(1) The method of preparing and testing the

Dual electric priming should be used when dual

time blasting fuse is the same as in the assembly of

electric firing systems are not used. This consists of

nonelectric firing system. Follow paragraphs 5-4a, b,

one electric firing wire with two electric blasting caps

and c.

connected in parallel (fig. 5-26).
