Communication equipment ATEX enclosures are used to house communication equipment, and if your business works in an environment where flammable gases, vapours, mists, or combustible dusts are present, you may want to consider how you communicate. A standard walkie-talkie can’t always be used in hazardous environments as its electrical components can act as the ignition source.
In this case, an ATEX-certified radio can help. They’re designed and rated for use in specified potentially explosive atmospheres to enable communication while meeting explosion protection requirements. Industries such as Oil & Gas, Petrochemical, Chemicals, Mining, and Fuel Handling might require special communication equipment; however, is an intrinsically safe radio required by all companies? Well, no, it depends on the classification of your hazardous area, the substances you’re using, and the equipment you require.
What Is an ATEX Radio?
An ATEX-certified radio is a communication device that is certified for use within potentially explosive atmospheres, complying with the European ATEX directives.
The ATEX Directive 2014/34/EU is concerned with equipment and protective systems intended for use in potentially explosive atmospheres and their design and manufacturing. A potentially explosive atmosphere occurs when air is combined with a sufficient quantity of a material such as a flammable gas, vapour, mist or dust, and can be ignited under certain conditions.
ATEX certification does not simply mean that a radio is rugged, waterproof or durable. It indicates that the equipment has been assessed against specified explosion protection requirements for its intended application.
What Does Intrinsically Safe Mean?
An intrinsically safe walkie-talkie is designed to limit electrical and thermal energy so that the equipment does not provide enough energy to ignite a specified explosive atmosphere when operated within its certified conditions.
Intrinsic safety is one recognised explosion protection technique. It focuses on controlling the energy within electrical circuits, including energy that could potentially be released through sparks, heat or electrical faults.
This distinction is important when selecting communication equipment. A radio described as industrial, rugged or explosion-resistant should not automatically be considered intrinsically safe. Buyers should always verify the certification markings and permitted operating conditions.
Understanding ATEX Zones
Hazardous areas are classified according to the likelihood and duration of an explosive atmosphere.
For gases, vapours and mists, common zones include:
Zone 0: An explosive atmosphere is present continuously, for long periods or frequently.
Zone 1: An explosive atmosphere is likely to occur occasionally during normal operation.
Zone 2: An explosive atmosphere is not normally expected but may occur for a short period.
For combustible dust, equivalent classifications include Zone 20, Zone 21 and Zone 22.
The required equipment depends on the site’s classification, substances present and applicable protection requirements. Businesses should therefore identify the hazardous area before selecting a radio rather than choosing equipment based only on range, price or brand.
ATEX Radio for Oil and Gas Applications
An ATEX radio for oil and gas operations can be relevant in refineries, drilling facilities, offshore platforms, processing plants, fuel storage areas and other classified locations.
Workers in these environments often require instant communication for maintenance, coordination, emergency response and routine operations. A suitable radio can support communication while meeting the explosion protection requirements applicable to its intended location.
However, oil and gas facilities are not identical. Different areas within the same facility may have different classifications. A radio suitable for one location may not automatically be suitable for another.
Before selecting equipment, businesses should consider the hazardous zone, gas group, temperature classification, equipment category and protection method specified for the application.
ATEX Radio vs Standard Walkie-Talkie
A standard walkie-talkie may provide excellent communication performance while still being unsuitable for hazardous areas.
Its electrical circuits, battery, connectors or other components may not have been designed or assessed for use where explosive atmospheres can occur. Even a durable commercial radio should not be assumed to have explosion protection.
An ATEX-certified radio, on the other hand, is assessed for defined applications and protection requirements. Depending on the model, it may incorporate energy limiting components, controlled surface temperatures and other protective design features.
The key difference is therefore not simply durability. It is certified suitability for a defined hazardous environment.
When Do You Need an Intrinsically Safe Walkie-Talkie?
An intrinsically safe walkie-talkie may be required when personnel need communication equipment inside a classified hazardous area where flammable gases, vapours, mists or combustible dust could create an explosive atmosphere.
Common applications include:
- Oil and gas facilities
- Refineries and petrochemical plants
- Chemical processing facilities
- Fuel storage and handling areas
- Mining operations
- Certain manufacturing environments
- Facilities handling combustible dust
The final equipment decision should be based on the site’s hazardous-area assessment, applicable regulations and requirements established by the responsible safety or engineering team.
How to Choose an Ex-Rated Two-Way Radio in India
When searching for an Ex-rated two-way radio in India, price and communication range should not be the only considerations.
Check Certification
Review the complete certification marking, protection method, equipment category and other information provided by the manufacturer.
Confirm Zone Compatibility
Make sure the radio is certified for the hazardous zone where it will actually be used.
Check Gas or Dust Group
Different gases, vapours and combustible dusts have different ignition characteristics. The radio’s certification should match the relevant classification.
Review Temperature Class
Surface temperature can be important in hazardous environments. Confirm that the radio’s temperature classification is appropriate for the application.
Check Batteries and Accessories
Certification can apply to specific batteries, chargers, antennas, speaker microphones and other accessories. Use only combinations approved by the manufacturer.
Verify Documentation
Request relevant certification and product documentation before purchasing. The certification should correspond with the intended hazardous-area application.
Is ATEX Certification Enough for Every Hazardous Area?
No. ATEX certification does not automatically mean that a radio can be used in every explosive atmosphere.
The equipment must be suitable for the specific zone, substances, protection requirements and operating conditions. Certification markings provide important information about where and how the equipment can be used.
For international projects, IECEx certification may also be relevant. Businesses should compare the radio’s certification information with the hazardous-area documentation provided by the facility.
When there is uncertainty, the responsible safety, engineering or compliance team should confirm the required equipment classification before purchase.
Checklist Before Buying an ATEX-Certified Radio
Before purchasing a radio for a hazardous environment, check:
- Hazardous zone classification
- Gas, vapour, mist or dust hazard
- Required equipment category
- Equipment protection level
- Gas or dust group
- Temperature classification
- Approved batteries and accessories
- Manufacturer certification and documentation
These details can help businesses avoid selecting equipment that is unsuitable for the intended operating environment.
