Linseed oil is also a fire risk, as rags can catch fire - especially on hot days. Take extra care when throwing rags in the bin. It is best to wash them. Or throw them where there isn't a risk if they do start smouldering.

Absolutely. Dry the rags opened out on the concrete. Never throw out wet.
Store brushes with oil on them in water.
