Chemical Tank Emergency in California Ends Safely
Thousands of people can return home after firefighters prevent dangerous explosion at aerospace company.
The emergency started last Thursday at GKN Aerospace in Garden Grove. Workers called 911 when they noticed problems with a large chemical tank. The tank held a chemical called methyl methacrylate, which can be very dangerous if it gets too hot. Firefighters arrived quickly to help with the situation.
At first, officials worried the tank might explode. The worst type of explosion is called a BLEVE, which stands for Boiling Liquid Expanding Vapor Explosion. This kind of explosion can destroy buildings and hurt many people. Fire Chief TJ McGovern said this was the most dangerous possibility they faced.
Firefighters used a special water system to keep the tank cool. They sprayed millions of gallons of water on the tank every day. The water helped lower the temperature from 100 degrees to 92 degrees. This made the tank much safer and prevented an explosion.
Over the weekend, about 50,000 people had to leave their homes. By Tuesday, most people were allowed to return home safely. Only 16,000 people still needed to stay away from the area closest to the factory. Health officials told people it was safe to go back to their houses.
We found a plan and we implemented it.
