To work around a hot smoker I take along a metal coffee tin and at the end of the beekeeping session I empty the contents of the smoker into the tin and put the lid on.
The tin has a slightly smaller diameter than my smoker and so I then sit the sealed tin in the smoker. By the time I've taken off my suit the smoker, having no fuel in it has cooled down, the tin is airtight so the fuel has gone out, there are no embers left on the ground so no fear of setting light to grass, hedge and I am not leaving unsightly marks on the ground when in an out apiary.
And best of all, when I next go to use my smoker, either the same day if I have hives in different locations or the following week if not, I have a small tin full of part burned fuel which lights easily.
The coffee tin I use is made by Illy, it's on the top shelf with the premium coffee at Tesco
