olemus
ISO 22300:
inimene, kes võib olla vähem võimeline eriolukorra toimeid ette nägema, nendega toime tulema, neile vastu panema või neist toibuma;
selles dokumendis on kaitsetu inimene määratletud mitte nõrkuse iseloomu, vaid inimese isiklike asjaoludega eriolukorra ajal
= individual who might be less able to anticipate, cope with, resist or recover from the impacts of an emergency
Note. In this document, a vulnerable person is not defined by the nature of the vulnerability but by their personal circumstances at the time of the emergency.
