How many people died while building the Empire State Building?
Though rumors of hundreds of people dying on the work site circulated during the time of its construction, official records state that only five workers were killed: one worker was struck by a truck; a second fell down an elevator shaft; a third was hit by a hoist; a fourth was in a blast area; and a fifth fell off a scaffold.

It's impossible to calculate an OSHA DART rate based on this info since the most severe form of injury is referenced here -- death -- and that there were five during the construction.
But we can come close.
0.143 is the DART rate associated with only Deaths. Something tells me that OSHA wouldn't be entirely thrilled with that statistic today. Each death is investigated by OSHA.
Formula:
N = number of deaths
200,000 = the number of average work hours in a year for a single worker (certainly not the case in this case, but it's the best we can do).
7,000,000 = the number of man hours worked to erect the ESB.
5*200,000 = 1,000,000/7,000,000 = 0.143 DART rate for only Deaths.
