Study · not a certificate
Skills for this trade.
179 items across 19 blocks. Every item has a note on this site — we do not send you to a third-party lecture as the lesson. Course 01 is the written-job path. Sign in to tick progress. We never teach charge design. Official licences stay with the issuer.
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.
course 01
Course 01 — The written job
Six lessons. You read. Sign in to tick. Not a certificate. The game is a different page.
course 02
Course 02 — The day's plan
Which machine, whose hours, what is due. You read. The game is a different page. Not a plant ticket.
course 03
Course 03 — The number
Take-off, mix, haul, dump, scrap. Every figure cites its basis. DemTools measures. We do not invent a rate.
