Secondary containers shipping

Refrigerators used for storage of flammable chemicals must be explosion-proof, laboratory-safe units. Materials placed in refrigerators should be clearly labeled with water-resistant labels. Storage trays or secondary containers should be used to minimize the distribution of material in the event a container should leak or break. It is good practice to retain the shipping can for such secondary containers. 

If dry ice is used to keep the shipment cold, it must be placed outside the secondary container. The shock-absorbing material must then be arranged so that the secondary container will not become loose inside the shipping container as the dry ice sublimes. The shipping container must be labeled with the quantity of dry ice packed, the date of packing, and the DOT transportation classification for dry ice, ORM-A (see Figure App. 3.8). 

The committee s study of site-specific secondary waste practices and requirements focused on the six major waste streams produced by the chemical agent disposal operations. Of the six, brine and brine salts are treated and disposed of off-site during operations at permitted treatment, storage, and disposal facilities. At the Umatilla site, brine solutions are thermally treated to produce a solid salt, which is then shipped off-site to a hazardous waste landfill. However, brine solution may be disposed of off-site if thermal treatment to produce a brine salt impedes the main mission of the agent disposal operation. Brine and brine salts must meet the established waste control limit for off-site disposal—that is, the agent concentration must be below the permit limit for materials containing agent. 

Chemical entities from the storage environment (i.e., very secondary packaging components), such as volatiles from cardboard shipping containers or plastic storage bags. 

MAPS and PBNSF will also have components for unpacking and characterization of NSCWM, mechanical accessing of the chemical agent in munitions or containers, and explosive destruction of energetics. Secondary wastes from the neutralization process may be destroyed on-site or shipped off-site for treatment.
