Understanding Hazardous Area Lighting in Explosive Atmospheres

When working in environments with flammable gases, vapours, or dust, selecting the right lighting isn’t just about brightness—it’s about safety, compliance, and reliability. Hazardous area lighting solutions engineered to IECEx and Australian Standards ensure that your facility meets strict safety regulations while maintaining optimal performance.

1. What Defines a Hazardous Area?

Hazardous areas are classified by the presence and likelihood of explosive substances:

  • Zone 0: Continuous presence of explosive atmosphere (e.g., inside solvent tanks)

  • Zone 1: Occasional presence during normal operation (e.g., pump rooms)

  • Zone 2: Rare and short-term presence (e.g., general plant areas)

Accurate zoning dictates the type of equipment—particularly lighting fixtures—and their required protection methods.

2. IECEx Certification: The Global Benchmark

IECEx (International Electrotechnical Commission System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres) sets a unified standard recognized worldwide. Key benefits:

  • Global Acceptance: Eliminates the need for multiple national approvals.

  • Rigorous Testing: Verifies flameproof (“Ex d”), increased safety (“Ex e”), and pressurised enclosure (“Ex p”) protection methods.

  • Traceability: Full reporting on manufacturing, quality assurance, and testing processes.

By choosing IECEx-certified lights, you ensure a globally recognised level of safety and performance.

3. Australian Standards: AS/NZS 60079 Series

Australia and New Zealand have adopted the IEC 60079 series under the AS/NZS 60079 banner. Relevant parts include:

  • AS/NZS 60079.0: General requirements for explosive atmospheres.

  • AS/NZS 60079.1: Flameproof enclosures (“Ex d”).

  • AS/NZS 60079.2: Pressurised enclosures (“Ex p”).

  • AS/NZS 60079.7: Increased safety (“Ex e”).

  • AS/NZS 60079.10.0: Classification of zones for explosive gas atmospheres.

Compliance with these standards is mandatory for any lighting installed in classified zones across Australia.

4. Types of Hazardous Area Lighting Solutions

Apexio Industrial offers a comprehensive range of lighting options, tailored to your classified zone:

Protection Method Typical Use Cases Product Features
Ex d (Flameproof) Zone 1 & 2; chemical plants IP66/67, impact-resistant, high ambient temp.
Ex p (Pressurised) Zone 1; petrochemical control rooms Positive pressure barrier, maintenance-friendly.
Ex e (Increased Safety) Zone 2; offshore platforms No hot surfaces, sealed drivers, low ingress.
LED & High Intensity Discharge General illumination and task lighting Energy-efficient, long lifespan, low maintenance.


5. Key Benefits of Compliant Hazardous Area Lighting

  1. Enhanced Safety: Prevents ignition of explosive atmospheres.

  2. Regulatory Compliance: Meets mandatory AS/NZS and IECEx requirements.

  3. Operational Reliability: Built for harsh conditions—resistant to dust, moisture, and vibration.

  4. Energy Efficiency: LED options reduce power consumption and maintenance costs.

  5. Peace of Mind: Full traceability and quality assurance under IECEx certification.

6. Best Practices for Selection & Installation

  • Zone Verification: Conduct a formal classification study per AS/NZS 60079.10.0.

  • Protection Method: Match fixture protection (d, p, e) to zone requirements.

  • Ingress Protection (IP): Minimum IP66 for dust and water exclusion.

  • Temperature Rating: Ensure equipment surface temperatures stay below ignition points.

  • Maintenance Access: Opt for designs with hinged covers or quick-release fasteners.
