Data center fire protection is the combination of fire prevention, detection, suppression, emergency planning and portable fire-extinguisher protection used to protect people, equipment and critical digital infrastructure.

Modern data centers contain dense concentrations of servers, electrical equipment, UPS systems, batteries, cabling and cooling infrastructure. When a fire occurs in these environments, the consequences can extend beyond the fire itself to equipment damage, downtime and disruption of critical services.

What Happened at the Amazon Data Centers in Ohio?

Futurism reported that first responders in Jerome Township, Ohio, had responded to a combined 84 emergencies involving two Amazon data centers since the projects were approved in 2021.

The reporting also described an April 2025 fire at an Amazon facility that resulted in approximately $50 million in damage and kept first responders occupied for more than 24 hours.

Why Do Data Centers Require Specialized Fire Protection?

Data centers are not ordinary office environments. They can contain large amounts of electronic equipment and electrical infrastructure operating continuously.

A Data Center Fire Can Mean More Than Property Damage

A fire inside a data center can affect servers, power systems, networking equipment, cooling systems and other infrastructure. Smoke, heat and extinguishing agents can also create secondary damage or cleanup requirements.

FM's current data-center loss analysis reports that fire represented 42.3% of loss cost compared with 10.9% of loss frequency in its historical engineering-peril data.

The important takeaway is not that fires are the most common data-center loss event. It is that when fire occurs, its financial consequences can be disproportionately significant.

What Does Comprehensive Data Center Fire Protection Include?

What Fire Extinguisher Is Used in a Data Center?

There is no single extinguisher that is automatically correct for every area of a data center.

For sensitive electronic equipment, carbon dioxide (CO2) and halogenated-agent clean-agent extinguishers are specifically addressed in NFPA 75 for electronic-equipment protection.

These agents can be valuable where avoiding the powder residue associated with conventional dry chemical extinguishers is an important consideration.

Other parts of a data center may contain different hazards, meaning extinguisher selection should be based on the actual area, equipment, fire rating and applicable requirements.

Halotron Clean-Agent Fire Extinguishers for Sensitive Equipment

Halotron I clean-agent extinguishers are designed for applications where minimizing residue and secondary cleanup is important. Tesla Fire Systems supplies several Amerex Halotron models for sensitive electronic and electrical environments.

CO2 Fire Extinguishers for Electrical and Electronic Equipment

Carbon dioxide extinguishers are designed for appropriate Class B and Class C fire hazards and do not leave the powder residue associated with dry chemical extinguishers.

Are ABC Fire Extinguishers Appropriate for Server Rooms?

ABC dry chemical extinguishers are widely used for appropriate Class A, B and C hazards, but that does not make them the automatic choice for every room inside a data center.

Dry chemical agents leave powder residue. Around sensitive IT equipment, that can create additional cleanup and contamination concerns following discharge.

The practical lesson is simple: choose the extinguisher for the hazard and the equipment being protected, not simply because it is the most common extinguisher available.

UPS and Battery Fire Protection

UPS systems and batteries are important parts of modern data centers because they provide backup power for critical loads.

FM research has specifically examined lithium-ion battery fire and explosion hazards associated with UPS systems in data centers. Lithium-ion battery failures can involve thermal runaway and may require fire protection strategies specifically suited to energy-storage systems.

Battery areas should therefore be evaluated separately from ordinary server-room hazards, with consideration given to battery technology, detection, cooling, suppression and emergency response.

Why NFPA 10 and NFPA 75 Matter

NFPA 75, Standard for the Fire Protection of Information Technology Equipment, addresses fire protection for IT equipment areas, including portable extinguishers and detection and suppression systems.

NFPA 10, Standard for Portable Fire Extinguishers, addresses the selection, installation, inspection, maintenance and testing of portable fire extinguishers.

These standards reinforce an important point for facility operators: a fire extinguisher should be selected and maintained as part of the facility's overall fire protection strategy.

What Should Data Center Operators Look for in a Fire Extinguisher?

Data Center Fire Protection Is About Protecting Critical Infrastructure

The recent Amazon data-center incidents reported in Ohio highlight the practical challenges that large facilities can create for emergency responders and operators.

The broader fire-protection evidence shows why data centers require a layered approach that considers prevention, detection, suppression, emergency response and the correct portable fire extinguishers for each hazard.

For areas containing sensitive electronic equipment, the choice between dry chemical, CO2 and clean-agent protection should be based on the actual hazard, equipment, fire rating, listing and applicable requirements.

In a facility where expensive equipment supports critical digital operations, the right fire protection equipment is part of protecting the operation itself.
