Fire safety measures at data centers are under scrutiny following incidents that resulted in extensive equipment damage and major disruptions to digital services.

In September, a data center fire in Singapore disrupted numerous technology companies and damaged critical infrastructure, including battery rooms and power supply rooms. In the same month, India's largest telecom provider experienced a nationwide network outage due to a blaze at one of its data centers.

A similar incident two years ago at a data center in Pangyo, South Korea, engulfed batteries used in backup power systems, leading to a prolonged outage.

Many of these fires have been linked to the widespread use of lithium-ion (Li-ion) batteries in uninterruptible power supply (UPS) systems, which provide backup power for critical IT infrastructure during power outages.

“Li-ion batteries, while highly efficient for energy storage, pose a fire risk when the lithium gas is exposed to oxygen,” says Andrew Green, Regional Data Center Practice Lead, Asia Pacific, JLL. “The larger the data center, the more Li-ion batteries there will be.”

Despite the persistent threat of data center fires, there is still no global regulatory standard for data center fire safety.

Individual countries, such as the U.S. and UK, have their own regulations. The National Fire Protection Association (NFPA) provides guidelines in the U.S., while the Building Safety Act 2022 governs fire safety in the UK.

“But in most regions, data centers still operate under building regulations designed for general industrial facilities,” says Green.
