Two workers chinese, who were painting part of the asphalt near a culvert, miraculously saved their lives when a loud bang lifted them into the air with a large part of the street.
The explosion occurred in recent days in the city of Wuhan, China, and the incident was recorded on security cameras.
In the video, you can see how the workers are in the middle of the street performing their tasks when the explosion occurs inside the sewer. Immediately, all the people circulating around the site began to run.
In the images you can also see a motorcyclist flying through the air about two meters due to the terrible blast. And a white truck, which was parked on the curb of the sidewalk, rises as a result of the strong explosion.
As a result of the incident, four people were injured but none seriously. The experts studied the reasons for such an explosion and came up with an explanation: methane.
The strange event is due to the fact that the workers were applying a type of asphalt that came into contact with the methane accumulated in the subsoil inside the culvert. The union of these two elements generated a chemical reaction that released an enormous amount of energy.
