Location
MS, ATTALLA
Narrative
During a change of weather from very warm weather to very cold weather, metal particles in the line were entrained in the gas stream. The metal particles cut and damaged the rubber diaphragm controlling pressure and settled in the pressure reilef pilot. Rising pressure caused the service regulator at a grocery store to fail, which then caused excessive pilot light flames at the appliances inside the store. These flames caused a fire, which damaged the building and contents. The store was closed at that time. There were no evacuations. There were no injuries or deaths.
