Risk analysis impact release of hazardous substances

In environmental science it is called environmental risk to the possibility of damage or environmental catastrophe occurs due to a natural phenomenon or human action. The environmental risk represents a particular field within the broader risks that can be assessed and prevented field.

The risks can be classified as:

Natural hazards. They are associated with internal geological phenomena, such as volcanic eruptions and earthquakes, or falling meteorites. Floods, although due to natural climatic causes, often dependent risk of the presence and quality of infrastructure such as dams that regulate the flow, or roads that act as dams, which can exacerbate its consequences.

Anthropogenic risks. They are produced by human activities, although natural circumstances can condition their severity.

The procedure for Environmental Risk Assessment is an instrument of a preventive nature through the systematic application of policies, procedures, analysis, evaluation and risk control in order to protect society and the environment anticipating the possibility of accidental releases of hazardous substances by sus-infectious biological in facilities and corrosive, reactive, explosive, toxic, flammable or characteristics evaluates their potential on the environment in case of an unwanted event, so that it can be prevented, mitigated or restored impact.

In this context, it is understood as an accident of high environmental risk an explosion, fire, leakage or sudden spill resulting from a process in the course of activities of any facility and pipeline, which involved one or more materials or hazardous substances that pose serious danger (immediate or delayed, reversible or irreversible manifestation) for people, property and the environment. These types of accidents are regarded as major accidents and include the following types:

  • Any release of a hazardous substance, in which the total amount released is greater than that has been set as a threshold or limit (amount of report or control).
  • Any greater fire leading to elevated thermal radiation at the site or limit entire plant exceeding 5 kW / m2 for several seconds.
  • Any explosion or gas that can cause pressure waves.
  • Any explosion of a reactive or explosive substance that can affect buildings or plants in the immediate vicinity, as well as to harm them or render them inoperative for a while.
  • Any release of toxic substances, in which the amount released may be sufficient to achieve a concentration equal to or above the level that poses an immediate danger to life or human health in surrounding areas to the emitting source.

In the case of transport, it is considered as an accident involving the leakage or spillage of significant quantities of hazardous materials or waste that can cause severe effects on the health of the population and / or the environment.

Biogroup researchers have extensive experience in the running of mathematical models necessary for the evaluation of the probability of occurrence of these events and the severity of its consequences.
