Based on the provided image:
- A majority, being 65 percent or 20 incidents, were verified as actual fires.
- About 23 percent, or 7 events, were reported as fires but lacked verification.
- New data centers still under construction accounted for 6 percent or 2 incidents.
- In one instance, making up 3 percent, construction dust triggered the fire suppression system in an operational data center.
- Another single event, also at 3 percent, involved a disruption caused by testing of the fire suppression system.
These figures suggest an annual average of approximately 1.5 significant fire incidents at data centers.

Main Causes of Data Center Fires
Electrical systems are the most common ignition source in data centers, including wiring, heating and cooling equipment, and increasingly the lithium-ion batteries in UPS and battery rooms.
In general workplace fire data, ‘heating and cooling’ and ‘wiring’ are common ignition sources. Given their extensive use in data centers, these factors are assumed to be significant contributors to fires in such facilities.
How Often Do Fires Cause Data Center Outages?
Fires cause only a small share of data center outages: Uptime Institute identified 14 high-profile outages caused by fire or fire suppression systems from 2020 through early 2023, far fewer than outages from power and network failures.
Though the impact of data center fires can be significant when they do occur, the frequency of such events as a cause of outages is relatively low. In fact, data center fires are not among the most common reasons for downtime.

The statistics between 2020 and 2022 reveal that fires were responsible for an average of only 3% of all data center outages. Encouragingly, this figure has halved since 2020, indicating an improvement in fire prevention and safety measures within these critical facilities.
Data Center Fire Suppression Best Practices
Data centers are best protected by clean agent or inert gas suppression paired with very early smoke detection and zoned discharge, because water from sprinklers can destroy the servers it is meant to protect.
Effective fire suppression is critical to protecting data center assets and ensuring business continuity. While detection systems serve as your first line of defense, a well-designed suppression strategy determines whether a small incident remains contained or escalates into a catastrophic event.
Choose the Right Suppression Agent
Traditional water-based sprinkler systems present a serious problem for data centers. Water and sensitive electronic equipment simply do not mix. A sprinkler activation that successfully extinguishes a small fire can simultaneously destroy servers and networking equipment worth far more than the fire itself would have damaged.
For this reason, modern data centers have largely moved toward clean agent suppression systems. FM-200 and Novec 1230 are among the most widely adopted solutions, as both gases work by absorbing heat energy faster than the fire can generate it. They disperse quickly, leave no residue, and are safe for occupied spaces. Novec 1230 offers the added benefit of an exceptionally low global warming potential for environmentally conscious organizations.
Inert gas systems using nitrogen and argon provide another option. These reduce oxygen concentration to levels that cannot sustain combustion while remaining safe for humans. Though they require larger storage capacities, they have zero environmental impact.
Integrate Suppression with Detection and Zoning
Fire suppression works best when paired with early detection technology like VESDA, which can identify smoke particles before visible flames appear. This integration enables faster response times and can trigger suppression before a fire spreads.
Equally important is implementing zoned suppression rather than facility-wide systems. When a fire breaks out in one section, there is no reason to discharge expensive agents throughout the entire building. Zoning minimizes the impact of a discharge by limiting suppression to the affected room or zone, so a fire in one area doesn’t take down the whole facility.
Top Ways to Protect Against Data Center Fire Risks
The Uptime Institute’s recommended defenses against data center fires are very early smoke detection (VESDA), maintained suppression systems with fire barriers, and regular risk assessments.
According to research conducted by the Uptime Institute, the best practices to avert and safeguard against data center fires include:
- Detection: Use VESDA systems for early smoke detection.
- Suppression: Install fire barriers and maintain fire suppression systems. Consider ANSUL® clean agent systems, which use chemical agents instead of water to protect sensitive electronic equipment from collateral damage.
- Mitigation: Conduct regular risk assessments to address vulnerabilities.
Why ANSUL® Fire Suppression Systems Are Ideal for Data Centers
ANSUL clean agent systems suppress data center fires without water, protecting servers from the collateral damage that sprinkler discharge causes.
ANSUL® fire suppression systems offer a critical advantage for data center protection through their use of chemical agents rather than water. Industrial Fire provides data center fire suppression in Houston using exactly this type of clean agent technology.
Water-based sprinklers create a secondary disaster in data center environments. While they may extinguish flames, they simultaneously destroy the servers and networking equipment you are trying to protect. The recovery costs following water discharge often exceed the fire damage itself.
ANSUL® systems eliminate this risk. Their clean agent solutions suppress fires rapidly while leaving no residue on sensitive equipment. The agents interrupt combustion at a molecular level, extinguishing fires without collateral damage. Once the threat is neutralized, your equipment remains intact and operational, dramatically reducing downtime and recovery costs.

Protecting Your Data Center Investment
Data center fires are rare but expensive, so detection, clean agent suppression and scheduled inspection should be budgeted as one program rather than separate purchases.
While data center fires are relatively rare, their potential impact cannot be underestimated. Data centers are the backbone of our modern digital infrastructure, and as such, it is imperative that they implement comprehensive fire prevention, detection, and suppression strategies to mitigate risks.

Data Center Fire FAQs
How often do data centers catch fire?
Significant data center fires are rare. Data Center Dynamics counted 31 fire incidents at data centers between June 2003 and March 2021, about 1.5 a year, and only 20 of those were verified as actual fires.
Are data centers a fire hazard?
Data centers concentrate electrical load, batteries and cabling, so fire risk is real, but serious fires are uncommon.Uptime Institute identified only 14 high-profile data center outages caused by fire or fire suppression systems from 2020 through early 2023.
What happens when a data center catches fire?
Detection triggers suppression in the affected zone, power to that zone is typically cut, and services either fail over to another site or go offline. In the June 2026 Tata Communications fire in New Delhi, affected customer services took three weeks to fully restore.
What fire suppression system is used in data centers?
Most data centers use clean agent systems such as FM-200 or Novec 1230, or inert gas blends of nitrogen and argon, paired with very early smoke detection. These agents put out fires without the water damage a sprinkler discharge causes.
Are data centers fireproof?
No building is fireproof. Data centers limit fire damage with fire-rated rooms, early detection, zoned gaseous suppression and battery-room separation, so a fire stays contained to the area where it starts.
