One person is in a serious condition after highly toxic hydrogen sulphide gas leaked from a truck-and-trailer unit at a Taieri industrial park.
Silverstream Industrial Park in Dukes Rd was cordoned off by police, and firefighters were also at the scene after the alert was raised about 12.10pm yesterday.
One person transported by ambulance to hospital was initially listed as critical.
Their condition had since been downgraded to serious, a Hato Hone St John spokesman said.
Two other patients were assessed at the scene.

A Fenz spokeswoman said the leak had been isolated by about 1.15pm and they left the scene about 2pm.
Workers were evacuated from the park for a time.
