Find Out About Fire Extinguisher Ratings

Fire extinguisher designed to demonstrate the kind of ratings they should be used on fires, and give an indication of how effective they will be. Each rating fire expressed as a series of numbers and letters that indicate the class fire can be used in a size suitable for fire.

Different types of fires are classified by different letters, and the ranking fire extinguishers may indicate some letters because they can be used on more than one type of fire. In terms of the size of the fire service can be used on fires, the number gave an indication of this, and in General, the larger the number, the bigger the fire extinguisher that can handle.

Numerical ranking part is directly related to firefighting conducted tests to measure their effectiveness. Wooden box test is a test used to measure how big the fire extinguisher can handle. Ranking fire extinguisher 13 A, for example, showed that firemen were able to extinguish the fire of 1.3 m. The number on the fire rating is highly accurate indication of what firefighting can be overcome.

As another example of a numeric value, a test to measure the effectiveness of fire for use on flammable liquids refers to the approximate area of fire in square feet that can be put out. Certain tests vary with different types of fire, but the basic system to accurately measure the effectiveness of the same Brigade.

It would seem obvious, to think that the number on a fire extinguisher will increase with the size of the fire service. This is generally true, but the size is not the only factor that effects the rating number in the fire department. With water fire extinguisher, additives are often blended with water to increase their effectiveness, therefore you can have two fire extinguishers that are the same size, but that have different numerical ranking, because it's wrong one is more effective than others.

Fire classification-UK and us differences

As already mentioned, the letters used in the ranking refers to the fire classes that they can be safely used on fire engines. Therefore, we need to see this fire classification first, before looking at the actual ranking Fire Department for various types of fire engines.

Classification for the United Kingdom and the United States are similar, but there are some differences, so I will be a good show. Europe and Australasia will also use the same classification system as the United Kingdom. The following are the main classification of fires, with the U.S. class in brackets:

Class A fires (also A-class in the US)

There is a fire involving solid materials such as wood, cloth, paper, card, etc.

Class B fires (also class B in the US)

Class B fires involve flammable liquids, including kerosene, gasoline, paint, oil, diesel, etc.

Class C fires (coming under class B in the US)

A separate classification except in the U.S., this category is for gas, including Butane, methane, etc.

Class D fires (also class D in the US)

D is the classification for flammable metals or alloys, such as potassium, magnesium or titanium.

Electric fire (class C in the US)

Electrical fires are sometimes known as the E-class in the United Kingdom, but this is a mistake because there is no separate classifications for electrical fires in the United Kingdom.

Fire class F (grade K in the US)

Specifically related to the fires that involve frying fat (fats and oils).

Fire rating:

The following information shows the class covered by the different types of firefighting:

The main fire extinguisher ratings indicated refer to the United Kingdom, with the United States ranking in parentheses.

Water fire extinguisher:

Fire classes: A

(A-class in the US)

Carbon dioxide fire extinguishers:

Electrical fires: fire classes, A, B and C

(A, B and C in the US)

Dry powder fire extinguisher:

Fire classes: A, B, C and electrical fires

(A, B and C in the US)

Wet chemical fire extinguisher:

Fire classes: F,

(A and K in the US)

Foam fire extinguisher:

Fire classes: A and B

(A and B in the US)

Fire Department Report-conclusion

Understanding classes of fire and fire rating is very important to use the correct kind of sure fire extinguisher in your workplace. This can be very dangerous to use the wrong type of fire extinguisher on several fires, one of the most obvious example being the use of water on an electrical fire. For this reason the proper staff training is important for any staff who asked to use firefighting equipment.
