Chlorine gas concentrations above 1,000 ppm are associated with which outcome?

Explanation:
Chlorine gas at very high concentrations acts as a powerful inhalation toxin. It irritates and damages the airways and lungs so quickly that gas exchange can fail, leading to rapid pulmonary edema and suffocation. When concentrations exceed about 1,000 ppm, the injury from a few breaths can be fatal, especially if exposure isn’t stopped. The other properties—being flammable or explosive—do not apply to chlorine gas in this context, so those options don’t fit. The danger here is the immediate, life-threatening toxic effect on the respiratory system.
