- Description
Heavy rains (more than 600 mm in 1 day) had flood a factory manufacturing calcium core electrical conductors. The power supply was cut off. The water came into contact with the calcium stored in 150 kg containers, producing hydrogen (7.5 kg per container). The heat of reaction ignited the gas. The fire was extinguished with sand.
