What Is the Biggest Threat to a Data Center?
In addition to power outages, fires, and cooling system failures, flooding and stormwater intrusion are also among the most critical risks facing data centers.
Once water enters a data center, it can affect server rooms, UPS rooms, electrical rooms, battery rooms, diesel generator rooms, and chiller plants, resulting in equipment shutdowns, business interruptions, and even significant financial losses.
1. Flood Protection Requirements in GB 50174
The Code for Design of Data Centers (GB 50174-2017) clearly states that data centers should be located away from areas exposed to natural hazards such as flooding.
Key flood protection requirements include:
In other words, flood protection is not a temporary measure. It is a fundamental safety requirement that must be considered during the design stage of a data center.
2. FM 5-32 Establishes Higher Standards for Data Center Flood Protection
FM Global Data Sheet 5-32, Data Centers and Related Facilities, introduces more stringent flood protection requirements from a property loss prevention perspective.
Key requirements include:
The FM approach is straightforward: flood protection is not simply about removing water after it arrives. The primary objective is to prevent water from entering critical areas in the first place.
3. Why Do Data Centers Need Flood Doors?
Many data centers already have drainage channels, sump pits, and drainage pumps. However, these measures are designed primarily for water removal.
The real risk is that water may enter through building openings before drainage systems can effectively respond.
Common points of water intrusion include:
For this reason, data center flood protection should evolve from a drainage-only approach to an integrated strategy that combines: Flood Barrier + Drainage + Alarm + Emergency Response
4. The Value of FM Approved Flood Doors
Shanghai Weiwang Technology Co., Ltd. provides FM Approved Flood Door solutions designed for critical entrances and important equipment rooms within data centers.
The advantages of FM Approved Flood Doors include:
1. Performance Verified Through Independent Certification
Compared with conventional flood barriers, FM Approved Flood Doors are supported by a clearly defined and independently verified performance standard, making them suitable for protecting high-value assets.
2. Designed for Critical Data Center Areas
They can be installed at personnel entrances, logistics entrances, equipment access points, underground ramps, electrical rooms, UPS rooms, battery rooms, diesel generator rooms, and other critical locations.
3. Supports Insurance and International Compliance Reviews
For projects that follow FM loss prevention requirements, FM Approved products are more readily incorporated into risk improvement and risk management programs.
4. Complements Both GB and FM Requirements
GB standards focus on site selection, elevation, and flood resistance.
FM standards emphasize protection against 500-year flood events, stormwater runoff, underground flooding, and emergency preparedness.
Flood doors are a key engineering control measure for protecting building openings against water intrusion.
5. Recommended Flood Protection Strategy for Data Centers
Conclusion
Data center flood protection should not rely solely on drainage systems.
Effective flood protection begins by preventing water from entering the building.
From GB 50174-2017 to FM 5-32, industry standards consistently emphasize the need to address flood risks, stormwater runoff, and underground water intrusion before they become operational threats.
For critical entrances and essential equipment rooms, the installation of FM Approved Flood Doors is an important measure for improving the overall resilience and reliability of data center flood protection systems.
