#12 strength and #8 strength refers to the base charge of a detonator.
Historically detonators were made in a range of strengths, #6 for underground coal (Carrick Detonators) and #8 for initiating gelatin dynamite. With the change to less sensitive explosives a stronger detonator was required so ICI / Orica made a #8* which is equivalent to a #12 strength DYNO detonator.
There were also #2, #3, #4 detonators but these were for testing the sensitivity of explosives and were not used for blasting.
These units of competency are recommended for current Drill and Blast Engineers, Superintendents, Supervisors and Senior Shotfirers wishing to increase both their design and management skills.
Course assessment is by completion of classroom and online components and by assignment submission.
Class size is limited to eight persons on a first come basis.
