Protecting Electrical Panels from Fire: The Power of Clean Agents

Definition and Characteristics of Class C Fires:


  • Class C fires involve energized electrical equipment as the source of fuel. This differs from Class A fires (ordinary combustibles) and Class B fires (flammable liquids).

  • In Class C fires, the electrical current itself sustains the combustion process.

  • These fires can be particularly dangerous because they can reignite if the power source is not shut off.

Common Causes of Class C Electrical Panel Fires:


  • Overloading: When a circuit is overloaded, it draws more current than it is designed to handle. This can cause overheating of wires and components within the panel, eventually leading to ignition.

  • Loose Connections: Over time, connections within the panel can loosen or corrode. This creates resistance, which translates to heat generation. If left unchecked, excessive heat can cause sparks or ignite surrounding materials.

  • Arcing Faults: Arcing faults occur when electricity jumps between unintended paths within the panel. This arcing creates sparks and intense heat, potentially igniting nearby components. Arcing faults can be caused by loose connections, damaged insulation, or moisture intrusion.

  • Manufacturing Defects: In rare instances, electrical panels may have inherent manufacturing defects that can lead to overheating or electrical breakdowns, triggering fires.

Potential Consequences of Class C Electrical Panel Fires:


  • Electrical panel fires can spread rapidly if not contained quickly. They can damage critical electrical infrastructure and disrupt building operations.

  • The intense heat generated by the fire can also damage surrounding equipment and building materials.

  • Smoke and fumes from burning electrical components can be toxic and pose health risks to occupants.

By understanding the specific nature and causes of Class C electrical panel fires, we can appreciate the importance of implementing targeted fire suppression strategies like clean agent micro-suppression systems.


The Clean Agent Micro-Suppression Advantage

Targeted and Rapid Fire Suppression:


  • Unlike water sprinklers which flood an entire area, clean agent micro-suppression systems employ a targeted discharge mechanism. This allows for the precise delivery of the extinguishing agent directly within the confines of the electrical panel.

  • Clean agents, typically gaseous compounds, act swiftly upon release. They disrupt the chemical reaction that sustains combustion within the fire, extinguishing flames within seconds. This rapid response minimizes damage to electrical components and prevents the fire from spreading.

Non-Conductive and Non-Corrosive Properties:


  • One of the biggest advantages of clean agents for Class C fires is their non-conductive nature. Unlike water, which conducts electricity, clean agents are electrically insulating. This eliminates the risk of electrical shorts and potential personnel hazards during discharge.

  • Additionally, clean agents are non-corrosive. This is crucial for protecting sensitive electrical components within the panel from water damage, which can lead to further malfunctions and even short circuits after the fire is extinguished.

Environmentally Friendly and Safe Discharge:


  • Newer clean agents boast low Ozone Depletion Potential (ODP) and Global Warming Potential (GWP). This makes them an environmentally responsible choice compared to some traditional fire suppression methods that can contribute to environmental damage.

  • Many clean agents are non-toxic and pose minimal health risks to personnel when deployed at recommended concentrations. This allows for safe and rapid evacuation during a fire event without the concerns associated with some traditional extinguishing agents.

Benefits of FIRESCI Micro-Suppression Systems:


  • The compact size of our micro-suppression systems makes them ideal for installation within electrical panels, which often have limited space.

  • Our systems are designed for automatic activation upon detection of heat or smoke within the panel, ensuring a quick response to fire emergencies.

  • FIRESCI systems require minimal maintenance compared to some traditional methods, reducing ongoing costs.

  • Advanced Detection Technology: FIRESCI systems go beyond basic heat detection. We can incorporate sophisticated multi-sensor technology that combines heat, smoke, and even rapid pressure changes to identify fire signatures with exceptional accuracy. This multi-pronged approach minimizes the risk of false alarms while ensuring the fastest possible response to a genuine fire event.

  • Early Detection with Active Smoke Aspiration:  FIRESCI offers an integrated active smoke aspiration system as an optional feature. This advanced technology continuously draws air samples from within the electrical panel, allowing for the earliest possible detection of smoke and fire signatures. This proactive approach can prevent fires from escalating, minimizing potential damage and downtime.
