How do Carbon Monoxide Detectors Work

When it comes to fire safety preparations, no list is complete without fire extinguishers. You know that this easy-to-use installment can immediately put out the flames in no time, with a simple pull, aim, and squeeze method. However, what most people do not realize is that fire extinguishers come in different types and classes, and depending on what type of fire these people are experiencing, one type of extinguisher might work better than the rest.

The Classes

Since fires can begin anywhere at any time, you have to be aware of what they are burning to effectively put them out. By doing so, you will be able to choose the correct fire extinguisher for the given situation – enabling you to eradicate the flames as soon as possible. The class of the fire extinguisher can be seen on its surface, and can be labeled as such:

Class A: Are for solids like paper, wood, plastic, and the like.

Class B: Is for flammable liquids such as paraffin, petrol, oil, etc.

Class C: Handles situations that involve flammable gasses like propane, butane, methane, and others.

Class D: Are for metals like aluminum, magnesium, titanium, and the rest.

Class E: Is reserved for fires that involve electrical apparatuses.

Class F: For cooking oil, fat, and the like.

The Types of Fire Extinguishers

It is scientifically proven that some substances just do not mix – take water and oil for example. This fact can also be said about fire extinguishers because sometimes, the bases of their materials may interact with the flames and can make the situation even worse. So if you decide to purchase this installment into your building, please be mindful of where you are placing it.

Water Fire Extinguishers: Cheapest and most widely used. Can effectively put out fires that are in Class A and are not suitable for Class B or where electricity is involved.

Foam Fire Extinguishers: It is more expensive than water, but is more versatile. It can be used for both Class A and B fires, but it is not advisable to be used in situations that involve electrical apparatuses.

Dry Powder Fire Extinguishers: Also known as, the “multi-purpose” fire extinguisher, this type can be used on Class A, B, and C fires. However, you have to be aware that when you are using this in situations that involve gasses, you need to isolate the gas supply first before you extinguish the flames.

CO2 Fire Extinguishers: This is an ideal fire extinguisher for fires that are surrounded by electrical apparatuses. However, if you are not using this correctly, it could re-ignite the flames.
