Solution
The correct option is BCO2
In case of fires that involve electrical equipment and inflammable materials, carbon dioxide (CO2) is used as extinguisher. It is heavier than
oxygen and covers the fire like a blanket. This way, the contact between the fuel and
oxygen is cut off, and the fire is controlled. Moreover, carbon dioxide does not harm the electrical equipment.
