It translates into a strengthening of measures of vigilance, prevention and protection and is intended to be of limited duration. It may be activated over the whole territory or, if it is necessary to reinforce safety measures on an occasional basis, over a limited geographical area and/or in certain sectors of activity.

It is placed under the responsibility of the State Prosecutor in Luxembourg City.
