Self-Heating Material

AFMAN 24-204(I)/TM 38-250/NAVSUP PUB 505/MCO P4030.19H/ DLAI 4145.3 29 11 DECEMBER 2001 Self-Heating Material--This material, when in contact with air and without an energy supply, is liable to self-heat. Self-Reactive Material--At normal or elevated temperatures, this material is liable to undergo a strong exothermic reaction. Exothermic reaction can be caused by excessively high transport temperatures or by contamination. Service Pressure--This term refers to the authorized pressure marking on the container. For example, for a cylinder marked "DOT 3A1800" the service pressure is 12410 kPa (1800 psi). Shipping Activity--Unit, organization, or activity that originally offers a hazardous material into the Defense Transportation System. Shipping Paper--The Air Cargo Manifest which includes minimum hazardous material information as required by DoD 4500.32R. In the absense of an Air Cargo Manifest, the Shipper’s Declaration for Dangerous Goods form may serve as a shipping paper. Single Packaging--Nonbulk packaging other than a combination or composite packaging. HSpecial Approvals – An authorization issued by the appropriate authority for transport of certain hazardous materials. These approvals may be a Department of Transportation Exemption, Competent Authority Approval (CAA), or a Certification of Equivalency (COE). Special Form Radioactive Material--Radioactive material that satisfies the following conditions: - It must be either a single solid piece or be contained in a sealed capsule that can be opened only by destroying the capsule. - The piece or capsule must have at least one dimension not less than 5 mm (0.197 inch). - It must satisfy the test requirements of 49 CFR 173.469. Special form encapsulations designed according to the requirements of the DOT in effect on 30 June 1983 and constructed before 1 July 1985 may still be used. Special form encapsulations, either designed or constructed after 30 June 1985, must meet the requirements of 49 CFR 178.350. Specific Activity of a Radionuclide--The activity of the radionuclide per unit mass of that nuclide. The specific activity of a material in which the radionuclide is essentially uniformly distributed is the activity per unit mass of the material. HStabilized--The substance is in a condition that precludes uncontrolled reaction. Theis may be achieved by methods such as addition of an inhibiting chemical, degassing the substance to remove dissolved oxygen and inerting the air space in the package, or maintaining the sustance under temperature control. Subsidiary Risk--An additional hazardous property of a material other than the primary hazard as identified in table A4.1. Tactical--A tactical operation is the movement of personnel, equipment and supplies of an organization so they can accomplish their immediate military combat objective. Technical Name--A recognized chemical name or micro biological name currently used in scientific and technical handbooks, journals, and texts. Generic descriptions are authorized provided they readily identify the general chemical or micro biological group. Transport Index--The dimensionless number (rounded up to the first decimal place) placed on the label of a package to designate the degree of control to be exercised by the carrier during transportation. The transport index is determined by: - The number expressing the maximum radiation level in mSv/h at one meter (3.3 feet) from the external surface of the package.
