FIRE EXTINGUISHER YES OR NO
Things to consider:
Which can you afford?
To repair or replace.
Insurance will probably come closer on the dollar for repair but will probably come up considerably short on replacement.
If it catches fire, do you want to save it or roast marshmallows while waiting for the fire department?
You will want a fire extinguisher classification A,B,Ç. This rating is for textiles, liquid, electrical. Most in that class are powder and extremely messy as they crust on contact with hot surfaces. (Clean up time consuming)
The larger the extinguisher, the more fire fighting capability you will have. But even then, duration of discharge will be limited to seconds. Storage will dictate size.
@aobfarm be aware... The military went full bore on halon extinguishers... shortly after deployment throughout all branches, young folk started having heart attacks. The military restricted use of halon to outside areas only. None to be used in enclosed spaces. Turns out that halon and adrenaline caused irregularities in the heart.
