Compatibility Group Letter

AFMAN 24-204(I)/TM 38-250/NAVSUP PUB 505/MCO P4030.19H/ DLAI 4145.3 23 11 DECEMBER 2001 Compatibility Group Letter--A designated alphabetical letter used to categorize different types of explosive substances and articles for stowage and segregation. Composite Packaging--Packaging consisting of an outer packaging and inner receptacle, so constructed that the inner receptacle and the outer packaging form an integral packaging. Once assembled it remains thereafter an integrated single unit; it is filled, stored, shipped, and emptied as such. Compressed Gas in Solution--A nonliquified compressed gas dissolved in a solvent. Consumer Commodity--A material that is packaged and distributed in a form intended or suitable for retail sale for puposes of personal care or household use. This does not include material designed for military or industrial use that is not readily available from commercial retail sources. Contingency--An emergency involving military forces caused by natural disasters, terrorists, subversives, or by required military operations. Due to the uncertainty of the situation, contingencies require plans, rapid response, and special procedures to ensure the safety and readiness of personnel, installations, and equipment. Conveyance--Any aircraft for the purposes of this manual. Crate--An outer packaging with incomplete surfaces. Cryogenic Liquid--A refrigerated liquefied gas having a boiling point colder than -90 degrees C (-130 degrees F) at 101.3 kPa (14.7 psi) absolute. A material meeting this definition is subject to requirements of attachment 6, regardless of whether it also meets the definition of a nonflammable, nonpoisonous compressed gas. The material is partially described as "(* * *), refrigerated liquid (cryogenic liquid)" in table A4.1, (with the asterisks replaced by the name of the gas). Cylinder--A pressure vessel designed for pressures higher than 40 psia and having a circular cross section. Depleted Uranium--Uranium containing less uranium 235 than the naturally occurring distribution of uranium isotopes. Dermal Toxicity--A material with an LD50 for acute dermal toxicity of not more than 1000 mg/kg. Design--The description of a special form material, a package, or a packaging, that enables those items to be fully identified. The description may include specifications, engineering drawings, reports meeting regulatory requirements, and other relevant documentation. HDiagnostic Specimens--A diagnostic specimen is any human or animal material including, but not limited to, excreta, secreta, blood, and its components, tissue, and tissue fluids, being shipped for purposes of diagnosis. Does not include live infected animals. Those specimens known to or expected to contain pathogens (microorganisms which cause infectious disease in humans or animals) must be shipped as a Class 6.2. Also, specimens transported for the purpose of screening or diagnosis for the presence of pathogens must be transported in the same manner. Live infected animals and diagnostic specimens known not to contain pathogens are not regulated by as a hazardous material. See Class 6.2 (Infectious Substances). Dilutent Type A--An organic liquid that does not damage the thermal stability or increase the hazard of the organic peroxide and with a boiling point not less than 150 degrees C (302 degrees F) at atmospheric pressure. Type A dilutents may be used for desensitizing all organic peroxides. Dilutent Type B--An organic liquid that does not damage the thermal stability or increase the hazard of the organic peroxide and with a boiling point, at atmospheric pressure, of less than 150 degrees C (302 degrees F) but at least 60
