I need to ask this question from Mechanization topic in division Foundry Mechanizations of Casting-Forming-Welding I

Answer 1

The correct option is (a) True

The best I can explain: Dust content of the air is generally kept low in some modern foundries, thus reducing the hazards to the workers. In sand moulding, the sand might get into the bearings of a roller conveyor or the moving parts of machines. Many foundry machines breakdowns due to the presence of sand or dust in the air.
