  • Routine Maintenance, Inspection & Contractor Management: Governance of scheduled maintenance, breakdown response, contractor selection and induction, and permit-to-work arrangements.
  • Isolation, Lockout & Stored Energy Management: Protocols for isolating pressure, steam, electrical and fuel energy sources, including lockout/tagout and verification of zero-energy state.
  • Emergency Preparedness, Response & Incident Management: Planning for boiler-related emergencies, alarm response, evacuation, fire and explosion scenarios, and post-incident investigation.
  • Documentation, Change Management & Technical Control of Information: Control of drawings, P&IDs, operating manuals, and formal management of change for plant, process and software modifications.
