Preserving Important Documents with Nitrogen Gas

The process of document preservation using nitrogen gas (Nitrogen Gas Preservation) is a method employed in the conservation of valuable documents to prevent deterioration from exposure to oxygen or unsuitable environmental conditions.

Using nitrogen for document preservation offers several advantages, including:

Prevention of Chemical Reactions
Nitrogen is an inert gas that does not readily react with other substances. This means it will not cause documents to deteriorate through chemical reactions. Additionally, the process of nitrogen fumigation displaces other gases that could contribute to degradation.

Reduction of Mold and Insect Growth
By reducing the oxygen levels during the process, the environment becomes inhospitable for the growth of mold and insects that may damage documents, such as paper-eating insects or fungi that thrive in high humidity conditions.

Balanced Humidity for Storage
Nitrogen can be used in climate-controlled rooms to maintain optimal humidity levels. If the humidity is too low, documents may become brittle and break; if too high, documents may become soft and tear easily.

How Nitrogen is Used for Document Fumigation

Packaging or Storage Areas:
The packaging or storage areas used for nitrogen fumigation must have systems in place to control temperature, humidity, pressure, and gas circulation. The storage environment must be airtight, meaning no air can enter or exit. This allows the nitrogen gas to replace the room air, reducing the presence of oxygen and other gases.

Time Control and Monitoring:
The fumigation process must be carefully timed and monitored to ensure that no other gases remain in the area, as these could pose a risk to the documents.

Benefits of Using Nitrogen for Document Preservation
Safety for Documents and Users
Nitrogen does not damage the material or content of the documents, and it is a non-toxic gas, which makes it safe for users as well.

No Residual Chemicals
Nitrogen is a colorless, odorless, and non-toxic gas, leaving no harmful residues on the documents.

Extended Document Lifespan
By reducing factors that contribute to deterioration, such as moisture and insect damage, nitrogen helps extend the lifespan of important documents.

Considerations
While nitrogen preservation is an effective method for prolonging the life of important documents, such as historical or governmental records, it is a long-term investment. The cost of nitrogen gas systems, including the construction of airtight storage areas, can be high. Therefore, it is important to choose a reliable nitrogen gas generator manufacturer or service provider. After-sales services, including maintenance and spare parts availability, should also be a priority.

Insects and Document Degradation

Insects are a major cause of document degradation. Many documents are made from organic materials such as paper, cloth, leather, and fibers, which attract insects. These pests, such as termites, cockroaches, silverfish, bookworms, and mites, consume the organic materials, leading to damage.

Document Fumigation
Fumigation is one method for eliminating pests. Documents that are received by national archives or other storage facilities must be fumigated with nitrogen gas before being stored. The fumigation process uses a vacuum system that removes air from the fumigation chamber and replaces it with nitrogen, reducing the oxygen level to a point where pests and their eggs cannot survive. Nitrogen is non-toxic, odorless, and non-flammable, leaving no harmful chemicals on the documents, making it safe for both workers and users of archival materials.

Environmental Control in Document Storage
Since nitrogen fumigation does not leave toxic residues, it is important to store documents in an environment where conditions such as temperature, humidity, and cleanliness are strictly controlled. This helps prevent pests from returning and damaging the documents. Regular inspections and environmental monitoring are essential to ensure the preservation of documents.
