EEHA Services for Defence | Hazardous Area Compliance

Hazardous Area Electrical Compliance for Defence Infrastructure

Defence environments often contain high-risk hazardous areas where explosive atmospheres may be present, including fuel storage, explosive ordnance facilities, and chemical handling zones.

In these environments, ignition sources are not always obvious, creating unseen risks to personnel, infrastructure, and mission-critical operations.

Inlex provides specialist EEHA (Electrical Equipment in Hazardous Areas) services to help Defence organisations identify risks, maintain compliance, and ensure safe operation in explosive atmospheres.

Hazardous area risks in defence environments

Defence facilities frequently operate with:

• Flammable fuels and vapours
• Explosive ordnance and storage systems
• Chemical processing and handling areas
• Legacy infrastructure not aligned with current standards

In many cases, electrical equipment installed in these environments pre-dates modern hazardous area standards, increasing the risk of non-compliance and potential ignition.

Improving hazardous area compliance

Effective control of ignition risk requires:

• Accurate hazardous area classification
• Correct selection of Ex-certified electrical equipment
• Installation in accordance with AS/NZS (IEC) 60079-14
• Ongoing inspection and maintenance aligned with AS/NZS (IEC) 60079-17

We work closely with Defence maintenance teams to:

• Raise awareness of regulatory requirements
• Identify compliance gaps
• Implement structured inspection and maintenance programmes

Ensuring long-term safety and compliance.
