Question: 1 / 400

True or False? Using dry chemical extinguishers on electrical distribution equipment can cause more damage than the fire itself.

A True

Using dry chemical extinguishers on electrical distribution equipment can indeed cause more damage than the fire itself because the dry chemicals can be corrosive. When these chemicals settle on the electrical components, they may lead to deterioration and additional malfunctions, exacerbating the initial problem. Furthermore, some of the chemicals used in these extinguishers can conduct electricity, posing a risk of electric shock if not handled properly.

For electrical fires, it is generally recommended to use extinguishing agents that are suitable for electrical fires, such as carbon dioxide or specific class of extinguishers labeled as suitable for electrical fires. Therefore, while extinguishing the flames is essential, the method of extinction matters significantly, as it can lead to further complications or damage.
