SAFETY AND PREVENTION THROUGH DESIGN

The electrical installation should be designed and constructed to be safe by complying with standards, codes, and accepted engineering practices. There are a number of current standards and guidelines for planning and design of electrical power systems for commercial, industrial, and utility applications. Even a well‐designed electrical power system, meeting all the standards and code requirements, may fall short with respect to arc flash hazard mitigation. Prevention through design involves addressing the occupational safety and health needs and redesign processes to prevent or minimize work‐related hazards and risks associated with the construction, use, maintenance and disposal of facilities, materials and equipment. The methodology of evaluating risk and performing reliability analyses applies to any critical facility. The safety lifecycle forms the central framework, and it is a good engineering procedure for safety instrumented systems design in process industry.
