Hazardous Area Classification
Clear classification. Safer electrical design.
Hazardous area assessment.
Practical design decisions.
Hazardous Area Classification support for projects and operating facilities, integrating process release scenarios, ventilation, equipment layout and ignition-risk considerations into a clear classification basis for design.
Classification basis
Define substances, process conditions, potential release sources, ventilation assumptions and applicable classification methodology.
Release source assessment
Identify credible release sources and assess grade, frequency and duration of release under normal and abnormal conditions.
Zone classification
Determine hazardous zones and extents based on release behaviour, ventilation and equipment arrangement.
Design integration
Translate the classification into practical equipment-selection, layout, electrical and inspection requirements.
From release source
to classified area.
The classification is developed from the process design rather than as an isolated electrical exercise, so the final zones are technically defensible and usable by layout, electrical, operations and maintenance teams.
Confirm fluids, operating conditions, release mechanisms, equipment arrangement and ventilation assumptions.
Review valves, flanges, vents, drains, seals and other potential sources to determine credible release characteristics.
Establish zone type and extent, including the influence of ventilation, congestion and local geometry.
Document the classification basis and translate it into equipment, layout, inspection and operating requirements.
Need a hazardous area classification review?
Send the process conditions, layout information and project stage. We can help establish or review the hazardous area classification basis and zone extents.
