Verification per Section 4.7: (a) Clear verification via representative sampling and read-back testing, (b) Purge verification via sampling and laboratory verification techniques where stakes warrant, (c) Destroy verification via visual inspection + chain-of-custody documentation + photographic evidence where appropriate, (d) document verification methodology + sampling rationale + verification results per sanitization batch. Audit and continuous improvement: (a) periodic internal audit of sanitization program per Chapter 5, (b) review of Certificate of Sanitization records for completeness + accuracy + consistency, (c) trend analysis on sanitization volume + method distribution + verification failure rate + vendor performance, (d) external audit by regulator or independent assessor as required. Personnel training per Section 3.2: (a) initial training for personnel handling media for sanitization covering policy + methods + chain of custody + recordkeeping, (b) refresher training annually, (c) specialised training for sanitization technicians + ITAD vendor managers + records custodians. Environmental + Safety Controls per Section 2.5.3: (a) follow OSHA + environmental regulations for destruction methods (shredder safety + chemical handling + incineration emissions + dust + noise), (b) protect operator safety with PPE + ventilation + ergonomic equipment, (c) coordinate with sustainability + recycling programs to minimise waste.
