If it will put out a fire, it can and will likely kill living things.

I ain’t no fire scientist. I have been through Damage Control school, survived a pretty bad fire at sea, been an engineering officer for afloat units and owned a boat of my own.

My view is very simplistic. Fires require oxygen. Most things designed to put out a fire do that by removing access to oxygen. Yep, that includes water. Enclosed or semi enclosed spaces don’t have lots of oxygen. Plants, animals and MDS members all need oxygen last time I checked. I know for sure I don’t want to be in a fight for oxygen with things like carbon dioxide, purple K, AFFF or halon. I know how that ends.

Sprinkler system is your best bet besides good risk management.

Just one fellas opinion.

One common dry chemical fire extinguisher filler is sodium bicarbonate. Baking soda.

It is treated with some additives to keep it from clumping, but basically baking soda.

Keep it clean.
Rigorous NO SMOKING!
Store Hay/Straw in a separate building far enough away that a fire there won't jump to the barn no matter which direction the wind is blowing.
Lighting rods.
Heat/Smoke Detectors that notify you.
Have a farm pond with a dry hydrant hookup for the fire fighters water supply.

Correct. That will usually be the extinguishers with a B:C rating on the label. If the label on the dry chemical extinguisher shows A:B:C dry chemical, then what you have is typically mono-ammonium phosphate; which can be pretty aggressive on metals in the presence of moisture (after the fire). Some of the smaller extinguishers use mono-ammonium phosphate but do not carry the A rating because there is not enough of the agent in the extinguisher to put out the test fires at UL. (The A and B ratings will have a number preceding each letter; the number indicates the size of the UL test fire that the extinguisher can be expected to extinguish when used by an 'untrained' person. For reference, a 2-1/2 gallon water extinguisher has a 2A rating.)

If an extinguisher does not have the UL mark, don't count on it. It might work when you need it, it might not.

P.S. The fire 'balls' or 'grenades' as we used to call them do not have a UL mark because UL does not have a test standard for them. They probably never will have a standard for those products.

And what happens if the fire isn't in a box and the ball keeps on rolling past the fire or the fire starts 6 or 10 feet away from the wall mounted ball. I think they are a false security building solution and you better have a solid fire prevention and fire extinguishing plan first.
