OK, so now that my parents split up and my dad has moved out, I can poke around the garage without fearing for my life if one of his things gets broken, moved out of place, or generally breathed on. In the process of doing this, I noticed that the garage fire extinguisher is older than I am, and was last charged/inspected in March of '79. The little dial thingie is too scuffed up to read, but I doubt that the fire extinguisher would really extinguish anything very well.
So, what I’d like to know is: can this fire extinguisher be charged up/filled up so that it’s actually useful? Where do I go to do this? And if it can’t, what’s the correct way to go about disposing of it? Also, how much do you suppose a couple old rotary phones would fetch me on E-Bay?
