Lemoore Water Tank Explosion In a recent analysis, Philip Myers PE of PEMY Consulting dives deep into the Lemoore, California water tank explosion that tragically occurred in June 2021. This incident, which resulted in one fatality and one injury, underscores the critical importance of safety protocols in hot work situations.

Incident Overview​

During a routine welding operation on a water tank holding approximately 1.5 million gallons of water, a catastrophic explosion occurred. Surveillance footage captured the dramatic moment the tank was propelled approximately 70 feet into the air due to an overpressure event, causing significant damage to the surrounding infrastructure.

Key Insights from the Analysis​

Myers emphasizes that incidents like this can often be prevented through rigorous adherence to safety standards and procedures, particularly concerning hot work. Here are some crucial takeaways from his discussion:

1. Understanding Vapor Space Explosions:
   • The explosion was likely caused by a vapor space deflagration, where flammable gas accumulates in the tank above the water level.
   • The rapid combustion of these gases resulted in an overpressure situation, leading to the dramatic failure of the tank structure.
2. The Importance of Atmospheric Testing:
   • Before commencing any hot work, surrounding areas must undergo thorough atmospheric testing to ensure safety.
   • Hazardous vapors can be odorless and undetectable without the appropriate testing equipment, making this step imperative.
3. Safety Recommendations:
   • Myers suggests utilizing frangible roofs on tanks to mitigate risk during overpressure events—this design feature allows the roof to blow off safely, preventing catastrophic spills and further explosions.
4. Call to Action:
   • The video ends with a crucial message: Never assume confined spaces are free from hazardous conditions. Always engage qualified personnel for safety inspections before proceeding with potentially dangerous work.
     

     Conclusion​

     If there's one lesson from the Lemoore water tank explosion, it’s the paramount importance of safety protocols in environments involving hazardous materials and hot work. Myers’ insights serve not only as a reminder but also as a guide for professionals in engineering and construction sectors.
