Narrative
The san antonio police department report stated that there were three residents at home when an explosion occurred in between two bathrooms near the master bedroom. The residents were transported to the hospital for observation and one resident was admitted for further evaluation. Cps energy gas troubleman conducted an outside leak investigation and found gas reads under the slab, in the yard, inside two other homes, and in the yards of two additional properties. Cps energy crews found the primary cause of the gas migration to be a gas leak on a cracked polyethylene butt fuse near the service tap on the 1" gas service serving 9646 south bend (address of incident). A secondary gas leak was also found at the riser of a 1" gas service serving the home next door to the incident (9642 south bend). Cps energy leak surveyed the surrounding area including the 2k grid map that is on the leak survey cycle. Cps energy had external testing conducted and the conclusion was that the pipe material was fit for service supporting the primary cause as a fusion connection failure.
