A safety valve on a natural gas tank failed Monday and caused a loud boom and a gas cloud to be released at the Cummins Tech Center, 1900 McKinley Ave., a Columbus firefighter said.
Around 1:20 p.m., a noise that sounded like an explosion prompted calls for the fire department to respond, said Capt. Doug Hollenbeck.
Cummins compresses natural gas to use in test trucks, Hollenbeck said, and a relief valve failed, causing the noise and gas to be released.
There were no injuries in the incident, Hollenbeck said. Firefighters stayed while Cummins gas systems were shut down and then restarted, to make sure there were no additional problems, Hollenbeck added.
Fire Stations 1 and 3 and Squad 2 responded and were on the scene for about 30 minutes.
