Best answer
The correct choice is (b) False

Explanation: In non-ferrous foundries, there can be chances of a generation of combustive dust particulates which are safely collected by dust collecting equipment. But keeping of this system with heating system might ignite the dust particles which in turns to fire or explosion in the foundry. So it is very necessary to keep dust collecting systems away from the heating systems.
