Israel's constructs underground hospital to prepare for CBRN attacks

In order to prepare for a possible chemical, biological or nuclear attack from Iran, Israel has constructed a four-story hospital almost entirely underground.

The hospital, located in Tel Aviv, can be fully self-sustained for a period of seven days. Dr. Gabriel Barbash said that it is more than a remote possibility that the hospital will be needed one day, according to PBS.

"I have no doubt in my mind that we'll have to use this facility," Barbash said, PBS reports.

Israelis are contemplating a strike against Iran's alleged nuclear weapons facilities and many are certain that if one occurs, there will be an immediate response.

"Iran will retaliate," General Amos Yadlin said, PBS reports. "No doubt about it. They've (been) preparing for it for the last five, six, seven years."

The underground hospital is currently serving as a parking garage for a full-sized hospital built above ground. It is capable, however, of becoming fully functional within 24 hours. Hundreds of beds can be wheeled into place in color-coded wards. The colors now help drivers remember where they are parked.

The hospital's entrance includes a rinse room for victims of a biological or chemical attack. The facility also has its own ventilation system to ensure the facility remains free of contamination, PBS reports.

The facility, called the Sammy Ofer Underground Emergency Hospital, was finished in 2010 at a cost of nearly $45 million. There is one other underground hospital in Israel and a third is under construction.
