Chelmsford chemical leak: Five taken to hospital
Five people have been taken to hospital after a number of containers leaked an unknown hazardous substance at a addiction treatment centre in Essex.
Firefighters were called to the centre in New London Road, Chelmsford, about 17:25 BST when staff began feeling unwell after inhaling the chemicals.
The building was evacuated and the chemicals were made safe.
The five people were "decontaminated" on site, the fire service said, and taken to hospital for a check-up.
Gary Sanderson, from the East of England Ambulance Service, said five people felt unwell and had problems breathing.
"Following treatment at the scene, all five patients will be conveyed to Broomfield Hospital for further care," he added.
