*3.2. Procedures*

The survey included staff in different positions, for example, operational staff in the field, and staff officers from levels of management. Informed consent was obtained from the organisers, and each respondent was provided with written information. They were informed about confidentiality and the opportunity to withdraw from participation in the survey at any time. The data were collected with informed verbal consent.

Self-administered questionnaires collecting data were distributed. The questionnaires were coded for each exercise, and the completed questionnaires were collected anonymously by the authors. The questionnaires from the ONSOs were in paper form, and the later was outlined as web-based documents, while the questionnaires of the OFFSOs were web based.
