HAZARDOUS-AREA CLASSIFICATION
Hazardous Area Classification & Zoning Support in Nigeria
Hazardous area classification support in Nigeria for flammable gas, vapour and combustible dust: release-source registers, ventilation inputs, zone drawings and specialist review.
WHAT WE CAN SUPPORT
Defined scope.
Useful outcomes.
We connect process information and site measurements to a traceable classification basis, with uncertainties and technical responsibilities clearly recorded.
Flammable-material and combustible-dust information review
Release-source identification and evidence registers
Ventilation and site-layout assessment inputs
Gas and vapour Zone 0, 1 and 2 classification support
Dust Zone 20, 21 and 22 classification support
Zone drawings, extents and classification schedules
Equipment-to-zone evidence links and specialist review records
DELIVERY & COMPETENCE BOUNDARY
Right expertise.
Clear accountability.
Final hazardous-area classification, zone extents and technical sign-off remain subject to adequate site evidence and appropriately competent specialist review. This service does not constitute Ex-equipment certification or statutory approval.
OUR APPROACH
Rigorous enough to defend.
Practical enough to use.
Every assignment is scoped around the decision, risk and evidence involved. We are explicit about assumptions, limitations and where specialist or statutory approval remains necessary.
Gather the site basis
Review substances, process conditions, credible release points, ventilation, housekeeping and layout. Identify missing information before assigning zone extents.
Document the classification basis
Record the selected methodology, assumptions, release characteristics and supporting measurements so the classification can be reviewed.
Close gaps through competent review
Retain unresolved evidence gaps and submit classification records to the appointed competent specialist for review and technical sign-off.

FREQUENTLY ASKED QUESTIONS
Clear answers before the work begins.
What information is needed for hazardous-area classification?+
Typical inputs include material safety and flammability data, process conditions, credible release sources, ventilation, layout drawings, operating modes and dust housekeeping information. The required evidence is agreed for each site.
Which classification standards can be considered?+
IEC 60079-10-1 addresses explosive gas atmospheres and IEC 60079-10-2 addresses explosive dust atmospheres. The competent specialist confirms the applicable edition, jurisdiction and project methodology before use.
Does classification confirm that equipment is suitable?+
Classification defines the hazardous-area basis. Equipment suitability requires a separate review of the equipment identity, Ex marking, certification, installation conditions and applicable zone requirements.
Can hazardous-area assessment start without existing plant drawings?+
An initial scoping review can identify available information and missing measurements. The assignment may require a measured survey or verified layout before defensible zone drawings and extents can be completed. Any survey work and its limitations are agreed separately.
