In a data center, the primary concern is the protection of sensitive electronic equipment, which can be damaged by water and certain types of extinguishing agents. The preferred choice, the ABC fire extinguisher, is a versatile option that is effective against multiple classes of fires, including those caused by ordinary combustibles, flammable liquids, and electrical equipment.

The ABC extinguisher uses a dry chemical agent such as monoammonium phosphate, which is non-conductive and suitable for tackling electrical fires without leaving harmful residues that could damage the equipment. This feature is particularly critical in data centers, where equipment is expensive and sensitive to moisture or chemical residues.

In contrast, water-based extinguishers could cause significant damage to electronic systems and are typically not recommended for environments with high-value electronics, which explains why the ABC extinguisher stands out as the best choice in this context. Aqueous Film Forming Foam, while effective for certain types of fires, is also not ideally suited for use in areas with electronic equipment due to moisture concerns. Lastly, dry powder extinguishers, while useful, can create a mess and leave residues that may be difficult to resolve in delicate data center environments.
