What is a potential health hazard of Ammonia at concentrations above the Permissible Exposure Limit?

Severe respiratory issues are a significant health hazard associated with ammonia exposure at concentrations exceeding the Permissible Exposure Limit (PEL). Ammonia is a corrosive substance that can irritate the respiratory tract, leading to conditions such as pulmonary edema, which is a serious accumulation of fluid in the lungs. At elevated levels, inhaling ammonia can cause coughing, difficulty breathing, and significant distress. Prolonged exposure may lead to more severe respiratory complications and long-term health effects, making it crucial for individuals working with or around ammonia to adhere to safety guidelines and PELs to mitigate these risks. Understanding this risk is critical for protecting workers' health in environments where ammonia is present.
