90% of Explosion Accidents Are Caused by Incorrect Equipment Selection!

This Guide Makes Hazardous Area Operations Safer

Industrial explosions are devastating—yet most are preventable. The wrong explosion-proof equipment is often the culprit. How do you ensure safety in hazardous environments? This Explosion-Proof Knowledge Guide breaks down the essentials for proper equipment selection.

1. Understanding Explosion-Proof Markings

Every explosion-proof device carries critical markings, such as:
Gas Ex db ⅡC T6 Gb / Dust Ex tb ⅢC T85℃ Db

This code reveals:

Ex db = Flameproof protection (for gas environments)

ⅡC = Highest gas hazard level (hydrogen, acetylene)

T6 = Maximum surface temperature ≤ 85°C (safest rating)

ⅢC = Highest dust hazard level (conductive metals like aluminum/magnesium)

Our products meet these top-tier standards, ensuring maximum safety.

2. Mainstream Explosion-Proof Types

※ Our products use Flameproof (Ex db), ideal for high-power industrial applications.

3. Equipment Classification: Gas & Dust Hazards

Gas Explosive Environments (Class II)

ⅡA (Low risk) – Propane, butane

ⅡB (Medium risk) – Ethylene, industrial gases

ⅡC (Highest risk) – Hydrogen, acetylene

Dust Explosive Environments (Class III)

ⅢA – Flammable fibers (cotton, wood)

ⅢB – Non-conductive dust (flour, coal)

ⅢC – Conductive dust (aluminum, magnesium)

※ Our equipment covers ⅡB, ⅡC (gas) and ⅢC (dust)—the most hazardous conditions.

4. Temperature Ratings: Why T6 is the Safest

※ Our products are T6-rated—the strictest safety standard.

5. Hazardous Area Zoning: Where to Use Which Equipment

Gas Environments

Zone 0 – Constant explosion risk (e.g., inside fuel tanks)

Zone 1 – Occasional risk (e.g., chemical reactor areas)

Zone 2 – Rare risk (e.g., outdoor loading zones)

Dust Environments

Zone 20 – Constant dust clouds (e.g., inside silos)

Zone 21 – Occasional dust (e.g., conveyor belts)

Zone 22 – Rare dust exposure (e.g., filter leaks)

※ Our products are certified for Zone 1/2 (gas) and Zone 21/22 (dust).

Conclusion: Choose the Right Protection, Avoid Disasters

Explosions don’t happen by chance—they happen by choice of equipment.. With flameproof (Ex db) construction, ⅡC/ⅢC ratings, and T6 thermal safety, our solutions ensure compliance with the strictest global standards.
