I purchased a 2.5# Ansul CleanGuard extinguisher last year. It contains DuPont FE-36 (HFC-236fa) and is rated for 2-B,C.

I paid around $90 for the extinguisher w/bracket and hose. It's mounted to my hauler.

I see it as a relatively inexpensive safety measure/requirement. Admittedly, I haven't had to use it yet - so I don't know what a refill will cost. Or if will be cheaper to simply buy another new one.

Cheers!

*****
Ansul CleanGuard® extinguishers are designed for the protection of commercial and industrial facilities traditionally protected by Halon 1211. Typically, these areas contain sensitive or irreplaceable equipment which could be damaged or destroyed by water, foam, dry chemical, or carbon dioxide. Typical applications include computer centers, data/document storage areas, communications facilities, control rooms, electronics manufacturing, museums, art galleries, laboratories, and many others.
DuPont FE-36 replaces Halon 1211 as the agent-of-choice for applications where the agent must be clean, electrically nonconductive, environment-friendly, extremely low in toxicity and exceptionally effective. Because it discharges as a liquid, FE-36 also provides an effective discharge range up to 16 ft. (4.9 m). FE-36 is electrically nonconductive, residue-free, and will not cause thermal shock damage. FE-36 has been accepted by the EPA for commercial, industrial, and military use under the EPA’s SNAP program. It boasts zero Ozone Depletion Potential and is not scheduled for phase-out by the Montreal Protocol as is Halotron I.
