Introduction
The following specifications are provided to assist clients and partners in providing Process Hazard Analysis (PHA) information and related data to Risk Alive for the purpose of generating analytics.
In this document, “PHA data file” refers to digital data recorded during a process hazard identification and risk assessment session, using a recognized and generally accepted PHA methodology. (e.g. HAZOP, What-If, LOPA)
PHA Data File Specifications
File Types
Risk Alive accepts PHA data in the following formats:
IDEAL | PHA Pro PHA Works Microsoft Excel CSV (exported from PHA software) |
ACCEPTABLE* | Microsoft Word Adobe PDF (converted; not scanned) |
NOT ACCEPTED | Scanned Adobe PDF (text as image) |
Languages
PHA data must be provided in English language.
PHA Methodologies
The PHA methodology used by the client and their adherence to generally recognized and accepted engineering practices as it relates to each of these methodologies may affect the scope and reach of the analytics.
IDEAL | HAZOP LOPA What-If? CHAZOP |
ACCEPTABLE | HAZID |
Other PHA methodologies not listed above may also be submitted for evaluation.
Data Quality
Data quality with respect to PHA data is a subjective measure. Risk Alive will not reject data files based on data consistency issues but these issues may impact analytics output or require the client to confirm assumptions reached related to the data interpretation and conditioning process.
Examples of data quality, consistency issues include:
Inconsistently applied safeguard risk reduction credits
Poorly or insufficiently described consequences, causes, safeguards, etc.
Lack of safeguard information (e.g. providing only a tag number)
