Officials Warn Residents on Rising Danger of Cyanide Gas

(Tianjin) – Clean-up efforts at the site of the Tianjin blast have focused on the risk that sodium cyanide in the area could turn into a hazardous gas with rainfall.

As heavy rain fell briefly on the morning of August 18, white-colored foam streamed onto Huanghai Road in Tianjin's Binhai New Area, 5.5 kilometers away from the site of blasts.

A number of reporters exposed to the rain complained about a burning sensation in their lips and joints, though it is not clear if the foam is linked to chemical spills in the wake of the massive August 12 explosions.
