I attended a face-to-face technical interview with the client in Kochi. The interview had a moderate difficulty level, covering various technical aspects related to my expertise. It required in-depth knowledge and practical problem-solving skills.
Interview questions [3]
Question 1
1. What are the key differences between IEC 60079-14 and IEC 60079-17, and how do they apply to hazardous area installations and inspections?
2. How do you determine the correct equipment protection level (EPL) for an installation in a Zone 1 hazardous area, and what factors influence the selection of Ex d, Ex e, or Ex i equipment?
3. During an inspection, you find a gland with an IP66 rating installed on an Ex d enclosure in a Zone 2 area. What checks would you perform to ensure compliance, and what potential non-conformities might exist?
