👉 ISA (International Safety Instrument 1) engineering refers to the systematic approach and technical implementation for ensuring safety in industrial processes by reducing or eliminating hazardous conditions. It involves the design, development, and installation of safety instrumented systems (SIS) that monitor process parameters and automatically take corrective actions to prevent or mitigate hazardous events. The ISA framework is structured around five main phases: hazard and risk assessment, safety integrity level (SIL) determination, system architecture design, implementation, and verification. Engineers use this methodology to create robust, reliable safety systems that comply with international standards, thereby enhancing overall process safety and reducing the risk of accidents.
