MS, HINDS
Narrative
We received a report of a fire at a residence located at 409 w. Hill dr. In jackson, ms. The responding service technician arrived on scene in 15 minutes. The operations supervisor was subsequently notified. Some of the exterior walls had been displaced outward indicating a possible explosion. We notified the national response center and the director of pipeline safety (mpsc). Due to heavy rains saturating the soil, performance of leak surveys around the premise were difficult. Ultimately a leak was found behind the left rear corner of the house alongside the side street (magnolia dr.). The saturated soil caused gas to migrate along the roots of a tree towards the residence. In haste to secure the scene and stop the leak, the construction crew shut off the service tap and dislodged a mechanical fitting connected to the tap. As a result, it is impossible to know for certain the specific source of the leak.
