Question

Which of the following are included in maintenance and operating costs?

(a) Use of corrosion-resistant material

(b) Loss of product

(c) Regular inspections

(d) Use of corrosion-resistant material and regular inspection

I had been asked this question in an interview for internship.

The doubt is from Corrosion Damage in section Corrosion Principles of Corrosion Engineering

Answer 1

Correct answer is (d) Use of corrosion-resistant material and regular inspection

The best I can explain: Maintenance and operating costs are the preventive measures in order to avoid the plant shutdowns and catastrophic accidents. Plant shutdowns usually cost 5-10 times more than the maintenance and operating costs.
