Major incidents in the chemical and process industry have resulted in companies adopting new strategies to incorporate the use of performance-based standards into their overall safety philosophy for dealing with risk reduction methods.
Compressed project schedules, limited staff accessibility and engineering cost procedures drive the need to integrate HAZOP and SIL/LOPA studies. Furthermore, the IEC 61511 promotes the benefits of a tight relationship between the two.
LOPA compares the risk of a process without safeguards to that with safeguards. The delta Risk is evaluated using tools (matrices) based on “ALARP” to suggest how much mitigation (quantified using IPLs and SILs) is required.
Western Canada’s chemical and process industries have a good track record in safeguarding their workers, the public, the environment and their assets, having not experienced a truly horrific disaster. But is this luck that will eventually run out?
