Wikipedia
Chemical accident
A chemical accident is the unintentional release of one or more chemical hazard substances which could harm human health and the environment. Such events include fires, explosions, leakages or release of toxic or hazardous materials that can cause people illness, injury, or disability. Chemical accident can be caused by natural disaster, or accidental human error, or deliberate move to cause chaos and destructions for personal gain.
While chemical accidents may occur whenever toxic materials are stored, transported or used, the most severe are industrial accidents, involving major chemical manufacturing and storage facilities.
