ISO 45001 certification, explained
ISO 45001 is the standard for occupational health and safety management systems. It helps an organization prevent work-related injury and ill health by finding hazards, controlling risks and involving workers in how safety is managed. It is relevant wherever people work on sites, with machinery, with contractors or at height. Certification is voluntary and is carried out by independent certification bodies.

Info. Showing a standard does not mean a partner holds scope for it. How matching works.
Who it may be relevant for
- Construction, oil and gas, manufacturing and utilities with higher-risk work
- Contractors and subcontractors working to client health and safety rules
- Facility management and logistics operators running many sites and vehicles
- Organizations that want safety managed as a system and not as a set of one-off rules
What it covers
- Hazard identification and risk assessment for routine and non-routine work
- Worker consultation and participation, including contractors and visitors
- Operational controls, emergency preparedness and incident investigation
- Setting objectives for improving health and safety performance
- Monitoring, internal audit and management review of the system
What it can help with
- A consistent way to find, rank and control hazards across sites and activities
- Better visibility of incidents and near misses and a route for corrective action
- Clearer responsibilities for managers, workers and contractors
- Evidence for clients who ask for a managed approach to safety during selection
What the pathway means
ISO 45001 is a certifiable management-system standard. An independent certification body audits your health and safety management system and decides on certification, following the usual route of inquiry, contract review, Stage 1, Stage 2, decision, surveillance audits and recertification. Certification does not mean the workplace is free of risk or compliant with every legal requirement. MIYAAR CONNECT does not audit or certify. We connect your inquiry with independent certification bodies.
Edition. ISO 45001:2018 is the published edition. ISO has a revision in development, and ISO's project page was reported to show a draft in enquiry stage with a new edition expected in 2027. Timing can change. Ask the certification body how a new edition would affect an audit you are planning. We do not state transition deadlines.
The typical process
Steps and timing vary by body and scope. This is the usual shape, not a promise.
- You and us
Your inquiry
You describe your needs and share the basics.
- Certification body
Application and contract review
The body reviews your scope, sites and size, then quotes.
- Certification body
Stage 1 audit
A readiness review of your management system documentation.
- Certification body
Stage 2 audit
An evaluation of how the system works in practice.
- This part is theirs
Certification decision
Made by the certification body, never by MIYAAR CONNECT.
- Certification body
Surveillance and recertification
Periodic surveillance audits, then recertification at the end of the cycle.
Where it is typically used
- A contractor aligning site induction, permit-to-work and contractor control across projects
- A manufacturer reviewing machine guarding, manual handling and chemical exposure risks
- A fleet and warehouse operator managing driver, loading and forklift risks together
What affects cost
- Number of employees
- Number of sites
- Complexity of what you do and its risks
- The inherent risk of the work, since high-hazard activities generally need more audit time
- Number of workers, shifts, sites and the share of work carried out by contractors
- Whether temporary or remote work locations must be sampled during the audit
- Whether auditors with experience of your specific sector are needed
What affects timing
- How established your hazard register, incident records and worker consultation already are
- Time to run and record emergency drills and internal audits before Stage 2
- The scheduling of site visits for multi-site or project-based work
- Any impact of the revision of the standard on how a certification body plans your audit
What to have ready
- A summary of the activities, sites and number of workers, including contractors
- A description of the main hazards and the controls you rely on, described not uploaded
- Recent incident and near-miss summary, in general terms at the inquiry stage
- Client or tender health and safety requirements that mention ISO 45001
- Existing management system certificates, if any
Accreditation and recognition
Certification carries weight according to the certification body and the scope. Accreditation bodies assess certification bodies for defined activities. Ask for the certificate number, the scope statement and the body's accreditation details, and confirm them with the accreditation body or through the Global Accreditation Cooperation Incorporated (Global ACI) arrangement, which took over from the IAF and ILAC on 1 January 2026. A certificate is not a substitute for meeting local workplace safety law, and whether a client accepts it is the client's decision.
Common questions
Is ISO 45001 the same as having a safety officer?
Does it replace OHSAS 18001?
Do contractors count?
Will certification prevent accidents?
