Why not??
If safety is your concern, then it may interest you to know that all stored pressure type fire extinguishers have their Working Pressure and
Test Pressure ratings printed on them...
From the
pic in the article referred to, it appears that a 9l. water type has been used..
The one that I have (chubb) has a WP of 700 KPa, & a TP of 2.0 MPa..
I believe that 1000 KPa (or 1 MPa) = (approx.) 145 PSI, therefore, from the above figures, it will have been tested to 290 PSI...
The several dry powder types that I have (1.0 kg, & 2.5 kg) have TP ratings considerably higher... Up to 3.3 MPa or 478.5 PSI...
I agree that the truck tanks are the way to go (if you can find one the right size), but from a safety point of view, I can see little if any risk using a fire ext. canister provided of course, that a suitable relief valve is fitted.
