DoD Storage Type C: Corrosive Material Storage

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
