It’s important to understand fire classifications for fire safety purposes, especially in workplaces where electrical, chemical, or flammable liquid fires could take place. Multiple types of fires need distinct strategies and specialized types of extinguishers.
So let’s talk about class C fires and the extinguisher used to control this type of fire. Class C fires are also called electrical fires. Knowing the characteristics of Class C fires, as well as how to avoid and control them, is critical for maintaining the security of homes as well as businesses. Class C fire extinguishers are necessary in areas with extensive electrical equipment use.
What Is a Class C Fire Extinguisher?
A Class C fire extinguisher is a one-of-a-kind piece of safety gear made to put out a fire that involves energized electrical equipment.
Class C fire extinguishers apply non-conductive extinguishing chemicals, like dry chemical powders. Such substances can extinguish a fire without causing it to spread or harm the person using the extinguisher by shocking them.
What Are Class C Fire Extinguishers Used For?
Being aware of class C fires is necessary before learning about class C fire extinguisher uses. A class C fire occurs when an energized electrical source causes the fire. Incorrect wiring, a short circuit, damaged power cords, stuffed outlets, overheated or overcharged devices, etc., can all cause class C fires.
So, a Class C fire extinguisher may be utilized to put out a fire started by an energized electrical appliance. The fire no longer meets the criteria for being categorized as a class C fire and falls into one of the other classes of fires if the power source has been removed. Removing the power source isn’t always possible, though.
Types of Class C Fire Extinguishers
While all Class C fire extinguishers serve the same primary goal, they are classified into different types. Here are the most popular choices:
- ABC Dry Chemical
- Carbon Dioxide (CO2)
- Halon extinguishing agent
- Clean Agent Class C fire extinguishers
- Water Mist extinguisher
Composition: What is in a Class C Fire Extinguisher?
Class C fire extinguishers commonly use non-conductive chemicals such as carbon dioxide (CO2) or dry chemical powders that remove oxygen and smother the flames. These Class C fire extinguishers may include potassium bicarbonate, monoammonium phosphate, or potassium chloride. They all are effective for extinguishing Class C fires.
Class C Fire Extinguisher Pictogram and Labels
The main intent of these labels and signs is to immediately indicate the types of fires that a specific extinguisher can be utilized on. Since fires may originate from a variety of sources including electrical equipment, flammable substances, and sometimes cooking oils, it is critical to match the fire type with the right fire extinguisher.
When an improper kind is used, such as when a water-based extinguisher is tried on an electrical fire, it might cause electrocution or worsen the fire.
The symbol of class C is a blue circle with the word C within it. The pictogram frequently has an electrical socket or an electric bolt to show that it is suitable for use in electrical fires. With a fire in the background, the latest pictogram depicts an electrical wire and outlet. The letter C in a blue circle was the previous symbol.
Do Class C Fire Extinguishers Come in Bulk Containers?
Class C extinguishing agents are rarely available in bulk containers, such as containers, for manual application because doing so might not satisfy the unique needs of Class C fires and could present safety hazards.
Instead of being packed in large quantities, these extinguishers are usually available for sale as individual units. The use of portable or fixed systems guarantees accuracy and regulated usage, which is important in effectively extinguishing electrical fires.
On the other hand, suppliers and manufacturers may provide bulk purchasing options for companies or organizations that require several units at lower prices. These must be purchased from reliable suppliers in order to ensure durability and adherence to safety regulations.
Electrical Fire Extinguisher Class C: How It Works
Class C fire extinguishers use chemicals that can separate the three parts of a fire: oxygen, heat, and fuel. Class C fire extinguishers might include carbon dioxide, which suppresses a fire by removing oxygen and reduces heat by cold discharge. They can additionally contain dry chemicals to break down the parts that sustain a fire: oxygen, heat, and fuel.
Maintenance and Safety Tips
Although utilizing a Class C fire extinguisher is comparable to applying any other kind of fire extinguisher, there are some special requirements and safety precautions that must be followed. Here are some of the most crucial yet sometimes overlooked tips for operating a Class C fire extinguisher:
1. Make sure that your Class C fire extinguisher is free of leaks, damage, or low pressure once a month.
2. Double-check that the tamper seal and safety pin are properly installed.
3. Inspect the nozzle to make sure it’s not blocked.
4. Recharge the extinguisher after each usage, even though only a small amount was used.
5. Schedule a professional inspection every year.
6. Train employees on how to use a fire extinguisher carefully with the PASS technique:
- Pull out the pin.
- Aim the fire’s base.
- Squeeze pressure on the handle.
- Sweep from side to side.
7. Conduct regular fire drills to keep prepared.
Conclusion
Class C fire extinguishers are an essential part of every fire prevention method since they are necessary for the secure and effective control of electrical fires. You can protect yourself and be ready to act fast in an emergency by being aware of their types, functions, and right maintenance. Always inspect and maintain your fire extinguishers regularly and train everyone on their proper use to keep your home or workplace protected.
