Blast demolition of structures
Same rule. Charge, spacing, and the cut are never our course.
Study notes. Not a certificate. Not a licence. Not NEBOSH, PESO, ISEE, or IDE. We never design the charge, spacing, or the cut. Site hours and statutory papers have no video substitute.
Method selection: mechanical vs blast vs hybrid vs deconstruction. Knowing when *not* to blast is the senior skill.
We will not teach this. Charge, spacing, burden, cut geometry, explosive formulation, initiation design — licensed people and the named issuer where you work. This line is on the map so you know the skill exists. It is not a lecture and not a recipe.
