As small as 1 Bubble at a time to making millions of Bubbles with a Fire Engine, making Foam is simple. Think about the child playing with a bottle of bubbles.
The bottle contains W + Conc (Solution).
The ring sets up a film of the Solution and forms the size of the Bubble and acts as the agitator (A).
The child merely blows air (A) on the solution coated ring and viola!!! W + Con (=Sol) + A + A = A Foam Bubble (Foam is Bubbles and Bubbles is Water)
It’s that simple.
Now, let’s make foam on a larger scale.
W – Turn on the Water (See Water Pumps Below)
Conc – Turn on the Concentrate
We just made Foam (Foam is Bubbles and Bubbles is Water)
Another method for making Foam is using a PW Extinguisher charged with Solution (W + C) and incorporating an aspirating nozzle (A + A) to create a Finished Foam. {Add Photo}
W – Water Pump
W + Conc (=Sol) + A + A = Foam (Foam is Bubbles and Bubbles is Water)
The water pump. Even though water is 1 of 4 of the ingredients to making Foam, it is not the intent of this web site to teach Firefighters how to operate water pumps. All Fire Engines have water pumps. Pumps can come in many sizes, capacities, brands, etc. Pumps can be powered in a number of ways. There is no special size or type of pump required to make Foam. Apparatus operators must be familiar with the rig and understand the fire pump according to the manufacturer’s design and documentation, coupled with the individual Fire Departments operational policies and procedures.
Suffice it to say that the fire pump must be operating to make FOAM – W.
