Final answer:
Irritants are chemical agents that cause temporary, usually non-fatal, irritation to the skin, eyes, and respiratory tract, with chloropicrin being an example.
Step-by-step explanation:
The type of chemical agent that causes temporary, usually non-fatal, irritation of the skin, eyes, and respiratory tract is known as an irritant. An example of such a compound is chloropicrin, which is also known for its pesticidal properties. These substances, which can also include household products like hydrogen peroxide, provoke a reactive response upon exposure, leading to discomfort or pain in the affected tissues. They can cause a variety of symptoms such as tearing, redness, and inflammation. Unlike corrosive substances like hydrochloric acid that can cause permanent damage, irritants typically induce reversible effects if the exposure is not prolonged or the concentration is not excessively high.
