Abstract
The risk of unsuitable placement of LPG (i.e. Liquid Petroleum Gas) propane-butane filling stations in densely populated areas or in the immediate vicinity of busy roads may have, in the event of fire or explosion, incalculable consequences in terms of fatal or serious accidents and cause considerable economic damage to property. As a consequence, the positioning of any such LPG filling station should always be of crucial importance already in the filling station planning stage and its placement should be carefully assessed. The present paper aims at outlining a particular method of evaluating risks resulting from incorrect placement of an LPG filling station, including potential consequences. One such approach to assessment of installation safety of LPG filling stations is to implement the so called ALOHA screening method. This paper shall demonstrate practical implementation of the ALOHA screening, and that with regard to infrastructure, it is not always possible to find a suitable and safe location for LPG filling stations.
Highlights
The purpose of the following section is to describe, with the use of a model situation, the placement of an LPG filling station (Fig. 2) and to stress the importance of paying particular attention to safe placement of this installation for risks and incidents elimination with respect to the infrastructure, the occurrence of incidents and their adverse effects.The word ‘incident’ in the context of the presently discussed situation conveys the extraordinary conditions and impact on the affected area, as well as on general public
For practical modeling of the ALOHA screening, a fictitious LPG filling station situated in a populated urban area close to a shopping center was chosen
The ALOHA software application (Areal Locations Of Hazardous Atmospheres) is a dispersive model for Windows operating system that was developed by the United States Environment Protection Agency (US EPA) [2]
Summary
The purpose of the following section is to describe, with the use of a model situation, the placement of an LPG filling station (Fig. 2) and to stress the importance of paying particular attention to safe placement of this installation for risks and incidents elimination with respect to the infrastructure, the occurrence of incidents and their adverse effects. For practical modeling of the ALOHA screening, a fictitious LPG filling station situated in a populated urban area close to a shopping center was chosen. The location of the LPG filling station was specified by a 50-metre distance from the shopping center and 10 meters from the road with normal city traffic. The application of the ALOHA method will demonstrate the importance of resolving the matter of safe location for the LPG filling station prior to any construction works. The ALOHA software is available free of charge on the US EPA official website [3]
