"NTSB Investigates Deadly Explosions at Pa. Chocolate and Candy Factories"

The National Transportation Safety Board has opened a safety investigation into a natural gas explosion and fire at the R.M. Palmer Company factory in West Reading, Berks County, which killed seven workers. Initial findings indicate an accident involving a natural gas pipeline caused the explosion. The blast highlights the combustibility of food plants, particularly chocolate making, and the risks of combustible dust produced by ingredients like cocoa powder and corn starch. The community is offering support to the families of the victims, and a candlelight vigil is scheduled for Friday.
