Workers repairing the Qarmat Ali water injection plant in Iraq were told that the orange substance strewn around the facility was only a mild irritant – but after two-and-a-half months of exposure to it, many workers felt ill. Farah Stockman reports in the Boston Globe:

But the chemical turned out to be sodium dichromate, a substance so dangerous that even limited exposure greatly increases the risk of cancer. Soon, many of the 22 Americans and 100-plus Iraqis began to complain of nosebleeds, ulcers, and shortness of breath. Within weeks, nearly 60 percent exhibited symptoms of exposure, according to the minutes of a meeting of project managers from KBR, the Houston-based construction company in charge of the repairs.

Now, nine Americans are accusing KBR, then a subsidiary of the oil conglomerate Halliburton, of knowingly exposing them to the deadly substance and failing to provide them with the protective equipment needed to keep them safe.

KBR claims it should be protected from employee lawsuits under the Defense Base Act. Since KBR hired the workers through two subsidiaries, though – a move that let them avoid hundreds of millions of dollars in payroll taxes – they may not qualify as an employer, and may be ineligible for that protection.
