Maintenance of ATEX-certified portable devices – What operators need to be aware of

⚠ Why is it so important to maintain ATEX-certified equipment?

An ATEX-certified device can only be operated safely if it remains in the intended condition.

Incorrect maintenance or improper repairs can:

🔴 Invalidate the ATEX certification

🔴 Jeopardize safety – it can become an ignition source

🔴 Legal consequences for the operator.

Therefore, companies are obliged to ensure regular inspections and maintenance.

✅ 1️⃣ Maintenance & Inspection – Regulations & Responsibilities for Operators

The ATEX directives (2014/34/EU) and the Industrial Safety Regulation (BetrSichV) stipulate that ATEX devices:

✔ Must be regularly checked

✔ May only be used in a safe condition

✔ Maintenance may only be performed by trained personnel

When and how often does it need to be checked?

📌 Daily visual inspection by the user:

• Are there visible damages to the case, display, or buttons?
• Is the antenna or the camera in perfect condition?
• Is the device functioning normally or are there error messages?

📌 Regular technical inspection by qualified personnel:

• Depending on the manufacturer's recommendations and the operational risk assessment (often annually)
• Review of electrical safety and all protective mechanisms
• Check battery status and charging behavior

📌 Additional review after special events:

• If the device has fallen or has been subjected to heavy stress
• If it came into contact with liquids or chemicals
• If malfunctions or warning indications occur

❗ Important:

All maintenance measures must be documented to demonstrate compliance with the ATEX requirements.

✅ 2️⃣ Cleaning & Storage – But not in the ATEX Zone!

ATEX devices must never be maintained or cleaned in the explosion hazard zone.

🔴 Why?

• Any maintenance or cleaning can stir up dust or unintentionally cause sparks.
• A opened or damaged device could become a source of ignition.
• Most cleaning agents are not approved for use in Ex zones.

✔ Proper Cleaning & Storage:

✅ Cleaning takes place outside the ATEX zone, in a safe environment.

✅ Do not use aggressive solvents – they could damage seals or housings.

✅ Use a damp cloth with manufacturer-approved cleaning agent.

✅ Carefully remove dust deposits – without static charge.

✅ Store devices safely, not in damp or overheated areas.

✅ Do not leave batteries on the charger permanently to avoid overcharging.

✅ 3️⃣ Only use approved batteries & accessories

🔋 ATEX devices may only be operated with the certified batteries and accessories listed in the certificate!

🔴 Why?

• Non-certified batteries can generate excessive voltage or temperature → risk of ignition!
• Inappropriate batteries can cause gas development or thermal runaway.
• Accessories such as chargers or headsets must also be ATEX certified.

✔ Solution:

Always use original batteries and accessories approved by the manufacturer!

✅ 4️⃣ Repairs & modifications are taboo (except by certified professionals!)

🚨 Attention: Operators are not allowed to make unauthorized repairs or modifications to ATEX devices!

🔴 What is not allowed?

• Do not open the device – any tampering may destroy the explosion protection function.
• Do not use unauthorized replacement parts – only original components are ATEX compliant.
• Do not install any software modifications or insecure firmware updates.

✔ Solution:

If a device is defective, it must be sent to a certified repair shop or the manufacturer for repair.

❗ Attention:

After each repair, the device must be rechecked and documented before it can be used again in ATEX zones.

✅ 5️⃣ Employee Training – Operator Obligation!

📢 Companies are required to train their employees in the use of ATEX devices.

🔴 Why?

• Improper use can become a source of ignition.
• Users must be able to recognize damage and know when a device needs to be replaced.
• Maintenance personnel must know the correct testing procedures.

✔ Solution:

Regular training on the following topics:

✅ How to identify damages and defects?

✅ What to do if a device becomes suspicious?

✅ Which batteries & chargers are allowed?

✅ How are ATEX devices properly cleaned and stored?

❗ Tip:

Training should be documented to demonstrate compliance with regulations.

🚀 Conclusion: Safe maintenance protects people & operations

ATEX-certified portable devices are essential for explosive environments – but only if they are properly maintained and handled!

🔹Maintenance and inspection are mandatory – only tested devices remain safe.

🔹 No cleaning or maintenance in the ATEX zone!

🔹 Only use certified batteries & accessories – experiments are taboo!

🔹 Unauthorized repairs are prohibited – only authorized service centers may open the device.

🔹 Employees must be trained – they are the first line of defense.

🚨 A poorly maintained ATEX device can become a deadly hazard – that’s why careful inspection and maintenance are essential!

➡ Focus on regular maintenance and trained staff – for maximum safety in explosion-prone areas!💡💪
