Let me simplify cgwaite:
Burning some liners releases toxic pollutants. Avoid breathing these fumes.
Same goes for the dust when you grind off what's left of the liner. If you deceide on using a lined drum, take these precautions and, when your done clean it out with strong detergent & water. Then wait a day or 2. If it uniformly rusts, its clean and good to go.
