Design for safety

Developers coming into safety-related projects for the first time are particularly seeding guidance in microprocessor-based electronics, where the designer has previously been concerned primarily with exacting the most economic utilisation from the minimum component count. This paper summarises some important considerations in design of a safety-related microprocessor-based system. It considers preliminary hazard analysis, requirements specification, the conflict between safety and reliability, safety evaluation techniques and design for assessment.<
