Intrinsically Safe Mobile Devices and Safety Inspections Application

It is currently mandatory for safety inspectors to carry intrinsically safe devices when performing safety inspections in hazardous environments. Many worksites with flammable gases, vapours, or dust forbid the use of standard smartphones and tablets, as uncertified devices can pose an ignition risk in classified hazardous areas.

For organisations that want to take advantage of digital inspection technology in these environments, the solution is to pair inspection applications with devices that have been certified as intrinsically safe for the relevant hazard zone.

What is Intrinsic Safety?

Intrinsic safety is a protection method applicable to equipment operated in areas with flammable gases, vapours, liquids, or combustible dust. A certified intrinsically safe device is designed to prevent the release of sufficient electrical or thermal energy to cause ignition of flammable material under normal or fault conditions. This means that even in the event of device failure, the energy released cannot exceed the minimum ignition energy of the hazardous substance present.

This protection method keeps both the inspector and all those within the operating environment safe during an inspection. It is not simply a feature of the device but a design philosophy that governs the entire manufacturing and testing process of the equipment.

ATEX and IECEx Certification Standards

There are two primary regulatory frameworks that govern the certification of intrinsically safe mobile devices. Understanding the distinction is important for selecting the right certified device for your operating region:

• ATEX (Atmospheres Explosibles): The primary certification framework recognised across Europe. ATEX certification covers both the equipment itself and the workplace, providing a two-directive framework that governs how devices are manufactured and deployed in explosive atmospheres.
• IECEx (International Electrotechnical Commission Explosive): Recognised internationally, the IECEx scheme provides a globally harmonised approach to certification that is accepted in Australia, Asia, the Americas, and beyond. Many organisations operating in Australia or Asia-Pacific specify IECEx certified equipment.

Both certifications classify hazardous areas by zone, with Zone 0 being the most hazardous (where explosive atmospheres are continuously present) and Zone 2 being the least (where explosive atmospheres are unlikely under normal conditions but may occur in abnormal situations). Devices are certified for specific zones, and operators must verify that the device rating matches the zone classification of their worksite.

Digital Inspection on Intrinsically Safe Devices

The good news for organisations operating in hazardous areas is that there is now a broad range of certified intrinsically safe smartphones and tablets running modern operating systems. These devices can run the same digital inspection applications used on standard mobile hardware, bringing all the benefits of paperless inspection into environments where they were previously inaccessible.

Features such as photo capture, barcode scanning, speech-to-text data entry, offline reporting, and GPS timestamping are all available on certified devices. Inspectors in Zone 1 and Zone 2 areas can complete comprehensive digital checklists, capture photographic evidence of equipment condition, and sync completed reports to the central system when connectivity is available.

For organisations in the oil and gas, chemical, or mining sectors, investing in intrinsically safe certified devices and pairing them with a capable inspection management platform delivers the same operational benefits seen in non-hazardous environments: fewer errors, faster reporting, better compliance, and a more resilient safety culture.
