Darcy Street has been closed after a chemical leak in the Sydney Water headquarters basement caused the evacuation of about 1000 people about 1.30pm this afternoon.
It is currently 67 degrees inside the evacuated Sydney Water building in Parramatta, a Fire and Rescue NSW spokeswoman said.
She said Fire and Rescue attended the building on the corner of Smith and Darcy streets after an automatic fire alarm was set off about 12.53pm.
‘‘Some chemicals have been mixed in the basement of the building; it gave off a vapour,’’ she said.
She said police closed Smith Street and firefighters evacuated the building as a precuation.
‘‘Our hazardous materials [HazMat] firefighters are on the scene at the moment venting the building and making the area safe,’’ she said.
‘‘They’re also taking temperatures.
‘‘It’s 67 degrees inside the building.
‘‘It looks like we’ll be on the scene for quite some time monitoring that.’’
Three fire crews from Parramatta, Merrylands, and a HazMat crew from Chester Hill, are on the scene.
