Thanks for the video. I had just purchased this model after some research. Since I've never used an extinguisher before, I liked how you showed how to activate it.
Very nice video. I especially liked the suggestion to twist the pull ring forward until the tamper seal breaks. This is great for someone who has limited grip/pull strength in their fingers and hands.
Okay a semi-recent video, that's good. So the model B402 is, as best I can tell, physically identical to the B500. But the B402 is rated 3A:40B:C, whereas the B500 is only rated 2A:10B:C. They're both equipped with 5 pounds of the same chemical, they both weigh 9.25 pounds. So why does the B402 have a higher rating when it comes to square foot coverage?
Thanks for the question! The B402 and the B500 are both the same extinguisher with the main difference being the nozzle at the end of the hose. The smaller nozzle on the B402 is basically a straight point-and-shoot type which focuses more of the dry chemical agent in in one spot which gives the operator an advantage of more knock down power, while the B500s larger nozzle offers wider dispersion but it disperses the agent more gently. With the difference between both types, the B402s nozzle has better efficiency than the original 2A:10B:C rated hose. Hope this helps! I’m eventually going to make a video comparing both the B402 and the B500 (I own both models) to show the difference between the two units.
@@ztobinz One website that reviewed these 2 fire extinguishers said that the B500 used an "older formula" powder whereas the B402 used a newer one, but didn't specify any further.
I would mainly just check the pressure gauge occasionally (more often if exposed to the elements) and make sure the tamper seal is in good condition and not broken. If you take care of it, not only will it last many years to come, it will care of you when it’s needed the most.
Huh. I've been scouring the videos of FireAlarmDude to find the video where he talks about the chain pin retainer setup, and it turns out I was checking the wrong place this whole time. I forgot about this video. Anyway the 4th of July is coming up faster than any of us are prepared for, and I want to get a spare 5 pound extinguisher for the family in case of grass fires developing. More convenient than carrying around a 3 gallon bucket of water, or keeping the garden hose on at all times and having to drag it around. Would the 500 or the 402 be a better option in the event of a grass fire developing?
It’s not a bad idea to have a fire extinguisher handy for July 4th. I would best recommend the B402 for its higher UL Rating. The B402 has a rating of 3A:40B:C verses the B500 having a rating of 2A:10B:C, so the B402 can extinguisher more fire for its capacity.
Dude, the fire didn't go out because you were in another zip code when you deployed the powder. Get closer next time and fight the fire rather than run from it.
thank you for this test its great to add to my safety page! I am a fire equipment consultant sorry did not finish reading thte description hope you dont mind if I add any relvant videos to my safety page! please allow me to add any relavant videos to my page I can include a link to the original youtube postings !!!!
@@zachsafarik5218 Hi Zach got a research question for you do you think since it seem the largest size advertised for home grease fires is 10 B that a 20 B rated unit will be adequate size for a home grease fire? Thoughts please thank you
@@Fredengle Yes, absolutely. The lowest Class B rating that I would recommend is 10B (2.5 pound dry chemical unit) for its agent capacity in a smaller unit. Otherwise anything over 10B will work without to much trouble. You can’t go wrong with having too much UL Rating such as putting out a small 5B rated fire with a 80B rated extinguisher. Plus the extra capacity can come in handy in case of re-ignition. When in doubt, chose an extinguisher with a higher UL Rating for the needed application.
@@zachsafarik5218 Hi Zach here is something you may not have known while abc can take away a grease fire did you know due to its phone being an acid it possibly less effective on a grease fire than Pk or baking soda the reason for that is both Pk and baking soda da are an alkaline scientific lay it should be more effective because it should generate a soap in contact with hot grease!
Very nice I just bought 1 of these of Amazon for $60. Great extinguisher, proudly made in the USA

Glad I could help!

Absolutely!
I've always seen a plastic pin retainer on them but cool modification.

The B402 is filled with a different dry chemical, Amerex's 555 powder. The B500 is filled with a more standard ABC powder.

I just purchased this model. Are there any guidelines for inspecting it periodically?

You are way too far from fire
