Key Responsibilities and Required Skills for Inspector

🎯 Role Definition

An Inspector performs systematic examinations and verifications of products, structures, equipment, or processes to ensure compliance with engineering specifications, regulatory standards, safety requirements, and customer expectations. This role involves hands-on field inspections, documentation and reporting of findings, coordination with contractors and engineering teams, and recommending corrective actions to resolve non-conformances. Inspectors often apply specialized techniques such as visual inspection, dimensional measurement, non-destructive testing (NDT), and functional testing while operating inspection software and maintaining traceable records.

Core Responsibilities

Primary Functions

Conduct thorough visual and hands-on inspections of components, equipment, structures, and assemblies to verify conformance with engineering drawings, specifications, codes (e.g., ASME, API, ICC) and purchase order requirements; document all findings in standardized inspection reports.
Read, interpret and apply technical drawings, blueprints, schematics, work orders and specification sheets to identify critical dimensions and acceptance criteria during in-process and final inspections.
Perform dimensional verification using precision measuring instruments (calipers, micrometers, height gauges, tape measures) and produce measurement records that support acceptance decisions and traceability.
Execute non-destructive testing (NDT) techniques such as dye penetrant (PT), magnetic particle (MT), ultrasonic (UT), radiographic (RT), and visual inspection (VT) in accordance with ASNT and company procedures; interpret NDT results and escalate anomalies.
Operate and program coordinate measuring machines (CMM) and other automated inspection equipment to verify complex geometries and provide statistical measurement data for quality control.
Create detailed inspection reports, daily logs, non-conformance reports (NCRs) and punch lists; include photographs, measurements and clear recommendations for corrective actions and rework.
Identify, tag and quarantine non-conforming materials, parts and installations; initiate and track corrective action requests (CARs) and follow up to verify remediation and re-inspection.
Perform functional and performance testing of systems and equipment (electrical, mechanical, HVAC) to validate operational readiness and compliance with acceptance criteria prior to handover or commissioning.
Conduct pre-shipment and final acceptance inspections for manufactured goods, ensuring packaging and labeling meet contractual and regulatory requirements.
Execute site-based inspections for construction and installation activities, verify contractor work aligns with approved drawings, schedules and safety plans, and issue field observation reports (FORs).
Conduct safety inspections and hazard assessments on job sites, verify compliance with permit-to-work systems, PPE requirements, fall protection and confined space procedures; report immediate hazards and stop work when necessary.
Coordinate and act as client or third-party witness for pressure tests, hydrostatic tests, load tests and other witness points; document acceptance and test results according to test plans and protocols.
Maintain and verify calibration status of inspection tools and test equipment; coordinate calibration activities and maintain records to ensure instrument traceability and regulatory compliance.
Use industry-standard inspection and workflow software, mobile apps and digital forms (tablet-based checklists) to capture inspection data real-time and integrate with quality management systems (QMS).
Participate in root cause analysis and corrective/preventive action (CAPA) processes for recurring defects; collaborate with engineering and manufacturing teams to implement improvements and error-proofing.
Provide technical guidance and on-the-job training to junior inspectors, apprentices and contractors on inspection methods, acceptance criteria and company quality policies.
Manage inspection schedules and priorities across multiple projects or production lines; liaise with production planners, project managers and procurement to minimize inspection-related delays.
Assist with vendor and supplier audits, review supplier quality documentation, perform receiving inspections and recommend supplier corrective actions when required.
Support commissioning and start-up activities by performing system checks, documenting deficiencies, and verifying remedial work prior to system turnover.
Ensure all inspection activities comply with applicable local, state and federal regulations as well as industry standards (ISO 9001, API, ASME, NEC) and client-specific requirements.
Prepare and present clear, objective inspection summaries and status briefings to project teams, clients and regulatory authorities; maintain professional client relationships during audits and inspections.
Maintain secure, organized inspection files, regulatory documentation and test certificates to support audits, claims and warranty activities.

Secondary Functions

Support continuous improvement initiatives by submitting process improvement suggestions and participating in quality circles or Kaizen events.
Assist procurement with specification clarifications and inspect incoming critical parts to confirm supplier conformance before issue to production.
Participate in emergency response or incident investigations, providing inspection evidence and technical input to root cause analysis.
Maintain and perform routine preventative maintenance on inspection tools and mobile devices; coordinate repairs and replacements as necessary.
Help develop and update inspection procedures, checklists and standard operating procedures (SOPs) to reflect lessons learned and regulatory changes.
Coordinate temporary site access, permits and logistics for off-site inspections, including client notifications and safety inductions.
Contribute to training material development and deliver competency assessments for new inspection personnel.
Support the digitization of quality records by accurately entering historical paper records into electronic quality management systems.
