## Narrative

Silicate Plant Tray Dryer (Zone #3) had unburned fuel that ignited, creating a small explosion. This created enough pressure to open most of the dryer doors. Discovered that the air flow switch had been jumpered out, allowing the gas to remain on with not enough air to burn all the fuel. No injuries were sustained and one section of the roof on the west side buckled (minor damage).
