Guidelines For Use

System Usage

The BME DCU operates independently of a vehicle power head. The DCU features a Model 2 mobile pump (MP2) that delivers emulsion and sensitizing solution simultaneously, forming an explosive upon entering the blasthole.

Its low energy requirements enable operation on various power sources, including an electric motor, air, or hydropower.

Safe Use

  • Never fight explosive fires.
  • Refer to Safety Data Sheet (SDS) for first aid information.
  • All explosives must be transported and stored in accordance to relevant regulations.
  • All explosives are classified as dangerous goods and may cause damage to property, personal harm, or death, if not used correctly.
  • Always keep products away from sources of heat, sparks, flame or hot surfaces and avoid mixing with combustibles or incompatible materials.
