DCP Superfine Fire Extinguishing Device in Archival Repository

The First World War (1914-1918) and the Second World War (1939-1945) burned many cultural relics and archives, after the Second World War, the archival undertaking developed and grew stronger and stronger, and many archival repository buildings were built, but even though the war is passed already, the archival repository is still easy to get fire, so it is important how to make fire protection for the archival repositories, how to improve fire extinguishing technology for archival repository (archives) is a new challenge in front of us.

Superfine ABC dry chemical powder fire extinguishing device is a good fire extinguishing agent that can suspended in the air and can bypass obstacles to spread to all corners, to extinguish the fire by total flooding or local application, develop dry chemical powder fire extinguishing technology to automatic fire suppression, it is a coalition of nanotechnology and dry chemical technology, it is stand for the highest dry chemical powder fire extinguishing level and its developing direction.

Fire Protection Technology Requirement for Archival Repository and Its Application

Archival repositories have requirements for fire extinguishing technology, the requirements are as below:

• A. have a special requirement for a fire extinguishing agent, it should have no corrosion, be non-toxic, clean agent, and be eco-friendly, such as the fire extinguishing agent should have no corrosion to file carrier like paper, micro fabric, film, tape, disk etc, should not affect these file carriers.
• B. has a special requirement for fire extinguishing methods, it requires the suppression of the fire at its early stage and quickly put out, to prevent the archival repository suffer from larger damage, so requires all the fire suppression devices to be sensitive and reliable.

Halon-based fire suppression agents have been popular since the 1970s, because of their excellent fire performance, after halon fire extinguishing agents have been forbidden to be put into use since then the following fire suppression system can be suggested to put into use for archival repository applications.

Archival repository fire extinguishing technology application situation

• 1. FM200 fire suppression system (hfc-227ea agent), its working principle is just similar to the halon fire extinguishing systems, belongs to the chemical fire suppression range, and it has a little corrosion to the skin, paper, glass, and precision instrument.
• 2. The carbon dioxide fire suppression system (CO2 system), belongs to the physical fire suppression range, its fire extinguishing efficiency is low and not be able to extinguish early-stage fires, it requires a cylinder storage room also need many cylinders with a pipeline, and also needs high pressure to work, also have a risk of asphyxia.
• 3. Aerosol fire suppression system (Strontium nitrate or potassium nitrate based), The aerosol fire suppression system is similar to the ABC dry chemical powder fire suppression system and fits for archival repository very well.
• 4. Inert Gas fire suppression system (IG541, IG01, IG100, IG55), its disadvantages are noise when it is discharging, high pressure and very dangerous also easy to get leakage, also need pipeline network and extinguishing fire slowly, high cost in installation and after-sales maintenance.
• 5. Water mist fire suppression system (high pressure or low pressure), which belongs to the physical fire suppression concept, uses water as a fire extinguishing agent to suppress the fire, it wet paper and cloth and makes and will damage the archives and files.
• 6. Superfine ABC dry chemical powder fire extinguishing system, the superfine ABC dry chemical powder fire extinguishing agent has an average particle diameter of no more than 20μm, this extinguishing agent is a clean agent and is an advanced fire suppression technology in the world, it is zero in Global Warming Potential value, zero in ozone-layer depletion potential value, non-irritating to human body skin, no corrosion and non-toxic to the protection objectives, also easy to clean up after discharge.

Product Recommendations

From the above description of different suppression systems, we strongly suggest installing a SUPERFINE ABC DRY CHEMICAL POWDER FIRE EXTINGUISHING DEVICE and its system in archival repositories (archives), libraries, museums, and any other important places.
