The problem here is OSHA's lack of teeth. Clearly some companies do not place a high enough value on the safety of their employees and the environment.
Regarding worker's saftey... Tyler Pipe, which is owned by McWade, has the unenviable reputation of being a terrible place to work. The number quoted, 4600 injuries in 5 years is correct. Among these are many violent fatalities - people getting sucked into unguarded (illegal) moving conveyor belts, and machinery being turned on with employees inside, amongst others. According to the report following an OSHA nspection, burns and amputations ar commonplace, and the employees have scars visible from many feet away. Conditions are so bad that the company has fallen to recruiting ex-convicts. Turnover is incredibly high. Contrast this with at least one similar foundary (I forget the name of the company), where there is a waiting list for prospective employees. I don't have numbers on injuries in that plant but you can draw your own conclusions.
Now, what of the environment? Another McWade company, located in New Jersey, was found to be releasing toxic wastewater into the Delaware River, on a day-to-day basis. McWade's various subsidiaries have been cited for hundreds of environmental violations within just a few short years.
Clearly the company is in violation, the question is, why can it not be motivated to turn itself around? Well, take for example the loss of a worker's life. Under OSHA's rules, the company is to be fined 7,000 dollars. This from a company with $2 billion in revenue. That is less than a slap on the wrist. In my opinion, this sort of repeated violation deserves a fine on the order of tens if not hundreds of millions as well as prison sentances for those who molded the company policy into what it is now.
This stuff just pisses me off, I got my info from a Frontline report (it was a combined NY Times Frontline effort), I strongly suggest you watch it if you can (its on PBS).
