What is a danger to consider when attacking a Class C fire?

When responding to a Class C fire, one of the primary dangers is energized electrical equipment. Class C fires involve flammable gases and liquids as well as energized electrical equipment. In this context, any attempt to extinguish the fire without taking precautions can lead to severe hazards, such as electrical shock or electrocution.

When dealing with a Class C fire, it’s essential to ensure that the power source to the electrified equipment is de-energized before initiating any fire suppression efforts. Using water, which is a conductor of electricity, on an energized fire can further increase the risk of electrical shock for firefighters and can worsen the situation by potentially spreading the fire or causing more damage.

The other options, while they refer to legitimate hazards in firefighting, are not the primary focus when dealing explicitly with Class C fires. Flammable materials and structural instability may pose risks in various fire scenarios, but the immediate danger presented by energized equipment makes it paramount to prioritize electrical safety in these contexts.
