What is Inerting?

Inerting is a safety process where inert gases are introduced into confined spaces to displace oxygen and prevent unwanted combustion or explosive reactions. This vital procedure helps maintain safety across various industries, from aviation to chemical processing.

In this guide, you’ll learn all you need to know about inerting:

• How it works
• When it’s used
• What gases it uses
• How to perform it safely

The Fundamentals of Inerting and Why It Matters

Think of inerting as creating a protective bubble around sensitive materials or processes. By introducing non-reactive gases like nitrogen or argon, you can effectively eliminate the risk of fires and explosions in spaces where flammable materials are present.

The process works by reducing oxygen levels below the point where combustion can occur. While air typically contains about 21% oxygen, inerting can lower this to safer levels – usually below 8% for most applications.

What makes inerting particularly valuable is its versatility. Whether you’re dealing with fuel storage tanks, chemical reactors, or even electronic component manufacturing, this process can be tailored to meet various specific safety requirements.

Essential Applications Across Industries

Inerting is used in many industries, most notably:

• Aviation: in aviation, inerting systems are crucial for preventing fuel tank explosions. These systems continuously monitor and maintain safe atmospheric conditions in aircraft fuel tanks.
• Chemical industry: chemical and petrochemical facilities rely heavily on inerting for their day-to-day operations. Here, the process helps protect reactive materials during production, storage, and transportation.
• Food production: Food and beverage manufacturers use inerting to extend product shelf life and maintain quality. By removing oxygen from packaging, they can prevent oxidation and spoilage.
• Electronics: Electronics manufacturers depend on inerting during soldering processes. The technique prevents oxidation on circuit boards, ensuring higher quality connections and more reliable products.

Choosing the Right Inert Gas for Your Application

Nitrogen stands as the most popular choice for inerting applications for several reasons:

• Cost-effectiveness
• Wide availability
• Extreme stability under most conditions

Another popular option is argon, which is particularly useful in specialized applications where absolute purity is crucial. While it’s more expensive than nitrogen, argon’s complete inertness makes it ideal for sensitive processes.

Finally, carbon dioxide can be effective for certain applications, especially when a heavier-than-air gas is needed. Still, it requires careful consideration due to its potential to form carbonic acid in the presence of moisture.

Best Practices and Safety Considerations

Successful inerting requires more than just introducing an inert gas – it demands careful monitoring and control. Here are the best practices to follow:

• Conduct regular testing of oxygen levels. Doing so ensures the atmosphere remains safe and stable.
• Perform proper training of personnel working with inerting systems. Workers need to understand both the benefits and potential hazards associated with reduced-oxygen environments.
• Ensure proper ventilation and safety protocols. While non-toxic, inert gases can create oxygen-deficient atmospheres that pose serious risks to human health.

Support Inerting With a Reliable Gas Supply

Whether you’re looking to implement a new inerting system or optimize an existing one, having a reliable gas supply partner makes all the difference. They should have extensive experience and a comprehensive gas portfolio to ensure your inerting processes run safely and efficiently.

If you’re unsure which gas to choose, consider reaching out to your supplier’s technical team to discuss your specific inerting requirements. They’ll help you maintain the highest safety standards while maximizing operational efficiency.
