In this article we’ll look at what is preventive conservation and what is the origin and importance of this concept for the preservation of Historical Heritage.
Preventive Conservation focuses on how to safeguard Cultural Heritage by anticipating the factors that can influence its degradation and taking the necessary measures to preserve both tangible and intangible Historical and Cultural Heritage.
When we refer to Historical Heritage or Cultural Heritage we are talking about much more than objects of artistic value, as you can read in the article What is Cultural Heritage.
We’re not just talking about built historical heritage, artistic monuments, but also works of art and all kinds of cultural manifestations – what is known as intangible heritage.
The concept of heritage continues to change, just like society itself, ways of life and ways of thinking and acting.
What is Preventive Conservation
The topics we are going to cover are:
1 - What is preventive conservation in its origin and how this concept arose. 2 - What are the 5 basic principles on which Preventive Conservation is based. 3 - What are the objectives of Preventive Conservation. 4 - What is Preventive Conservation as a set of procedures to safeguard the Heritage.
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 of Cultural Heritage
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.
1 – Common sense.
2 – Memory.
3 – Intuition.
4 – Reason.
5 – 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.
And those are in the area of Preventive Conservation.
To answer the question what is preventive conservation we have to look carefully at all the aspects that we can control without direct intervention on the object.
And we have to relate the concept with the risk assessment and risk management methods.
Read the post about risk management.
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.
what is Preventive Conservation
What is the idea behind the concept of preventive conservation?
The idea behind 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.
