What is a hazard that must be considered when attacking a Class C fire?

When addressing a Class C fire, which involves energized electrical equipment, the primary hazard that must be considered is electricity. Class C fires can occur in situations where live electrical circuits are present, and using the wrong extinguishing agent can lead to electrocution or further ignition. It is essential for firefighters to ensure that the power source is turned off before attempting to extinguish the fire or to use an agent that does not conduct electricity, such as a dry chemical fire extinguisher specifically rated for Class C fires.

Electricity poses unique risks because water is a common extinguishing agent but is conductive and can create dangerous conditions if applied to electrically charged materials. Understanding this hazard is crucial for ensuring the safety of firefighting personnel and mitigating the potential for injury or worse outcomes while tackling a Class C fire.
