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 releases

of toxic or hazardous materials that can cause people illness, injury, disability or death. An example is the

introduction of hydrocarbon methyl that increases the risk of heart cancer because it changes the way

blood cells flow through the body.[1]

While chemical accidents may occur whenever toxic materials are stored, transported or used, the most

severe accidents are industrial accidents, involving major chemical manufacturing and storage facilities.

The most significant chemical accident in recorded history was the 1984 Bhopal disaster in India, in which

more than 3,000 people were killed after a highly toxic vapour, (methyl isocyanate), was released at

a Union Carbide pesticides factory.

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

1986 Emergency 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.

In 1990, the Chemical Safety and Hazard Investigation Board was established by Congress, though the

CSB did not become operational until 1998. The Board's mission is to determine the root causes of

chemical accidents and issue safety recommendations to prevent future Safety Performance Indicators. It

also organizes workshops on a number of issues related to preparing for, preventing, and responding to

chemical accidents.[2]

In the European Union, incidents such as the Flixborough disaster and the Seveso disaster led to

legislation such as the Seveso Directive and Seveso planning and provide for safety reports to local

authorities. Many countries have organisations that can assist with substance risk assessment and

emergency planning that is required by a wide variety of legislation, such as the National Chemical

Emergency Centre in the UK, Brandweerinformatiecentrum voor gevaarlijke stoffen/Fire service

information centre for dangerous goods in Belgium.

In the UK, the UK Chemical Reaction Hazards Forum publishes reports of accidents on its web site.

[3] These accidents were, at the time, minor in nature, but they could have escalated into major accidents.

It is hoped that publishing these incidents will prevent "Re-inventing the Wheel". At present, (Dec 2008),

there are over 140 articles on the web site.

List of industrial disastersFrom Wikipedia, the free encyclopedia

This article lists notable industrial disasters, which are disasters caused by industrial companies, either by

accident, negligence or incompetence. They are a form of industrial accident where great damage, injury or

loss of life are caused.

Other disasters can also be considered industrial disaster, if their causes are rooted in the products or

processes of industry. For example, the Great Chicago Fire of 1871 was made more severe due to the heavy

concentration of lumber industry, wood houses, fuel and other chemicals in a small area. Some can be related

to engineering disasters when shortcuts in engineering design to reduce costs of construction and fabrication

leads to unexpected design failures.

The Convention on the Transboundary Effects of Industrial Accidents is designed to protect people and the

environment from industrial accidents. The Convention aims to prevent accidents from occurring, to reduce

their frequency and severity, and to mitigate their effects. The Convention addresses primarily industrial

accidents in one country that affect the population or the environment of another country. The Convention was

drafted following the Seveso disaster and Sandoz disaster.

Defense industry[edit]

August 9, 1965: Little Rock AFB in Searcy, Arkansas. 53 contract workers were killed during a fire at

a Titan missile silo. The cause of the fire was determined to be a welding rod damaging a hydraulic hose

allowing hydraulic vapors to leak and spread throughout the silo, and ignited by an open flame.

April 10, 1988: Ojhri Camp. A military storage center in Rawalpindi Pakistan exploded, killing more than

1,300 people.

Accidents in the chemical industry can have a devastating impact - and lead to changes in legislation

IT TAKES a matter of seconds to sully the reputation of the chemical sector.

Despite producers boasting an enviable safety record compared with most other major industries, a solitary accident can send shockwaves around the globe and have major repercussions that linger for years to come.The very nature of the chemicals handled or produced at these sites means that every incident can be potentially fatal. It also resulted into ill health and the severity can be marked for years.

. Just look at the number of victims - the death toll and the huge number of injuries - as well as awareness to the public," he says.

The pollution of the Rhine following the Schweisehalle, Switzerland, incident in 1986 emphasised the need to tighten the existing legislation further, adds Christou.

"It was after Bhopal that the industry established the Responsible Care program, and the authorities developed the Risk Management Program rule in the US and the Seveso II directive in Europe [in 1996]..

Preparedness

Communication underlies the work of this period. During the pre-disaster

phase, people and organizations should collect information, and put it to use

while they learn to work together, if they are to create effective .

Information must also be collected about the resources available to respond. The organizations which should be involved at this stage include public and private agencies devoted to emergency responses, such as the fire and police departments, civil

defence; relief agencies such as the Red Cross; hospitals,144 Methods for Assessing and Reducing Injury from Chemical Accidents ambulance and other medical services; the mass communications media;

The preparedness stage involves a high degree of coordination and cooperation among all these agencies, because preparedness plans are not simply formal written documents, but rather involve: 'all those documents, activities, practices, formal and informal agreements, and associated social arrangements.

Whether to Warn :Unless the danger is very serious, clear and imminent, this decision will be based upon probabilistic, often ambiguous information. How likely it is that there will be an impact with serious consequences if there is no warning, has to be balanced against the disruption, 'the loss of time and money. . .

What is a Good Warningtwo pieces of information: '(1) the existence of danger, and (2) what can be done to reduce the effect of danger.
