classify and explains the types of hazards associated with industrial environment.


industrial hazards consist of four principle hazards. this is because industries employ many different processes involving a wide range of different raw materials, intermediates, waste products and final products. the hazards encountered are fire, explosion, toxic release and environmental damage.


fire: this is the most frequent of the hazards however the consequences are generally less. the effect of fire on people usually takes the form of skin burns and is usually dependant on the exposure time and the intensity of the heat. fire can also produce toxic fumes like acrolein, carbon monoxide and cyanides. physical structures can be damaged either by the intensity of the heat or combustion. it may also have an effect on essential services like power and instrumentation which can cause an escalation of the incident


explosion: explosions are usually heard from far away as a ‘bang’. this is the result of a shock wave. this overpressure can kill people but usually the indirect effects of collapsing buildings, flying glass and debris causes far more loss of life and severe injuries. there are different types of explosions which include gas explosions and dust explosions. gas explosions occur when a flammable gas mixes with air and is exposed to an ignition source. dust explosions occur when flammable solids, especially metals, in the form of fine powders are intensively mixed with air and ignited.


toxic/chemical release: sudden releases of toxic vapours have the potential to cause death and severe injuries several miles from the release point. they are carried by water and air. their release into public sewage systems, rivers, canals and other water courses, either directly or through contaminated water used in fire fighting can result in serious threat to public. the number of casualties depends on the weather conditions, population density in the path of the cloud and the effectiveness of the emergency arrangements.


environmental damage: as well as having the potential for causing injury, loss of life and damage to property, the hazards of fire, explosion and toxic releases may pose a severe threat to the environment. release of other substances, not directly toxic to humans can cause major pollution problems. it is becoming increasingly recognized that damage to natural resources such as plant and animal life can have serious long term consequences.
