Applicable HCCs

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

conditions.

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

is available).

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.
