Question

Electrical equipment is also used along with the dust collecting equipment to control ignition of combustible dust particles in the foundry.

(a) True

(b) False

This question was posed to me in examination.

The question is from Dust Collecting Equipment topic in division Foundry Environment Health & Dust Problem in Foundries of Casting-Forming-Welding I

Answer 1

The correct option is (a) True

Explanation: In the foundry, the processes involved in the production of castings like melting, pouring and solidification generates combustible dust particulates which may even burst due to the presence of high pressure, which can cause explosion in the foundry. So, appropriate electric equipment and wiring methods should be used for controlling spark or ignition of dust particles.
