Every time i saw the fire-extinguisher placed next to me in my office, was wondering what exactly does the 'Class of fire' mentioned on fire-extinguishers mean? Well, this is what it is:
Class "A" extinguishers are used on fires that involve wood, paper, fabric and similar materials.
Class "B" extinguishers are used on fires that involve gasoline, oil and certain chemical fires.
Class "C" extinguishers are used on electrical fires.
Class "D" extinguishers are used on fires that involve exotic flammable metals,like Magnesium, Sodium, And Potassium.

...and i also want to mention one more thing i read today. I had no much work today, so was browsing on wierd topics like Body-Mass-Index, Religion, WCDMA, Kernel Programming, Cartoon by RK Lakshman and Sridhar etc. Almost all religions believe that the whole universe is goverened by an omnipotent. Jainism does not include a belief in an omnipotent supreme being or creator, but says that the whole cosmos is self-created, self ruled, self regulated and self-administered, according to the mighty and eternal cosmic law. Good!

Anyways enjoy this:  by Sridhar
