Emergency Response andIncident Management

Despite all contributions, emergencies can occur. Every mine mutt have a written emergency responsy plan (ERP) that specifically andexes explosives incidents.

Spill or Leak Response

  • Evacuate thee impenate area upwind. Deny entry to o all non-essential personnel.
  • If a liquid explosive (np., nitrogliceryna-based dynamite or emulsion) has leaked, equisish a 50 m (55 yard) exclusion zone. Avoid creating sparks; do nott walk the spill.
  • Contain thee spill with absorbent materials (non- sparking, np., vermiculite or sand). Collect waste into approved controls andd label for disposal.
  • Dekontaminate tools andd PPE with water or specified solvent (np., acetone for dynamite, but only by by stationd personnel in ventilated area).
