What is a common characteristic of Class "C" fires?

Class "C" fires are specifically defined by their involvement with energized electrical equipment. This characteristic is critical because using water or other standard fire extinguishing methods can pose a serious risk of electric shock or further damage to the electrical equipment. Therefore, it is essential to use appropriate fire extinguishers designated for Class "C" fires, such as those containing non-conductive agents like carbon dioxide or dry chemical agents. Recognizing that Class "C" fires involve energized electrical sources helps in understanding the appropriate safety measures and extinguishing techniques that should be employed in the event of such a fire incident.
