Blasting agent.

"Blasting agent" means a material or mixture: that consists of a fuel and oxidizer; that is intended for blasting but is not otherwise defined as an explosive; and that, as a finished product mixed for use or shipment, cannot be detonated by means of a number 8 test blasting cap, as defined in subpart 9a, when unconfined.

Subp. 3a.


"Commissioner" means the commissioner of the Department of Public Safety or designee of the commissioner.

Subp. 4.

Department of Transportation.

"Department of Transportation" means the United States Department of Transportation.

Subp. 4a.


"Detonator" means a device containing a detonating charge that is used for initiating detonation in an explosive. The term includes electric blasting caps of instantaneous and delay types, blasting caps for use with safety fuses, detonating cord delay connectors, and nonelectric instantaneous and delay blasting caps.

Subp. 5.

Explosive-actuated device.

"Explosive-actuated device" means a tool or special mechanized device that is actuated by explosives. Examples of explosive-actuated power devices are jet tappers and jet perforators. This term does not include propellant-actuated power devices.

Subp. 6.

For purposes of this subpart, there are three classes of explosive materials. These classes, together with the description of explosive materials comprising each class, are as follows:


High explosives are explosive materials that can be caused to detonate by means of a blasting cap when unconfined; for example, dynamite.


Low explosives are explosive materials that can be caused to deflagrate when confined, for example: black powder, safety fuses, igniters, igniter cord, fuse lighters, and special fireworks defined as class B explosives by United States Department of Transportation regulations in Code of Federal Regulations, title 49, part 173.


Blasting agents include, for example, ammonium nitrate-fuel oil and certain water gels.

Subp. 7.
