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?
AI Explanation
The correct answer is A) CO2.
In the event of a fire in an automation console, the first step is to secure the power supply to the affected equipment. This is to prevent the fire from spreading or intensifying due to continued electrical supply. Once the power is secured, the appropriate fire extinguisher to use is a CO2 (carbon dioxide) extinguisher.
CO2 extinguishers are effective for electrical fires because they smother the fire by displacing oxygen, without leaving any residue that could damage sensitive electronic equipment. The other options, such as soda acid, foam, or dry chemical extinguishers, are not recommended for use on energized electrical equipment as they can cause further damage.
