ICH Q7 clause 3: Personnel

Staffing must be sufficient for the workload with qualified personnel. Qualification criteria include: education (typically degrees relevant to the role), training (GMP and job-specific), experience (years in similar roles). Written responsibilities (job descriptions, responsibility matrices) prevent ambiguity about who does what. Under-staffing leads to shortcuts and quality failures.

Two training dimensions: (1) GMP fundamentals (applicable to all employees performing GMP work) and (2) job-specific training on SOPs, techniques, and equipment relevant to the individual's role. Initial training before independent work is essential. Ongoing training keeps personnel current with procedure updates and emerging practices. Training effectiveness should be assessed, not just attendance recorded.

Training records are the regulatory evidence of employee competence. Each employee's file should contain dated training records with: course title, date, duration, trainer, and effectiveness assessment results. Periodic competency assessments (observations, tests, practical evaluations) verify retention. Retraining is triggered by procedure changes, performance issues, or scheduled cycles.

Personnel hygiene prevents microbial contamination of products. Key controls: exclusion of ill personnel from production areas, proper hand washing, grooming (clean fingernails, no heavy cosmetics), no eating/drinking in production areas. Personnel with open wounds or infectious diseases should be restricted from production until cleared. This clause includes a positive responsibility for supervisors to observe and act on health issues.

Protective clothing has two purposes: protecting the product from personnel contamination and protecting personnel from the process. Clothing requirements vary by area: street clothes in offices, lab coats in general production, full gowning in cleanrooms or with potent APIs. Hair covering, beard covering, gloves, and eye protection may be required. Changing frequencies must be defined — daily typical, more frequent for high-risk areas.

Direct skin contact with intermediates and APIs should be avoided through engineering controls (closed systems, automation) and protective equipment (gloves, sleeves, face shields). Where direct contact is unavoidable (e.g., sampling, manual charging), techniques must prevent contamination: sterile or cleaned gloves, clean sampling tools, limited exposure time, and environmental controls.

Dedicated break rooms/cafeterias separated from production prevent contamination. Common controls: physical separation with doorways/airlocks, signage at entry to production, enforcement during walkthroughs, training reinforcement. Smoking is prohibited in all production areas (often the entire facility). Personal medications are prohibited to prevent accidental contamination if containers spill.

Proactive reporting of health issues prevents contamination. Personnel must feel comfortable reporting without fear of reprisal. Conditions to report: infectious diseases, gastrointestinal illness, respiratory infections, skin conditions, open wounds. Supervisors need training to recognize issues that employees may not self-report. A clear return-to-work procedure with medical clearance ensures safe return.

External consultants are commonly used for specialized areas: regulatory strategy, validation, specialized analytical methods, facility design. Like employees, consultants must be qualified for the advice they provide. Documentation of consultant qualifications (CVs, certifications, prior engagements) should be retained. Consulting services should be governed by written agreements defining scope, deliverables, and confidentiality.

Consultant records create the audit trail for external advice. Content: consultant name, company, contact information, qualifications, date(s) of engagement, scope of services, deliverables produced, compensation (optional but good practice). These records should be readily available during audits to demonstrate that any external advice came from qualified sources. Retention periods should match other GMP records.
