There are several categories of fire extinguishers. It depends on where the extinguisher is likely to be used and on what type of fire is to be expected. For example: a soda and water extinguisher is commonly used for general type fires. But, due to the risk of being electrocuted, a soda and water extinguisher would be dangerous to use round high voltage electrical equipment - so a carbon dioxide extinguisher would be used instead. On oil fires, a foam extinguisher would be best, as a soda water extinguisher would simply spread the area of the oil fire, and even increase the intensity of the flames, while the foam would smother the flames, cutting off the oxygen to feed the fire.
