(KRON) — An explosion at a chemical plant in northern Spain has covered the city in a toxic orange cloud.
The explosion happened around 9 a.m. at Simar, a chemical distribution company located in Igualada, Catalonia.
Officials say a delivery package containing chemicals such as nitric oxide and ferric chloride became mixed and exploded as a result.
Nearby residents were ordered to shelter in place.
According to officials two people were slightly injured, and three firefighters needed treatment for minor ailments.
About two hours after the explosion, emergency services lifted the advisory but said children, pregnant women, elderly people and anyone with respiratory illnesses should remain in their homes.
Very little wind in the area is preventing the cloud from dissipating more rapidly.
