Difficulty: MediumPhysical Security Controls and Environmental Measures

An organization is renovating a central server room that houses high-density rack servers and critical core switches. The facility team needs to install a fire suppression system that immediately extinguishes electrical fires without leaving residue, causing short circuits, or damaging sensitive electronic components. Which of the following fire suppression systems best meets these physical environmental requirements?

  1. Clean-agent gaseous fire suppression systemAnswer
  2. B
    Wet-pipe automatic sprinkler system
  3. C
    Deluge open-nozzle fire suppression system
  4. D
    Class K wet chemical fire suppression system

Answer

Clean-agent gaseous fire suppression system
Clean-agent gaseous fire suppression systems utilize non-conductive gases (such as FM-200, Novec 1230, or Inergen) to extinguish fires by removing heat or oxygen without releasing water, chemical powders, or conductive residue. This protects live electronics and server infrastructure from water damage and short-circuit risks.

Step-by-Step Solution

1
Analyze the physical environmental requirements of the server room
Identified the need for a non-conductive, zero-residue fire suppression agent suitable for energized electrical and network equipment.
Water and chemical foam agents conduct electricity and cause permanent physical hardware corrosion and short circuits.
2
Evaluate fire suppression system types against electronic safety criteria
Clean-agent gas systems (FM-200, Novec 1230, or inert gases) smother or interrupt the chemical reaction of fires without water or residue.
Gaseous clean agents evaporate quickly, leave no chemical deposit, and do not conduct electricity.
