Talking of dust and bringing this back to railways, having dismantled several old carriage bodies for spares, removing the roof canvas with many, many layers of old white lead paint results in clouds of unpleasant dust which gets everywhere. Although dangerous, this is perfectly legal with no controls.
Applying for a licence to use new white lead on a carriage roof however means jumping through hoops including things like where and how you will dispose of brushes and rollers in double sealed plastic bags, whether the carriage will be stored outside where eventually the paint will wash into the watercourse etc etc
Anyway, if for a model you ever examine a preserved carriage with wooden roof, remember that the roof finish is almost certainly not the correct canvas and white lead, for the reasons above.
