Abstract: Based on the latest Chinese national electrical codes, the paper systematically elaborates on the design essentials of fire emergency lighting and evacuate indicating system in cement engineering projects.The design deviations because of the inconsistent standard terminology definitions and varying clause requirements, the paper integrated the requirements of nearly 10 standards which including GB55037-2022 and GB17945-2024. The paper summarized the latest requirements for the setting of emergency lighting, illumination requirements, system classification, luminaire selection, and power supply method selection. Additionally, we have clarified the design flow sheet in this paper. Firstly, select a central or non-central fire emergency lighting system based on the project requirements and determine the illumination requirements of the site. Secondly, comprehensively select the type of lighting fixtures, color temperature, protection level, and other six dimensions, and adjust the battery configuration based on the new standards. Finally, the design is completed by standardizing the selection and wiring design of the power distribution box. It provides systematic guidance for electrical engineers to carry out fire emergency lighting and evacuate indicating system design for cement engineering projects within the framework of the new standard.
