The characteristic commonly associated with chemical agents is the rapid onset of medical symptoms. Chemical agents, which encompass a wide range of substances including nerve agents, blister agents, and choking agents, are designed to have immediate and severe effects on the human body. When a person is exposed to a chemical agent, symptoms can present within minutes to hours, depending on the type and concentration of the agent used.

This rapid onset is crucial for understanding the potential impact of chemical warfare or terrorist attacks, as it necessitates immediate medical response and swift public safety measures. In contrast, some other agents, such as biological agents, may have a delayed onset of symptoms, which can complicate recognition and response efforts. The ability to quickly identify and respond to chemical exposure is vital for effective emergency management and public health responses.
