Chlorine gas poisoning is an illness resulting from the effects of exposure to chlorine beyond the threshold limit value. Acute chlorine gas poisoning primarily affects the respiratory system, causing difficulty breathing, cough, irritation of the eyes, nose, and throat, and sometimes skin irritation. Higher exposures can lead to severe lung damage, such as toxic pneumonitis or pulmonary edema, with concentrations around 400 ppm and beyond potentially fatal. Chronic exposure to low levels can result in respiratory issues like asthma and chronic cough. Common exposure sources include occupational settings, accidental chemical mixing, and industrial accidents. Diagnosis involves tests like pulse oximetry, chest radiography, and pulmonary function tests. Treatment is supportive, with no antidote, and involves oxygen and bronchodilators for lung damage. Most individuals with mild exposure recover within a few days, though some may develop long-term respiratory issues.
