AFMAN 24-204(I)/TM 38-250/NAVSUP PUB 505/MCO P4030.19H/ DLAI 4145.3 25 11 DECEMBER 2001 oxidizers and organic peroxides (Class 5), poisons and infectious substances (etiologic agents) (Class 6), radioactive materials (Class 7), corrosive materials (Class 8), and miscellaneous dangerous goods (Class 9). Hazard Zone--One of four levels of hazard (hazard zones A through D) assigned to gases and one of two levels of hazard (hazard zones A and B) assigned to liquids that are poisonous by inhalation.  A hazard zone is based on the LC50 value for acute inhalation toxicity of gases and vapors. Hazardous Materials Inspectors--DoD personnel whose duties require them to review the integrity of the packaging and  accuracy  of  documentation  for  all  hazardous  materials  being  transported  within  the  Defense  Transportation System (DTS) or by commercial carriers. Hazardous Materials Preparers--DoD personnel whose duties require them to sign legally binding documentation certifying that hazardous materials are properly classified, packaged, marked and labeled, and in all respects meet the legal requirements for transportation within the DTS or by commercial carriers. Hazardous Materials--A substance or material that is capable of posing an unreasonable risk to health, safety, and property when transported and has been so designated by this manual.  May also be referred to as hazardous cargo or dangerous goods.  NOTE:   For identification, listing and rules pertaining to hazardous WASTE, refer to Title 40 CFR, Parts 260-265, Protection of Environment, established by the U.S. Environmental Protection Agency (EPA). Hazardous   Substance--A   material,   including   its   mixtures   and   solutions,   that   meets   ALL   of   the   following conditions: - Listed in table A4.3 as originated in Appendix A to 49 CFR 172.101. - In a quantity, in one package, which equals or exceeds the reportable quantity (RQ) listed in table A4.3. - When in a mixture or solution: - For radionuclides, conforms to paragraph 6 of the appendix to 49 CFR 172.101. - For   other   than   radio   nuclides,   is   in   a   concentration   by   weight   which   equals   or   exceeds   the concentration corresponding to the RQ of the material shown in figure A1.1. Figure A1.1.  Quantity Required To Be a Hazardous Substance Mixture or Solution.

Highway Route Controlled Quantity--A quantity within a single package that is over 3,000 times the A 1 ^(Special Form)  or  A₂  (Normal  Form)  value  of  the  radionuclides  specified  in  A11.4;  or  over  1000  TBq  (27,000  Ci), whichever is least. Inert Solid--A solid that does not damage the thermal stability or increase the hazard of the organic peroxide. Inhalation Toxicity: - A  dust  or  mist  with  a  lethal  concentration  where  50  percent  of  the  test  subjects  die  (LC50)  from  acute toxicity on inhalation of not more than 10 mg/L.
