Oil refineries and petrochemical plants are among the most demanding environments for professional radio communication.

Operators, engineers, maintenance personnel, contractors, safety teams and security staff may work across:

• Process units
• Tank farms
• Pump houses
• Compressor areas
• Loading and unloading terminals
• Utility plants
• Control rooms
• Pipe racks
• Workshops
• Warehouses
• Fire stations
• Substations
• Wastewater-treatment areas
• Perimeter security posts

These teams can be separated by substantial distances, steel structures, vessels, pipes and reinforced buildings.

At the same time, some areas may contain flammable gases, vapours or other hazardous atmospheres.

That creates a requirement that does not exist in an ordinary warehouse or commercial property:

The radio itself must be appropriate for the hazardous area in which it will be used.

A conventional rugged walkie-talkie may provide excellent audio, long battery life and strong water resistance while still being completely unsuitable for a classified hazardous location.

This is why refinery buyers need to distinguish between terms such as:

• Rugged
• Waterproof
• IP67/IP68
• Intrinsically safe
• ATEX
• IECEx
• Hazardous-area certified

They are not interchangeable.

Electrosonic Technologies’ current catalogue includes professional digital radios specifically intended for hazardous-area applications, including the Motorola MOTOTRBO XiR P8600 Ex Series, which Electrosonic describes as ATEX-rated digital radios for hazardous areas. Motorola identifies the XiR P8608 Ex and XiR P8668 Ex as ATEX radios intended for environments containing potentially explosive gas and dust.

For refinery and petrochemical buyers, however, the radio model should come near the end of the selection process.

The first step is understanding where the radios will actually be used.

Why Refineries Still Depend on Two-Way Radios

Refineries operate through continuous coordination.

A process operator may observe an abnormal condition in the field.

The control room may need confirmation.

Maintenance may need to inspect equipment.

Electrical personnel may need to respond.

Safety personnel may need to establish a restricted area.

A supervisor may need updates from all of them.

Mobile phones can handle many individual conversations, but they are not designed specifically for rapid operational group communication.

With a professional radio system, a user can press push-to-talk and immediately contact:

• An operations group
• Maintenance
• Electrical personnel
• Security
• Emergency teams
• A supervisor

This makes radio particularly effective for short operational instructions such as:

“Mechanical maintenance, report to Pump Area 4.”

or:

“Operations supervisor, leak inspection required at Unit B.”

The goal is not to replace refinery procedures, alarms, public-address systems or safety systems.

Two-way radio provides an additional operational communication layer that connects mobile personnel throughout the facility.

Where Walkie-Talkies Are Used in Refineries and Petrochemical Plants

1. Process Operations

Field operators may move continuously between:

• Process vessels
• Pumps
• Heat exchangers
• Columns
• Compressors
• Valves
• Instrumentation
• Utility systems

They may need to communicate with the control room when:

• Checking equipment condition
• Confirming valve positions
• Investigating alarms
• Conducting field rounds
• Coordinating startup or shutdown activities
• Reporting abnormal noise, vibration or leakage

Instant group communication can reduce the time required to locate and contact the appropriate person.

---

2. Mechanical Maintenance

Mechanical teams may be responsible for:

• Pumps
• Compressors
• Rotating machinery
• Valves
• Heat exchangers
• Piping systems
• Mechanical seals
• Workshop repairs

Maintenance personnel may work across several units during the same shift.

A radio enables supervisors to dispatch technicians quickly and allows technicians to request additional personnel or equipment without leaving the work area.

---

3. Electrical and Instrumentation Teams

Electrical and instrumentation personnel may work around:

• Switchgear
• Motors
• Control panels
• Instrumentation
• Sensors
• Analysers
• Control valves
• Substations

Communication becomes particularly useful when technicians at different locations need to coordinate inspection or maintenance activities.

However, radios are communication tools—not substitutes for formal electrical isolation, permit-to-work, lockout/tagout or site safety procedures.

---

4. Tank Farms

Tank farms can cover large outdoor areas and may include classified hazardous zones.

Workers may be involved in:

• Inspection
• Transfer operations
• Maintenance
• Sampling
• Security
• Tank-level monitoring

This is exactly the type of environment where buyers must determine whether an ordinary industrial radio is permitted or whether certified hazardous-area equipment is required.

---

5. Loading and Unloading Terminals

Road-tanker, rail or product-loading areas may involve communication between:

• Operators
• Drivers
• Supervisors
• Security
• Control rooms
• Safety personnel

Because products being transferred may be flammable, equipment suitability should be determined according to the area’s formal hazardous-area classification.

---

6. Emergency Response and Fire Teams

Refineries usually maintain structured emergency-response procedures.

Radio communication may support:

• Fire teams
• Incident commanders
• Security
• Medical personnel
• Operations
• Emergency-control centres

For emergency communication, reliability and channel organisation are extremely important.

A large refinery should not discover during an incident that emergency personnel are competing with routine maintenance traffic for the same channel.

---

7. Security and Perimeter Operations

Not every part of a refinery is necessarily a hazardous classified area.

Security teams may operate around:

• Main gates
• Administrative buildings
• Perimeter roads
• Parking areas
• Security control rooms
• Warehouses

These positions may be able to use different radio configurations from employees entering hazardous process areas.

That distinction can significantly affect procurement cost.

The refinery does not necessarily need the same hazardous-area radio for every user.

---

The Most Important Buying Question: Where Will Each Radio Be Used?

A refinery should not begin procurement with:

“Which walkie-talkie should we buy?”

The better starting point is:

“Which areas will each category of employee enter?”

Consider three employees.

Employee A — Administrative Security

Works around the main office and visitor entrance.

Employee B — Maintenance Technician

Regularly works inside process units.

Employee C — Operations Supervisor

Moves between control rooms, process areas and loading zones.

These three employees may have completely different radio requirements.

The correct fleet may therefore contain:

• Standard professional radios for non-hazardous areas
• Hazardous-area radios for personnel entering classified areas
• Different accessories for each role

This can be safer and more economical than either extreme:

• Buying ordinary radios for everyone
• Buying the most expensive hazardous-area radio for everyone

---

What Does “Intrinsically Safe” Actually Mean?

Intrinsic safety is a protection concept used for electrical and electronic equipment intended for certain hazardous environments.

The basic principle is that the equipment is designed so that electrical and thermal energy is limited to levels intended to avoid ignition under the conditions covered by its certification.

This matters where an atmosphere may contain:

• Flammable gases
• Vapours
• Combustible dust
• Other ignition-sensitive hazards

A standard electronic device can contain:

• Battery contacts
• Switches
• Electrical circuits
• Connectors
• Internal components

In a hazardous atmosphere, equipment suitability cannot simply be assumed.

The plant must use equipment appropriate for the classified area and its applicable protection requirements.

---

ATEX Radios for Hazardous Areas

ATEX is a European hazardous-area framework commonly encountered when comparing industrial communication equipment.

Motorola states that its XiR P8600 Ex Series provides ATEX-rated communication for environments containing potentially explosive gas and dust, with the XiR P8608 Ex and XiR P8668 Ex forming part of the hazardous-area family.

Electrosonic’s live catalogue currently lists this same XiR P8600 Ex Series as an ATEX-rated professional digital-radio option for hazardous areas.

That makes hazardous industrial communication a genuine part of Electrosonic’s current product offering rather than merely an industry topic unrelated to its catalogue.

However, buyers must still check the complete certification marking and the exact location where the equipment will be used.

Do not make the purchasing decision from the single word:

“ATEX.”

---

ATEX vs IECEx

Industrial buyers may encounter both ATEX and IECEx certification references.

They are related to hazardous-area equipment but are different frameworks.

For procurement purposes, the important point is not to treat either name as a universal permission slip.

A refinery should verify:

• Hazardous-zone classification
• Gas or dust environment
• Equipment group/category or protection level
• Gas group where applicable
• Temperature class
• Complete equipment certification
• Local regulatory requirements
• Site engineering standards

Motorola identifies the XiR P8600 Ex family as ATEX/IECEx certified on its product information for the Ex models.

Whether a particular configuration is acceptable for a specific Indian refinery must still be confirmed against the site’s engineering and regulatory requirements.

---

Hazardous-Area Zones Matter

Not every location inside a refinery has the same risk classification.

Hazardous areas are classified according to factors such as the likelihood and duration of an explosive atmosphere being present.

This means a radio approved for one type of hazardous environment should not automatically be assumed suitable everywhere.

For example, procurement documentation should clearly identify:

• Which zones employees enter
• Which gas or vapour groups are applicable
• Required equipment protection
• Temperature limitations
• Site-specific certification requirements

PESO, India’s Petroleum and Explosives Safety Organisation, maintains requirements relating to protected electrical equipment used in hazardous petroleum environments. PESO’s published FAQ notes the use of protection concepts including flameproof, intrinsic-safety and encapsulated equipment for Zone 1 hazardous areas.

For refinery buyers, this reinforces an important principle:

Select the radio against the formal hazardous-area classification—not against a generic description such as “oil and gas radio.”

---

Do Not Assume ATEX Alone Automatically Approves a Radio for Every Indian Refinery

This distinction is important.

International certification is valuable evidence of how equipment has been designed and assessed.

But the plant also needs to satisfy:

• Applicable Indian regulations
• Site-specific hazardous-area requirements
• Internal engineering standards
• Equipment-approval requirements
• The exact classification of the proposed operating area

Therefore, procurement teams should involve the organisation’s:

• Electrical engineering department
• Instrumentation team
• HSE/safety department
• Hazardous-area specialist
• Compliance/procurement function

before approving radio use inside classified process areas.

For critical industrial deployments, this is much safer than relying solely on a reseller description or online product page.

---

IP67 or IP68 Does NOT Mean Intrinsically Safe

This is one of the most dangerous specification misunderstandings in industrial radio procurement.

A radio may be:

IP68

and still be inappropriate for a hazardous refinery area.

An IP rating describes defined protection against the ingress of:

• Solid particles
• Water

Intrinsic-safety or hazardous-area certification addresses a different risk:

whether the electrical equipment can be used under specified potentially explosive conditions.

These are completely separate properties.

A rugged waterproof radio is not automatically an intrinsically safe radio.

Electrosonic’s existing IP-rating guide makes the same distinction for oil, gas and hazardous industrial applications.

---

A Rugged Radio Is Not Necessarily a Hazardous-Area Radio

Product descriptions often use terms such as:

• Industrial grade
• Rugged
• Heavy duty
• Waterproof
• Military standard
• Professional

None of these terms alone establishes suitability for a classified hazardous atmosphere.

Before issuing a radio inside a hazardous refinery area, buyers should verify the actual certification.

If the required certification is not clearly documented, do not infer it from ruggedness.

---

Accessories Must Also Be Suitable for the Hazardous Environment

This is another area buyers frequently overlook.

Suppose a refinery purchases a properly certified hazardous-area radio and then connects an ordinary:

• Speaker microphone
• Headset
• Earpiece
• Battery
• PTT adapter

The complete equipment configuration may no longer meet the intended hazardous-area certification conditions.

Motorola’s documentation for the XiR P8600 Ex family specifically provides an ATEX accessory portfolio and indicates the importance of using appropriately certified accessories with the ATEX radio system.

This means procurement should consider the complete user kit, not only the handset.

For each role, verify:

• Radio
• Battery
• Antenna
• Speaker microphone
• Headset
• PTT accessory
• Carrying equipment where relevant

against manufacturer documentation.

---

Why Speaker Microphones Can Be Useful in Refineries

Field technicians frequently need both hands free for work.

A remote speaker microphone allows the radio to remain secured to the body while the microphone is positioned near the shoulder.

That can be useful when:

• Wearing gloves
• Carrying tools
• Inspecting machinery
• Climbing stairs
• Moving around process equipment

But in a hazardous area, the speaker microphone should form part of the approved radio/accessory configuration.

Do not buy generic accessories simply because the connector physically fits.

---

High-Noise Areas Need Different Audio Solutions

Refineries can be extremely noisy.

Employees may work close to:

• Compressors
• Pumps
• Turbines
• Blowers
• Steam systems
• Loading operations
• Heavy vehicles

Strong RF coverage does not guarantee useful communication.

A worker may receive the transmission perfectly but be unable to understand the words.

Buyers should therefore test:

• Speaker clarity
• Microphone performance
• Noise suppression
• Headset options
• Remote speaker microphones

under realistic plant noise.

Motorola’s hazardous-area communication material includes specialised ATEX audio accessories intended for demanding and noisy environments.

---

Digital Radio Can Help Organise Large Refinery Teams

Large refineries may have dozens or hundreds of radio users.

Putting every employee on one channel creates congestion.

A digital system can help organise communication into operational groups.

An example structure could be:

Talk Group	Typical Users
Process Operations	Field and console operators
Mechanical Maintenance	Mechanical technicians
Electrical & Instrumentation	Electrical and instrumentation personnel
Utilities	Utility-system teams
Security	Gates and patrol personnel
Fire & Emergency	Emergency-response personnel
Supervisors	Shift and department leadership

The exact configuration should reflect the organisation’s procedures.

Digital Mobile Radio does not automatically make a system safer, but it can provide more structured professional communication when designed correctly.

Electrosonic also maintains a separate DMR guide covering the broader advantages and architecture of professional digital-radio systems.

---

Emergency Communication Should Have a Defined Workflow

Some professional radios offer functions such as:

• Emergency buttons
• Man-down capabilities
• Lone-worker functions
• Location features
• Priority communication

Availability varies by radio, system and configuration.

These features can be useful in refinery operations, but only if the organisation defines what happens when they are activated.

For example:

An operator presses the emergency button.

Who receives the alert?

• Control room?
• Shift supervisor?
• Security?
• Emergency-response centre?

What information is displayed?

Who acknowledges it?

What operational procedure follows?

An emergency feature without an emergency-response workflow is simply an unused specification.

---

Radio Coverage Across Refineries

Refineries are challenging RF environments.

Coverage may be affected by:

• Steel process structures
• Storage tanks
• Pipe racks
• Concrete buildings
• Process vessels
• Equipment shelters
• Substations
• Tank farms
• Distance
• Terrain

A site may have excellent radio communication in the open and poor communication behind dense process infrastructure.

This is why advertised kilometre range should never be the primary buying criterion.

Electrosonic’s existing real-world range guide explains that radio range varies significantly with site conditions rather than remaining a fixed number.

---

Conduct a Site Survey Before a Large Deployment

A refinery trial should include the locations where employees genuinely need communication.

Typical test points might include:

• Main control room
• Process units
• Compressor area
• Tank farm
• Loading terminal
• Utility plant
• Workshops
• Substations
• Fire station
• Security control room
• Remote perimeter areas
• Administrative building

Test realistic communication paths such as:

Control room → process operator

Maintenance supervisor → tank farm technician

Fire station → process unit

Security control → remote gate

A few minutes of testing outside the administration building is not an adequate refinery radio assessment.

---

When Does a Refinery Need Repeaters?

A large facility may exceed reliable handheld-to-handheld coverage.

Repeaters can extend and strengthen a professional radio network.

A repeater receives a transmission and retransmits it from an appropriately planned location.

Repeaters may become useful when:

• Process structures create coverage gaps
• Separate operating units are far apart
• Tank farms cannot reliably reach the control area
• Indoor and outdoor teams need continuous communication
• Remote security positions lose contact
• Large areas exceed direct handheld coverage

Electrosonic currently lists professional repeater equipment alongside its portable-radio catalogue and has a separate guide covering repeater planning for large industrial sites.

Repeater locations, antennas and associated equipment should themselves be engineered appropriately for the site.

Do not assume that network infrastructure can be installed anywhere simply because the handhelds are hazardous-area rated.

---

Standard Radios and Hazardous-Area Radios Can Coexist

One of the most practical procurement approaches is to divide users by operating environment.

Consider:

Group 1 — Administrative Staff

Work only in offices.

Group 2 — Security Personnel

Mainly operate at non-hazardous perimeter positions.

Group 3 — Maintenance and Operations

Regularly enter classified process areas.

Group 4 — Emergency Teams

May need access across several hazardous locations.

The organisation may not need the same equipment for all four groups.

A properly designed fleet can provide compatible communication while allocating hazardous-area equipment only where it is actually required.

This reduces unnecessary cost without compromising safety.

Compatibility and system design should be confirmed before purchasing mixed fleets.

---

Battery Management Is Particularly Important in Continuous Plants

Refineries may operate 24 hours a day.

Radios may therefore be used across:

• Day shifts
• Evening shifts
• Night shifts

Battery planning needs to consider:

• Shift duration
• Radio duty cycle
• Battery age
• Charging time
• Spare batteries
• Shutdown periods
• Emergency reserve

Hazardous-area radios should only use batteries approved as part of the applicable radio configuration.

Substituting an unapproved battery simply because it fits physically can undermine the intended certified configuration.

---

Multi-Unit Charging for Large Radio Fleets

A refinery operating dozens of radios should have a controlled charging process.

A radio room may contain:

• Numbered handsets
• Approved batteries
• Multi-unit chargers
• Spare equipment
• Issue/return records

At shift handover, employees receive prepared radios.

This is usually easier to manage than distributing chargers throughout the plant.

A controlled equipment room also makes it easier to prevent incompatible accessories or batteries from entering a hazardous-area fleet.

---

Contractor Radios Need Special Attention

Refinery shutdowns and turnarounds may bring hundreds of temporary personnel onto the site.

Contractors may include:

• Mechanical teams
• Inspection specialists
• OEM engineers
• Electrical contractors
• Scaffold crews
• Cleaning teams
• Safety personnel

Some of these users may need radio communication.

The refinery should decide in advance:

• Who is permitted to carry radios?
• Which channels they use
• Whether contractor-owned radios are permitted
• Whether radios require programming
• Whether hazardous-area certification is required
• How radios are issued and returned

Allowing contractors to bring arbitrary programmable radios onto a controlled industrial site can create both safety and frequency-management problems.

---

Radio Licensing and Authorisation in India

Hazardous-area certification and radio-spectrum authorisation are two separate issues.

A radio may be correctly certified for an explosive atmosphere but still need to operate under an appropriate Indian telecommunications framework.

Conversely, a radio may be legally authorised to transmit on a particular frequency but still be physically unsuitable for a hazardous area.

India’s telecommunications framework changed substantially in 2026.

The Department of Telecommunications currently lists the:

• Telecommunications (Authorisation for Captive Telecommunication Services) Rules, 2026
• Radio Equipment Possession Authorisation Rules, 2026

under its current authorisation framework.

DoT’s Captive General Service framework covers establishment and operation of internal wireline or wireless networks for captive communication.

DoT also states that new Radio Equipment Possession Authorisation applications under the 2026 framework became available through its Authorisation Portal from 6 August 2026.

The practical message for refinery buyers is straightforward:

Do not rely on old licensing terminology or assume that a programmable radio can be operated on any frequency.

Confirm the current DoT/WPC requirements for the proposed network before deployment.

---

Hazardous-Area Approval and Spectrum Authorisation Solve Different Problems

This distinction deserves repeating because it is easy to confuse.

Hazardous-Area Certification

Addresses whether the equipment can be used under specified hazardous-atmosphere conditions.

Radio Authorisation

Addresses the legal operation and possession/use of radio equipment and spectrum/network requirements.

A refinery communication project may need to address both.

Passing one requirement does not automatically satisfy the other.

---

How Many Walkie-Talkies Does a Refinery Need?

Do not calculate the fleet from total employee headcount.

Instead, identify positions requiring simultaneous radio communication.

For example:

Role	Peak Radios
Process operators	24
Mechanical maintenance	10
Electrical & instrumentation	8
Utilities	6
Security	12
Emergency/fire team	8
Supervisors	6
Control-room positions	4
Peak Active Fleet	78

Then add:

• Shift-overlap requirements
• Spare units
• Contractor demand
• Shutdown/turnaround requirements
• Emergency reserve equipment

The next step is deciding how many of those users require hazardous-area radios.

A 90-radio refinery fleet may not necessarily require 90 ATEX or intrinsically safe radios.

The answer depends on where each user works.

---

A Practical Refinery Radio Fleet Example

Suppose a plant determines it needs 60 operational radios.

After analysing roles:

25 Employees

Regularly enter hazardous process areas.

20 Employees

Operate primarily in non-hazardous workshops and utility areas.

10 Employees

Work in security and perimeter positions.

5 Radios

Remain in fixed non-hazardous control or administrative locations.

The purchasing plan might therefore use different equipment classes while maintaining network compatibility.

The exact split should be based on the plant’s formal area classification and communication architecture.

This approach is more rational than choosing one handset for every employee.

---

Questions to Ask a Radio Supplier

A refinery buyer should ask more than:

“What is your best walkie-talkie?”

Ask:

1. Is this exact model certified for hazardous areas?
2. What is the complete certification marking?
3. Is it ATEX, IECEx or another certification?
4. Which hazardous zones does the certification cover?
5. Which gas or dust groups are included?
6. What temperature class applies?
7. Which battery is part of the certified configuration?
8. Which antennas are approved?
9. Which speaker microphones or headsets are approved?
10. Can the radios integrate with repeater infrastructure?
11. Can standard and Ex radios operate within the same communication system?
12. What coverage testing is recommended?
13. What current Indian radio authorisation is applicable?
14. What documentation is available for HSE and engineering review?

If the supplier cannot produce clear documentation for a safety-critical claim, treat that as a warning sign.

---

Questions to Ask Internally Before Requesting a Quotation

The supplier also needs accurate information from the refinery.

Prepare:

Site Information

• Total plant area
• Number of process units
• Tank farms
• Loading terminals
• Utility sections
• Workshops
• Remote facilities

Hazardous-Area Information

• Zone classifications
• Gas groups
• Temperature classes
• Dust hazards where applicable
• Internal equipment standards

Users

• Operations
• Maintenance
• Electrical & instrumentation
• Security
• Fire/emergency
• Contractors
• Management

Communication Requirements

• Number of talk groups
• Emergency communication
• Supervisory communication
• Individual calling
• Control-room requirements

Coverage

• Process areas
• Tank farms
• Workshops
• Control rooms
• Loading terminals
• Perimeter security
• Separate buildings

Accessories

• Speaker microphones
• Noise-control headsets
• PTT accessories
• Spare batteries
• Chargers

Infrastructure

• Direct radio coverage
• Repeaters
• Antennas
• Multiple sites
• PoC requirement for personnel outside the refinery

This information allows the radio system to be engineered around the facility instead of around a product brochure.

Common Mistakes When Buying Walkie-Talkies for Refineries

Mistake 1: Assuming a Rugged Radio Is Intrinsically Safe

It is not.

Verify the actual hazardous-area certification.

---

Mistake 2: Treating IP68 as Hazardous-Area Approval

IP ratings and intrinsic safety address completely different risks.

---

Mistake 3: Checking the Radio but Ignoring the Battery

Hazardous-area suitability can depend on the complete certified equipment configuration.

---

Mistake 4: Connecting an Ordinary Speaker Microphone to an Ex Radio

Accessories should be checked against the manufacturer’s approved hazardous-area configuration.

---

Mistake 5: Buying Hazardous-Area Radios for Every Employee Without Analysing Roles

Some employees may never enter classified areas.

Allocate equipment according to actual work zones.

---

Mistake 6: Buying Ordinary Radios for Everyone to Save Money

The opposite shortcut can create a serious safety and compliance problem.

---

Mistake 7: Buying Based on Advertised Range

Steel structures, tanks and process equipment can affect RF performance.

Conduct a site survey.

---

Mistake 8: Ignoring High-Noise Areas

Coverage is not useful if employees cannot understand the transmission.

Evaluate audio and accessories in the actual environment.

---

Mistake 9: Assuming ATEX Automatically Settles Every Indian Compliance Question

Verify the exact plant requirements, hazardous-area standards and applicable Indian approvals.

---

Mistake 10: Using Old Indian Radio Licensing Information

The telecommunications authorisation framework changed in 2026.

Check current DoT/WPC requirements.

---

Frequently Asked Questions

What is the best walkie-talkie for an oil refinery?

There is no universal best model.

The correct radio depends on hazardous-area classification, certification requirements, coverage, audio environment, network design and user role.

Personnel entering hazardous process areas may require specially certified equipment rather than ordinary industrial radios.

---

Does a refinery need intrinsically safe walkie-talkies?

Where the site’s hazardous-area classification requires appropriately protected equipment, an ordinary radio should not be used as a substitute.

The plant’s safety and engineering teams should determine the required protection and certification for each operating area.

---

Is an IP68 walkie-talkie intrinsically safe?

No.

IP68 relates to defined dust and water ingress protection.

Intrinsic safety relates to ignition risk in specified hazardous atmospheres.

A radio can be IP68 without being intrinsically safe.

---

What is an ATEX walkie-talkie?

An ATEX radio is equipment certified within the relevant ATEX hazardous-area framework for the conditions defined by its certification.

Buyers still need to examine the exact marking, zone suitability, gas/dust group and temperature classification.

---

Does Electrosonic offer hazardous-area radios?

Electrosonic’s current product catalogue lists the Motorola MOTOTRBO XiR P8600 Ex Series as ATEX-rated professional digital radios for hazardous areas, including XiR P8608 Ex and XiR P8668 Ex variants.

---

Are Motorola XiR P8600 Ex radios intended for refineries?

Motorola describes the XiR P8600 Ex Series as ATEX radios designed for environments containing potentially explosive gas and dust. Motorola’s hazardous-area accessory documentation specifically discusses demanding environments such as refineries.

The exact model/configuration still needs to be checked against the refinery’s specific hazardous-area classification and local requirements.

---

Do radio accessories also need certification?

In hazardous areas, accessories should be checked as part of the approved equipment configuration.

Using an arbitrary battery, speaker microphone or headset with a certified radio should not be assumed acceptable.

---

Can standard radios and intrinsically safe radios communicate together?

Potentially, yes, when they are compatible and correctly configured within the same radio system.

This can allow hazardous-area employees and non-hazardous-area personnel to communicate while using different handset types.

The exact network design should be confirmed before procurement.

---

Do refineries need repeaters?

Large sites frequently need coverage assessment.

Where direct handheld communication cannot reliably connect important operating areas, repeaters or other appropriately designed infrastructure may be required.

---

Is VHF or UHF better for refineries?

There is no universal answer.

Refineries contain both open areas and dense steel process structures.

Frequency selection should be based on actual site conditions, spectrum availability, network design and applicable regulations.

---

Can ordinary license-free walkie-talkies be used in a refinery?

They should not automatically be assumed suitable.

Even where a radio operates under an applicable licence-exempt framework, hazardous-area suitability is a separate question.

A radio that is legal from a spectrum perspective may still be unsafe for a classified process area.

---

Do refinery walkie-talkies require authorisation in India?

Radio requirements depend on the network, frequency, equipment and intended use.

India introduced a new telecommunications authorisation framework in 2026, so organisations should verify the current DoT/WPC requirements for their proposed system.

---

The Right Refinery Radio Is a Safety-System Decision, Not Just a Procurement Decision

For an office, selecting a walkie-talkie can be relatively straightforward.

For an oil refinery or petrochemical plant, the decision deserves a much more disciplined process.

The cheapest handset should not determine the outcome.

Neither should the radio with the longest advertised range or the highest IP rating.

Start with the facility.

Identify:

• Hazardous and non-hazardous areas
• Formal zone classifications
• Which employees enter each area
• Communication paths
• Noise conditions
• Coverage requirements
• Shift structure
• Emergency workflows
• Approved accessories
• Regulatory requirements

Then design the fleet.

For some employees, a standard professional digital radio may be entirely appropriate.

For personnel entering classified hazardous areas, the plant may need specialised ATEX/IECEx or otherwise appropriately approved hazardous-area equipment.

For large facilities, repeater infrastructure may be necessary.

For employees moving between several geographically separated facilities, PoC or another wide-area solution may complement the local plant radio system.

Most importantly, buyers should evaluate the complete certified system:

• Radio
• Battery
• Antenna
• Audio accessory
• Charger
• Network infrastructure
• Programming
• Regulatory framework

rather than evaluating the handheld in isolation.

Electrosonic Technologies’ live catalogue confirms that the company currently caters to hazardous industrial communication requirements with professional digital radios including the Motorola MOTOTRBO XiR P8600 Ex Series, alongside conventional digital radios, repeaters, PoC/LTE systems and accessories.

For refineries, petrochemical plants and other hazardous industrial facilities planning a new radio fleet, the most useful starting point is to provide the supplier with the site’s hazardous-area classifications, user roles, coverage map, shift requirements and required communication groups.

That allows the proposed communication system to be matched to the actual safety and operating environment rather than simply to a radio specification sheet.
