What to do with empty fire extinguishers?

admin

I have about 25 that are about 15" tall and some that are larger.  Any ideas?  I thought about wind chimes.....

Reply:fill it with C4 explosives, stripped nuts, junk bolts and ball bearings.  Go to Kim-Jung-un's house, light the fuse, ring the door bell and run for it.
Reply:Switch the valves out, have em pessure checked and filled with NO2 and sell em. You can buy highflo valves from nos. Dont use medical grade valves!Nitrous bottles will bring good money

Reply:I gave a buddy one and he was going to use it as a fuel tank for a mini bike...
Reply:They can be refilled and recharged ya know. They are not a one shot deal, except the smaller ones may not be worth the effort, but the larger ones for sure. Just look up fire extinguishers in the yellow pages, there may be a company nearby that does them.
Reply:right about c4, we used small chunks to heat our coffer/c-rats, it burns nice, need caps to "BLOW" Mr. UN is a few bricks short of a full load.....

Reply:What we would do with them as a kid, take them apart drill a hole in the side and put in a valve stem from a car in there.  Fill it with water, air it up and go hose someone off.  Kinda fun to blast your friends with a CLEAN blast of water.     If you don't want to do that, then get them filled like previously stated.---No good deed goes unpunished---

Reply:I cut one open and use the bottom half for cutting fluid. I used the top for a funnel once. I think it was non reusable. Wind chimes sound good.
Reply:I decided to google.Recharging and Disposing of ExtinguishersDepending on the facilities in your community, you can often have expired fire extinguishers recharged for a low fee. Check your extinguisher to make sure that it can be recharged--some extinguishers are single use only--and then call the office number for your local fire department. If the fire department does not have the facilities to recharge your extinguisher, they will be able to direct you to a local business that can provide this service.If your extinguisher is a single use model, you must dispose of it properly. This means you cannot put it in your household trash or drop it in a local dumpster. The materials that fire extinguishers are made of, combined with the chemicals inside, qualify old extinguishers as hazardous waste. To dispose of an old or empty extinguisher, put in a call to your area Public Works department or sanitation services. They will be able to instruct you as to where to take your extinguisher or where and when you can place it for pickup by the department.
Reply:FYI most times the valves will screw out by hand or with the gentle persuasion of a rubber mallet against the handle in a loosening direction.
Reply:Check with your LWS for extinguisher services in your area.  One of the LWS here, actually has a division that does it in house.  Some extinguishers need to be hydrostated and that frequently rules out re-certs on lesser quality units once they reach that age.  Better quality units are worth re-certifying providing they have metal valves and the hose and nozzles are in serviceable condition.To drain off the pressure on an extinguisher, invert it and open the valve outside in an open area.  Aim it down wind and bleed off the gas until the gauge reads zero.  Then it is safe to remove the valve from the tank and dump the dry chemical into a container.  I put it in a plastic bag and tape the bag around the body of the tank so as to contain the dust.  I tap the tank with a mallet as the powder is emptying to break up any clumps.  Once the tank is empty twist the bag closed and tape off then remove the tank from the neck of the bag.  I have used the old tanks for wind chimes, fuel tanks for small gas equipment and even made a gear lube dispenser by replacing the nozzle with a hose and drilling and tapping the tank for a Schrader valve fitting.  I filled the cleaned tank with the desired amount of gear lube, replaced the valve body and pressurized the unit with shop air to about 50 PSI.  That was pretty much a one time use, on a gear box I had to rebuild on a grain leg on top of an elevator.  It was an awkward location to service and would have meant hauling a grease bucket and pump up 100 feet just to top off a quart of grease.  I don't know about the NOS thing.  I probably would sell the tanks to the guy and let him take the liability of doing the conversions.RogerOld, Tired, and GRUMPYSalesman will call, Batteries not included, Assembly is required, and FREE ADVICE IS WORTH EXACTLY WHAT YOU PAY FOR IT!Dial Arc 250HFThunderbolt 225 AC/DCAssorted A/O torches
Reply:The dry chemical from the fire ext can be put in baggies and used for "chimney bombs".  In the event of a chimney fire you can toss a few down the chimney to get the fire out.  It's pretty common for the fire departments to do that I understand.  Of course it won't save the day if your walls are burning...
Reply:All good ideas and info.Tim Beeker.
Reply:I'd like to have a few just to cut them up and use the metal for projects.  I just cut open an old oxygen cylinder and I'm using the bits and pieces of steel for various projects and scrap.  Man this oxy cylinder have some nice quality 1/4" thick steel!!!!!   Wonder what the fire extinguishers are made of????Lincoln Power Mig 216Lincoln AC/DC-225/125Miller  625 X-Treme PlasmaMiller 211 Forney 95FI-A 301HF 91110Victor Journeyman O/PMilwaukee DaytonMakita  Baileigh NRA Life Member

Reply:I made one into a muffler for a scooter I built when I was 14. It didn;t much muffling but it sure sounded good. I guess 'good' is a relative term in this case.You can always wash your hands.
