Casualty recorders should assess which kind of data to collect (or not) according to the levels of protection they can guarantee it and according to the necessity to hold this data.
As more detailed data is collected, the level of protection for this data has to increase accordingly. Where it is not possible for casualty recorders to provide adequate protection, certain data should not be collected, as this would risk endangering those who collected the information, those who provided it, and other persons. This assessment is particularly important when it comes to the collection of sensitive data on the basis of which people are discriminated against (e.g. religion, ethnicity, sexual orientation, kinship).
