Prioritising Safety in Hazardous Environments

At Thorne & Derrick, safety isn’t just a priority—it’s the foundation of everything we do. That’s why we were privileged to participate in the pilot delivery of the groundbreaking CompEX Level 1 Ex Awareness Course, hosted by Roxby Training Solutions at their Stockton training centre.

As trusted industry experts, we were invited to provide critical feedback on the course’s structure and delivery. Two of our team members—Terry McDonald (Safety Champion) and Regan Redpath (Apprentice Sales Engineer)—took part, achieving outstanding results:

  • Regan Redpath became the first individual ever to pass the course.
  • All T&D hazardous area specialists hold current CompEX Certifications (EX F/F+).
  • Terry McDonald, our Safety Champion with 20+ years of experience, provided invaluable insights to shape future course improvements.

— Regan Apprentice Sales Engineer, First to Pass CompEx Level 1 Ex Awareness Course Delegate Testimonial: Regan’s Experience

“The course provided a clear and straightforward overview of hazardous areas—what they are, why they exist, and the potential dangers they pose. The content was well-structured and easy to follow, perfectly outlining essential safety measures to follow in such environments. This training is incredibly valuable and will benefit anyone who works in or accesses hazardous areas, ensuring they stay safe and informed.”

— Regan Apprentice Sales Engineer, First to Pass CompEx Level 1 Ex Awareness Course 


Compex level 1 ex awareness course

CompEx

The CompEX Level 1 Ex Awareness Course provides essential training for professionals who:

  • Enter or visit hazardous sites (e.g., engineers, logistics personnel, or site visitors).
  • Perform hands-on trades (e.g., scaffolding, electrical work, welding, or mechanical maintenance).
  • Design or specify ATEX/IECEx equipment.
  • Deliver products or services into hazardous zones.

This training goes beyond basic compliance to deliver real-world benefits:

  • Fewer incidents – because educated teams spot risks before they become emergencies
  • Greater confidence – standardised knowledge means everyone works from the same safety playbook
  • Watertight compliance – not merely passing ATEX/IECEx tests but actually knowing them

Thorne & Derrick can be safely trusted to specify and supply electrical, mechanical, process, and instrumentation equipment for use in hazardous areas zones and explosive atmospheres.


The Critical Need for Hazardous Area Awareness

In industries where a single spark can be catastrophic, standardised safety training isn’t optional— The CompEX Level 1 Ex Awareness Course addresses:

  • The hidden risks in Zone 0/1/2 environments
  • Common misconceptions about ATEX/IECEx compliance
  • Practical protocols that prevent incidents before they occur

This course is a major step forward in bridging the knowledge gap for newcomers to the industry, offering a course demonstrating the risks, hazards, and essential safety protocols for working in explosive atmospheres (Zone 0/1/2).

The Fire Triangle


SPECIAL THANKS

“Thank you to Roxby and CompEX for the invite to participate in and provide feedback on the very first Ex Awareness (Ex A) Level 1 course. Having worked in the industry for almost 2 decades, one thing that no longer shocks me is the difference in levels of competency from company to company and industry to industry. Any course that can help improve knowledge and awareness can only be a big positive.

The course provides a very basic introduction to hazardous areas, highlights the hazards/risks and demonstrates the severe consequences if we don’t all take our responsibilities seriously. I believe the course bridges the knowledge gap for those people entering the industry and also for people working in office based roles for those organisations who operate in this high hazard industry. I should also congratulate our very own Regan Redpath for being the very first person to pass the course.”

Compliance or Catastrophe? The Shocking Truth About Fake ATEX Fans


Compliance isn’t optional—it’s the difference between safety and catastrophe

A critical safety alert has been issued by the EU Safety Gate (Alert A12/01977/24) regarding the CHERUBIM BCFT-300 industrial fans falsely marketed as ATEX-certified for use in explosive atmospheres. These fans, sold via atex-supplies.com, lack essential safety features and could trigger catastrophic explosions in environments with flammable gases or dust.

If your company relies on ATEX, UKEX, or IECEx equipment, this guide could save lives—and prove why cutting corners on compliance is a deadly mistake.

For full details, see the EU Safety Gate Report.


KEY DETAILS

The CHERUBIM BCFT-300 (Batch 11.2024) is a 110VAC explosion-proof fan sold on atex-supplies.com. Despite being marketed for Zones 1/2/21/22, its unsafe design risks causing fatal explosions in flammable atmospheres.

Specification Details Compliance Status Risk Assessment
Product Name CHERUBIM BCFT-300 Portable Explosion Proof Fan Fully Non-Compliant Extreme Hazard
Batch Number 11.2024 Recalled 18/03/2025 Active recall in progress
Technical Specs 110VAC, 190mm blade, 2800r/min, 3300m³/h Untested full assembly Unverified mechanical safety
Certification Claims ATEX Zones 1,2,21,22 Failed Directive 2014/34/EU Fraudulent certification
Sales Channel atex-supplies.com Website under investigation Unauthorised distributor
Country of Origin China No valid EU type-examination Unapproved manufacturing standards
Hazard Type Ignition source in explosive atmospheres Confirmed by EU authorities Can cause fatal explosions
Regulatory Actions • EU-wide ban
• Mandatory recall
• Market withdrawal
Effective since 18/03/2025 Criminal penalties for non-compliance

Why This Matters More Than Ever

The CHERUBIM BCFT-300 fan was sold online via atex-supplies.com, claiming to be safe for Zones 1, 2, 21, and 22—yet it lacked genuine certification and could trigger explosions. This is part of a growing trend:

  • Falsified ATEX/IECEx certificates are being used to sell unsafe equipment.

  • Unregulated online marketplaces are flooded with hazardous products.

  • Cost-driven procurement leads to deadly compromises in safety.


Dangerous Industrial FanIndustry Warning: Rise of Counterfeit ATEX Equipment

Recent reports highlight a surge in fraudulent ATEX-certified products entering the market, including fake fans, lighting, and sensors. These products often

  • Use copied certification numbers from legitimate equipment.
  • Feature altered labels to mimic genuine compliance.
  • Lack proper testing for explosive atmospheres.

Stay Safe: Trust Only Verified ATEX Solutions

  • Never compromise on compliance—explosion-proof equipment saves lives.
  • Share this alert to raise awareness in your network.

How to Protect Your Workforce

  1. Demand Full Certification

    • Verify both electrical AND mechanical compliance

    • Check for BS EN 14986 on fans

    • Confirm ISO 80079 standards are met

  2. Validate Through Official Channels

    • Cross-check certificates in EU NANDO database

    • Contact notified bodies directly

  3. Beware of Red Flags

    • Prices significantly below market

    • Vague or incomplete documentation

    • Sellers avoiding technical questions

  4. Report Suspicious Products

    • EU Safety Gate for European alerts

    • UK Trading Standards for British market


Industry Leaders in the Fight Against Fake ATEX Equipment

A concerning number of ATEX-certified products currently available do not meet essential safety standards. While some components within these products may carry individual certifications, the complete assemblies often lack proper testing and compliance.

Key Concerns:

  • Products marketed as ATEX-certified without meeting BS EN 14986:2017 requirements for mechanical safety

  • Incomplete compliance with ISO 80079-36 and -37 standards

  • Certificates that only validate electrical components, not full assemblies

  • Genuine risk of ignition when used in explosive atmospheres

The lower cost of non-compliant equipment represents a false economy, as these products may fail dangerously in hazardous environments. Responsible procurement requires thorough verification of all relevant certifications before purchase and use.

Hazardous Area Explosive Atmospheres

Hazardous Area Explosive Atmospheres


How to Identify Fake ATEX-Certified Equipment: 5 Expert-Backed Tips

In environments where explosive atmospheres are a real risk, the use of compliant, genuine ATEX-certified equipment is critical—not only for operational safety but also for regulatory adherence. Unfortunately, fake ATEX products are increasingly entering global markets, putting lives, assets, and reputations at serious risk.

Below are five practical and experience-based checks you can carry out to verify the authenticity of ATEX-labelled equipment.


1. Scrutinise the Equipment Label for Accuracy

Start with the most accessible detail: the equipment label.

Ask yourself:

  • Does the text look professionally formatted?

  • Is all the expected information present and clearly spaced?

  • Is the ATEX coding (e.g., II 2 G Ex d IIC T6 Gb) accurate and legible?

  • Does the CE or UKCA marking look legitimate and correctly placed?

Poor-quality printing, missing details, and odd spacing are early warning signs. Falsely certified manufacturers often neglect small but crucial formatting standards.


2. Match the Certification to the Equipment

Always verify the ATEX certification against the product details. A genuine certificate should:

  • Clearly match the model and product type

  • Be issued by a recognised Notified Body (EU) or UK Approved Body

  • Include verifiable certificate numbers

Use public databases or reach out directly to the issuing body to cross-check certifications. Any mismatch could indicate a forgery.


3. Look for Dual Certification (ATEX and IECEx)

Many reputable manufacturers obtain dual certification—both ATEX and IECEx—to support global market access. While not mandatory, this adds credibility.

If a product claims both certifications:

  • Verify each independently

  • Ensure consistency across all certification numbers and product details

Absence of dual certification doesn’t necessarily mean a product is fake, but its presence, when valid, often reinforces authenticity.


4. Evaluate the Equipment’s Build Quality

Poor craftsmanship is often a hallmark of fake equipment.

Ask:

  • Does the build quality reflect its stated rating?

  • Are the materials and finishes consistent with hazardous area requirements?

  • Are there visible defects or signs of substandard manufacturing?

Inconsistent quality or a “cheap” feel should prompt further due diligence. If the physical product raises concerns, do not install it without rigorous verification.


5. Investigate the Manufacturer’s Legitimacy

Conduct a background check on the manufacturer:

  • Visit the company’s website. Does it reflect a legitimate operation that manufactures ATEX-compliant products?

  • Is there sufficient technical documentation, product data, or contact information?

  • Are there press releases, case studies, or recognisable industry affiliations?

  • Have they been referenced by trusted suppliers?

A lack of transparency or absence from trusted directories should raise suspicion. Always use multiple sources to confirm legitimacy.

The threat of fake ATEX equipment is real and growing. However, by applying these five practical checks, ranging from label scrutiny to manufacturer due diligence, you can mitigate the risks and maintain full compliance in explosive atmospheres.

Stay vigilant, stay compliant, and always verify.
