  • Contamination Control, Cleanliness and Infection Prevention Systems: Controls for particulate, moisture, oil and microbial contamination, cleanroom practices where applicable, and integration with infection prevention requirements.
  • Testing, Verification and Commissioning Management: Governance of pressure testing, leak testing, purity testing, functional verification and independent commissioning sign-off prior to clinical use.
  • Integration with Building Services, Fire Safety and Emergency Systems: Assessment of interfaces with HVAC, electrical, alarms, fire detection and suppression, and emergency shut-off arrangements.
  • Worker Health, Fatigue and Psychological Safety Management: Systems for managing shift work, fatigue, exposure to clinical environments, stress, and psychosocial risks for project personnel.
  • Site Access, Security and Public / Patient Interface: Management of contractor access, security clearances, segregation from patients and visitors, and protection of vulnerable persons in healthcare settings.
  • Emergency Preparedness, Incident Response and Business Continuity: Planning for gas leaks, loss of supply, contamination events and other emergencies, including escalation pathways and continuity of critical clinical services.
