SAO PAULO – Officials say toxic gas has leaked from tanks in a cargo warehouse in the Brazilian coastal city of Guaruja. The company owners said the containers in Santos were full of acid and an antiseptic which came into contact with rainwater, causing a reaction. The area’s mayor said at least 66 people were taken to hospital with breathing difficulties. Officials said the fire had been controlled but that there is still smoke in the area. The cargo terminal and nearby homes were evacuated and residents were asked to stay inside. The container terminal was operated by Localfrio, a logistics company, in Guaruja, an area on the eastern side of Santos, in Sao Paulo state. Local Mayor Mario Antonieta de Brito asked people to stay out of the rain which could “contain chemical elements that can burn the skin”.
