ATEX, UL & IECEx Guide

Please note that Radio Industries Australia Pty Ltd does not classify or take responsibility for the Hazardous Location Settings mentioned in this page, this is just a guide. Please consult your Safety Department for your exact Hazardous Location requirements.

What is Intrinsically Safe?

Intrinsically safe is a term used to describe a collection of devices and equipment that meet the requirements set out by the certification body (ATEX, UL or IECEx) to determine that device or equipment’s safety when used in a hazardous environment.

What is a Hazardous Environment?

A Hazardous Environment is an area where fumes, dust, gas or vapour may cause a fire or explosion when an ignition source is used in the area. For example, you may see a ‘No Naked Flames’ sign in your petrol station when filling up your car, this is because the area is classed as a Hazardous Environment. People who use devices like Two-Way Radios in these environments need to ensure that the device itself complies with the standard set for that particular zone. Often a safety officer will have this information to hand and be able to direct you as to what type of equipment you need for different areas of your plant.

What is the difference between ATEX, UL and IECEx?

The difference between these three is the testing/classification body.

Each rating is created by a recognised standards body with ATEX Being European, UL being American and IECEx often used for international standards. Your company may choose a specific standard to base decisions from.

ATEX Explained

Download the CML ATEX/IECEx Guide HERE - https://www.cmlex.com/wp-content/uploads/hazardous-area-guide.pdf

An ATEX Label will tell you exactly where the equipment can be used based on the Equipment classification and Zones specified. All of the numbers and letters on the label correspond to the level of protection offered and in what environments the equipment can be used. Please consult your safety supervisor for the correct equipment class you require based on the zones you are subject to.

ATEX Equipment is classified by Group, Type of protection, Gas/Dust Group, Temperature class and equipment protection level.

Areas where ATEX must be used is classified by Zones. Each Zone is for a particular Hazardous Environment. Each Zone is explained below. You will then need to use equipment suitable and certified for use the Zone.

ATEX Zones

Combustible Gas & Vapour

Gas Zone Description ATEX Category EPL Required Protection
Methane Mines with methane and dust. Equipment remains energised in explosive atmosphere. M1 Ma Two Faults
Methane Mines with methane and dust. Equipment is de-energised in explosive atmosphere. M2 Mb Severe Normal Operation
Zone 0 A place in which an explosive atmosphere consisting of a mixture with air of dangerous substances in the form of gas, vapor or mist is present continuously or for long periods or frequently. 1G Ga Two Faults
Zone 1 A place in which an explosive atmosphere consisting of a mixture with air of dangerous substances in the form of gas, vapor or mist is likely to occur in normal operation occasionally. 2G Gb One Fault
Zone 2 A place in which an explosive atmosphere consisting of a mixture with air of dangerous substances in the form of gas, vapor or mist is not likely to occur in normal operation but, if it does occur, will persist for a short period only. 3G Gc Normal Operation

Combustible Dust & Fibres

Dust Zone Description ATEX Category EPL Required Protection
Zone 20 A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is present continuously, or for long periods or frequently. 1D Da Two Faults
Zone 21 A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally. 2D Db One Fault
Zone 22 A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is not likely to occur in normal operation but, if it does occur, will persist for a short period only. 3D Dc Normal Operation

Equipment Groups

Equipment Group Description
Group I

Electrical equipment intender for use in mines susceptible to fire damp

Group II A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally.
Group III Electrical equipment intended for use in explosive dust atmospheres

IECEx Explained

IECEx is very similar to ATEX however some of the definitions for the protection offered do differ so keep that in mind.

Download the CML ATEX/IECEx Guide HERE - https://www.cmlex.com/wp-content/uploads/hazardous-area-guide.pdf

UL Explained

UL is classified by Divisions and Classes. The classes define the substance whilst the Division defines the operating conditions. The classes are also split into subgroups to determine specific and/or equivalent substances.

Classes
  • Class I – Flammable Gases, Vapours or Liquids

    • Group A - Acetylene and equivalent gas groups​

    • Group B - Hydrogen and equivalent gas groups ​

    • Group C - Ethylene and equivalent gas groups ​

    • Group D - Methane, and equivalent gas groups 

  • Class II – Combustible Dust

    • Group E - Conductive dust (mechanical – factories, recyclers)

    • Group F - Combustible carbon dust (charcoal & coke dust) - above ground only​

    • Group G - Grain dust

  • Class III – Ignitable Fibres and Flyings (No Subgroups)
Divisions

Division 1 - Locations where ignitable gas/vapor/liquid/dust are present continuously or some of the time under normal operating conditions. 

Division 2 - Locations where ignitable gas/vapor/liquid/dust are not likely to exist under normal operating conditions.

Based on the above a rating of ‘Class I, Div 1, Group C, D’ would be given to an environment where Ethylene and Methane are expected to be present continuously

Frequently Asked Questions

How Far Can Two-Way Radios Reach?

Two-way radios operate using line-of-sight communication, which means buildings, hills, steel structures and other obstacles can affect range. Actual distance depends on the environment, radio power, antenna type and system setup.

Typical examples:

  • Small offices or retail: hundreds of metres
  • Warehouses and construction sites: 1–3 km
  • Open outdoor areas: several kilometres
  • Repeaters or Push-to-Talk over Cellular systems: Australia-wide coverage

If coverage is critical, Radio Industries can help design the right communication solution.

What Channels Can I Use?

In Australia, radios can operate on:

  • UHF CB channels (1–80) – public shared channels available for general use
  • Private licensed frequencies – dedicated channels licensed through ACMA for business use
  • Digital radio systems – for improved audio and advanced features
  • Push-to-Talk over Cellular (PoC) – communication over mobile networks and Wi-Fi

The right option depends on your application and operating environment.

Which Radio Is Best?

There is no one-size-fits-all answer. The best radio depends on:

  • Your industry
  • Required coverage area
  • Team size
  • Indoor or outdoor use
  • Safety requirements
  • Noise levels
  • Whether you require UHF CB, licensed channels or nationwide communication

A warehouse team may need digital radios, while transport fleets may benefit from Push-to-Talk over Cellular systems.

Do I Need A Private Frequency?

Not always. UHF CB channels are suitable for many general communication applications.

However, private frequencies are recommended where:

  • Communication is safety critical
  • Teams operate around cranes or major construction projects
  • Privacy is important
  • Multiple users share the same location
  • Interference must be minimised

Dedicated channels help improve reliability and reduce unwanted outside traffic.

What Is The Difference Between a Two-Way Radio, Walkie Talkie and Handy Talkie?

They generally refer to the same type of device.

In professional environments, Two-Way Radio is the preferred industry term. “Walkie Talkie” and “Handy Talkie” are commonly used for recreational or consumer products.

What Is The Difference Between Analogue and Digital Radios?

Analogue radios use traditional radio technology and are often suitable for basic communication requirements.

Digital radios provide:

  • Clearer audio quality
  • Better noise reduction
  • Longer battery life
  • Improved coverage performance
  • Advanced features such as private calling and GPS

Digital systems are commonly used by businesses requiring higher performance and reliability.

What Is Push-to-Talk Over Cellular (PoC)?

Push-to-Talk over Cellular works like a two-way radio but uses 4G, 5G and Wi-Fi networks instead of traditional radio signals.

Benefits include:

  • Australia-wide coverage
  • GPS tracking
  • Group communication
  • No repeater infrastructure required
  • Easy expansion across multiple locations

This solution is ideal for transport, security, events and nationwide operations.

Can Two-Way Radios Work Australia-Wide?

Traditional radios have distance limitations unless repeaters are used.

For nationwide communication, many businesses choose Push-to-Talk over Cellular systems, which operate across mobile networks and Wi-Fi.

Can Different Brands Of Radios Communicate Together?

Sometimes.

Compatibility depends on:

  • Frequency settings
  • Channel programming
  • Analogue or digital mode
  • Signalling protocols (IDAS, DMR, NXDN, TETRA, P25)
  • System configuration (Capacity Plus, Capacity Max, P25)

Even radios from different manufacturers may communicate if correctly programmed.

Do Radios Need Programming Before Use?

Many professional radios require setup before deployment.

Programming may include:

  • Channel configuration
  • Private frequencies
  • User groups
  • Emergency functions
  • Scan lists
  • Button customisation

Radio Industries can pre-program and configure systems before dispatch.

Can I Use Headsets With Two-Way Radios?

Yes. Many industries use headsets and accessories to improve communication and safety.

Popular options include:

These are commonly used in construction, security, industrial sites and events.

Are Two-Way Radios Waterproof?

This depends on the model.

Many commercial radios include protection ratings such as:

  • IP54 – Protected against limited dust ingress and resistant to water splashes from any direction. Suitable for indoor use, retail, warehouses and light outdoor environments.
  • IP67 – Fully protected against dust and can withstand temporary immersion in water up to 1 metre for up to 30 minutes. Commonly used on construction sites, security operations and harsh environments.
  • IP68 – Fully dustproof with enhanced water protection beyond IP67 standards. Exact depth and duration vary by manufacturer, but these radios are designed for more demanding environments with heavy dust, rain and exposure to water.

The right rating depends on your work environment.

Can Radios Be Used On Construction Sites?

Yes. Two-way radios are widely used across construction projects for coordination, safety and productivity.

Many sites use:

  • Rugged digital radios
  • Hearing protection headsets
  • Vehicle-mounted radios
  • Dedicated licensed frequencies

Radio Industries can recommend systems suited to site conditions and OH&S requirements.

Do You Offer Repairs And Ongoing Support?

Yes.
