If a fire broke out in an automation console, you would first secure the power and then proceed to use which of the listed hand portable fire extinguishers?

Correct Answer: Option A — CO2

CO2 is the preferred extinguishing agent for electrical fires in automation consoles because it is non-conductive and leaves no residue. Unlike water or foam, which could cause short circuits or damage sensitive electronic components, CO2 displaces oxygen to smother the fire without harming the delicate internal circuitry.
