As the whole world was transfixed on the raging Palisades Fire, Dr. Ashraf Elsayegh was right there watching his home go up in flames.
"We wake up sometimes in disbelief like this didn't happen. We're gonna go back to our home," he said.

"Whether a physician is affected or not we have to do something to try to help our community," Elsayegh said.
He's no stranger to large-scale disasters. During the 9/11 attacks, Elsayegh was a resident in New York City and witnessed the initial horror and the recovery efforts.
"About 20 to 25 percent of all the people exposed to the World Trade Center are still requiring medical care for their lungs," he said.
He said L.A. residents will be exposed to the same toxic chemicals.
"They come from the burning cars that were parked in the homes, the burning furniture, the burning cleaning products. A lot of these are carcinogens and that's the problem," said Elsayegh

While he'd rather people wait to return, he knows how it feels to lose everything, but what's most important is to keep what you have, which is your health.
"Our clinic is going to start immediately and run for as many years as needed."
The toxic chemicals of concern are benzene, asbestos, lead and many others. These are toxins that can't be seen or detected. It's mixed in with the ash as well. He reminds us to wear an N95 mask when outdoors especially if you're in a sensitive group.
