Guidelines for Use
Priming and Initiation
Viperdet MS Downline can be used to prime the full range of BME’s detonator-sensitive explosive products.
Viperdet MS Downline detonators can be sequentially delayed and initiated by Viperdet Trunklines.
Viperdet MS Downline can also be initiated by a single strand of detonating cord with a minimum core load of 5 g/m.
To prevent a snap, slap, and shoot incident (unexpected detonation) never pull or stretch non-electric shock tube to the point of breaking.
