What is the best type of fire extinguisher for sensitive electrical equipment?

If you have sensitive electronic equipment, such as in a computer room or data center, using a water or a dry chemical fire extinguisher can cause as much damage as a fire itself. Instead, use a clean agent fire extinguisher such as a Cleanguard FE 36 (made by Ansul) or a Halotron I (made by Amerex) fire extinguisher.

Halotron I – Halotron I discharges as a rapidly evaporating liquid that leaves no residue. It does not conduct electricity and is suitable to fight Class A, B, and C fires.

Cleanguard FE 36 – the Cleanguard FE 36 is a replacement for Halon 1211. The Cleanguard extinguisher has comparable performance and efficiency to Halon 1211 but is less toxic and has zero ozone depletion potential.
