What is a key characteristic of nerve agents?

Nerve agents are classified as potent chemical warfare agents designed to disrupt the normal functioning of the nervous system. One of their most critical characteristics is their rapid action. When exposed to these agents, individuals can experience immediate health effects, which may manifest within seconds to minutes depending on the dose and route of exposure. Symptoms can include pinpoint pupils, difficulty breathing, muscle twitching, and loss of consciousness.

This immediacy is a significant reason why nerve agents are often a focus in discussions about chemical threats. Their quick onset of action makes them particularly dangerous in both military and terrorist contexts, as they can incapacitate large numbers of individuals in a short period. This characteristic distinguishes them from many other agents that may have delayed symptoms or require longer exposure times for health impacts to become apparent.
