what is preventive conservation?

In this article we will see what is preventive conservation and what the origin and importance of this concept.

Based on the Preventive Conservation online course.


We relate Heritage with a people and their material or immaterial goods. Because of the timeless value they express, these goods must be taken care of as fundamental elements of society and culture.

The collective memory is the heritage of our ancestors and it should be transmitted to future generations.

This heritage must be preserved and restored and demonstrate, whenever possible, the beauty of the Past. Preventive conservation is a way of preserving our heritage, the memory of all of us.

what is preventive conservation | origin of the concept

In the late 20th century, Gary Thomson showed the importance of controlling the environment of collections by stating that “un mauvais restaurateur peut détruire un objet par mois. Un mauvais conservateur peut détruire une collection entière en un an ” (“A bad restorer can destroy an object within a month. A bad conservator can destroy an entire collection in a year”).

Gäel de Guichen will add something more to the matter of preserving the past, being the first to use the expression «Preventive Conservation». According to this author, what yesterday consisted of simple objects may today represent social and patrimonial collections.

what is preventive conservation to Guichen

His concept of preventive conservation means removing the objects or collections from insecure environments, through a set of attitudes aimed at safeguarding them. The application of these attitudes relies on some premises, which we can state:

– Common sense;

– Memory;

– Intuition;

– Reason;

– Ethic.

These assumptions in conjunction with scientific knowledge allow for a correct (direct or indirect) behaviour toward the objects. Interventions on works of art are considered direct performances, but such actions as controlling lighting, temperature, relative humidity (RH), rules of procedure, safety plans, preventive conservation plans, definition of spaces, hierarchies and tasks are considered indirect interventions.

what is preventive conservation | objectives

According to the «Professional Guidelines of European Confederation of Conservator-Restorers’ Organisations»  – «… Preventive Conservation consists of indirect action to retard deterioration and prevent damage by creating conditions optimal for the preservation of cultural heritage as far as is compatible with its social use.

Preventive conservation also encompasses correct handling, transport, use, storage and display. It may also involve issues of the production of facsimiles for the purpose of preserving the original.»

 

In other words, preventive conservation consists of indirect actions that slow down the deterioration and avoid damage by creating optimum conditions for the preservation of heritage legacy as much as possible. These actions go from correct handling, to transport, storage or exhibition, as well as the production of copies in order to preserve the original.


The idea behind the preventive conservation is, therefore, to be careful: to prevent preservation problems that might be found in the collections. And this assumption, inherent in preventive conservation, is common to all those who, directly or indirectly, deal with heritage value and whose actions aim to enhance, preserve and promote heritage.

In other words, care for the memory of the Past so it can have a Future.
