      (33) "Misfire" means the complete or partial failure of a blasting charge to explode as planned.

      (34) "Overburden" means material of any nature, consolidated or unconsolidated, that overlies a deposit of useful materials or ores that are to be mined.

      (35) "Primer" or "booster" means a package or cartridge of explosives which is designated specifically to transmit detonation to other explosives and which does not contain a detonator.

      (36) "Qualified person" means, as the context requires:

      (a) An individual deemed qualified by the commissioner and designated by the operator to make tests and examinations; and

      (b) An individual deemed by the commissioner to be qualified by training, education, and experience to perform electrical work, to maintain electrical equipment and to conduct examinations and make tests of electrical equipment used at the mine for which he is assigned such responsibility.
