DENVER -- The Denver Fire Department responded to a chlorine leak in the northeast part of the city Friday.

"There was a yellow haze plume coming from a building behind United Rentals," a witness said.
The building where the incident happened and those surrounding it were evacuated, DFD said.
40th Avenue was closed during the response and investigation. Roads were reopened late Friday afternoon.
Seven people were taken to hospitals according to a DFD spokesperson.
According to a UC Health representative, seven of the injured people were taken to the CU Anschutz Medical Campus.
High Tech Early College, which is located on the other side of I-70 from the scene of the chlorine leak, experienced a natural gas leak. The school was evacuated. One person was transported from that scen. The students and staff were eventually allowed back inside.
