The West Fertilizer Company facility that exploded in a deadly blast last week had not been inspected by OSHA in at least 10 years, according to advocacy group Public Citizen, which says too many similar facilities operate “with very little oversight” from regulatory agencies.

An explosion at a fertilizer plant in Texas last night powerful enough to cause a magnitude 2.1 earthquake has killed up to 15 people – and possibly more. Waco, Texas police Sgt. William Patrick Swanton said he expects the casualty rate to rise. A number of firefighters are among those still missing after the blast. (Firefighters – including volunteers – were at the plant fighting the blaze when the explosion occurred.)
