“There is a clear case to put the money into the design of the product, and control that, than relying on the human factor.”
In this Let’s Talk Risk! conversation, Alex Saegert highlights the importance of focusing on risk reduction through safety by design, rather than relying on information for safety to users. He recommends risk practitioners to apply best practices from systems safety to build a clear understanding of system-level hazards that lead to harm in a hazardous situation through a sequence of events. Understanding the sequence of events can help create a more robust design to minimize the probability of occurrence of one or more elements involved.
He reminds us that there are tools available that can be applied without significantly increasing complexity of the design. Additionally, he recommends linking hazard analysis to design controls (DFMEA) and process controls (PFMEA) to reduce and control probabilities of occurrence of the events that contribute to hazardous situations, while maintaining traceability between hazards and control actions.
