I now read more closely (my bad) But Halotron, basically a repurpose of the refrigerant HCFC123 with some additives has its own issues.

In fact HCFC123 is being phased out as a refrigerant because it also is an ozone depleting gas. Not as severe as Halon, but severe enough that there is an international agreement to stop using it in new equipment in 2020 and no longer be available for repairs in 2030.

As a firefighting agent, it was developed and is marketed by a company that uses a website of the same name, Halotron.

It is apparently not approved as a firefighting agent in residences. If you read through the whole SDS (formerly MSDS) sheet you might think twice about using it, at least without self contained breathing apparatus.

Quoting from the SDS:Precautionary Statements:
P261: Avoid breathing vapors/spray
P271: Use only outdoors or in a well-ventilated area
P304+P340: IF INHALED: Remove person to fresh air and keep comfortable for breathing
P 312 Call a POISON CENTER or doctor/physician if you feel unwell
P403+P233: Store in a well-ventilated place. Keep container tightly closed.
P405: Store locked up
P501: Dispose of contents/container to an approved waste disposal plant

Information pertaining to particular dangers for man and environment: Inhalation of high concentrations of
vapour may cause central nervous system effects such as dizziness, drowsiness, anesthesia, or unconsciousness.
When used on a fire, hazardous decomposition products are formed, but typically are within safe emergency
exposure limits. Misuse or intentional inhalation abuse may lead to death without warning.

And you might want to also read the SDS for the HCFC123 which is 96 percent of the Halotron mixture. Do you really want to breathe this stuff?

Personally, I'd stick to a CO2 extinguisher. Yes, CO2 can be injurious, but at greater concentrations.

Beyond that, which is more important, your equipment or your life or health?

I removed "storage" from your list.

Halotron looks the least scary, if injected intravenously See SDS for the other common extinguishers, they look as bad if not worse.

I rarely use SDS because you don't know quantities, concentrations or context. They list things that COULD happen in the worst case.
You could die if you drink too much milk.

Having a house on an island off the grid, I like to read the magazine Cabin Life.

One way a backwoods cabin owner set up to help save a cabin from a forest fire.
1. You need a close by Pond or Lake.
2. Purchase a water trash pump and some large 2 inch hose to pickup from the
lake and hose to a large sprinkler.
3. Large sprinkler head
4. Clear all the brush and trees around your hose to have a fire break.

Of course someone has to start the water pump, remotely or by your neighbor. Pre soak your house before the wildfire reaches you and the fire may jump your cabin.

The house will have water damage like drywall, electronics, plaster, and furniture. But you can save your house.

The key is to have a fire hose style hose to put enough water on your cabin while waiting for the fireboat. A garden hose will not put enough water on a house.
