California officials said that at least 19 people were injured Friday in Oakland after a building where they were working on partially collapsed.
It happened as workers were pouring wet concrete of the second floor of the building, KTVU reported. The workers were briefly trapped in the wet concrete and some were left dangling from the scaffolding.
Emergency responders transported the injured from the website of Alta Bates Summit Medical Center and two other hospitals, a spokesman of the hospital said.

No deaths or serious injuries reported, Oakland Fire Battalion Chief Ian McWhorter said. The workers suffer from slight injuries such as scrapes and bruises.
The cause of the collapse is being investigated.
“We don’t know exactly what the cause of this incident to prevent it,” McWhorter said.
