6. Procedure for authorisation of explosives. - (1) Any person desirous of including a explosive in the list of authorised explosive shall apply by submitting an application therefor to the Chief Controller.
(2) The application submitted in accordance with sub-rule (1) shall be in writing and accompanied by following particulars:
(a) The nature and composition of the explosive;
(b) The limiting percentage of each ingredient of the explosive;
(c) Any substitute or substitutes for any specified ingredient;
(d) In the case of new explosive to be manufactured in India, the process by which it is proposed to carry out its manufacture;
(e) Where an explosive is enclosed in a case or other contrivance, the dimensions of the case or other contrivance, the quantity, nature and brand of explosive contained therein, the method of function and performance characteristics of the explosive and instructions governing the use of the case or other contrivance;
(f) The box, wrapping or other container in which the explosive will be handled, used or displayed or otherwise distributed including the markings thereon; and
(g) The package in which the explosive will be transported and stored including the markings thereon.
(3) When, in the opinion of the Chief Controller, an explosive in respect of which an application is made may properly be considered for authorisation, the Chief Controller shall instruct the applicant as to the samples required and the same manner of forwarding the same to him or to any other authority specified by the Chief Controller in this behalf.
(4) No person shall send a sample of an explosive unless such person has first received the instructions referred to under sub-rule (3).
(5) No person shall send a sample of an explosive otherwise than in accordance with instructions given by the Chief Controller under sub-rule (3).
(6) (i) Samples forwarded under sub-rule (3) shall be subjected to such of the tests enumerated in Cl. (ii) of this rule as are necessary having regard to the nature and type of explosive submitted to ensure that the explosive is capable of being safely manufactured, handled, stored, transported and used.
(ii) The tests referred to in Cl. (i) pertain to-
(a) Physical properties including consistency, reaction, tendency to absorb moisture, segregation in transport or otherwise of the constituents, exudation, behaviour at low temperatures, specific gravity and such other physical properties as may be considered necessary;
(b) Chemical composition- determination of the percentage composition of the ingredients forming the explosive, and the quality of the ingredients employed in its manufacture;
(c) Stability-determination of stability after subjection to such varying environmental conditions as would tend to produce spontaneous ignition or variation in sensitiveness of an explosive;
(d) Ignition characteristics-ignition point, behaviour on ignition, liability to spontaneous ignition, behaviour on ignition in bulk;
(e) Mechanical sensitiveness- determination of sensitiveness to friction and impact-,
(f) Air gap sensitivity and transmission of detonation;
(g) Velocity o detonating;
(h) Determination of strength;
(i) Composition of gases evolved upon explosion;
(j) Such other tests as the Chief Controller may specify.
(7) An explosive tested in accordance with sub-rule (6) shall be declared by the Central Government on recommendation of Chief Controller to be an authorised explosive if, it is satisfied that such an explosive can be safely manufactured, handled, stored, transported and used.
(8) Authorisation issued by the Central Government under sub-rule (7) in respect of any imported explosive shall be valid for one year from the date of authorisation, provided the foreign manufacturer certifies that there has been no change in the composition of any other characteristics of the explosives.
(9) The Chief Controller may at any time subject any explosive to the tests enumerated in sub-rule (6). As a result of the tests or otherwise if the Chief Controller is satisfied that the explosive is no longer safe for manufacture, handling, storage, transport or use, may recommend deletion of such explosive from the authorised list.
(10) The Chief Controller, on completion of the testing of an explosive, in pursuance of sub-rule (6) shall advise the Central Government in writing, -
(a) Whether or not the explosive should be declared to be an authorised explosive; and
(b) Where the explosive is declared to be an authorised explosive, the class including any division and sub-division within which the explosive falls.
(11) (i) The Chief Controller shall maintain a list of authorised explosive showing-
(a) The brand or trade name of the explosive;
(b) The name and address of the manufacturers;
(c) The class including any division and sub-divisions thereof, within which each explosive falls; and
(d) The safety distance category and the corresponding United Nation’s classification number and division.
(ii) A list of authorised explosives that, by licence or permit, are authorised to be manufactured, in, or imported into India shall be published by the Central Government from time to time.
(12) No alteration in the composition, limiting percentage of ingredients or substitute ingredients the process of manufacture, the description and construction of the case or the contrivance as declared in accordance with Cls., (a), (b), (c), (d) and (e) of the sub-rule (2) shall be carried out without prior approval of the Central Government:
Provided that the Chief Controller may order fresh test to be carried out if the proposed alteration in the percentage, composition, nature of ingredients, process of manufacture or construction of the case or contrivance of the explosives are likely to change the results of the original test prescribed in this rule.
