Which type of fire suppression systems are preferred for historical buildings?

The preference for non-damaging agents, such as water mist or gas suppression systems, for historical buildings stems from the need to protect the integrity of the structure and its contents. Historical buildings often contain valuable artifacts, unique architectural elements, and materials that are sensitive to damage from excessive water or chemical agents.

Water mist systems utilize fine water droplets that can effectively extinguish fires with significantly less water than traditional sprinkler systems. This minimizes the risk of water damage to delicate structures and finishes. Gas suppression systems, such as those using inert gases or chemical agents specifically designed not to harm artwork or architectural features, can suppress fires without leaving residue that would require extensive cleanup or restoration efforts.

In contrast, foam-based systems, regular water sprinkler systems, and standard fire extinguishers can introduce significant water or chemical damage, which may not only destroy irreplaceable items but also compromise the structural integrity of the building. Thus, the use of non-damaging suppression agents is crucial in preserving both the building itself and its historical significance.
