IT Service Management and Systems Audit

Which of the following is an appropriate approach to fire suppression for the server rooms of a data center?

  1. AElectronic equipment does not burn easily and there is little risk of fire, so no fire suppression system is needed in server rooms
  2. BOnly ordinary sprinklers that spray large amounts of water are installed, cooling the equipment along with the fire to stop it spreading
  3. CTo limit damage to equipment, a gas-based fire suppression system using inert gas or the like is used, with an alarm before discharge so that people can evacuate
Show answer and explanation

Answer: C. To limit damage to equipment, a gas-based fire suppression system using inert gas or the like is used, with an alarm before discharge so that people can evacuate

In server rooms, extinguishing fires with water can spread equipment failures and data loss, so gas-based fire suppression systems using inert gas or similar agents are widely used. Because gas-based systems put out fires by such means as lowering the oxygen concentration, they are designed to sound an alarm before discharge and release the gas after the people in the room have evacuated. They are combined with detectors that sense smoke at an early stage to keep damage small.

  • A. Fires can start in cable insulation, power equipment and the like, so a fire suppression system is necessary.
  • B. Large amounts of water can damage equipment that the fire has not reached and spread the damage.
  • C. Correct. A gas-based system is used, and people are evacuated before discharge.
