Our engineering team facilitate and document Process Hazards Analysis (PHA) in accordance with the ISA/IEC 61511 Functional Safety – Safety Instrumented Systems for the Process Industry Sector and OSHA Process Safety Management (PSM) Standard 29 CFR 1910.119 standards. Experienced in chemical process, control systems, and the standards, our members can facilitate HAZOP, LOPA, HAZID, Security PHA Reviews, and other studies including documentation.
Process Hazards Analysis (PHA)
Process Hazards Analysis (PHA) — including a full range of facilitated/workshop studies like HAZOP, LOPA, HAZID, and a full-range of auditing.
PHA studies are easily documented and audited in Open-PHA™ HAZOP/LOPA Documentation Software, and Open Audit™ Documentation Software.
Hazardous and Operability Studies (HAZOP)
Hazard and Operability (HAZOP) studies provide recommendations based on causes and consequences that require further attention.
Layer of Protection Analysis (LOPA) & Quantitative Results Analysis (QRA)
Layer of Protection Analysis (LOPA) is commonly used to assess the risk of the areas identified in the HAZOP to determine the target Safety Integrity Level (SIL) required to reduce the risk to an acceptable level. LOPA uses semi-quantitative techniques to deal with probabilities.
Complex scenarios are analyzed using Quantitative Results Analysis (QRA) potentially in a fault-tree tool like Arbor™.
LOPA studies are easily documented in software tools today like Open-PHA™.
Security PHA Review
Security PHA Review -was developed by Kenexis and is a disciplined approach to reviewing a PHA, especially a HAZOP, for cybersecurity threat vectors that have consequences.
You can read more about in our Post or get the book at Security PHA Review.
Continuing Engineering Support
Functional Safety Management Program maintenance is challenging. Our Continuing Engineering Support team provides a consulting engineer to assist your team as required. Our team of chemical engineers and functional safety experts are available for short or extended periods to function as part of an engineering team for something as simple as verifying SIL calculations or as complex as audits.
