best advice is to try to conserve it, dont just spray. When you use dry chem, dont inhale the powder, its not fun. I dont know why he gave you one that needs charging, its useless and you might as well buy new. i also suggest trying to find co2 extinguishers as a backup and for electrical type fires. They work great for those as long as you cut the power first. That powder gets everywhere and is a bitch to clean up. I hvant really seen co2 extinguishers for sale commerically but i havnt really looked, im going to try and see. Might pick up a 10 pounder too. Ive seen some pictures of burnt out blazers and i dont want mine to be one, she backfires a decent ammount too because the holly she has is way too big.
Edit: also i forgot to add. If you have old ones or whatever. it is good to set up a fire and practice just as scotto said. fire extinguishers become far more effective in the hands of someone who knows what their doing. Dry chem is pretty easy to use, the powder just gets everywhere and smothers the fire. Water cans are harder than people think to use effectivley and co2 extinguishers are also a little more difficult to use effectivly. Most people dont get close enough for it to work. CO2 you need to be pretty close. As part of my training i had the pleasure of using a co2 extinguisher agiast a stack of burning pallets. Most people didnt get close enough to even affect the fire, i got close enough to starting putting it out but had a nice sunburn after. That was a poor application for CO2, plus it was a windy day. Anyhoo its a good idea to practice and try to carry both.
i dont think water cans are worth carrying because most likley whats burning is a b or c fire.
