Workplace safety is a growing priority across Nigeria's high-risk industries — oil and
gas, construction, manufacturing, mining, and logistics — where occupational hazards
carry serious human, financial, and reputational consequences. The Federal Ministry of
Labour and Employment, the Nigerian Upstream Petroleum Regulatory Commission (NUPRC),
and sector-specific HSE frameworks are increasingly demanding evidence of structured
safety management. International clients, joint venture partners, and insurers similarly
require certified proof of effective occupational health and safety governance before
engaging Nigerian contractors and operators.
As an EGAC-accredited certification body, IEMA Standards Ltd delivers ISO 45001:2018
Occupational Health and Safety Management System (OHSMS) certification with full
international recognition through the IAF/GAC Multilateral Recognition Arrangement —
combining global audit rigour with practical understanding of Nigeria's high-risk
operating environments and labour regulatory landscape.

How we work
Our ISO 45001 certification process
01
Application & certification agreement
We review your organization's scope, sites, and operational risks, and formalise
the certification agreement and audit plan.
02
Gap analysis & readiness review (optional)
An optional pre-assessment identifies gaps in your existing OHSMS ahead of the
formal certification audit — reducing the risk of non-conformities.
03
Stage 1 audit — documentation review
Our auditors review your OHSMS documentation, risk registers, and safety policies
to confirm readiness for the on-site Stage 2 audit.
04
Stage 2 audit — on-site assessment
A comprehensive on-site audit of your facility, work practices, and safety
controls verifies effective implementation against ISO 45001:2018 requirements.
05
Certification decision & issuance
Following independent technical review, IEMA issues an EGAC-accredited ISO 45001:2018
certificate valid for three years, subject to surveillance audits.
06
Surveillance & recertification
Annual surveillance audits maintain your certified status, with full recertification
audit conducted at the end of each three-year cycle.
