Hazardous environments are no challenge for Intrinsically Safe devices

This is the latest of our occasional blog series focusing on our dedicated lone worker safety devices. This time we’re taking a closer look at our specialist devices from Twig and Ecom. They solve the problem of electronic communication in hazardous environments where there’s the danger of ignition or explosion. With Safe Hub operating on these intrinsically safe devices, you can protect your lone workers even in such extreme conditions.

What is intrinsic safety?

We know that many readers of our blogs are health and safety experts. But for the benefit of those who aren’t, we thought it was worth spelling out the meaning of the phrase ‘intrinsic safety’. In certain environments, there are dangers associated with electrical or thermal energy causing explosions. This is particularly true in environments where flammable gases or fuels are present.

Intrinsic safety is a protection technique designed to limit energy inputs, and electrical and thermal outputs. Intrinsic safety is applied to electrical equipment and wiring used in hazardous locations or where hazardous or flammable materials are used. Such explosion-proof devices are often also referred to as ‘rugged’.

Who verifies intrinsic safety?

Obviously, all such rugged equipment needs to be carefully tested to ensure that it is entirely safe in the most hazardous environments. Equipment is therefore certified by independent third-party agencies. In the UK, the most commonly applied standard is ATEX (Atmosphère Explosive). This is the commonly used acronym for the ATEX guidelines of the European Union

Meanwhile, IECEx is a system which provides an internationally accepted means of proving compliance with IEC standards. IEC standards are used in many national approval schemes and as such, IECEx certification can be used to support national compliance. Other international agencies that provide compliance standards include the Canadian Standards Association (CSA), Factory Mutual Research Corporation (FM) and the Mine Safety and Health Administration (MSHA).

Intrinsically safe but powerful devices

All of our intrinsically safe devices carry certifications from these agencies. At the same time, they’re top-of-the-range mobile phones, deploying GPS/GSM technology. And they provide excellent reception and coverage, which works well with Safe Hub and ensures the highest levels of lone worker safety.

Indeed, our recommended devices support the full range of Safe Hub features. In the event of an accident or dangerous situation, the lone worker can manually press the emergency button to trigger a Red Alert at the Alarm Receiving Centre (ARC). Meanwhile, the in-built 3D sensors will raise a reactive Worker Down alarm at the ARC. And the device’s screen allows the user to set intervals for our proactive Safe Check feature, and to access Group Alert and Safe Beacon messages.

Working in hazardous environment is hard enough for lone workers. If they have Safe Hub on one of our intrinsically safe devices, then they can have fewer safety concerns. And their health and safety managers can rest assured that they’re being looked after well.
