Hello, my name is Eric and this is my home improvement and energy blog. I am very worried about the impact of climate change on our planet so I have recently taken steps to reduce my carbon footprint while carrying out home improvements. Although I am concerned about climate change, I do not know a lot about green energy solutions so I contacted an energy and environmental consultant. The consultant visited my property and recommended I installed solar panels on my roof. Since I did this, I have seen my energy bills fall and I am so happy to be saving money and the environment.

A fire extinguisher is perhaps the most common fire safety equipment utilized in homes and business premises. Most individuals think that any fire can get put off by just any extinguisher. However, just like there are different kinds/classes of fire that can pose a threat to an establishment, there are specific types of fire extinguishers for every sort of combustion.
Hence, when buying fire safety equipment and learning how to use the extinguishers, it is essential also to learn the numerous classes of fire as well as the appropriate ways to handle them.
Carbon Dioxide (CO2)
Probably the most common type of extinguisher, it is suitable for only B and C class fires. The extinguisher puts out a fire by limiting the availability of oxygen and heat by discharging a robust and cold stream of compressed CO2 gas.
Chemical Extinguishers
There are two types of chemical extinguishers—namely, wet and dry chemical extinguishers.
Wet chemical. It discharges a chemical that provides a barrier between the burning substances; for example, a grease or fuel flame would be covered so that access to oxygen gets cut off and the fire cannot reignite.
It is commonly used to tackle Class K fires, but sometimes it can also handle a Class A fire.
Dry chemical. These extinguishers release a chemical compound which eases the chemical reaction in combustion. There are two types of dry chemical extinguishers—namely, multi-purpose and regular.
The regular version is only applicable for Classes B & C fires. However, the multi-purpose version can get utilized in Classes A, B & C.
Water and Foam
For these extinguishers, the water takes away the heat aspect of a fire while the foam provides a barrier between oxygen and the flaming material. It is essential to understand that this type of fire extinguisher gets designated for Class A fires only.
If used in Class B fires where there are flammable liquids or gasses, the water and foam discharge could facilitate the spread of the fire. On Class C fire involving electric equipment, the water discharged could lead to the user getting electrocuted.
Water Mist Extinguisher
This type of extinguisher gushes out water via a small opening, causing the water come out as mist. The mist then puts out a fire by taking away the heat element. The mist extinguisher is mainly applicable for Class A fires, but if there is no alternative extinguisher, you can use it for a Class C fire.
