LGT TAXIING OUT OF GATE CREATES JET BLAST DAMAGE AND INJURY.

Narrative

GATE A AT MSP IS LOCATED IN A HIGHLY CONGESTED AREA. PUSHBACK WAS SHALLOW AND NOT AS DEEP AS IT COULD HAVE BEEN BUT; AT THE MOMENT; DID NOT CAUSE CONCERN. RECEIVED TAXI CLRNC TO RWY 29R WHICH MEANT A L 90-110 DEG TURNOUT. WHILE IN TURN; WAS ADVISED TO USE TXWY D TO OUTER TXWY. THIS CAUSED A TIGHT 270-290 DEG L TURN (R TURN IMPOSSIBLE; AT THIS TIME) AND NECESSITATED JET BLAST TO BE DIRECTED TOWARDS ACFT; MEN; AND EQUIP STILL IN THE GATE AREA. THIS WAS A VERY TIGHT TURN BUT WAS NOW COMMITTED TO MAKING THE TURN (COMBINATION OF PWR AND BRAKING WAS NECESSARY). I SHOULD NOT HAVE MADE OR ACCEPTED THE CLRNC TO TXWY D. AT NO TIME WAS EXCESSIVE PWR APPLIED. (1.2 EPR ON #1 AND #2 ENG. #3 WAS NOT STARTED.) USE OF 'TXWY D TO OUTER TO RWY 29R' WAS USED TO ALLOW OTHER ACFT PUSHBACK CLRNC AT GATE B. I SHOULD HAVE SAT BACK AND REQUESTED TO RWY 29R VIA THE INNER. IT WAS RPTED TO ME UPON ARR IN MSY THAT; INDEED; LIGHT EQUIP (LADDERS; ETC) WERE BLOWN AROUND AND THAT A MECH HAD HURT HIMSELF (VERY MINOR FINGER CUT) TRYING TO ESCAPE THE JET BLAST.
