A concentration of 2,000 ppm (parts per million) of ammonia gas is considered potentially fatal to humans due to its highly toxic nature. Ammonia is a corrosive chemical that can lead to severe respiratory distress, lung damage, and other serious health issues when inhaled at high concentrations. At levels around or above 2,000 ppm, the gas poses an acute hazard, as it can rapidly overwhelm the body's ability to breathe and protect its tissues.

Understanding the harmful effects of lower concentrations is also important. For instance, lower levels, such as 500 ppm, can cause irritation to the eyes, skin, and respiratory tract, while concentrations in the range of 1,000 ppm may result in significant respiratory problems and even potentially life-threatening conditions with extended exposure. Thus, the focus on 2,000 ppm as a critical threshold underscores the need for immediate action and caution when dealing with ammonia in industrial or laboratory settings, reinforcing safety protocols to prevent exposure to such hazardous levels.
