Environmental Controls

1) Fire Damage:

Controls for Environmental Exposures:

  • Installation of both automatic and manual fire alarms
  • Fire suppression system.
  • Manual fire extinguishers
  • Fireproof Walls; Floors and Ceilings
  • Fire exits should be clearly marked..
  • All staff members should know how to use the system.        

2) Documented and Tested Emergency Evacuation Plans:

Relocation plans should emphasize human safety, but should not leave information  processing  facilities physically unsecured. Procedures should exist for a controlled shutdown  of  the computer in an emergency. In all circumstances saving human life should be given paramount importance.

3) Smoke Detectors:

  Smoke detectors are positioned at places above and  below  the  ceiling tiles. Upon activation, these detectors should produce an audible  alarm  and  must be linked to a monitored station (for example, a fire station).

4) Wiring Placed in Electrical Panels and Conduit: 

      Electrical wires are always a risk. To reduce the risk of such a fire occurring and spreading, wiring should be placed in the fire-resistant panels and conduit. This conduit generally lies under the fire-resistant  raised floor in the computer room.

5) Power Spikes​ Controls

  • Using Electrical Surge Protectors.
  • Un-interruptible Power System (UPS)/Generator
  • Voltage regulators and circuit breakers
  • Emergency Power-Off Switch

6) Water Damage Controls

  • Wherever possible have waterproof ceilings, walls and floors;
  • Ensure an adequate positive drainage system exists;
  • Install alarms at strategic points within the installation;
  • In flood areas have the installation above the upper floors but not at the top floor;
  • Water proofing; and
  • Water leakage Alarms.

7) Pollution Damage & Others

  • The major pollutant in a computer installation is dust. Dust caught between the surfaces of magnetic tape / disk and the reading and writing heads may cause either permanent damage to data or read/ write errors.
