A chemical accident is the unintentional release of one or more hazardous substances which could harm human health or the environment. Chemical hazards are systems where chemical accidents could occur under certain circumstances. Such events include fires, explosions, leakages or release oftoxic or hazardous materials that can cause people illness, injury, or disability.
While chemical accidents may occur whenever toxic materials are stored,transported or used, the most severe accidents are industrial accidents, involving major chemical manufacturingand storage facilities. The most significant chemical accident in recorded history was the 1984 Bhopal disaster in India, in which more than 3,000 people had died after a highly toxicvapour, (methyl isocyanate), was released at a Union Carbide Pesticidesfactory.
Efforts to prevent accidents range from improved safety systems to fundamental changes in chemical use and manufacture, referred to as primary prevention or inherent safety.
In the United States, concern about chemical accidents after the Bhopal disaster led to the passage of the 1986Emergency Planning and Community Right-to-Know Act. The EPCRA requires local emergency planning efforts throughout the country, including emergency notifications. The law also requires companies to make publicly available information about their storage of toxic chemicals. Based on such information, citizens can identify the vulnerable zones in which severe toxic releases could cause harm or death.
