Chemical agents nonpersistent

Persistence. Chemical agents may be divided into two main categories that describe how long they are capable of producing casualties persistent and nonpersistent. Chapter 3 from FM 3-7 has 12 charts of unmasking times for various agents in different situations. 

Mask-Only Command Only the protective mask is worn. The mask-only command is given in these situations 1. When riot control agents are being employed and no chemical or biological threat exists. 2. In a downwind vapor hazard of a nonpersistent chemical agent. The mask-only command is not appropriate when blister agents or persistent nerve agents are present. 

In addition to the chemicals included on the other lists, the CDC also included heavy metals such as arsenic, lead, and mercury volatile solvents such as benzene, chloroform, and bromoform decomposition products such as dioxins and furans polychlorinated biphenyls (PCBs) flammable industrial gases and liquids such as gasoline and propane explosives and oxidizers and all persistent and nonpersistent pesticides. Agents included in this volume are limited to those that are most likely to pose an acute toxicity hazard. 

This material has been used by the military as a simulant of a nonpersistent agent to evaluate chemical equipment. It is also used to activate detector kits and alarms. It has been used during field exercises to simulate the threat posed by toxic agent vapor and assist in training soldiers on the proper use of protective equipment. 

Chemical/Pharmacetical/Other Class Soman is a human-made nonpersistent anticholinesterase compound or organophosphate (OP) nerve agent, irreversible cholinesterase inhibitor, and chemical warfare agent. It is a light liquid with a camphorlike odor. 

H Type of burst Type of agent/type of burst P (persistent), NP (nonpersistent) Nuclear Specify air, surface, or subsurface. Chemical State 1 whether air, ground, or spray attack. j... 

Pyridine has long been used as a solvent in the production of rubber chemicals, textile water-repellant agents, and in the synthesis of drugs. The derivatives 2-benzylpyridine and 2-aminopyridine are used in the preparation of antihistamines. Another market for pyridine is in the manufacture of the nonpersistent herbicides diquat and paraquat.
