Unanticipated Blast: A Gas Tank inferno with a scorching five-meter flame jet
After the gas tank blast in Göppingen, spewing a five-meter tall flame jet, the local law enforcement has shed some light on the event's potential cause - a mechanical flaw. In an official statement on Thursday, a police spokesperson pointed to a worker from a specialized company attempting to empty the liquefied gas tank to perform repairs. A malfunction occurred, releasing a nozzle and stopcock on the cap, leading to a spark and an ensuing inferno. The gas ignited, resulting in a towering flame jet.
To contain the fire from spreading to the neighboring business, the tank and its surroundings were drenched with water. The fire department permitted the 2,500 liters of gas within the tank to burn off gradually in a controlled manner. Initial damage estimates put the tank's repair bill at around 20,000 euros. The authorities ruled out any involvement by third parties in the incident that occurred on Wednesday. fortunately, no injuries were reported.
The mechanical flaw behind this gas tank blast poses an increased risk for similar incidents, emphasizing the importance of frequent inspections and upkeep for such tanks to avert future Fires and potential mishaps.

Preventive measures like regular inspections, maintenance, and monitoring can significantly lower the risk of mechanical defects causing gas tank blasts and incidents. Here are the primary strategies to implement:
- Visible Inspections & Non-Destructive Testing:
- Daily or monthly visual checks may flag apparent problems like leaks, rust, or gauge anomalies, averting potential gas tank explosions.
- Utilizing non-destructive testing techniques, such as ultrasonic or radiographic analysis, allows for a more comprehensive assessment of vessel components like seals, welds, and connections, identifying weaknesses before they pose a threat.
- Preventive Maintenance:
- Routine activities like lubrication, adjustments, and replacement keep equipment in top working shape, diminishing the probability of mechanical failures.
- Lockout/Tagout procedures secure energy sources during maintenance activities, preventing the release of hazardous energy and potential accidents.
- Monitoring & Control Systems:
- SCADA systems monitor pipeline conditions in real-time, enabling proactive safety management and early identification of abnormalities, like leaks or excess pressure.
- Integrating fire and gas detection sensors, such as infrared and ultrasonic detectors, can identify leaks and unusual heat patterns, prompting immediate action to avoid explosions.
- Pressure Relief Systems:
- Rupture disks and safety valves maintain internal pressure control, avert critical breakdowns, and minimize the likelihood of explosions.
- Regular inspections and testing, at least annually, assure that relief valves function properly during overpressure scenarios, thereby averting potential explosions.
- Comprehensive Maintenance Programs:
- Thorough inspections and tests monitor equipment status and prompt identification of potential issues, while documentation and record-keeping ensure traceability on equipment condition.
Implementing these countermeasures reduces the risk of mechanical defects leading to gas tank explosions and incidents, making workplaces safer and lowering potential hazards.
