§ 121.7 - Chemical agents.

A chemical agent in Category XIV(a) is a substance having military application which by its ordinary and direct chemical action produces a powerful physiological effect. The term “chemical agent” includes, but is not limited to, the following chemical compounds:

(a) Lung irritants:

(1) Diphenylcyanoarsine (DC).

(2) Fluorine (but not fluorene).

(3) Trichloronitro methane (chloropicrin PS).

(b) Vesicants:

(1) B-Chlorovinyldichloroarsine (Lewisite, L).

(2) Bis(dichloroethyl)sulphide (Mustard Gas, HD or H).

(3) Ethyldichloroarsine (ED).

(4) Methyldichloroarsine (MD).

(c) Lachrymators and tear gases:

(1) A-Bromobenzyl cyanide (BBC).

(2) Chloroacetophenone (CN).

(3) Dibromodimethyl ether.

(4) Dichlorodimethyl ether (ClCi).

(5) Ethyldibromoarsine.

(6) Phenylcarbylamine chloride.

(7) Tear gas solutions (CNB and CNS).

(8) Tear gas orthochlorobenzalmalononitrile (CS).

(d) Sternutators and irritant smokes:

(1) Diphenylamine chloroarsine (Adamsite, DM).

(2) Diphenylchloroarsine (BA).

(3) Liquid pepper.

(e) Nerve agents, gases and aerosols. These are toxic compounds which affect the nervous system, such as:

(1) Dimethylaminoethoxycyanophos-phine oxide (GA).

(2) Methylisopropoxyfluorophosphine oxide (GB).

(3) Methylpinacolyloxyfluoriphos-phine oxide (GD).

(f) Antiplant chemicals, such as: Butyl 2-chloro-4-fluorophenoxyacetate (LNF).
