Narrative
Per national transportation safety board ("ntsb") investigation id pld25fr006, the following information is preliminary and subject to change. On june 12, 2025, a natural gas-fueled explosion and fire destroyed a single-family residence at 14109 kenneth court in crestwood, illinois. The explosion killed one person and damaged neighboring residences. Nicor gas provided natural gas service to the home and the neighboring residences. The crestwood fire department responded to the explosion and fire at about 2:16 p.M. Nicor gas arrived on the scene at about 2:40 p.M. And disconnected and capped the service line at about 4:44 p.M. On june 13, 2025, nicor gas performed a pressure test of the service line. The service line did not hold pressure, indicating a leak. After national transportation safety board (ntsb) investigators arrived on scene, nicor gas performed flow tests on the service line to estimate the size of the leak. Barhole testing conducted by nicor gas confirmed the presence of gas in the ground near the foundation of the home. Nicor gas located and marked underground utilities at the accident site and obtained gas consumption data from the home�s gas meter. While on scene, ntsb investigators completed the following actions: � examined the accident site, � secured a section of the service line containing the leak for examination at the ntsb�s materials laboratory in washington, dc, � reviewed the accident home�s gas consumption data over the past year, which was higher than the neighboring residences, � requested documentation from nicor gas, � requested communication logs from nicor gas and the crestwood fire department, � and conducted interviews.
