GB/T 47438.4-2026

This standard specifies the technical requirements, performance testing, and operational protocols for portable display devices that receive and visually present fire alarm and evacuation information in hazardous chemicals workplaces. It is applied in chemical plants, storage facilities, and industrial sites handling dangerous substances, ensuring that mobile personnel can access real-time alarm data and evacuation instructions when away from fixed display panels. The standard is critical for safety management systems in high-risk chemical environments, particularly during emergency response and personnel evacuation scenarios.
