Occupied Building Safety (Facility Siting) according to API752/75

Our experts have carried out risk studies relating to occupied buildings for nearly 40 sites in total in the Americas and in Europe.

PSI (Process Safety Information) and Safeguarding Manual

Safety Documentation System for a Production Unit :

• Maximum safe flow
• Overpressure protection (safety valve, depressurization valve)
• Overheating protection
• Dust explosion
• Any other protective devices (fireproofing, pump protection, HC detectors, critical tracing etc. )
• Operational constraints (start, stop)
• General breakdown (electric, air, cooling water)
• Identification of high– and low-pressure interfaces
• Process protection barriers (safeguarding drawings)

Review of Process-Related Risks (Process Hazard Analysis, PHA)

• Qualified facilitators
• What-if, HAZOP, LOPA, FMEA, SIL determination, Bow-tie Analysis (Basic, cyclical, revalidation)
• Consequence analysis using :
  • Semi-quantitative tools for toxic and fire/explosion substances using the Dow : Fire and Explosion Index (F & EI), Dow Chemical Exposure Index (IEC)
  • Quantitative impact analysis for toxic and fire/explosion substances using Trace® and Phast
  • Quantitative Risk Analysis (QRA) (individual and societal risk assessment) using Safeti®
