Abschnitt 1.5 - 1.5 Blasting
The dust particles which are generated during blasting constitute a large surface area and may lead to a fire hazard and the formation of a hazardous explosive atmosphere. A fire occurs if deposited dust ignites. The ignition of even small quantities of whirled up dust causes an explosion hazard.
Due to the high explosion risk and the simultaneous occurrence of ignition sources during machining, the generated dusts are usually led to a wet scrubber and separated. This induces a reaction of magnesium particles with water and the formation of such an amount of hydrogen gas that an explosive mixture may develop.
