saline solution, calcium chloride, and distilled water, for example, are assigned NSNs in FSC
6800 (Chemicals), but are handled as low hazard material under normal storage and handling
2. Low-risk explosive materials should be packaged and labeled in accordance with UN
division 1.4S and 1.6 explosives. These substances and articles present only a small hazard in
the event of ignition during transportation. The effects are largely confined to the package, and
no projection of fragments of appreciable size or range is expected. When exposed to external
fire, virtually instantaneous explosion of most of the package's contents must not occur.
3. Materials which have been grouped as "general" miscellaneous hazardous materials (V1,
V5, V6, and Z series, except Z6) may be stored in low hazard general purpose storage areas.
4. Under certain circumstances individual services or agencies may allow small quantities of
selected hazardous materials to be stored in general purpose storage areas when a specific
mission may otherwise be adversely impacted. The risk to be avoided in these situations is the
one encountered through the accumulation of small quantities of these miscellaneous hazardous
materials in sufficient quantities to create a high risk storage situation. In addition local, state,
and federal occupational and environmental regulations must be followed. The decision to
deviate from these guidelines should be situation specific and the decision process fully
documented and coordinated. Paragraph 4.20 provides recommendations for storage under these
circumstances as they relate to the Hazard Characteristic Codes.
C. Basic Requirements. Since the materials are assigned a low risk hazard classification, they
may be stored in a general purpose (i.e. low hazard) warehouse.
D. Applicable HCCs. The following HCCs should be stored in storage type L:
1. C3, Acid, Low Risk.
2. B3, Alkali, Low Risk.
3. E2, Explosive, Low Risk (alternatively may be stored in an explosive area (type E) if space
4. M1, Magnetized Material.
5. N1, Not Regulated as Hazardous
6. T4, Poison, Food Contaminant.
7. T5, Pesticide, Low Risk.
8. T6, Health Hazard.
9. V1, Miscellaneous Hazardous Materials Class 9.
