Sources of risk in the Netherlands, 1999
A map with the most high-risk companies in the Netherlands.

High-risk companies in the Netherlands
The most high-risk companies in the Netherlands are located in the Rijnmond area, along the River Maas in Limburg and near Amsterdam. The larger the circle, the more casualties there will be if the most severe accident were to occur at this location. This risk is caused by, in addition to the situation at the company in question and the extent and type of the activity, the number of people living in the vicinity. The probability of the worst accident scenario is not shown on this map.
Definition of group risk
The group risk is the probability of a disaster in which a proportion of the people present are killed. The level of risk that is still considered acceptable depends on the size of the disaster. An accident with 100 deaths results in more disruption, suffering and grief than an accident with ten fatal casualties. The limit set for the probability of a disaster with 100 deaths is therefore one hundred times lower than for a disaster with ten deaths.
