Residential Natural Gas Explosion
and Fire

In the middle of the night, a multi-story residence in South San Francisco exploded and burned to the ground. APTECH was hired by the local gas utility to come to the site and conduct a root-cause investigation. An immediate site inspection was required because the local fire department authorities required that the smoldering debris be removed immediately. In this way, the fire could be completely extinguished and any threat to adjacent structures eliminated. APTECH was on site immediately and, working with other investigators, quickly determined that the gas pipeline into the building had been hack-sawed completely through at a location upstream of the regulator. Deliberate arson was the obvious cause and was eventually traced to the building's owner.
