Beyond the Wiring: A Practical Guide to Hazardous Area Mechanical Inspections

Beyond the Wiring: A Practical Guide to Hazardous Area Mechanical Inspections

Wednesday 6 May

January 2026 marked a significant shift in industrial safety standards with the release of the 6th Edition of the ATEX Guidelines (2014/34/EU). While most businesses associate ATEX compliance with electrical systems, the updated guidance places a much sharper focus on the mechanical side of explosion protection. 

Equipment such as pumps, fans, and conveyors can become ignition sources through friction, sparking, or overheating which means mechanical inspections are every bit as critical as electrical ones.

• Overheating:  Bearings or seals reaching temperatures above the T-Class rating for the zone.
• Friction and impact: Metal-on-metal contact caused by misalignment or component wear.
• Static discharge: Non-conductive mechanical parts accumulate electrostatic charge.
• Mechanical failure: Breakdown of housings, guards, or structural components.

The Benefits of Hazardous Area Mechanical Inspections 

Reduced costs: Catching mechanical faults early prevents expensive emergency repairs. It can also lower insurance premiums by demonstrating a proactive maintenance regime and improve energy efficiency by ensuring couplings and drives are correctly aligned.

Legal compliance: Combining CompEx and HAMI inspections ensures full alignment with both ATEX and DSEAR regulations. You'll have audit-ready records, clear asset traceability, and protection against regulatory "Fees for Intervention."

Enhanced safety: Mechanical ignition sources are often silent until they cause serious harm. Running both HAMI and CompEx programmes ensures comprehensive protection for your workforce and your assets.

Optimised productivity: Planned inspections allow you to schedule downtime around your operations, rather than facing unplanned breakdowns at the worst possible moments. The result is greater reliability and more consistent output.

How SR Electrical Can Help

Our expert inspectors look beyond the wiring. We provide deep-dive mechanical assessments covering:

• Rotating machinery: Detailed checks on pumps, motors, and gearboxes
• Air movement systems: Inspecting fans, blowers, and conveyors for internal rubbing or material buildup
• Drive components: Assessing the condition of bearings, couplings, and mechanical belt drives
