What is the primary danger to people near an accidental refrigerant release or spill?

  1. Blurred vision caused by the refrigerant vapor coming in contact with the eyes

  2. Changes in weather patterns caused by global warming

  3. Damage to the food chain caused by decreased ozone levels in the stratosphere

  4. Suffocation caused by the heavier refrigerant displacing oxygen in the air

The correct answer is: Suffocation caused by the heavier refrigerant displacing oxygen in the air

The primary danger to people near an accidental refrigerant release or spill is suffocation caused by the heavier refrigerant displacing oxygen in the air. Many refrigerants are denser than air, which means that when they are released, they can accumulate in low-lying areas. This accumulation reduces the concentration of breathable oxygen, posing a serious risk to anyone in the vicinity. In confined spaces or enclosed environments, this scenario can lead to potential asphyxiation, where individuals may not be able to get enough oxygen for respiration. It is crucial to understand this risk for safety measures and to take appropriate precautions in the event of a refrigerant leak.
