Tear Gas
Tear Gas
Tear gas, also known as lachrymator agent or lachrymator (from the Latin lacrima meaning "tear"), is a chemical weapon that causes severe eye, respiratory, and skin irritation, pain, vomiting, and even blindness. In the eye, it stimulates the nerves of the lacrimal gland to produce tears. Common lachrymators include pepper spray (OC gas), Pava spray (nonivamide), CS gas, CR gas, CN gas (phenacyl chloride), bromine gas, and xylyl bromide, among others.
Pronunciation

Etymology
The term "tear gas" was first used in 1914 and is a translation of the French word "lacrymogène". It is derived from the Latin word "lacrima" which means "tear" and the Greek word "gennan" which means "to produce".
Usage
Tear gas is frequently used for riot control by law enforcement and military personnel. It is also used in warfare, although its use in warfare is prohibited by various international treaties, including the Chemical Weapons Convention.
