General Information

Sarin is a human-made chemical warfare agent that is classified as a nerve agent. Sarin is a clear, colorless, and tasteless liquid that has no odor in its pure form. Sarin, also known as GB, can evaporate into a vapor (gas) and spread into the environment. Sarin is not found naturally in the environment, but was developed in 1938 in Germany as a pesticide. Nerve agents, the most toxic and rapidly acting of the known chemical warfare agents, are similar to certain kinds of pesticides (insect killers) called organophosphates in terms of how they work and what kind of harmful effects they cause. However, nerve agents are much more potent than organophosphate pesticides.
