To ensure the safety and reliability of instrumentation and control systems during seismic events, the following measures shall be adopted: 1. Anchoring of Instrument Equipment Instrumentation equipment such as control cabinets, auxiliary cabinets, instrument panels, instrument boxes, junction boxes, and field instruments shall be firmly fixed to floors or ground using foundations and supports.This prevents

Environmental sustainability and occupational safety are inseparable elements of modern process industries. Instrumentation plays a critical role in monitoring hazardous substances, controlling emissions, and ensuring compliance with environmental regulations. The following guidelines summarize best practices for instrumentation in environmentally sensitive applications. 1. Combustible and Toxic Gas Detection 1.1 Fixed Gas Detection In locations where combustible

1. Introduction Instrumentation in chemical plants serves as the core of process control, safety monitoring, and quality assurance. The acceptance of instrumentation installation directly affects the stability, safety, and accuracy of subsequent operations.Acceptance must strictly follow the “Code for Construction and Quality Acceptance of Automation Instrumentation Engineering” (GB 50093-2013) and special chemical industry regulations (e.g.,

Introduction In high-risk sectors such as chemical, petrochemical, and gas industries, the Safety Instrumented System (SIS) is the final layer of protection. However, design flaws, poor maintenance, and misuse of bypass functions can render this defense ineffective. This document provides a standardized, lifecycle-based SIS inspection checklist, covering design, installation, operation, maintenance, assessment, and documentation. It
