Fires have finally stopped burning at the massive explosion site of the West Fertilizer Co., according to local officials at a press conference yesterday. Last Wednesday’s blast, which registered on the magnitude of a 2.1-level earthquake, took the lives of at least 14 and injured 200 others.
Fire officials have now determined the origin of the blast – an unmistakably enormous crater – but are remaining tight-lipped on even the broadest details like which building it came from. OSHA, the EPA, and the ATF are all looking into violations of each agency’s regulations (no criminal intent is suspected). But for a comprehensive, overall analysis, all eyes are on the 14-member team of the United States Chemical Safety Board (CSB).
Sandy Gilmour, CSB spokesman, said his agency’s investigators arrived on Thursday. But due to the ongoing fires and local fire marshal investigations, they have only just begun to sift through the rubble.
The CSB, a non-regulatory government agency, isn’t so much concerned with violations of specific rules or regulations. Similar to the National Transportation Safety Board, they look for any and all faults – often outdated or inadequate regulations. The CSB typically recommends new regulations or agency procedure changes.
For instance, in last year’s Chevron refinery fire in Richmond, Cali., corroded pipes were found to be at the root of the blaze. The CSB determined that checking pipes for corrosion was not part of Cal-OSHA‘s regular plant inspection process. “That seemed like a pretty obvious way to keep it from happening again,” Gilmour said.
The CSB can even suggest zoning modifications. Many homes in West were destroyed or damaged by Wednesday’s explosion, leaving some to wonder why explosive chemicals would be processed so close to town.
In its investigation of a 2006 ink factory explosion in Danvers, Mass., the CSB found “far too many residences” abutted the plant. When this plant was built in the 1940s, it was on a semi-isolated parcel of land. Then housing developments started creeping up on the factory, while it began using more volatile chemicals. Gilmour said zoning often needs to be reworked over time.
The agency’s full report on the West explosion could take up to a year to compile, but Gilmour estimates preliminary findings within three or four days.
