A Short Note From Storage Tank Explosion
What was happened last July 29 at Packaging Corporation of America, a paper mill company in Tomahawk, Wisconsin, should be received serious attention from us. An 80-foot-tall storage tank containing recycled water and paper fiber exploded when workers were welding on the top of it. Three persons was died and another one injured.
The U.S Chemical Safety Board (CSB) is now investigating the explosion and its chairman said it might be caused by microbiological activity. Please pay attention to The Chemical Safety Board preliminary analysis. “Large storage tanks at paper mills, especially those that are stagnant, poorly mixed or have material in them for a long time, are at an elevated risk for the growth of the organisms, producing hydrogen or other flammable gases that can be set off by hot work or other source of ignition.”
After reading this news, I think it had better for us to re-perform careful identification at our own chemical plant facilities that are potential introducing flammable gases that previously are not treated as the hazard source. Identify first!
