Who it is for
Shift leads, new technicians, and owner-operators running air-cooled or hybrid crypto mining farms in Korea. Teams of two to four from the same site learn fastest because they can assign roles during drills.
What you leave with
- A marked fire-route sketch for a sample aisle, adaptable to your floor
- An airflow zone worksheet: intake, exhaust, recirculation traps
- Documented handling sequence for board and PSU swaps
- Instructor notes on the three highest-risk habits observed in class
Included
Classroom briefings, supervised drills on demo racks, printed worksheets, tea and light lunch both days, and a follow-up email summarizing your group’s action items. Gloves and ESD mats are provided during labs.
Not included
Travel to Yesan, lodging, certification exams from third parties, or redesign of your electrical service. We do not sell mining hardware or run hosted mining.
Process
- Register with preferred dates and a short note on cooling style.
- Receive confirmation, address details, and a pre-read on farm vocabulary.
- Day one: fire sources, extinguisher placement, egress drills, thermal walk.
- Day two: airflow zoning, board/PSU handling labs, group action plan.
- Optional: book an on-site walkthrough within 60 days for a travel fee.
Duration & place
Two consecutive weekdays, 09:30–16:30, at our loft near 165-11,Naeryangri,Oga-myeon,Yesan-gun,Chungcheongnam-do,Korea. Maximum eight seats so instructors can coach at the rack.
Preparation
Wear closed-toe shoes. Bring a rough floor sketch if you have one. Photograph any cable nests or blocked returns you want feedback on — faces and farm names can be blurred.
Constraints
Sessions run in English. We pause for Korean clarifying questions, but materials are English-first. The class assumes basic familiarity with miners and PDUs; absolute beginners should pair with a colleague who has rack experience.
Pricing basis
Per person for open sessions; private group rates for a single farm taking all seats. See the rates page for current figures. Deposits hold a seat; the balance is due seven days before start.
