The Power of Asking Pivotal Questions

Monitor Develop a routine for cleaning and monitoring the new temporary storage space, in order to prevent pests, fire, water and any other agents that could cause damage to the objects. 88 First Aid to Cultural Heritage in Times of Crisis | 1. Handbook Salvage After a post-event evacuation has been completed, damaged cultural heritage needs to be stabilised. Salvage is the systematic recovery of damaged cultural heritage objects, building fragments and decorative elements from a site negatively impacted by a hazard event. Salvage of movable cultural heritage involves an evacuation process similar to the workflow for post-event evacuation, with the inclusion of additional actions for the triage and stabilisation of cultural heritage material, designed to prevent further damage until professional intervention can take place. In the event of the partial or total collapse of a historic structure, salvage will also include the sorting of debris to recover original stone, brick or wooden elements to be used for future reconstruction. Depending on the emergency, you may find that it is necessary to undertake both evacuation and salvage together; or you may find that nothing is damaged at a compromised site, and that post-event evacuation will be required to decontaminate the site.

Security and stabilisation 89 Salvaging a flooded historic archive: Chile In June 2016, unseasonably heavy rainfall caused flash floods in extensive parts of Talca, a city 250km south of Santiago. Drainage failure resulted in the flooding of a documentation centre in the basement of a building at the Universidad de Talca that housed an important collection of old manuscripts and original sheet music. The water rose to a height of 50cm before the rain ceased. All of the books and manuscripts located on the lower shelves, and those that were stored in boxes on the floor were saturated, affecting approximately 5000 books and manuscripts in total. The water was pumped from the basement and the floors dried as soon as possible, before installing fans and dehumidifiers. Due to the large volume of objects affected, the decision was made to freeze them until they could be dried properly. Objects were prioritised according to degree of saturation and arranged so that they could be dried or frozen. Refrigerated trucks and freezers were borrowed from a fruit export company. Wet books were separated gently and placed in individual plastic bags to prepare them for freezing before arranging them into boxes for storage. The books were then transported in the trucks to the freezer facility, where they were stored for ten months at -24°C. The frozen books were removed from the freezers in small quantities and thawed carefully. Eventually, all of the books and manuscripts were thawed and dried. As a result the disaster planning and subsequent quick response, all of the objects were recovered successfully.
