Key standards for fire safety in data centers include:

1. NFPA 75 : A fire safety standard for data centers and computer rooms developed by the National Fire Protection Association, which provides detailed guidelines for equipment protection and fire prevention.

2. FMDS 5-32 : A data center fire risk management standard from FM Global that includes design and operational guidelines for fire prevention and loss minimization.

3. ISO 27001 : An information security management system standard that provides some guidance related to fire safety, including elements related to the physical security of data centers.

4. KFS-1280 : Korean fire safety standard, a domestic standard for fire prevention and loss minimization in data centers.

In addition, each country and region has various regulations and standards for fire safety in data centers.

NFPA 75 is the standard for fire protection of information technology equipment and is designed to ensure fire safety in data centers and computer rooms. The standard includes the following key topics:

1. Fire Risk Assessment : Assess the fire risk of your data center and provide guidance on taking appropriate protective measures.

2. Fire Prevention Systems : Specifies requirements for the installation and maintenance of fire prevention and suppression equipment, including sprinkler systems, fire detectors, and fire extinguishers.

3. Physical Protection : Provides guidance on the structural design of data centers to minimize damage from fire.

4. Emergency Response Plan : Includes procedures and plans for a quick and effective response in the event of a fire.

NFPA 75 plays a critical role in ensuring the safety of data centers and is a widely used international standard.

KFS-1280 is a standard designed to ensure fire safety in data centers, and is actually being applied in many data centers. For example, data centers in large IT companies and server rooms in financial institutions comply with this standard to minimize fire risks. In addition, KFS-1280 can be utilized in global data centers as it is based on international standards such as FMDS 5-32 and NFPA 75.

KFS-1280 and NFPA 75 contain a variety of technical standards to protect against lightning and surge events in data centers. The main contents are as follows:

Lightning Protection System :

Lightning protection : Install lightning rods and grounding systems to protect buildings and electrical equipment from lightning strikes. This follows international standards such as IEC 62305.

Grounding System : Discharges lightning current to the ground to prevent electrical damage. Grounding resistance should generally be maintained below 10Ω.

Surge Protective Device (SPD) :

SPDs are installed on power lines, communication lines, signal lines, etc. to protect electronic equipment from voltage surges caused by surges. These are based on international standards such as IEC 61643-11.

Ensuring electrical continuity :

Maintains electrical continuity between a building's metal structure and electrical equipment to minimize electrical damage caused by lightning.

Regular inspection and maintenance :

Regular inspection and maintenance are required to maintain the performance of lightning and surge protection systems. This is included in the recommendations of KFS-1280 and NFPA 75.

These standards play a critical role in increasing the safety of data centers and preventing fire and electrical damage.
