Toxic gas Thursday leaked from tanks in a cargo warehouse in the Brazilian coastal city of Guaruja sending some 40 people to hospitals.
The Guaruja fire department said rainwater seeped into the container where the tanks containing sodium chloride isocyanate were stored, causing a chemical reaction that sent a large white cloud into the sky.
Guaruja Mayor Maria de Antonieta de Brito asked people to stay home because the gas can cause skin irritation, burning sensations, fainting spells and breathing problems.
