Why is the fire extinguisher red?

Question

In biology

Answer

They are not always red. 
Red is water used on non electrical and definitely not chip pan fires
Black is basically dry ice and can be used on any fire
Then you have cream
Cream is a foam and I don't know what it's specifically for. I think it's used on combustibles like petrol as it smothers the flame. Again not on a chip pan though

Answer

Biology has nothing to do with it.

Two and two are four, and four and four are eight, and four plus eight make twelve, and there are twelve inches in a foot, and one foot is a ruler, and Queen Elizabeth was a ruler, and Queen Elizabeth was also a ship, and the ship sailed the seas, and there were fish in the seas, and fish have fins, and the Finns fought the Russians, and the Russians are red, and fire trucks are always &ldquo;Russian" around, so that's why fire trucks are red! Fire extinguishers too!

Answer

The 'old' British Standard for fire extinguishers (BS 5423) stipulated that the entire body of the extinguisher be colour coded to indicate the contents as follows: Red-Water, Cream-Foam, Blue-Powder and Black-CO2.
