How long is the shelf life?
The Prepared Hero Dry Stop Fire Spray manufacturer recommends replacing unused canisters every 6 years to ensure reliable performance in an emergency.
Would probably have bought a combo pack of 2+2, but don’ want to spend 60 bucks for 4+4.
@cfg83 insulated bags will slow thermal exchange, not stop it entirely. Eventually it will normalize to ambient. Unless you are constantly taking the extinguisher out and putting it back every day.
Am I missing something, or just getting mixed signals here?
“The portable aerosol can is lightweight and easy to store in kitchens, vehicles, backyards, and other convenient locations” Do not leave in a vehicle
Do not store in location hotter than 120°F

It’s easy to store ice cubes in your trunk, but not practical/recommended either…
@cfg83@chienfou@suprchunk@thevorlon There are times and places where the temperature in a car/trunk will not exceed 120°F. Presumably it is safe to store this in a car in those conditions.

@Fuzzalini There was a run of Adidas items a couple of weeks ago and I started it then. I enjoyed the nostalgia so kept it going, adding in the Beastie Boys, Flavor Flav, and Stephen Tyler. This one was my favorite.
In my younger adventuring days in a 4WD pickup, I had a Halon extinguisher strapped between the big bench seat and the driver door. Truck was big enough there was room; theoretically you could reach down from the driver position and unlatch the strap. Fortunately, was never needed.
As an inert gas don’t think there were long term chemical aging concerns as there would be with these. But, CFCs, Yay! Not sure you can still get them. Used to be common in boats, race cars, computer rooms.
Edit: I remember larger boats also also some race cars had automated emergency Halon systems. And once at work I set some big electronic equipment on fire (not intentionally, I swear!). And it was a holiday weekend. Fire dept responded with oxygen masks as they routinely do now. Later found out the automatic Halon system had been disabled for years.
@pmarin We can still get and carry Halon and Halotron for use in aircraft. The prices are becoming insane though as I think they’re mostly filled with recycled product now.
@pmarin@Polymathic halon hasn’t been really manufactured for decades. It’s been 100% recycled for a while now.
The chemicals don’t go bad. That’s sort of why they are bad greenhouse gasses as they are relatively inert (HFCs moreso than CFCs). They escape and don’t do much but don’t break down.
What goes bad, is usually the container seals, if anything. But for insurance and safety purposes guaranteeing 5-10yrs is easier.
This offer is misleading. I thought FIRE SPRAY meant that the spray would go on fire, not extinguish it! I got so many pests I still need to get rid of!
What am I going to do now???
I don’t know if this is the case for the liquid version of these but I once tracked down the fill of a similar aerosol can fire fighting product after I used it on a grease fire in a gas grill. They had basically taken an AFFF (aircraft fire fighting foam) product and packaged it in a spray can.
I purchased the Dry Stop here in June 2025 (2@ $24). the QC date on the bottom is 07/2023 so these 2 cans should be okay through 07/2028 at least according to the manufacturer. I’m going to get the Vapor Clean (can be sprayed on humans) now, at this lower price point and probable same date of manufacture.
You should have an extinguisher in every room of your home and make an effort to remind yourself of locations on the regular (like, say, every time you vacuum or something). It can mean the difference between a large inconvenience and a tragic/total loss.
@Pufferfishy yes, especially if you use a fireplace, woodstove, barbecue on a porch, or just love fiery cooking!
But also know when it’s time to head for the hills (outside) and call 9-1-1
After saving the cats, of course.
We have the fire blankets now. Same company. Easier to use in high stress emergency, even for kids. No fiddling with the pins or figuring out how to use it. No worries about what kind of fire it is. You can store it in your car. Grab it and throw it over the fire to snuff it out.
/image Prepared Hero fire blanket
We’ve got big ones in the house & garage, but I’m keeping a few of the dry ones where they’d be needed quickly (near the 3D printer, wire welder etc.).
I was going to ask, but i looked it up instead. expired fire extinguishers (not refillable or you’re not going to refill it) should be taken to a hazardous waste facility that accepts them. some counties let you put completely empty ones in the trash (but not recycle bin).

@phendrick I will NOT do this, but if you kept the bottle in an insulated bag in the trunk, would that be a viable way to keep it from overheating?
@cfg83 insulated bags will slow thermal exchange, not stop it entirely. Eventually it will normalize to ambient. Unless you are constantly taking the extinguisher out and putting it back every day.
@cfg83 @jamesmcp
this!
Man, under the grill grate is where I keep my charcoal!
No info on what their expiration date is?

“The portable aerosol can is lightweight and easy to store in kitchens, vehicles, backyards, and other convenient locations”
Do not leave in a vehicle
Do not store in location hotter than 120°F
@thevorlon might be safe storing it in the trunk where it’s cooler?
@thevorlon @Trogdor248 Yeah, I asked if you put it in insulated bag to keep under more temp control.
@thevorlon
Sooooo, not legal in Arizona?
@cfg83 @thevorlon
Just because it’s “easy to store” there doesn’t mean you should!
@cfg83 @chienfou @thevorlon …then why say it is a storage option? Since you are defending the corporation here, I assume you have your answer ready?

Yeah, it’s the new Georgia red/margarita…
¯\_(ツ)_/¯
@macphoenix @Michaelforman Maybe they got Stephen Tyler and Joe Perry conflated?

@macphoenix Thank you for the correction.
Unexpected mention in the writeup! Mom is gonna laugh.
@PooltoyWolf
You definitely dodged a bullet that day. I’ve seen way too many grease fire results in my ER…
@chienfou Good thing I was nearby and acted quickly!
@PooltoyWolf
Keeping your head in an emergency is a useful skill!
What’s the date stamp on the bottom? 31,000 units were recalled!
@el1c1a Production Date: 09/2024
Expiration Date: 09/2029
0T600 66240. VT
@el1c1a Are these part of the recalled ones?
@el1c1a @gwrankin
Given recall regs, I’m guessing no.
Seems like an ok deal. What is the lifespan on standard fire extinguishers?
@cfg83
Typically 10+ yrs for regular disposables.
In my younger adventuring days in a 4WD pickup, I had a Halon extinguisher strapped between the big bench seat and the driver door. Truck was big enough there was room; theoretically you could reach down from the driver position and unlatch the strap. Fortunately, was never needed.

@pmarin
I think the halon BB date issue would likely be pressure leak over time…
@pmarin We can still get and carry Halon and Halotron for use in aircraft. The prices are becoming insane though as I think they’re mostly filled with recycled product now.

This offer is way too Hot for me!
This offer is misleading. I thought FIRE SPRAY meant that the spray would go on fire, not extinguish it! I got so many pests I still need to get rid of!
What am I going to do now???
Ok. Who in sam-hell did the naming and packaging?
It says Vapor “CLEAN”, It’s in a BLUE bottle and it says FIRE SPRAY.
Is it an air freshener, a window cleaner or an arson essential?
Someone panicking after starting a margarita induced kitchen fire is not going to innately grab a blue bottle of “spray”.
@Sorry_Nothing So I should not grab the Windex to put out my inevitable frying-turkey fire?
@macphoenix
No, definitely not. That’s for wound care…
I don’t know if this is the case for the liquid version of these but I once tracked down the fill of a similar aerosol can fire fighting product after I used it on a grease fire in a gas grill. They had basically taken an AFFF (aircraft fire fighting foam) product and packaged it in a spray can.
@Polymathic
Pro tip… Don’t eat whatever you were cooking once it has been applied!
@chienfou @Polymathic Mmmm, Spicy!

Sure, I’ll take advice from the paid-actor “Firefighter” trying to sell these things; seems a bit inept to be offering any believable sales pitch!
@MrGoodGuy that’s a nomex compression arm sleeve. all the cool firefighters wear them
@walarney Oops! Thanks for the correction. I thought he’d burnt himself already.
@MrGoodGuy oh, no! I was just being a smart ass
@walarney Well, Double Oops then!! The “firefighter” is still a dork!!

Buy one for each meh $5 lithium battery/phone charger pack
@username There’s a good business model.
