Fire Extinguisher Case as a Water Bottle? Answered

I went to test an old 2lb fire extinguisher we had by pressing the green test button and, it didn't work. The fire extinguisher was a BC type dry chemical fire extinguisher. The label reads (CONTENTS OF BC DRY CHEMICAL POWDER: SODIUM BICARBONATE, MICA, CALCIUM STEARATE, NUISANCE DUST, IRRITANT; HMIS 0-0-0.)
I took the chemical out to use as crude sodium bicarbonate, and now I want to use the bottle. My plan is to keep the labels on, find a cap like they use on most aluminum water bottles, and clean the inside out really well. The question I have is, is it safe? It says the contents are non-toxic, but I would still want to clean it really well. What would I clean it with? Would I have to coat the inside of the bottle because of the metal, (powder coating type place) and if so, what type of coating? Thanks! 


it will be perfectly safe......or you could ust get a actual water extinguiser.On Ebay I sell them seller ID Allmercy just do the advanced search by seller and put my ID in and buy one or two or ten.

I could just buy a water bottle and paint it red, but that's why I just used the empty fire extinguisher I had! :)
A quick rinse with concentrated Acetic acid and dilute sodium hydroxide and any residue was gone, so it was perfectly safe in the end.
I really want to try the idea of pressurizing the bottle in some way (like a commercial water extinguisher) and being able to squirt water into my mouth, but commercial extinguishers have far too much pressure to be practical, and pressurizing a water bottle period isn't very practical.
Thanks for the tip though!

I think this would be a fun concept, but not a good idea. Besides the aforementioned health risks, what would happen if someone reached for this in an emergency[ex: grease fire in the kitchen with the water bottle on the counter]?

If you do convert it, you should paint it a cool color, such as blue or green("cool" in reference to the color spectrum) so as not to confuse it with an actual fire extinguisher.

You'd have to be pretty silly to think about using a red bottle with no top on it to extinguish a fire when everyone in the house knows the fire extinguisher is under the sink and the baking soda is on the shelf.
It doesn't matter anyway as I don't use it as a water bottle very often since I can't find a reliable cap. Thanks for the advice though!

Made into a seltzer bottle it would definitely be a conversation piece.

or cut out the bottom and weld a slightly smaller then the original case tube to it, so it slips up inside, and you could have a nice hiding place for things.

Some definitions: Nuisance Dust: Dust Sampling Nuisance dust is considered to be the total dust in air including inhalable and respirable fractions. Various dust sampling methods exist that are internationally recognized. Inhalable dust is determined using the modern equivalent of the Institute of Occupational Medicine (IOM) MRE 113A monitor (see section on workplace exposure, measurement & modeling). Inhalable dust is considered to be dust of less than 100 micrometers aerodynamic equivalent diameter (AED) that enters through the nose and or mouth.

HMIS 0-0-0 can be found here..


Mica, although not poisonous
, you would not want to swallow large quantities of it....


For the rest, follow Caitlinsdad's advice :-)

I don't think I'll have to worry about the chemicals much then. Thanks for the links!

Maybe you should call a local shop that services fire extinguishers for businesses, they are in the phone book. They might be able to tell you if it has been done or if it is safe since they deal with maintaining and servicing fire extinguishers. Good luck.

Good idea, I actually have connections to a local fire extinguisher company that I'll probably give a call.

Give it a good rinse out with plenty of hot water, scrub with a bottle-brush and rinse again, you'll be fine...

... except ...

What's the bottle made of? If it's steel, you're going to get rust. If it's aluminium, you're going to get aluminium in your system (inconclusively linked to Alzheimer's).

You may be able to work out if it is already coated - have a look with a torch, prod with a finger, or maybe check for electrical continuity?

The bottle is aluminum, I'll probably do the continuity check although the opening is very small.
