Water is one of the agents of deterioration. Its effects can be seen in these flood-damaged library books. The 'ten agents of deterioration' are a conceptual framework developed by the Canadian Conservation Institute (CCI) used to categorise the major causes of change, loss or damage to cultural heritage objects (such as collections held by galleries, libraries, archives and museums). [1]
The Agents of Deterioration are the ten primary sources of damage to heritage objects and buildings comprised in a comprehensive list by the Canadian Conservation Institute. The Agents are physical forces, fire, pests, light (ultraviolet and infrared), incorrect relative humidity , thieves and vandals, water, pollutants, incorrect temperature ...
The type of events included in an organisations disaster preparedness plan will depend on their risk appetite. Examples of disasters affecting cultural organisations and cultural heritage are given below using the 'agents of deterioration' category headings. Natural disasters are usually dictated by region and climate.
Different deterioration phenomena often occur simultaneously. [7] Inappropriate temperature is another source of deterioration. There are several ways that temperature can cause object degradation. One being that the temperature is too high: this excess heat can cause chemical, physical, and biological phenomena.
Agents of deterioration can include mishandling, light, fluctuating humidity, dust and pollution, fire, water, gas and heat, neglect, and pests and other vermin. [33] Inherent vice is "the quality of a material or an object to self-destruct or to be unusually difficult to maintain". [ 34 ]
The agents of deterioration are ten key factors that are identified to contribute to the risks faced by artifacts. [9] While just one of these dynamics could cause irreversible damage, improper conditions or events could cause more than one of them to occur in tandem, effectively multiplying problems.
There are ten main agents of deterioration which should be monitored on a regular basis and guarded against as a part of collections maintenance. These are temperature, incorrect relative humidity, light, dust & pollutants, pests, physical force, theft & vandalism, fire, water, and custodial neglect. [ 6 ]
The Canadian Conservation Institute lists ten agents of deterioration that play a role in damaging an object or work of art. [4] While all of these agents play a role in damaging a painting over its lifetime, five primary agents are involved in the degradation of an artwork's canvas and its pigment layers.
