(2) Chemical Group B (e.g., Phosgene, CN, CN-DM, BZ, CS, HC, etc.) shall include chemical
agents (gaseous, liquids, or solids) which are toxic or incapacitating by inhalation, ingestion
or percutaneous absorption. A suitable protective mask is required for the protection of
personnel against inhalation of vapors, particles, or smoke from burning agents. Since
these agents will cause varying degrees of skin irritation, approved types of protective
clothing (such as coveralls, protective masks, gloves, etc.) shall be provided and worn. This
group consists of choking agents, blood agents, riot control agents, and screening smokes.
(3) Chemical Group C shall include materials which are spontaneously combustible (WP and
PWP) and for which special fire fighting techniques and materials are required. Personnel
protection will be of the type that will provide protection against fire and heat. Toxic fumes
are a minimal hazard.
(4) Chemical Group D consists of signaling smokes and incendiary material (e.g., TH, IM, NP,
PTI) for which conventional fire fighting methods except use of water may be used.
Protection from inhalation of smoke from burning incendiary mixtures is required.
b. Chemical Munitions. The same group designation as is used for agents shall be used for
chemical munitions. The chemical and storage compatibility groups of the munition item shall
be the same as that of the chemical agent contained within the item.
c. Storage Requirements. The fencing and security requirements for any structure or storage area
must meet the criteria outlined in AR 50-6 and AR 190-11.
(1) Bulk containers of GB and VX agents and agent-filled items assembled with explosives
and/or propellants shall be stored in earth-covered magazines or other structures which
could be expected to offer a degree of protection and containment in the event of an
(2) Bulk one-ton containers of mustard (H series) agents may be stored out of doors on steel
dunnage if they are properly secured and if measures have been taken to prevent theft of
agent. The detailed procedures required for securing containers and preventing theft of
agent are available from AMCSS.
(3) Incendiary and pyrotechnic munitions (including riot control items designed for thermal
dissemination) - Smoke grenades, riot control grenades, and incendiary items shall be
stored in structures appropriate to their explosive classification as determined in Chapter 5
of TM 9-1300-206.
(4) Unassembled rounds -Projectiles, bombs, or other items filled with agents, but not
assembled with explosives or initiating components, shall be stored in approved type
(5) Table 4-2 of TM 9-1300-206 (see Figure 11, page 15) provides storage information and
shipping classifications. For additional information, see TM 3-250.
d. General Requirements.
(1) Chemical munitions or agents shall not be stored in magazines with floors which are made
of wood or other porous material in which agent may be absorbed, making decontamination
