Any chance this guy made it out alive? any further details?

OUCH!
This makes me glad the other techs told me to stand away from open
electrical panels at least without wearing a solid cotton shirt...

Probably, although he probably wishes he hadn>t.
I>m happy that I never have to do hi power hi voltage engineering.

Where>s the evidence that he was actually electrocuted? All
I can see is a big flash and smoke; this suggests a big
short circuit burning stuff up. The panel hides most of the
details. It appears he is working on something, such as turning
a wrench or working some mechanism like a hydraulic pump but
that>s purely my conjecture.
I>m guessing he had a lot of flash/flame burns at the least.
People have survived worse. Electrical burns can run deep and
are really hard to recover from.

He>s "racking" a circuit breaker (CB) - connecting it to a live HV bus
using a screw like mechanism. The CB was likely initially pulled for
periodic maintenance work. Although racking is done with the circuit
breaker open, there are a number of potential (abnormal) situations that
can make this activity very high risk.
The good news is that the electrician appears to be wearing protective
gear. He>s also standing off to the side, and the blast may have
actually blown him clear of the main stream of vaporized copper. If he
was full wearing protective clothing, face mask (or at least protective
goggles), and hearing protection, then the odds are good that he
survived this horrific incident. BTW, this particular arc flash event
was relatively LONG - about 5 seconds, and it may have been a higher
voltage feeder (greater than 480 volts). The arc quickly eats through
the top plate (likely ~1/4" steel) at the rear of the cabinet. These
events can easily evaporate the involved bus bars, like an
uncontrollable multi-megawatt welder from Hell...
