McClatchy Newspapers WASHINGTON — Plans to burn hundreds of thousands of gallons of oil from BP's blown-out well are raising new questions about the health and safety of the thousands of workers on rigs and vessels near the spill site.
BP and the federal government are in new territory once again in dealing with the nation's worst environmental disaster: There's never been such a huge flaring of oil in the Gulf of Mexico, or possibly anywhere.

Dr. Phil Harber, a professor at the University of California, Los Angeles, said the burning oil could expose workers to toxins that might cause severe respiratory irritation, asthma attacks and inflamed airways depending on how the burns are handled. Burning oil is a fairly common method of relieving pressure in refinery operations, he said.
"But the magnitude is a concern," said Harber, who's also the chief of UCLA's division of occupational and environmental medicine.
The other worry, he said, is if the wind carries off the thick clouds, "there are hundreds of ships in the area, and those workers could have significant exposures and perhaps less protection because the exposures would be unanticipated," he said.
Harmful byproducts of burning the light crude flowing into the Gulf include fine particles; toxic gases such as sulfur dioxide, nitrogen oxides and carbon monoxide; polycyclic aromatic hydrocarbons, or PAHs, which result from the incomplete burning of carbon-containing materials such as oil; and volatile organic compounds such as benzene toluene, ethylbenzene, and xyle

I did notice how Schlumberger wasn't defending how cleanly their Evergreen burner burned in the article, only that "excess oil and gas had been being burned off around the world for the past 40 years."
I guess they need to pick days when the wind is blowing toward Houston. The pollutants will get lost in the vast cloud of toxins that now passes for Texas' air, and no one will even notice.
