"Most likely human error. The consequence has the say. They will do a variety of examinations. In a similar case of explosions of pyrotechnic products, it is about human error and static electricity, said in "The day begins with Georgi Lyubenov". Valentin Radev - explosion expert and former interior minister.
He pointed out that around the world, when such incidents occur, static electricity is almost always involved. He expressed doubt that there were still violations during the construction of the warehouse and the requirements were not met.
"They don't have the right shoes, static electricity, it explodes and so on".
Valentin Radev described what happened on the fateful afternoon.
"This is one warehouse that has several storage facilities. A total of 6. One entrance is from the Elin Pelin station. They go there after 17:00 the docent, his daughter and the owner's son Todor. They are going to prepare something that will be on Saturday or Sunday. They park the van inside and enter a room that didn't even have four walls.
It is there that the explosion occurs and the shock wave throws the daughter out.
"The bad news is that this explosion is being transmitted to the other repositories. One by one".
In his words, the warehouse was not built according to the rules of the military regulations. There is also a gas pipeline that only the owner knew about.
"The warehouse that blew up was with pyrotechnics. These are not explosives. There are no shells. And the biggest danger is fires", emphasizes Valentin Radev.
He added that the pressure that rises and in it there are particles, fireworks. I.e. the cloud rises, they ignite and set the roof on fire. Radev was adamant that there is no 24-hour period that must elapse in order to inspect the scene of the accident.
"There is no such rule. It is entered at the earliest opportunity. What they can save".
