Breaking Down Silos: The Interdependence of Electrical & Instrumentation, Equipment, and Safety

The idea that electrical and instrumentation (E&I), equipment, and safety are “three independent silos” is a perspective that may seem plausible but does not reflect reality in well-managed organizations. However, in situations where communication and management are lacking, such silos may indeed arise, leading to inefficiencies or even operational risks. Understanding the Roles of E&I,
