Häiriötilanne: Uhka tai tapahtuma, joka vaarantaa yhteiskunnan turvallisuutta, toimintakykyä tai väestön elinmahdollisuuksia ja jonka hallinta edellyttää viranomaisten ja muiden toimijoiden tavanomaista laajempaa tai tiiviimpää yhteistoimintaa ja viestintää. [2]
Disturbance is a threat or an occurrence which endangers security in society, capacity to act or the population’s living conditions. Co-operation and communication of the authorities and other actors on a wider or more intensive scale are needed to manage the situation [3]
