Immediate damage can be minimized by reducing the vulnerability of the cultural heritage to the ca tastrophic events, i.e., by applyingpreventativemeasures aimeda tmitigating local critica l issues causedbychanges made to the buildings (containers) and the ageingof thestructural and facility systems. One of the most effective ways to prevent damage to the cultural heritage is increasing the knowledge of the communityabout suchgoods (including theirmain critical issues) and improving routine maintenance.

Deferred damage can be minimized by reducing the intervention timing, i.e., by improving the effectiveness of emergency interventions. Indeed, after the occurrence of a ca tastrophic event, the increased vulnerability of the historica l buildings and their contents leads to the possibility of further secondarycollapses anddamage. The reduction of the exposure time of thegoods reduces their vulnerability.
