Explosives Regulations (C.R.C., c. 599)

17. When, in the opinion of the Chief Inspector, an explosive in respect of which an application is made may properly be considered for authorization, and is such as may, under regulations then in force, be forwarded by railroad or other available means of conveyance, the Chief Inspector shall instruct the applicant as to the samples required and the manner of forwarding them.

18. No person shall send a sample of an explosive to the Chief Inspector unless such person has first received the instruction referred to in section 17.

19. No person shall send a sample of an explosive to the Chief Inspector otherwise than in accordance with instructions given by the Chief Inspector pursuant to section 17.

• 20. (1) Samples forwarded to the Chief Inspector under section 17 shall be subjected to such of the tests enumerated in subsection (2) as are necessary or desirable, 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.

• (2) The tests referred to in subsection (1) are as follows:

  • (a) physical properties — including consistency, reaction, absorptive power for 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 — ignition point, behaviour on ignition, liability to spontaneous ignition, behaviour on ignition in quantity;

  • (e) mechanical sensitiveness — determination of sensitiveness to friction and impact;

  • (f) detonation by influence;

  • (g) velocity of detonation;

  • (h) determination of strength;

  • (i) composition of gases evolved upon explosion;

  • (j) such other tests as the Chief Inspector may specify.

21. The Chief Inspector may at any time subject any explosive to the tests enumerated in section 20.

• 22. (1) An explosive tested in accordance with section 20 shall be declared by the Chief Inspector to be an authorized explosive if, as a consequence of the tests to which it has been subjected, he is satisfied, having regard to the nature and type of the explosive, that it is capable of being safely manufactured, handled, stored, transported and used.

• (2) The Chief Inspector may declare an explosive that is named in a General Explosives Importation Permit to be an authorized explosive during the term of the permit if, as a consequence of the tests to which the explosive has been subjected, the Chief Inspector is satisfied, having regard to the nature and type of the explosive, that it is capable of being safely handled, stored, transported and used.
