Explosion proof evacuation indicator light is an emergency lighting device specifically designed for flammable and explosive hazardous areas, mainly used to guide personnel to evacuate safely in emergency situations such as fire, explosion, power outage, etc. Its design must meet special requirements such as explosion-proof, fireproof, and high brightness to ensure reliable operation in harsh environments.

　Suitable for

Flammable and explosive areas such as petrochemicals, natural gas stations, and coal mines;

Places with combustible dust such as pharmaceutical factories and flour processing plants;

Closed spaces such as tunnels and underground facilities;

Other industrial or public areas that require explosion-proof certification.

　　Structure and maintenance requirements

Convenient maintenance design

Explosion proof indicator lights typically require a quick maintenance structure, such as a front cover design that can be flipped open to facilitate internal component or battery replacement and avoid overall disassembly.

Explosion proof shell certification

It must comply with explosion-proof electrical equipment standards (such as GB 3836), and the material and sealing of the shell should meet the explosion-proof level requirements (such as Ex d IIB T6) to ensure safe operation in flammable and explosive environments.

　　Installation specifications

Installation height and spacing

The height of the indicator sign from the ground should be below 1.0m, and in difficult situations, it can be set at 2.2m~3.0m.

The distance between signs on evacuation corridors should not exceed 20m, and signs should be added in corner areas.

Distribution reliability

Explosion proof places should adopt centralized power supply systems to ensure power supply reliability.

The distribution circuit shall not cross the fire compartment, and an emergency lighting distribution box or centralized power supply shall be independently installed in the smoke proof staircase.
