I do hope they have more training than that in store for you.
Mines have their own rules, and are exempt from the NEC - IF they're mines. A buried laboratory would, generally, need to meet NEC. For those who are wondering, following the NEC can actually create hazards in some mining situations... hence the special rules.
Voltages over 600 have their own rules. They better see to it you learn them - and have the appropriate tools and equipment available! This will be especially important, as high voltages tend to make air less resistant to electrical current flow - and, if the air is not replaced immediately with fresh air, you'll be exposed to some pretty amazing arcs.
