Equipment status monitoring: install explosion proof emergency exit lights next to the paint spraying robots and drying ovens, approving red\/green dual-color lights to provide real-time feedback on equipment failures [e.g. red light alarm for exceeding VOCs concentration].<\/p>\n\n\n\n

Emergency exhaust linkage: integrated gas detection module indicator, in the VOCs concentration \u2265 25% LEL triggered sound and light alarm and linkage exhaust system, synchronized start emergency lighting.<\/p>\n\n\n\n

2. Battery assembly and testing area<\/strong><\/strong><\/h3>\n\n\n\n

Hydrogen leakage warning: deploy explosion-proof emergency lights around the fuel cell stack and hydrogen pipeline, activate high-frequency flashing and voice prompts when the hydrogen concentration is \u226510% LEL.<\/p>\n\n\n\n

Charging and discharging safety guidance: set up direction-indicating Explosion proof emergency exit lights in the area of charging and discharging test bench, with ground illumination \u22655lx in case of sudden power failure, and arrows guiding the safe evacuation paths.<\/p>\n\n\n\n

3. Welding workshop and assembly line<\/strong><\/strong><\/h3>\n\n\n\n

Welding spark protection: Adopt explosion-proof grade Ex d IIC T4 indicator lamps with surface temperature \u2264135\u2103 to prevent splash sparks from igniting.<\/p>\n\n\n\n

AGV navigation marking: low-glare explosion proof emergency exit lights are installed in the automatic guided vehicle [AGV] channel to ensure that the path is clearly marked 24 hours a day to avoid collision accidents.<\/p>\n\n\n\n

Third, the automotive plant explosion proof emergency\u00a0exit\u00a0lights selection and technical guidelines<\/strong><\/h2>\n\n\n\n

1. Certification and compliance requirements<\/strong><\/strong><\/h3>\n\n\n\n

International explosion-proof certification: must be approved ATEX [II 2G Ex d IIC T4 Gb], IECEx or China CNEx certification to adapt to Zone 1\/Zone 2 hazardous areas.<\/p>\n\n\n\n

Industry-specific guidelines: comply with ISO 9001 quality management system and IATF 16949 automotive industry-specific requirements.<\/p>\n\n\n\n

2. Fundamental technical parameters<\/strong><\/strong><\/h3>\n\n\n\n

Light source performance: LED light source light efficiency \u2265 140lm \/ W, color temperature 5000K [neutral white], color rendering index Ra> 85, accurate identification of wire harness color and assembly details.<\/p>\n\n\n\n

Emergency range capability: according to GB 51309-2018 guidelines, the evacuation channel needs to be equipped with an explosion-proof emergency indicator with a range of \u2265 180 minutes.<\/p>\n\n\n\n
