Not likely. OSHA was not the source used for the data. Rather, data from workers' comp, fatalities, etc. - all data a bit harder to fudge - was the basis.
Confirming this point, there have been several case studies where changes in management / culture were matched to changes in accident rates - going in both directions.
In a nutshell, it is the awake, aware, alive worker, who feels 'in control' and is supported by the corporate culture who is safe. If he feels he's just a cog in the machine, with management that believes employees should be seen but not heard - thats' where accidents happen.
