The Texas plant that was the scene of a deadly explosion this week was last inspected by the Occupational Safety and Health Administration in 1985. The risk plan it filed with regulators listed no flammable chemicals. And it was cleared to hold many times the ammonium nitrate that was used in the Oklahoma City bombing.
For worker- and chemical-safety advocates who have been pushing the U.S. government to crack down on facilities that make or store large quantities of hazardous chemicals, the blast in West, Texas, was a grim reminder of the risks these plants pose. And they say regulators haven’t done enough to tackle the problem.
