A local man is suing Union Carbide Corp. [part of Dow] and numerous petrochemical companies alleging his relative died from prolonged asbestos exposure… Willie E. Woods died two years ago from lung cancer… BP, Amoco, Dow, Chevron, Shell, and Texaco [part of Chevron] join Union Carbide as defendants. "Each defendant bears responsibility in causing Willie Woods' injuries in the individual capacities in which they have been sued," the original petition says.
