One of the most important things about designing a health and safety plan is instructing your employees or at least your key management staff on the use and the classifications of fire extinguishers. Many people know about extinguishers but have no idea which ones work for the type of fire they may have. When your company is giving instruction on the classifications of fire extinguishers, you will need to start by explaining how important it is to use the right equipment, on the proper type of fire. The reason for this is that the use of the wrong extinguisher can create even more problems that may lead to injuries to the person using the extinguisher and the people in the area.

    Usually the classifications of the fire extinguisher are comprised of letters which tell you what type of fire it is best used for and number showing the size of the fire that the extinguisher can handle. Some s extinguishers may be used for several types of fires, which mean it will have several different letters in its classification.

    In order to come up with the number, many tests were conducted by setting fires and putting them out using the extinguisher. Therefore an extinguisher that has a number of 12 can extinguish 1.2m of fire. The higher the number, the larger the fire you can use this piece of equipment on.

    Another important thing that should be a part of your health and safety knows what types of fires can be extinguished by the type of extinguisher you have. The A classification refers to extinguishers that deal with regular everyday materials like paper, wood, textiles and cardboard. With the B classification, you can put out oil and petrol fires. The C classification allows you to extinguish gases and propane. Metal fires use the D classification. The F classification refers to fires made by deep fat burning. In the UK there is no set classification for electrical fires, some think it would be the E classification, however this is not true. The way the UK looks at this classification is that once you take away the power supply it would easily classify as one of the other classifications, so they did not give electrical fires a classification. However it is important to remember that if the extinguisher is a water extinguisher, and you put it on an electrical fire you may find yourself electrocuted.

    Knowing the different classifications of fire extinguishers are a good way to ensure your health and safety should you have to deal with a fire. If you don't know the different classifications it is best that you do not try putting the fire out.

    設(shè)計(jì)一個(gè)健康和安全的計(jì)劃最重要的事情之一是指導(dǎo)你的雇員或重要管理者對(duì)滅火器進(jìn)行使用和分類(lèi)。很多人對(duì)滅火器略有所知，但他們并不知道用哪種滅火器對(duì)付哪種火焰。當(dāng)你的公司正在進(jìn)行滅火器種類(lèi)講解時(shí)，你首先需要知道正確使用滅火器設(shè)備以及判斷火焰類(lèi)別是何等重要。因?yàn)殄e(cuò)誤的使用方法會(huì)對(duì)手持滅火器的人以及周?chē)�的人們�(cè)斐蓚�害�?/p>

    通常滅火器分類(lèi)方法是由字母和數(shù)字組成。字母表示該類(lèi)滅火器用于對(duì)付哪種火源，而數(shù)字表示滅火器可以處理的火勢(shì)大小。有些滅火器可以用于多個(gè)類(lèi)型的火源，因此上面標(biāo)識(shí)的分類(lèi)含有多個(gè)不同的字母。

    為了精確地定義滅火器上的數(shù)字級(jí)別，人們通過(guò)點(diǎn)火和用滅火器滅火來(lái)進(jìn)行多次實(shí)驗(yàn)。標(biāo)識(shí)為數(shù)字12的滅火器可以熄滅1.2米高的火焰。數(shù)字越高，可以控制的火勢(shì)越大。

    另一個(gè)關(guān)系到你的健康和安全的重要的事情是，你得知道你可以用你手里的滅火器撲滅哪種火焰。A類(lèi)滅火器可以撲滅日常材料引起的火災(zāi)，例如紙張，木頭，織物，硬紙板。B類(lèi)可以撲滅汽油和石油引起的大火。C類(lèi)則用戶撲滅煤氣、甲烷引起的火災(zāi)。撲滅金屬燃燒的大火要用D類(lèi)。F類(lèi)滅火器用于厚脂肪燃燒引起的大火。在英國(guó)，沒(méi)有電器火災(zāi)滅火器的分類(lèi)，一些人把它叫做E類(lèi)，然而這是不正確的。一旦將電源切斷，這類(lèi)滅火很容易就被歸為其它的類(lèi)別，所以無(wú)法對(duì)這一類(lèi)滅火器進(jìn)行分類(lèi)。但重要的是你得記住，如果你用水管類(lèi)滅火器來(lái)對(duì)付電器引起的火災(zāi)，那你肯定會(huì)觸電。

    了解不同種類(lèi)的滅火器，能使你在不得不對(duì)付火災(zāi)時(shí)很好地保證你的健康和安全。如果你不了解這些滅火器的差別，你最好別去嘗試滅火。
