If that is really the case, the employers involved in my opinion are guilty of serious negligence, if not worse. And in all cases, workers or their relatives should be fairly compensated for suffering and death. But at this moment we are almost 25 years later and the story is rather different.
Most victims are from before the nineties.
There are no victims under the workers from after measures to reduce VCM levels at the work place. No matter if that is better for the environment or not. All means and stories are good to reach that target, including this one. Crude oil contains hundreds of carcinogens, including benzene, waxes and PAH's. Sand for glass and concrete is a carcinogen.
