Disasters

Hydrofluoric acid is a deadly chemical used in many petroleum refinery operations. When it escapes, it becomes a gas that can race long distances and kill people who inhale it. Safer alternatives are available to refineries. At the urging of petrochemical companies, Congress and the executive branch have kept the dangers largely secret from the at-risk public, so there has been little pressure for refineries to make their operations safer. In a joint investigation the Center for Public Integrity and ABC News found that worst-case scenarios filed by just 50 refineries showed some 16 million Americans at risk from accidental or intentional hydrofluoric acid releases.

"Lake Isabella Dam is just one acute example of a widespread problem: Of the nation’s 85,000 dams, more than 4,400 are considered susceptible to failure, according to the Association of State Dam Safety Officials. But repairing all those dams would cost billions of dollars, and it is far from clear who would provide all the money in a recessionary era."
