In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.

A recent chlorine gas leak in Pune, India, landed 20 individuals in the hospital. [9] Though that was an accidental exposure, chlorine gas has been used as a weapon of warfare since ...
Microscopic section of human lung from phosgene shell poisoning from An Atlas of Gas Poisoning, 1918. The deficiencies of chlorine were overcome with the introduction of phosgene, which was prepared by a group of French chemists led by Victor Grignard and first used by France in 1915. [32]
Chloracne is an acneiform eruption of blackheads, cysts, and pustules associated with exposure to certain halogenated aromatic compounds, such as chlorinated dioxins and dibenzofurans. [1] The lesions are most frequently found on the cheeks, behind the ears, in the armpits and groin region.

[11] The symptoms of acute nitrogen dioxide poisoning is non-specific and have a semblance with ammonia gas poisoning, chlorine gas poisoning, and carbon monoxide poisoning.
