DIY Fire Extinguisher Answered

I need a cheap homemade fire extinguisher for small stuff.



A good general extinguisher is fine sand - it smothers most fuels, cools flames, and anything it can't cure is not made worse (unlike water of a grease fire!). Plus, it is easy to clear up afterwards, just sweep or hoover.

Thanks for the tip. I have plans for a Co2 fire extinguisher now. Thank You :-)!

In Canada, we have a chain of Greocery stores called Zehers. they sell a line of there own products.... they sell one time use non-rechargable ABC fire extinguishers for like 5 - 10 bucks. I keep one of those around just in case.....had to use it once and it worked great......large enough that they can put out small to medium size fires and small enough that there cheap. Maybe you could find something like that in your area

The goal of a fire extinguisher is to smother the fuel source of a fire, so that oxygen can't reach it. So to make an effective one, you'd want to make a sticky, heat resistant paste to pressurize (with c02, preferably) for spraying onto the fire.

I call it water in a bucket. A hose mix vinegar and baking soda in a bottle, and somehow compress it.

. Water is not the best choice for a home extinguisher. Very poor at grease/oil and electrical fires.
. CO2 is effective on most fires and leaves no residue. Harder to handle than messy (but quite effective) baking soda.
