What Are Class C Fires? A Detailed Overview

Fire has different types, and each one requires a different approach to be tackled. One such type is class C fire, which involves electric equipment, wiring and appliances. These fires are fueled by electricity, making them potentially dangerous if handled in the wrong way.

Class C fires can occur in homes, workplaces, and industrial settings due to faulty wiring or overloaded outlets. Understanding what is c class fire and how to prevent, tackle, and safely extinguish it is crucial to minimise risk and ensure safety in the surroundings.

What are Class C Fires?

Properly identifying a fire class helps firefighters and people choose the right fire extinguisher and adopt safety measures to handle the situation effectively.

Wondering class C fire is what type of fire? Energised electrical equipment, such as circuits, breakers, power chords, transformers or any electrical appliance, cause a class C fire. Since electricity is the fuel source, one cannot extinguish class C fire with water. In fact, water is a conductor of electricity and increases the risk of electrocution.

How To Prevent a Class C Fire?

It’s impossible to eliminate all risks of a class C fire, but there are several ways to reduce the likelihood of it.

• Inspect wiring regularly: Looking for frayed or damaged power cords and replacing them instantly can eliminate the risk of fire.
• Avoid overloading outlets: Do not plug too many devices into a single outlet, minimising the chance of overheating and sparks.
• Keep electrical areas clean: Dust around outlets or electrical panels can cause a fire.
• Checking for smells or sparks: If you notice a burning smell or see sparks from any appliance, unplug it immediately and get it checked by an electrician.
• Use certified electricians: Only professionals should install, maintain, and be responsible for repairing electrical systems. Do not try to do it yourself.

Regular inspections and proactive equipment replacements are key to fire safety. Ensure that all employees or household members know how to respond to an electrical fire and be ready for any emergency.

Tackling a Class C Fire

If you ever come across a class C fire, the first step is to turn off the main power source if it’s safe to do so. Cutting off the electricity stops the fire from growing. Once the power is off, the fire may then be treated with the right extinguisher, depending on the materials that are burning and the cause of the fire. 

Here are the different fire extinguishers and what are class c extinguishers used for:

• Dry chemical fire extinguishers: These have a blue label on them. The best choice for putting out an electrical fire is this, as it does not conduct electricity.
• A carbon dioxide extinguisher: A CO2 fire extinguisher removes oxygen and cools the fire without leaving any residue.

What not to do?

• Never use water or foam: Water conducts electricity and increases the risk of electrocution. Foam fire extinguishers or wet chemical fire extinguishers are also not suitable for Class C fires.
• Avoid direct contact with the electrical equipment: If a fire starts in an electrical panel, do not try to touch it or open it. It calls emergency services instead.
• Stand at a distance: Electrical fires can spread rapidly and may produce toxic fumes, so safety should always be prioritised.

Class C Fires - Characteristics And Challenges

Class C fires pose unique risks, especially when they occur in critical infrastructure like power grids, transformers and renewable energy sources. 

Transformer fires

Transformer fires and electrical transformers contain oil that can leak and cause fuel fires. These fires require suppression techniques to prevent environmental contamination and extensive damage.

Electric Power Grid

Electric power grid age and infrastructure, severe weather and high energy demands can lead to an electric fire within the power grid. These fires can disturb electricity supplies and require advanced fire separation strategies to prevent blackouts.

Lithium-ion Batteries and Solar Panels

Lithium-ion batteries can overheat and enter a state of thermal runaway, leading to uncontrollable fires and explosions. Fires involving lithium-ion batteries give out toxic fumes and are difficult to extinguish as they generate their own oxygen supply.

Even when disconnected from the main power supply, solar panels can continue generating electricity, posing a risk of electric shock and reignition. Fires in solar energy systems require specialised firefighting approaches.

Buy Extinguishers As Your Best Defence Against Class C Fires

Electrical fires are unpredictable and hazardous, but the right fire extinguisher can make all the difference between a minor incident and a major disaster. Investing in a class C-rated fire extinguisher ensures that you are prepared to handle electrical fire safely without the risk of electrocution or further damage.

With options like dry powder fire extinguishers, you can confidently protect your home office or industrial space from fire hazards. These extinguishers act by cutting off the fire fuel source and preventing it from spreading.

What are Class F Fires? Everything You Need To Know

Fires can be grouped into different classes. They are each defined by the type of fuel burned. Class F Fire is one of the most dangerous and complex fires to tackle. This type of fire involves cooking oils and fats which burn at extremely high temperatures. These fires require special handling and some special extinguishing methods to prevent further spread and damage.

Class F fires are a serious hazard. They generally take place in kitchens and food preparation areas. Knowing how they start, how to prevent them and how to extinguish them can save lives and property. By using the proper kitchen safety procedures, regular risk assessments and the right fire fighting equipment, the risk of class F fires can be minimised.

Understanding Class F fires is essential, especially for the ones working in kitchens, food preparation areas and catering businesses. In this guide, we will learn what is type F fire, how one can prevent them and the correct methods for extinguishing them.

What is Class F fire?

Class F fires occur when cooking oil catches fire. Unlike flammable liquids such as petrol, which have blue flash points, cooking oils require temperatures above 340°C to ignite. Due to these high temperatures, traditional fire extinguishers are not effective in putting out Class F fires and can make the situation worse. 

As discussed, class F fires are common in kitchens, restaurants, schools, hospitals, hotels, and catering facilities. They are often caused by negligence, such as

• Overheating oil in a deep fryer
• Leaving pans unattended while cooking
• Not cleaning oil and grease from cooking surfaces
• Allowing oil to build up over time

Since these fires involve hot oil, they burn fiercely and can quickly escalate if not handled correctly.

Preventing A Class F Fire

Prevention is better than cure, and when it comes to class F fires, careful kitchen management is the key to reducing risks. Here are some essential tips.

• Use controlled fryers: These devices automatically maintain a safe temperature, preventing oil from overheating.
• Monitor cooking closely: Never leave the frying pan or deep fat flyers unattended when in use
• Do not overfill the pan with oil: Keep oil levels below one-third of the pant to reduce the risk of spilling
• Clean oil and grease regularly: Residue buildup can ignite if exposed to heat
• Turn off heat sources after use: Open flames and hot surfaces can start fires if left on
• Train kitchen staff: All people should know the risks and safety measures associated with cooking oils and fats

Following these simple steps can minimise the chance of class F fires, making the working areas a safer environment for everyone.

How to Deal With a Class F Fire?

Class F fires burn at extreme temperatures, making them difficult to extinguish, unlike other fires. They cannot be put out with water, carbon dioxide or dry powder extinguishers. These methods can likely worsen the situation. Here are the Correct steps to handle a class F fire safely.

• Turn off the heat source: The first step is to turn off the heat source. This will help stop the fire from spreading further.
• Use a fire blanket for small class F fires: Blankets can be effective. Cover the flames completely to cut off the oxygen supply and extinguish the fire.
• Use a wet chemical fire extinguisher for larger fires: If you’re wondering– what is class F fire extinguisher? The only safe method of extinguishing a class F fire is with a wet chemical fire extinguisher. These wet chemical fire extinguishers contain potassium salt, which tends to cool the flames and form a foam layer over the burning oil, preventing reignition.
• Don’t use water: Throwing water on a class F fire can cause an explosion as the water evaporates instantly upon contact with the hotel, spreading burning oil droplets over a wider area. This can make the fire significant and increase the risk of injuries.
• Evacuate immediately and call the fire brigade: If the fire becomes uncontrollable, evacuate the area immediately and call emergency services. Do not take unnecessary risks.

How To Extinguish A Class F Fire?

To successfully put out a fire, one of its three elements must be removed: heat, oxygen or fuel. However, sometimes, due to the intense heat of class F fire,  cooling them below their flashpoint is challenging. 

The best method is to use a wet chemical fire extinguisher, which works by cooling the flames, monitoring the fire to cut off oxygen, and creating a protective barrier to prevent re-ignition. Other types of fire extinguishers, such as CO2, foam, or dry powder, are not suitable for class F fires and can be dangerous to use.

How to Avoid a Class F Fire?

For kitchen owners and managers in business, It is essential to take preventive measures to protect people and property from class F fires. Here are some key steps to follow.

• Conduct regular fire risk assessments to identify potential hazards.
• Install a wet chemical fire extinguisher in a commercial kitchen.
• Fit fire alarms and separation systems in high-risk areas.
• Ensure clear evacuation plans are in place and communicated to staff.
• Train employees on fire safety and proper handling of cooking oils.

Even with the best precautions, it is impossible to eliminate the risk of class F fires. However, maintaining safe kitchen practices and providing regular staff training can minimise the risk and improve overall fire safety.
