Goal and impact
With the advent of the Environment Act, a number of things are changing around external safety policy. Vulnerable buildings and locations (KGLs) are buildings and locations that governments must provide extra protection against external safety risks. External safety risks can be summarised as risks resulting from activities involving hazardous substances. Such risks include, for example, a fire, (toxic) gas clouds or danger of explosion. To assign a particular vulnerability, competent authorities (usually municipalities) can use an IT facility that makes a vulnerability proposal based on a number of criteria. Based on that proposal, a competent authority can then set the vulnerability level.
Considerations
Many of the criteria applicable to a building or location are already recorded in various registers. The automated application of the trade-offs simplifies and speeds up the process of determining and publishing vulnerability levels. There are effectively no drawbacks, as this is a tool without direct consequences.
Human intervention
The results of the algorithm are verified and confirmed by the Competent Authority before publication in the External Safety Register is approved.
Risk management
No risks have been identified for applying this algorithm.
Legal basis
The Quality of the Living Environment Decree (BKL), Annex VI, https://wetten.overheid.nl/BWBR0041313 contains the basis for determining vulnerable buildings and locations.

Elaboration on impact assessments
No impact tests (DPIA or IAMA) have been carried out because this concerns the automated application of rules. Moreover, the results never lead directly to a decision or determination. Personal data does not apply.
Operations
Data
Data used in applying this algorithm are the use functions of buildings from the BAG (Basic Registration of Addresses and Buildings) and qualifications from the Chamber of Commerce Trade Register.

Technical design
The algorithm assigns vulnerability levels to buildings and locations based on properties and associated norm rules.
The properties taken into account are:
- the number of persons present simultaneously;
- the duration of presence of persons;
- the extent to which persons can bring themselves to safety in the event of an incident.
There are 9 different use functions whose vulnerability needs to be determined:
- residential function
- meeting function
- office function
- industrial function
- accommodation function
- sports function
- retail function
- education
- other user functions
The user functions are obtained from the Basic Addresses Buildings Register. These are updated monthly to the most recent data, after which the algorithm is applied again. The algorithm does a pre-fill and a cross-check in the Hnadelsregister (HR). The Competent Authority then receives a notification so that a decision on updating in the External Safety Register (REV) can be made.
Vulnerability levels are Highly Vulnerable, Vulnerable and Limited Vulnerability.
