Frequently asked questions about explosion protection
Can smartphones with built-in batteries be taken into the hazardous area?
The answer is "no". A smartphone is a device according to the ATEX directive and requires approval. Devices without approval, regardless of whether they have a built-in battery, may not be taken into areas with explosive atmospheres.
The reason for this is that mobile phones generate electromagnetic fields that can, for instance, heat up small metal components. This means that there is a risk of these components becoming a source of ignition. The EN 60079-14 standard specifies the peak power up to which the electromagnetic field generated by a smartphone is considered not to be a source of ignition.
Mobile phone cases also pose a potential hazard. These are often made of plastic which can become electrostatically charged. This can cause electrostatic discharge, meaning that the mobile phone case becomes a potential source of ignition.
