Location of alarms to warn the population if there is a chemical risk in the case of an accident in premises nearby.

Indicates the level of danger for each municipality in relation to the transport of dangerous goods by rail mode. The level of danger takes into account not only the flow of dangerous goods but also the type of substances transported. The danger can be caused by a section of the railway network that crosses the municipal territory or by a section that, without crossing the territory, is at a distance equal to or less than 500 meters from the municipal territory.

Polygons which define the range of sound corresponding to the alarms. In accordance with each type of alarm, the sound radius covered can be 800 or 400 metres away from the siren, or maybe unidirectional, covering a distance of 700 m with a 70º opening.

The ZIF is defined as the minimum safety strip necessary to ensure the feasibility of self-protection of vulnerable elements in the context of an accident in the transport of hazardous materials. The extent of this area is conditioned by the necessary response time and the intensity of the effects of foreseeable accidents. The distances of the ZIFs for the scenarios of powerful toxic cloud, short-range toxic cloud, severe explosion, flammable cloud and puddle fire are set out in “The DGPC Technical Instruction on Reporting Minimum Conditions that they must comply with the new urban developments to be located within the areas identified as of chemical risk in the transport of dangerous goods by road and rail ”(ITMMPP, hereinafter). https://interior.gencat.cat/web/.content/home/030_arees_dactuacio/proteccio_civil/plans_de_proteccio_civil/plans_de_proteccio_civil_a_catalunya/02-plans-especials/transcat/document-pla-transcat-CAT.pdf

Delimitation of the theoretical areas of impact in the event of a major accident in an industrial facility handling hazardous substances and which is affected by the high level of severe accident regulations.

Indicates the level of danger for each rail section in relation to the transport of dangerous goods. The level of danger takes into account not only the flow of dangerous goods but also the type of substances transported. It also provides information on the annual tons transported for each section and information on the percentage of Hazardous Materials classified as toxic and / or highly flammable on the total Hazardous Materials transported by the section.

Indicates the level of danger for each section of road studied in relation to the transport of dangerous goods. The danger level takes into account, apart from the flow of dangerous goods, the type of substances transported and the EuroRAP index of the track section. Information is also given on the annual tons transported for each tranche and information on the percentage of hazardous substances classified as toxic and / or flammable and / or highly flammable on the total transported of Hazardous Substances of the section.

Indicates the level of danger for each municipality in relation to the transport of dangerous goods by road. The level of danger takes into account, not only the flow of dangerous goods, but the type of substances transported. The danger can be given by a section of the road network that crosses the municipality or by a section that, without crossing the territory, is at a distance of 500 meters or less from the municipal term.
