Scope

Main Technical Content: Foreword 1 Scope 2 Normative Reference Documents 3 Terms and Definitions 4 Basic Conditions for Implementing Demonstration Operation 5 Prevention of Hazards During Operation 5.1 Hydrogen Leakage, Combustion, and Explosion 5.1.1 The layout of equipment within the power station should be reasonable, ensuring sufficient safety distances between key equipment such as hydrogen delivery pipelines and storage containers. 5.1.2 The ventilation design should ensure effective air circulation within the station to maintain hydrogen concentrations in hydrogen-related enclosures below 25% LEL. 5.1.3 The power station should be equipped with high-precision hydrogen monitoring devices with appropriate ranges to real-time monitor hydrogen concentrations within the station. Monitoring points should be distributed rationally, including critical locations such as hydrogen storage areas, along delivery pipelines, and near fuel cell stacks. 2T/DHFCA 6–2025 5.1.4 Develop an operating manual, and operators should perform tasks in accordance with operating standards. When conducting hydrogen-related operations such as filling and equipment maintenance, necessary safety measures such as using explosion-proof tools and conducting gas replacement should be implemented. 5.1.5 Conduct regular maintenance and inspections of hydrogen storage containers, delivery pipelines, and fuel cells every quarter or semester. 5.1.6 The power station should establish comprehensive emergency response plans, including procedures for handling hydrogen leaks and explosions. The plans should clearly define the responsibilities of various departments and personnel during emergencies. 5.2 Electrical Shock Hazards After the power station is shut down, it should be discharged, inspected, and confirmed to be free of high voltage before being touched. 5.3 High Temperature, High Pressure, and Chemical Hazards 5.3.1 During normal operation, high-temperature and h
