(CNN) — Half of the firefighters on duty in San Francisco on Tuesday night were battling a blaze at a construction site that is threatening nearby buildings, authorities said.
Officials evacuated “several hundred” residents across the street from the blaze, said Mindy Talmadge of the San Francisco Fire Department.
“The buildings across the street that are inhabited were evacuated,” Talmadge said. “The heat from the fire was making the windows pop and firefighters had to put up a water curtain to prospect the buildings.”
At least 150 firefighters are involved.
The construction site and the scaffolding around it have collapse into the site, she said.
San Francisco Fire Chief Joanne Hayes White said the entire structure will likely collapse due to a combination of damage and water used on the blaze.
