US Superdome bomb shelter

The US super-durable bombardment chamber was capable of withstanding pressure and contained any debris after the bomb had exploded.

On the night of September 16, after a bomb exploded in Chelsea's Chelsea district, 29 police were injured. New York police used robots to check and place another bomb inside the super-durable chamber to deliver them. safe.

According to Live Science, this device, called TVC , is capable of withstanding pressure and containing any debris after the bombs in it explode. TVC can carry the bomb and move it to another location without evacuating or prohibiting the road, said Grant Haber, vice president of American Innovations. This is a company that supplies explosive detectors and containers and evacuation plans.

If the bomb detonated during the move, TVC could "keep the original fragments and the bomb would not endanger anyone in the vicinity," Haber said.

Most TVCs fall into one of two categories: sealed or ventilated . In seals, apart from debris, any chemical or toxic gases are trapped inside, said Keren Banai, North American sales manager for Mistral Security, a TVC provider. .

If it is aeration, the gases after the explosion will be pushed out in a controlled manner, Bannai said. Depending on the amount and type of explosives, as well as the aperture of the valve, the sound of the gas when released will vary, from a startling explosion or just as whistling, Haber said.

If the authorities are concerned about the gas produced after the explosion, they can lead it into two containers, one for trapping explosive gas and one for air purifiers.

In addition, TVC also has the function of safe explosives storage.

"There are chambers that are used to store explosives with a potentially explosive atmosphere , such as the Mistral, which can contain explosives of 30 grams to 45 kilograms, " Bannai said.

TVC bombers have a mass of 5 to 9kg, while TVCs are used to store bombs of up to 45kg. Their prices are quite expensive, from $ 150,000 to $ 500,000.
