Why do explosive atmospheres require specialist equipment?

Many types of electrical equipment can emit a spark under normal operating parameters, and in many environments, this is not a cause for concern. However, this spark could ignite flammable dust or gases within an explosive atmosphere, threatening the safety and even the lives of the workers within it.

This is an unacceptable safety risk so to mitigate against it, EU Directives dictate that only specialist equipment that conforms to the most stringent safety standards may be used within these environments to preserve worker safety and enhance safety outcomes.

What is the difference between an ATEX and non-ATEX Radio?

ATEX radios are often referred to as “intrinsically safe radios” as they are specifically engineered to limit their thermal and electrical energy output, ensuring that their use will not jeopardise worker safety when used within explosive atmospheres.

ATEX radios are identified by an “Ex” marking, which confirms that they comply with the stringent regulations issued by the European Union’s ATEX Directive. They are made from robust materials with non-sparking qualities and deliver a strict thermal performance.

They usually conform to the IP67 ingress protection rating and have integrated GPS so that the location of workers can be precisely monitored in case extraction or rescue is necessary. Some also offer a lone worker or person down alarm, which can be triggered under certain circumstances, again enhancing safety outcomes.

Conversely, non-ATEX radios do not need to comply with the ATEX Directive and, therefore, can be made from less robust and thermally protected materials. They do not require embedded GPS or alarms and are not designed for use in explosive atmospheres.

Why should you choose an ATEX Radio?

ATEX digital two way radios are more costly than the non-ATEX equivalent because they offer greater functionality and conform to stricter safety specifications. Therefore, the main reason to choose an ATEX radio is because you will use it in an environment in which it would be unsafe to use a non-ATEX radio.

You should choose an ATEX radio if you or members of your workforce will have a need to communicate with others while working in a hazardous environment, such as underground, within a silo or in an enclosed area containing chemicals. You should carefully assess the work environment and consider what PPE your workers will be wearing to ensure that you select an appropriate radio that they will be able to easily carry and operate within the intended environment.

You should choose an ATEX radio if worker safety is your overriding priority, as these radios will ensure continuous radio contact while also minimising the risk of your communication equipment overheating or igniting flammable dust or gases.

What industries commonly rely on ATEX Radios?

ATEX portable radios are commonly used by a number of industry sectors, including the oil and gas industry, mining and chemical manufacturing. Essentially, any sector that requires its workers to operate in an environment that may be hazardous to their health or be subject to environmental hazards that cannot be easily mitigated, should equip their workers with ATEX radios to enhance their safety outcomes and comply with their legal and ethical responsibilities.

What benefits do intrinsically safe radios offer?

ATEX portable radios, or intrinsically safe radios, offer numerous benefits to workers who are required to perform their duties in hazardous environments and explosive atmospheres.

Firstly, they provide excellent audio quality, allowing workers to remain in contact with each other and with outside agencies as needed. Their robust design ensures that they operate reliably, even if dropped or knocked.

ATEX digital two way radios usually offer a wide range of frequency bands, enabling workers to tune in to specific channels based upon their work directive and environment. Supervisors may also monitor communications across numerous different channels, increasing operational efficiency and enhancing productivity. Large buttons and visual displays increase ease of use, particularly for workers wearing bulky PPE, which can make operating fiddly equipment a challenge.

IP67 ingress protection means that ATEX radios will be unaffected by moisture and dust, enabling them to work effectively, regardless as to the environmental hazards encountered during use. This makes them a versatile and obvious choice for workers across a wide range of industry sectors, from off-shore oil rigs to mining and beyond.

Integrated GPS and alarms, such as lone worker and person down alarms, mean that reporting incidents and rescuing injured or incapacitated workers is simplified, which not only improves safety outcomes but aids in incident reporting. ATEX portable radios are lightweight and equipped with efficient power management systems, meaning that they will last an entire shift without the risk of battery failure. Not only does this reduce the initial cost of purchase but it also minimises the weight that workers are required to bear, as spare radios are typically not required.

ATEX portable radios are easy to use with user-friendly interfaces so workers do not usually need specific training in order to operate them effectively. This reduces the training burden placed upon organisations while also delivering long-term cost savings.

Finally, choosing ATEX portable radios for use by workers operating in explosive atmospheres ensures that your business is compliant with local laws and international regulations. It demonstrates your commitment to worker safety, reduces the risk of litigation and can attract new workers while reducing employee turnover rates.

What manufacturers produce ATEX Directive-compliant radios?

There is a wide range of radio manufacturers producing intrinsically safe radios, including Motorola, Kenwood and Hytera, amongst others.
