Gas and Fume Generation at the Blast Site

• Description:
  Gases and fumes are generated as a result of explosives detonation at a blast site. This chapter discusses only those gases produced by the detonation of commercial explosives. Since fracturing of the rock has potential to allow these detonation gases to either (1) accumulate in the muckpile or (2) migrate out of the blasted area, they should be ventilated as soon as possible. Underground operations install ventilation systems to exchange the air, but surface operations rely on natural ventilation to the open air. To facilitate the ventilation, the blaster-in-charge should encourage early muckpile excavation to avoid any potential of accumulation of detonation gases. [Description provided by NIOSH]
