What are the differences of Water vs Water Plus vs Water Mist fire extinguishers? Which is best and what is the best for certain situations?

Water Plus extinguishers are an easy upgrade on the regular water extinguishers. They feature a wetting agent which allows them to achieve a greater fire rating. This helps to meet regulations on minimum fire ratings per floor or room of a building. This extinguisher still only features an A fire rating, meaning it can only extinguish Class A fires.

This means they are capable of extinguishing Class A and Class F fires. Class F fires are fires involving deep fat frying and spillages of flammable oils near heat sources.

The Water Plus and the Water Mist are both upgrades from the standard Water extinguisher in their own ways. The Water Plus offers an increased A fire rating and the Water Mist offers an AF fire rating over the basic A fire rating of the other two extinguishers.
