stored pressure water extinguishers
I tried searching the forums for related threads, but didn't have any luck. If anyone can find this previously asked question, please let me know where the thread is.
How many of you carry stored pressure water extinguishers on your trucks?
Once used, can you service them yourself (i.e. fill them back up and re-charged them) or do you need to take them to a specialized shop to have this done?
Can they be re-charged with just air? Someone recently told me it was nitrogen, which I kinda doubt.
Anyone ever build or purchase a kit to re-charge a can off of a SCBA bottle?
Can you simply put AFFF or another foam agent in the can to have a simple CAFS, or is there more to it than this?
Thanks for your thoughts.
