is about displacing air, not about the gas simply evaporating or being harmless; proper ventilation and evacuation are essential to prevent suffocation.
