A BLEVE (boiling liquid expanding vapor explosion) can occur when a vessel containing a pressurized liquid is exposed to a heat source. The liquid inside the container boils, causing the pressure to increase. If the pressure inside the vessel becomes too high, it can rupture, releasing the pressurized liquid. The liquid then vaporizes, causing an explosion.
BLEVEs can be extremely dangerous, as they can cause extensive damage to property and injuries or even death to people nearby. It is essential to be aware of the potential for a BLEVE and take precautions to prevent it from occurring.
How to Prevent it From Happening
BLEVEs are hazardous and can cause severe property damage and even loss of life. That’s why it’s essential to be aware of the potential for a BLEVE and take steps to prevent it from happening in your home.
There are a few things you can do to help prevent a BLEVE:
- Keep flammable liquids in closed containers: This will help to prevent the liquid from being exposed to a sudden change in temperature.
- Store flammable liquids away from heat sources: This will help to prevent the liquid from being exposed to a fire.
- Inspect containers regularly: This will help to identify any potential damage to the container that could lead to a BLEVE.
- Be prepared to shut off the gas: If you smell gas or see a fire, shut off the gas immediately. That will help to prevent the fire from igniting the flammable liquid.
- Know where the emergency shut-off valves are located: In the event of a fire, you’ll need to be able to shut off the gas quickly. Knowing where the emergency shut-off valves are located will help you do this.
BLEVEs are rare, but they can be devastating. Taking some simple precautions can help prevent a BLEVE from happening in your home.
How to Know if There Is an Upcoming BLEVE
A few signs may indicate that a BLEVE is about to occur. Make sure to watch out for these:
- The liquid in the container is boiling, and the vapor is not escaping
- The container is under pressure from the vapor
- The container is starting to bulge or rupture
If you see any of these signs, immediately moving away from the container is essential, as it could explode anytime.
What to Do After a BLEVE
BLEVEs are relatively rare, but they can be devastating when they do occur. Here are some things to keep in mind if you find yourself in the aftermath of a BLEVE:
- Seek medical attention immediately if you are injured.
- Evacuate the area if possible. If you can’t evacuate, find a safe place to shelter.
- Be aware of your surroundings. BLEVEs can cause secondary explosions and fires, so it’s essential to be mindful of your surroundings and be prepared to evacuate if necessary.
- Avoid using electrical appliances or equipment. There may be damaged wiring or other hazards present.
- Do not smoke.
- If you smell gas, leave the area immediately and do not return until the utility company has determined it is safe to do so.
- Contact your insurance company as soon as possible.
- Also, contact the cooperative extension service or your local fire department for information on cleanup and safety precautions.
Boiling liquid expanding vapor explosions are one of the most dangerous types of explosions that can occur in industrial settings. It is crucial for those who work with or around hazardous chemicals to be aware of the potential for a BLEVE and to take steps to prevent it from occurring. It is also best to be aware of the signs of a potential BLEVE so that you can take steps to protect yourself and others in the area.
