People must act faster to save lives in a fire emergency, and fire extinguishers are important tools to stop fires. However, they only work well if people use the right one for the type of fire. To help with this, this device has a colour that shows what’s inside and what kind of fire it can put out. Knowing these fire extinguisher colours code helps to stay safe and avoid making the fire worse.
With that in mind, this article will explain the different fire extinguisher colours. It explains what the colour means and what's inside of it. By learning this, people can pick the right one during a fire. In other words, knowing this information helps you respond better during a fire. Let's start reading!
Overview of UK fire extinguisher colours coding
In 1997, the UK approved the BS EN3 standard for fire extinguisher colours. This rule states that at least 95% of an extinguisher's body must be red. The ban that covers 5–10% of the surface indicates the type of extinguishing agent. Previously, extinguishers were coloured based on their contents. The purpose of this change is to make visibility better in smoke-filled environments and standardise identification across Europe.
The new colour-coding system allows quick recognition of fire extinguishers when emergencies come. Each coloured band represents a specific agent. For instance, red for water and cream for foam. This regulation ensures proper use. At the same time, it lowers the risk of using the wrong tools and follows the safety regulations.
Why choose the right fire extinguisher colours?
Choosing the right fire extinguisher colours is crucial because each colour represents a specific type for certain fire classes. For safety reasons, this colour system helps people pick the right one in emergencies. It also makes sure that everyone follows fire safety rules. However, using the wrong one can be dangerous. Here are the reasons why choosing the right colour is important:
- Risks of misuse: Picking the wrong fire extinguisher colours can be dangerous. To illustrate, choosing one that contains water on an electrical fire may cause bigger problems. Therefore, using the correct colour for a specific fire is crucial.
- Training and familiarity: Regular training helps people quickly spot and use the right extinguisher. Training also teaches about different fire types and how to handle each one safely.
Classes of fires
Fires are grouped into some categories based on what is burning. In the UK, there are six classes. Each class needs a specific type of fire extinguisher colours. Using the wrong tool can be dangerous and make the fire bigger. Therefore, it's crucial to know the different types of fires and have the right tools. Here are the explanations of fire types:
- Class A: Things like wood, paper, and textiles can start fires. To put out these, use a red, cream, or yellow fire extinguisher colour.
- Class B: This type is caused by flammable liquids like paint, petrol, or alcohol. Use a foam fire extinguisher with a cream label to put out these flames.
- Class C: This type involves flammable gases like propane and butane. To put out these fires, use dry powder in the blue fire extinguisher colours.
- Class D: These fires affect metals that can catch fire, such as magnesium, aluminium, lithium, sodium, and potassium. To put this fire out, use a dry powder fire extinguisher with a blue label.
- Class F: These fires involve cooking oils and fats. For instance, vegetables, sunflowers, or olive oil. Use a wet chemical fire extinguisher to put out those fires.
- Electrical fires: Electrical fires can start from broken wiring, overloaded circuits, or broken equipment. If there's an electrical fire, don't use water. Instead, use a blue fire extinguisher colours.
Types of fire extinguishers based on colour
Fire extinguishers help protect people and property during a fire. However, not all tools work the same way. Each type fights a specific kind of fire. To make choosing easier, manufacturers mark those devices with different colours. As a result, fire extinguisher colours guides help users pick the right one fast in an emergency.
After discussing why the right fire extinguisher colour is important, let's look at the different types of this device. We've learned that using the right colour can stop a fire, while using the wrong one can make it worse. Each colour shows which type of fire the extinguisher can put out. Here are the details:
Red – water
The red label on the fire extinguisher colours contains water. In fact, water can put out fires on solid things like wood, paper, and cloth. It works by cooling the burning material to stop the fire. However, do not use it on electrical fires or fires with flammable liquids. Water can carry electricity and spread burnable liquids. As a result, the fire can be more dangerous.
Cream – foam
The cream label on the fire extinguisher represents foam. This means, it contains foam inside of it. Foam can put out fires on solids like wood and paper. Besides, it can handle flammable liquids like petrol and paint. They cover the fire with foam, which cools it and cuts off the oxygen.
Blue – dry powder
The blue fire extinguisher colours contains dry powder. People use this to put out fires from solid materials like wood and paper. Aside from that, it stops fire from burnable liquids like petrol. On the other hand, it turns off gases and electrical equipment. However, avoid using them in small spaces since the powder can make it hard to see and breathe.
Black – carbon dioxide (CO₂)
The black label contains carbon dioxide (CO₂). This fire extinguisher is perfect for electrical fires and fires involving flammable liquids. It works by removing oxygen, which puts out the fire. This device doesn't leave any residue, so it’s good for areas with electrical tools. However, it doesn't cool the fire better, so the fire might start again if there's still heat.
Yellow – wet chemical
The fire extinguisher colours for wet chemical types are yellow. This tool is good for kitchen fires from cooking oils and fats. They spray a fine mist that cools the hot oil. This vapour reacts and forms a soapy layer, which stops the fire and prevents it from starting again. Wet chemical extinguishers can also be used on fires involving wood and paper.
Legal and Safety Compliance
The Regulatory Reform (Fire Safety) Order 2005 states that all non-domestic buildings in the UK must have a fire safety system. These buildings include offices, schools, and shops. They must have a proper fire extinguisher colours to identify the fire type. The reason is to protect both employees and visitors. Typically, the places have a "responsible person", who is the employer or building manager. They must make sure safety tools are working in the right way.
According to fire safety regulations, fire extinguishers must receive regular maintenance. A competent person must service them at least once a year. For instance, examining the extinguisher's weight, pressure, and condition. On the other hand, it checked for damage or tampering. The person in charge must do a visual check once a month.
In addition to that, it is important to record all fire extinguisher checks and services. This documentation must include details about the fire extinguisher colours coding. These should also show the date, the technician’s name, and the work. Good documentation proves legal compliance and helps with safety audits and insurance claims.
Conclusion
In conclusion, the fire extinguisher colours coding systems are important for the UK's building safety. It makes the extinguisher colours similar to the materials inside. This helps people quickly find the right device during a fire. In addition to that, the system follows legal fire safety rules. Knowing this system is key for fire safety in workplaces and public buildings.
