Safety Critical Task Analysis (SCTA)
A Perspective on Injury Prevention
Safety Critical Tasks when initiated incorrectly can result in catastrophic failure such as loss of plant integrity. This failure can be contributed to system software error, human error, equipment failure and / or design error or inadequate risk analysis etc.
Safety Critical Task Analysis can include:
- Quantitative data metrics
- The alert of key component failure / maintenance / prior learning
- System Life cycle
- Hierarchical Task Analysis
- Human Failure Analysis
- Performance Influencing Factors
- Assessment of Task Complexity
- Significant Hazard Risk Register
- Identify main major accident safety hazards. (safety reports, risk assessments, industry sector incidents)
- Safety Critical Task determination
- Hierarchical Task Analysis
- Safety Critical Task Analysis / review all stages of procedure / human factors / cognitive / interface design / training /
- Control measures
- Review controls
