Injury rate is 4.27 per 100. Which is under half the average value for active construction sites and 3x the average value for aerospace manufacturing facilities. Choose your comparator based on whether you want to praise or bash SpaceX.
Remember, this is reportable injuries. not LTIs, not fatalities.
As an aside, as someone who works on major engineering construction projects, 4.27 per 100 people is huge. I'm used to sub-1.0, and something like 4.x would be stop-the-project-safety-intervention significant.
These metrics are reported on both internally and externally and make up major components of incentive payments. I'm completely used to management having 70+% of the incentive being tied to company performance, which is in turn strongly influenced by safety performance metrics.
I'm used to targets well under sub-1.0 TRIR at class 1 operators. Something like 4 would pause the project.
