The man, who wants to remain anonymous, says he was in the Alviso area with his wife when he saw the fireworks.
"We saw that they were working on pretty big things, right. So, we started to go on the side to pass it and just walk away, right. And then, in one second, that was it. We were on the floor, burned. I just look at my wife. Her skin was falling from her legs."
The victim says when they asked to call 911, people told them, "We don't do that around here."
