characteristics of the nonradioactive form of the same compound. Radioactive materials may be
expected to melt, vaporize, become airborne, or oxidize under fire conditions. The principal
reason radioactive materials are sealed is to prevent the spread of contamination. A sealed
source may burst if its contents are subject to fire. Under these conditions, it is conceivable that
certain radioactive materials might be oxidized to a radioactive dust or smoke. In addition, such
radioactive commodities may lose their integrity during storage and use, possibly releasing
radioactive material and creating a potentially hazardous situation.
C. Applicable HCCs. The following HCC should be stored in storage type A:
1. A1, Licensed Radioactive Material (gamma, alpha, or beta emitters) (except depleted
uranium (DU) munitions).
2. A2, Radioactive Material, License Exempt.
3. A3, Radioactive Material, License Exempt, Authorized.
D. Storage Arrangement. Areas used for the storage of radioactive materials shall be kept to
the minimum needed for adequate control. Radioactive materials shall not be stored in the same
warehouse section with explosives, flammable materials, photosensitive items (e.g., photographic
film), food products, or other incompatible commodities. An exception applies for DU
munitions which are stored as conventional ordnance. Smoking, eating, and drinking shall be
prohibited in areas where radioactive materials are stored and handled. Commodities that
contain radioactive gases or radium should be stored in well-ventilated structures.

4.10 DoD Storage Type C: Corrosive Material Storage
A. Purpose. This area should be used to store liquid or solid materials classified by UN class 8
as corrosive materials. These materials may, in addition to being corrosive, be either acidic or
alkaline.
B. Hazard Considerations. Materials packaged and labeled as corrosive have a destructive
effect on tissue and a corrosive effect on both steel and aluminum. It should be noted that, on
packages labeled as corrosive for transportation, no distinction is made between acidic or
alkaline materials. Corrosive solutions are measured by their pH value. A value of 1 up to 7
