Principle of design in protecting the objects in museums on the sections they are exhibited, restoration areas or stores includes such solutions not to cause damage to the objects. Therefore, especially gaseous extinguishing (FE 227 or FE 25) or “high pressurized water mist“ systems are preferred.

|
It is known that gaseous systems do not damage any objects or artworks. Water mist system is used in many museums; however, an analysis should be made in advance to use these systems in such areas containing certain works which may be damaged by humidity. It is estimated that low pressurized water mist system would be more risky than high pressurized ones since water particle diameters of them are greater than high pressurized ones.

|
If the objects are exhibited at windows or special glass cabinets, gaseous extinguishing systems are easier and cheaper. In window type exhibitions, micro extinguishing systems are preferred since they are applied easily and do not attract attention of visitors rather than other systems.
|
|
|
|
Gaseous extinguishing systems designed by the method of “Fully filling the volume by gas” (Total Flooding) are preferred for protection of objects and works which are exhibited in special rooms or waited before/after the exhibition or locate in the areas where restoration of works is made.
