Safety risk assessment begins with hazard identification, followed by elicitation of causes that could result in those hazards. Cause identification early in the design phase is function‐based by necessity, since components and sub‐systems are not fully defined. These system functions are defined by the product requirements. Applying HAZOP guideword analysis to product requirements can provide a list of initial hazard causes and functional failure modes of the system. This method provides early insight into safety risk controls that should be planned for and implemented early in the product design, when cost and schedule impacts are lowest.
