ATEX Compliance and Safety

At Hosokawa Micron, we help clients ensure their processes and equipment comply with ATEX regulations, protecting employees and assets while maintaining operational efficiency. With decades of experience in powder and solids processing, we understand the challenges of potentially explosive atmospheres and offer tailored solutions to address them.

Understanding ATEX

ATEX regulations govern equipment and workplace conditions in environments where explosive atmospheres may occur. These regulations include the ATEX 153 (99/92/EC) directive, which focuses on workplace safety to protect employees, and ATEX 114 (2014/34/EU), which applies to equipment and protective systems designed for use in potentially explosive atmospheres.

How Explosions Occur

An explosion occurs when three elements—fuel, oxidant, and an ignition source—converge under the right conditions. Common fuels include flammable dusts, gases, or vapours; the oxidant is typically air; and ignition sources can range from hot surfaces to sparks or static electricity.

Static electricity, in particular, is a frequent and dangerous trigger. In powder processing, the movement or agitation of fine particles generates electrostatic charges. If not properly managed, they can ignite combustible dust clouds, with potentially catastrophic consequences.

Our Expertise

Hosokawa Micron designs and modifies systems to address these risks. We integrate explosion prevention measures without compromising performance or product quality. Whether you require new equipment or need to upgrade existing Hosokawa Micron systems, we ensure ATEX compliance while optimizing operational efficiency. We also stay ahead of regulatory changes, advising clients on necessary updates to maintain compliance over time.

Addressing ATEX Risks

At Hosokawa Micron, we combine our expertise in powder behaviour with a detailed understanding of ATEX regulations to mitigate explosion risks. Our approach begins with analyzing each customer’s specific situation. This includes assessing the properties of the materials being processed, such as particle size, flammability, and combustibility, which play a critical role in determining the potential hazard.

For instance, organic powders like starches, sugars, and milk powder are highly flammable, especially when finely milled. Similarly, combining powders with liquids or solvents can release flammable gases, which pose additional risks. By thoroughly assessing all these factors, we can recommend solutions tailored to your specific process.

Solutions for Safe Systems

To minimize explosion risks, our experts focus on preventing ignition sources and controlling atmospheres. Key measures include:

• Developing conductive and grounded equipment to prevent static buildup.
• Creating inert atmospheres to eliminate oxygen in critical zones.
• Installing safety devices such as burst plates, flame arrestors, and pressure relief systems.
  
  

For existing equipment, we assess compliance and suggest practical upgrades. Even a single uncertified component in an otherwise compliant system can compromise the entire setup. We provide practical solutions to address these challenges without sacrificing efficiency or product quality.

Beyond Compliance

ATEX compliance is an ongoing process. Regulations evolve, and systems may need updates to meet new standards. Our experts monitor these changes and provide guidance to keep your operations safe and compliant. We also assist with hazard zone classification, a key requirement of ATEX 153, ensuring both equipment and environments are thoroughly evaluated to prevent accidents.

Partnering with Hosokawa Micron

Explosion prevention demands technical expertise and a deep understanding of regulations. At Hosokawa Micron, we offer more than compliance support—we provide peace of mind. Whether designing new facilities or retrofitting existing Hosokawa equipment, we help you implement effective safety measures to protect employees and maintain efficient operations.
