Chlorine and Phosgene are known as?

Chlorine and Phosgene are classified as choking agents because they primarily affect the respiratory system. These chemicals cause immediate irritation of the mucous membranes and damage to the lungs, leading to respiratory distress. Chlorine, for instance, has a sharp, pungent odor that can signal its presence and prompt an immediate reaction from exposed individuals. Phosgene, although less noticeable due to its delayed effects, can cause severe pulmonary injury.

Coughing, choking, and difficulty breathing are characteristic symptoms of exposure to these agents, which is why they are identified specifically as choking agents. Other classifications like blood agents, blistering agents, or pathogens refer to different types of chemical agents that affect the body in other ways, such as causing systemic toxicity, skin blisters, or biological infections, respectively.
