This post made me run out and check...as Tex described I have a green button on top.
Bill, wasn't aware of the powder settling, I'll have to check that now.
I did a brief google search and learned that inside an RV we should have BC type extinguishers. I assumed the ABC like in my home would be better, but I guess BC are non-toxic and ABC are toxic and corrosive.
Going to poke around a bit more on this topic, but thanks again to the OP for asking and the others for the information. Again, something I hadn't thought much about before but probably should from now on. A fire in a RV could get out of controll very quickly.
