Do you have any idea about the selection of the explosion-proof lighting fixtures for various hazardous environments. This guide explores the details of explosion-proof light and offers practical insights for choosing the right product to meet your needs.

In hazardous environments, lighting fixtures must meet stringent safety requirements to prevent explosions caused by arcs, sparks, or high temperatures. Explosion-proof emergency lighting not only ensures safety during normal operation but also provides reliable illumination in emergencies. This article details explosion-proof ratings, application scenarios, and the features of JINYI's explosion-proof emergency lighting solutions.

1. Understanding Explosion-Proof Ratings

Explosion-proof ratings are standardized codes indicating the safety and suitability of equipment in hazardous environments. Below are the common ratings and their meanings:

(1) Gas Explosion-Proof Rating (Ex eb ib mb IIC T6 Gb)

• Ex: Indicates explosion-proof equipment.
• eb/ib/mb: Internal protection methods:
  • - eb: Increased safety, preventing ignition sources under normal and fault conditions.
  • - ib: Intrinsic safety, limiting electrical energy below ignition thresholds.
  • - mb: Encapsulation, isolating ignition sources from the external environment.
• IIC: Suitable for the most dangerous gases, such as hydrogen and acetylene.
• T6: Maximum surface temperature of 85°C, ideal for low ignition temperature environments.
• Gb: Suitable for Zone 1 and Zone 2 gas hazardous areas.

(2) Dust Explosion-Proof Rating (Ex tb IIIC T80℃ Db)

• tb: Dust protection by enclosure, preventing dust ingress.
• IIIC: Designed for environments with conductive dust.
• T80℃: Maximum surface temperature of 80°C, suitable for low ignition temperature dust environments.
• Db: Applicable to Zone 21 and Zone 22 dust hazardous areas.

2. Classification of Hazardous Areas

Explosion-proof lighting is chosen based on the classification of hazardous zones:

• Zone 0: Explosive gas mixtures are continuously present (>1000 hours/year), e.g., inside gas storage tanks.
• Zone 1: Explosive gas mixtures occur occasionally (10–1000 hours/year), e.g., near chemical plant equipment.
• Zone 2: Explosive gas mixtures are unlikely but may occur during abnormal conditions (<10 hours/year).
• Zone 20/21/22: For dust environments, Zone 20 indicates continuous dust presence, while Zone 22 indicates infrequent dust presence.

3. Types and Features of Explosion-Proof Emergency Lighting

Based on application scenarios and functionality, explosion-proof emergency lighting is categorized as follows:

(1)Explosion-Proof Exit Signs

• Features: Clearly indicate escape routes with high-brightness LEDs for long-lasting visibility.
• Applications: Ideal for Zone 1/Zone 21 environments to mark safe exits.

(2) Explosion-Proof Twinspot Lights

• Features: Dual independent light sources provide wide illumination coverage.
• Applications: Suitable for high-visibility zones in Zone 1/Zone 21 environments, such as warehouses and corridors.

(3) Explosion-Proof LED Battens

• Features: Linear LED fixtures with options for LED boards or tubes, offering uniform lighting with low energy consumption.
• Applications: Designed for Zone 2/Zone 22 environments in industrial facilities and storage areas.
