Electrical and Instrumentation Inspector

Job Overview

Ex Equipment Inspection

• Inspect Ex-rated electrical and instrumentation equipment in classified zones (Zone 1, Zone 2, and Gas Groups IIA, IIB, IIC), including:
• **Motors**
• – flameproof (Ex d), increased safety (Ex e), and non-sparking (Ex nA)
• **Junction boxes**
• – Ex e, Ex d, Ex tb
• **Instruments**
• – pressure transmitters, temperature sensors, flow meters, analyzers, and gas detectors
• **Switchgear**
• – Ex de, Ex e enclosures
• **Cable glands, conduit systems, and sealing fittings**
• **Lighting fixtures, alarms, and beacons**

Installation Compliance Verification

• Verify installation compliance with:
• **IEC 60079-14**
• – Design, selection, and installation of Ex equipment
• **IEC 60079-17**
• – Inspection and maintenance of Ex installations
• Check:
• Correct equipment grouping and temperature class (T1–T6)
• Proper ingress protection (IP rating as per area classification)
• Appropriate cable gland type (Ex d barrier glands for flameproof, Ex e compression glands for increased safety)
• Earthing and bonding continuity
• Armor terminating and drain/stop boxes where required

Inspection Types (Per IEC 60079-17)

• Conduct
• initial inspections
• (new installations before energization)
• Conduct
• periodic inspections
• (scheduled based on area zoning and risk assessment)
• Conduct
• sample inspections
• (spot checks for ongoing compliance)
• Inspection grades to include:
• **Visual**
• – identification of visible defects
• **Close**
• – detailed examination with covers opened (if safe)
• **Detailed**
• – full inspection with equipment partially dismantled (where permitted)

Area Classification & Documentation Review

• Review
• area classification drawings
• and verify:
• Zone boundaries (Zone 0, 1, 2 for gas; Zone 20, 21, 22 for dust)
• Equipment selection matches classification
• Gas grouping (IIA, IIB, IIC) and temperature class requirements
• Review equipment schedules, loop drawings, and instrument index

Deficiency Identification & Reporting

• Identify and document deficiencies including:
• Missing or illegible Ex labeling / rating plates
• Incorrect cable glands (plastic vs. metal, wrong type for Ex d)
• Damaged or corroded equipment entries
• Missing blanking plugs or stopping boxes
• Improper sealing or cable installation
• Failed earthing or jumpers disconnected
• **Raise Inspection Findings and Non-Conformance Reports (NCRs)**
• with photographic evidence and code references
• Follow up on corrective actions and close-out verification

I&E Instrumentation Activities

• Review:
• **Loop testing records**
• (4–20 mA, analog and discrete)
• **Calibration records**
• for instruments in hazardous areas
• **HART**
• communication and configuration files
• **FOUNDATION Fieldbus**
• (FF) segment documentation, wiring, and terminators
• Verify smart instruments are properly addressed and configured per loop drawings
• Witness loop testing or calibration if requested by client

Coordination & Reporting

• Liaise with client (QatarEnergy / operator), EPC contractor, and subcontractor E&I teams
• Attend pre-commissioning, inspection walkdowns, and punch list meetings
• Prepare and submit daily inspection reports, punch lists, and final Ex inspection dossiers
