Ki 9173.124 (E) The Associate Administrator for Hazardous Materials Safety has deter- mined that the material does not present a hazard which is associated with a Division 4.1 material, (ii) Generic types. Division 4.1 self -re- active materials are assigned to a ge- neric system consisting of seven types. A self -reactive substance identified by technical name in the Self -Reactive Materials Table in §173.224 is assigned to a generic type in accordance with that table. Self -reactive materials not identified in the Self -Reactive Mate- rials Table in § 173.224 are assigned to generic types under the procedures of paragraph (a) (2) (ii I) of this section. (A) Type A. Self -reactive material type A is a self -reactive material which, as packaged for transportation, can detonate or deflagrate rapidly. Transportation of type A self -reactive material is forbidden. (B) Type B. Self -reactive material type B is a self -reactive material which, as packaged for transportation, neither detonates nor deflagrates rap- idly, but is liable to undergo a thermal explosion In a package. (C) Type C. Self -reactive material type C is a self -reactive material which, as packaged for transportation, neither detonates nor deflagrates rap- idly and cannot undergo a thermal ex- plosion. (D) Type D. Self -reactive material type D is a self -reactive material which— (1) Detonates partially, does not deflagrate rapidly and shows no violent effect when heated under confinement: (4 Does not detonate at all, deflagrates slowly and shows no violent effect when heated under confinement; or (3) Does not detonate or deflagrate at all and shows a medium effect when heated under confinement. (E) Type E. Self -reactive material type E is a self -reactive material which, in laboratory testing, neither detonates nor deflagrates at all and shows only a low or no effect when heated under confinement. (F) Type F. Self -reactive material type F is a self -reactive material which, In laboratory testing, neither detonates in the cavitated state nor deflagrates at all and shows only a low 49 CFR Ch. 1 (10-1-99 Edition) or no effect when heated under confine- ment as well as low or no explosive power. (G) Type G. Self -reactive material type G is a self -reactive material which, in laboratory testing, does not detonate in the cavitated state, will not deflagrate at all, shows no effect when heated under confinement. nor shows any explosive power. A type G self -reactive material is not subject to the requirements of this subchapter for self -reactive material of Division 4.1 provided that it is thermally stable (self -accelerating decomposition tem- perature is 50 'C (122 'F) or higher for a 50 kg (110 pounds) package). A self -re- active material meeting all character- istics of type G except thermal sta- bility is classed as a type F self -reac- tive, temperature control material. (iii) Procedures for assigning a self -re- active material to a generic type. A self - reactive material must be assigned to a generic type based on— (A) Its physical state (i.e. liquid or solid), in accordance with the defini- tion of liquid and solid in § 171.8 of this subchapter; (B) A determination as to its control temperature and emergency tempera- ture, If any, under the provisions of § 173.21(f) ; (C) Performance of the self -reactive material under the test procedures specified in the UN Recommendations on the Transport of Dangerous Goods, Tests and Criteria and the provisions of paragraph (a)(2)(iii) of this section; and (D) Except for a self -reactive mate- rial which is identified by technical name in the Self -Reactive Materials Table in §173.224(b) or a self -reactive material which may be shipped as a sample under the provisions of § 173.224, the self -reactive material Is approved in writing by the Associate Adminis- trator for Hazardous Materials Safety. The person requesting approval shall submit to the Associate Administrator for Hazardous Materials Safety the tentative shipping description and ge- neric type and— (1) All relevant data concerning phys- ical state. temperature controls, and tests results; or (2) An approval issued for the self -re- active material by the competent au- thority of a foreign government. 446
