Why Dust in ATEX Zone 22 Is a Serious Risk

Dust explosions remain a serious threat in industrial settings. Consider the 2008 sugar factory explosion in Georgia: a dust cloud ignited, killing 14 people and injuring 38. The Occupational Safety and Health Administration (OSHA) reported back in 2012 that 130 employees had lost their lives in a period of just over 30 years. During the same period, it reported that 800 more people had been injured due to dust and fine powder fires and explosions.

These tragedies illustrate the devastating consequences of undetected air leaks and unnoticed mechanical faults in dusty environments. In ATEX Zone 22, where explosive atmospheres are rare but possible, reliable tools like the FLIR Si2x-LD acoustic camera are essential for identifying risks before they escalate.

The Dual Threat in Zone 22: Air Leaks and Mechanical Faults

Air Leaks: A Hidden Hazard
Compressed air leaks may seem trivial, but even a small leak can stir up settled dust, creating a combustible cloud. When mixed with air, fine particles like sugar, flour, or chemical powders form explosive atmospheres that can ignite with a single spark.

Mechanical Faults: Ignition Sources
In Zone 22, machinery wear and tear pose a significant risk. Faulty bearings, friction heat, or loose components can act as ignition sources, turning a minor mechanical issue into a catastrophic event.

FLIR Si2x Acoustic Camera: Solving ATEX Zone 22 Challenges
Maintenance managers in Zone 22 environments often face a recurring challenge: pinpointing leaks in compressed air systems within expansive, noisy facilities. These leaks not only waste energy but can stir up dust clouds that pose significant fire risks.

The FLIR Si2x acoustic camera offers an innovative, highly effective solution, combining acoustic imaging technology with ATEX Zone 22 certification to detect and resolve these issues.

Specific Example: Addressing the Pain Point of Hidden Air Leaks in Hazardous Dusty Environments

Imagine a food processing plant where fine flour dust settles near conveyor belts and packaging lines. A minor air leak in a compressed air pipe goes unnoticed, disturbing settled dust and forming a combustible cloud. At the same time, an aging motor begins to overheat due to worn bearings, creating a potential ignition source.

With traditional methods, detecting this leak might require shutting down operations, deploying multiple personnel, and using outdated handheld tools.

Using the FLIR Si2x, the maintenance manager scans the area from a safe distance of up to 200 m (656 ft):

• Acoustic Imaging Mode: Pinpoints the exact location of the air leak on the pipe, visualized as a bright spot on the display.
• Mechanical Fault Detection Mode: Detects abnormal ultrasonic patterns from the overheating motor, identifying worn bearings before they fail.
• Real-Time Data: Displays the severity of both issues and calculates the energy loss from the air leak.

In minutes, the manager has actionable data to prioritize repairs, preventing a potential explosion and costly equipment downtime—all without halting operations.

5 Key Benefits of the FLIR Si2x for ATEX Zone 22 Environments

1. Advanced Air and Gas Leak Detection

Si2x detecting an air leak

The FLIR Si2x uses acoustic imaging to detect leaks in:

• Compressed air systems
• Industrial gases such as ammonia, hydrogen, CO₂ methane, helium, and argon
  

Leaks as small as 0.05 liters per minute can be detected from up to 10 m (32 ft) away, ensuring early intervention.

2. Mechanical Fault Detection

The camera’s mechanical fault detection mode identifies ultrasonic signals from failing components, including:

• Worn or overheating bearings
• Misaligned machinery
• Loose or vibrating parts

Early detection of these issues prevents unexpected breakdowns and reduces the risk of sparks or heat igniting dust clouds.

3. Certified for ATEX Zone 22

Designed for hazardous environments, the FLIR Si2x is fully compliant with ATEX Zone 22 regulations, ensuring safe operation in areas where explosive dust atmospheres may occur briefly.

4. Real-Time Analysis and Cost Estimates
