What are the risks indicated on the map?

The Dutch government has defined eighteen types of disasters. Thirteen of these are linked to a specific location. The following table shows the disasters involved and how these are indicated on the map.

The five types of disasters that are not shown on the map are: threats to public health (e.g. as a result of food poisoning), epidemics, extreme weather, failing utilities and remote disasters (e.g. a Dutch touring car that has crashed in Spain).

A risk object is indicated on the map if:

  • the consequences of an incident are such that when dealing with it, the joint deployment of emergency services is required; and
  • there may be many casualties.

The locations of risk objects can be indicated using the risk map on a topografische kaart [topographical map] or on a luchtfoto [aerial photo].

If you see a red symbol near to your house or office, that means that this is a location where a risk source exists with hazardous substances. A green symbol on the map indicates buildings where there may be many people who may need help in the case of a large-scale incident. Examples include hospitals, schools and day nurseries. Emergency services use this information to estimate the effect of any large-scale incident and how they can best prepare for such.
