R&D Background
Definition of the scientific problem
Concerning disaster incidents fire occurs most often. In this section we are dealing with the environmental effects of the fire and the phenomena of secondary damage caused by the extinguishing of the fire of above ground atmospheric flammable liquid storage tanks.
The environmental protection laws and the related implementation directives apply to stationery known technologies with continuous emission and prescribe in detail the method for the measurement and calculation of each type of pollution emission and the permissible limits.
However, environment protection laws do not regulate the circumstances and methods of disaster recovery, since disaster incidents are characterized by the unpredictability of what will happen when and where, but refer this task to the competence of the disaster recovery laws. However, the law regulating disaster recovery tasks does not lay down environmental quality and quantity requirements, although properly chosen recovery technology may considerably reduce the load on the environment.
Another problematic area is that traditional, currently available fire fighting techniques such as the foam jet pipes, foam vessels, foam slides in case of semi-fixed extinguishing are not suitable for extinguishing with increased foam intensity, moreover their reliability is also very questionable and their potential failure will lead to a further disaster.
