CNG Vehicle Tank Burst During Filling 2008-01-0557
A CNG (Compressed Natural Gas) airport shuttle bus was being refueled in Carson, California when an onboard CNG tank burst. This caused fatal injuries to the driver. The accident occurred on Saturday, May 26, 2007.
This incident may provide useful lessons learned for future CNG and compressed hydrogen vehicles in the area of corrosion resistance; verification of tank life; and tank installation, protection, and inspection methods.
Tanks should be inspected after a vehicle crash or fire, and tanks should be removed from service or recertified at the end of their intended life.
