Acting Englewood Fire Chief Gerald Marion says a pipe became loose at the top of the La Esperanza Bakery silo as flour was being pumped into the building on Tuesday.
Some people thought there was an explosion as flour filled the air and coated several adjacent buildings.
A spokesman for the bakery told The Record newspaper it lost probably less than 10 bags of flour from the 20,000 pounds that were being delivered.
The pipe has been resealed.
