 Water Resistance Good Good to each cartridge.
 Fume Class IME1 & NRCan1e **Not for use • ALWAYS decouple the explosive charge when presplitting; that is, select larger
 underground borehole diameters to reduce borehole pressure. In surface applications, always stem
 to minimize air blast and plug the borehole above the explosive column to prevent
 stemming from filling the air/water space. In underground drifting applications, plug
 the borehole after the explosive column to prevent the explosive column from being
 ejected out of the borehole during detonation of the drift round.

DYNOSPLIT® TRANSPORTATION, STORAGE AND HANDLING
 • DYNOSPLIT must be transported, stored, handled and used in
Nitroglycerin Dynamite conformity with all applicable federal, state, provincial and local laws and regulations.
 • For maximum shelf-life, dynamite must be stored in cool, dry and well-ventilated
 magazines. Dynamite inventory should always be rotated by using the oldest materials
 first. For recommended good practices in transporting, storing, handling and using this
