The key to achieving safety is to understand what can go wrong.
When dealing with system safety, systematic methods are available
to provide the answer to this question rationally so that a
decision maker can find the most cost effective system improvements
that maximize safety. Over the last several decades, industries
that deal with hazardous operations have developed systematic
methods to address this important issue. Commonly used methods
include:
- Failure Modes, Effects and Criticality Analysis (FMECA)
- Hazard and Operability Study (HAZOP)
- Fault Tree Analysis (FTA)
- Event Tree Analysis (ETA)
- Checklist / What-If Analysis
- Preliminary Hazard Analysis (PHA)
- Cause Consequence Analysis
A large majority of our projects include the application of
one or more of these methods to a system that may present certain
hazards or concerns to management. We select the most appropriate
method based on system characteristics and the needs of our
client. In all of our analyses we not only address engineering
design of the system, we also address system operation, personnel
training, emergency conditions, test and maintenance conditions,
etc. We believe a system safety or process hazard analysis should
address all aspects of system operation including the man-machine
interface.
