			 cap designed for and capable of being initiated by means of an electric
			 current.

			 means to connect with the ground to make the earth part of the
			 circuit.

			 person who works for wages or salary in the service of an employer.
(24) "Employer" means a person or
			 organization employing one (1) or more persons to work for wages or
			 salary.
(25) "Explosive" means any
			 chemical compound, mixture or device the primary or common purpose of which is

			 fulminate, and ammonium nitrate when mixed with a hydrocarbon plus high
			 explosive ingredients.
(26) "Face
			 or wall" means that part of any mine where excavating is progressing or was

			 capable of being easily ignited and of burning rapidly as defined by the
			 National Fire Protection Association.
(28) "Highway" means any public road or
			 travelway used by the general public.
(29) "Ignited cord" means a fuse, cordlike in
			 appearance, which burns progressively along its length with an external flame

			 "Inhabited building" means a building regularly occupied in whole or in part as
			 a habitation for human beings or any church, schoolhouse, railroad station,
