Where firefighters come to talk training

Do you know how to fill the can?  We all know the can is a valuable piece of equipment on the truck.  The can can be used on small fires to extinguish them before the engine gets the line stretched.  It can also be used to protect the search by helping keep fire in the room of origin.


But in order to fully tap into its potential the can needs to be filled properly.

Do you know how long a properly filled 2.5 gallon can last? About 50 seconds

What about the initial stream reach? About 50 feet

How many PSI of air is in a properly filled can?

How much does it weigh? Do you know what a properly filled, under filled, and over filled can feels like just by pulling it off the rig?

Below are two videos. The first is an overfilled can. Its so overfilled that the pressure was 35 psi.  The second video is a properly filled can with a pressure of around 100. Notice any difference? Notice the stream quality, the reach, the penetration of the properly filled can.

So how do you fill it properly every time? I like to measure it.  1/2 gallon milk jugs or a spare DEF container is perfect. DEF jugs are 2.5 gallons.

If you are completely at a loss, the fill tube, that thing that you normally use to see if its wet at the bottom as you use trial and error trying to see if there is enough water in it, is made for filling the can.  When you pour water into the can, when it is at 2.5 gallons, water will over flow through the fill tube.  Don’t worry, the cans not full, but for some reason physics makes this work. Don’t ask me how, I’m not a scientist.  

As far as weight, a full pump can weighs approximately 28 lbs.

The best way to know for sure.  Every time you fill it up, measure the pressure with a tire gauge. You’re looking for that 100 psi. Hold it to get use to feeling what a properly filled can feels like.  And whatever day is your weekly apparatus day, after you check the tire pressure on the rig, swing back to the can and check the pressure on it too. If it ain’t 100 psi, fix it.

Also, before you charge it with air, put some foam or dish soap in there. 1/4 cup of foam or dish soap would give you an approximate mixture of 0.5%.
