Two pans, one is setting on the floor till the coals are cold then dump it in a plastic trash bag and remove from the house, no dust flying around. the other in the stove.
I line a kitchen trash bag (13gal.) with the tough bags the coal comes in, place the ash pan inside tempoaryily close up the bag air tight and dump the ash, let the dust settle awhile in the bag before removing the ash pan. then seal up the trash bag and throw out with the regular trash. No going out in the cold to dump the ash pan, no dust in the house, no dust flying around outside. I keep the weight of the trash bags under 20lbs. so no complaints from the trash pick-up guys.
