In this case, you just smash the flasme in the floor and then throw in the trash. There is minimum hazard of the thing catch fire, specially if it has a cover.

Many places have designated trash for butts.

Where I work, thare is a company that collect these cans, and transform in paper.

After 2 years they are now being proffiteble.

But as a smoker, I fell terrible when there is a trash can in the place, but there are lots of butts in the floor. Makes me mad.
