Which type of hazard is a choking agent classified as?

A choking agent is classified as a chemical hazard because it pertains to substances that can cause harm through their chemical properties upon exposure. Choking agents are toxic chemicals that act primarily on the respiratory system, causing a sensation of suffocation or difficulty in breathing, which can lead to serious health consequences. These agents disrupt normal oxygen exchange, leading to asphyxiation.

Chemical hazards encompass a wide range of substances that can be harmful to biological systems, including inhalation of toxic gases that may not only choke but also damage lung tissues or other organs. Understanding the nature of choking agents as chemical hazards is crucial for responders to accurately assess risks during a hazardous materials incident and implement appropriate safety measures.
