Omg me too. I service so many fire extinguishers at work as well. I can’t stand seeing the shitty work of everyone else. It pisses me off because I know if that it was an emergency and I wouldn’t work. It infuriates me that people don’t care so much as we both do.

👍🏻👍🏻👍🏻👍🏻👍🏻

Certainly

I worked for a company that did fire extinguisher service and maintenance . Pretty much all the work we did was of the highest quality. We never left anything to chance. If there was anything questionable about a given unit we would run it through a battery of tests, including full discharge and recharge to make sure the extinguisher would not fail if needed to fight a fire. We understood that if a unit fails to operate properly in an emergency it would be a heavy strike against the quality of our work. We understood that in the fire protection business there is no room for failures . I can't speak for other companies. When done properly a refilled / recharged unit is just as reliable as a brand new unit .

@@skrettsnerk508 true true. But the company was the one buying the wd40

I save it from other factory charged extinguishers. I always separate them by brand to avoid mixing powder

Fines are the very small particles you see floating off. In the powder, the different grains of powder are different sizes. Some are coarser than others and the fines are the very fine powder particles that are important in extinguishing a fire. The more you lose, the less effective the powder will be.

UL rating is based on NITROGEN, which adds to the effectiveness.

I believe that’s OR27

@@FireAlarmDude5967 ok thanks

Yeah they are the exact same as in o ring and valve stem. The difference between 500 and 402 is the hose. 500 has a cone shaped end and the 402 has the smaller shaped hose tip that keeps the same circumference.

The coupling is just a standard air coupling.

Don’t hit the extinguisher’s handle. If you need to, perhaps you can use a pipe wrench or channel locks. It is against manufacturer recommendations but I think it would help

It is certainly simple but requires a lot of equipment and is not worth it for an average person.

I’m certainly not licensed. And yes I would never offer this service to anyone else just for the sake of liability

I can definitely tell you're not licensed, absolutely the incorrect way to perform a 6-year maintenance @@FireAlarmDude5967

You do put air into any extinguisher. Rewatch the video. You use nitrogen and only nitrogen.

If you’re using a hand pump you probably aren’t pressuring it enough. You need to get to 100 PSI. If you’re sure that you’re getting to 100 PSI, the gauge is probably just bad. Water can gauges especially are prone to failing

@@FireAlarmDude5967 I fill it 3/4 and I only get arround 40/50 psi but when it gets sprayed most of the water is ejected.

@@FireAlarmDude5967 and it’s also only a 6L water

@@JC09_lvp right so that’s why your gauge won’t move. Regardless of size they’re pressurized to at least 100 PSI. For a 1.5 gallon or “6 liter” unit 100 PSI would be the nominal pressure

@@FireAlarmDude5967 so should I start filling it half way becuase it won’t go anything over 40/50 psi. Also would my other one not work because it was made for powder and was 1kg for powder also it has been bullied (the gauge)

It's about $300 to $375 for a 50 pound pail of Amerex ABC dry powder. About $40 for the nitrogen regulator. First buy of a nitrogen cylinder is around $350 USD... but it only costs $35 to $40 thereafter to get it recharged. Getting spare parts for extinguishers, and the adapters, would be another minor investment. End of the day, you're not going to do this for your average home fire extinguishers that are seldom, if ever, used. It would be cheaper just to let a licensed extinguisher service do the job for you. On the other hand... if you're in a business where you end up using the extinguishers a lot, and don't want to be doing without a charged extinguisher handy? THEN it might be worth it to go ahead and make your own little investment to support your own extinguishers. To put this in perspective for you... my first fire department... we were ALL trained to service our own extinguishers, and had the spare parts and such to do it with. It was one of our chores we did, along with recharging our SCBA (breathing air) bottles. And if we got detailed to our headquarters station (and everyone would!), we'd also get trained in hydrostatic testing, and we'd hydrostatically test our fire extinguishers and air bottles sent in from each station. MOST fire departments, do NOT maintain this capability. They contract at LEAST hydrostatic testing out, and honestly, most departments don't bother with recharging their own dry chemical or CO2 extinguishers, either, because candidly, we don't use them very much. So it's easier and cheaper to contract with a local fire extinguisher contractor to handle it. The only extinguisher that most fire departments can recharge in-house, is the 3 gallon water extinguisher, which you obviously just fill with tap water, and pressurize with the same compressed air hose you'd use to air-up your vehicle tires. Used properly, it'll pack a punch and knock down a ton of fire, as you can see in the following video. kzfaq.info/get/bejne/f7qZjbVknrnKlZs.html At the end of the day... I would agree... it's usually cheaper and easier/less time-consuming, to just write the check to the fire extinguisher service company local to you, and let them sweat the charging and testing of fire extinguishers.

There is nothing wrong with refilling it yourself, provided you are familiar with the refill and maintenance process. Otherwise its probably best to have a reputable company that stands behind their work 😂refill it for you. They have the facilities and equipment needed to run any and all tests on the unit as well as any parts that may need replacement, i.e valve stems, hose, pickup tube, etc. This way you are assured you have unit you can rely on in an emergency.

Takes maybe 10 minutes

No because I have no way of doing a hydro test

Traded it from someone else

I did a job and it was really strict about fire watching when cutting rebar and they throw out a few, I should have grabbed a few

Hilarious

@@FireAlarmDude5967 i know right, peak comedy

Lol

I print them myself

@@FireAlarmDude5967 That's really cool! Is TZ your own "brand"?

Air can only be used with water extinguishers

Elaborate. Claims with no reasoning don’t mean anything

@@FireAlarmDude5967that was a perfect explanation. Only thing I would say is make sure to include the head and hose when weighing the powder (unless you already calculated that before) . Great vid. I do around 125-150 of these a week 🤣.

Appreciate the feedback
