Introduction
In hazardous industrial environments—such as oil & gas plants, chemical processing facilities, offshore rigs, and mining operations—one wrong electrical component can trigger a catastrophic explosion. Choosing the right explosion-proof solutions is not just a technical decision; it’s a critical safety requirement.
This 2025 guide will help facility owners, HSE managers, and engineers understand exactly how to choose the right explosion-proof systems—and how Ex Industries provides certified, globally compliant solutions for every hazardous zone.
1. Understand Your Hazardous Area Classification
Before choosing equipment, you must identify the correct classification for your facility:
- Zone 0, 1, 2 (Gas)
- Zone 20, 21, 22 (Dust)
- Class I, II, III (North America)
- Division 1 or 2
If your team is unsure, Ex Industries engineers can assist with verification and recommendations.

2. Choose Certified Equipment Only
The most important rule: Only purchase equipment with valid ATEX, IECEx, NEC, UL, or CSA certifications.
Ex Industries provides fully certified products across global regions.
3. Select the Right Enclosure Type
Explosion-proof enclosures are designed to protect electrical components and prevent ignition sources.
Types include:
- Flameproof (Ex d) – Contains internal explosions
- Increased Safety (Ex e) – Prevents sparks & hot surfaces
- Purge Systems (Ex p) – Removes flammable gas/dust by pressurizing the enclosure
4. Select the Correct Cable Glands (Most Ignored, Most Critical)
Cable glands maintain explosion-proof integrity and are one of the most important components in hazardous installation.
Select based on:
- Material (Brass, Stainless Steel 316L)
- Temperature Rating
- Cable Type
- Seal Type
- Explosion-proof certification

5. Install the Correct Accessories (Drains, Plugs, Adapters)
Accessories ensure proper installation and prevent issues like condensation, pressure buildup, or improper threading.
6. Consider Intrinsic Safety for Control Systems
For control rooms, low-voltage devices, sensors, transmitters, and instrumentation—Intrinsic Safety (IS) is often the safest and most cost-effective option.
