ISO 45001 Revision: What Philippine Organisations Should Do Now

Is a new version of ISO 45001 coming? The honest answer

Yes, a revision of ISO 45001 is in progress — but no new edition has been published, and there is no transition deadline of any kind. As of September 2026, ISO 45001:2018, together with its Amendment 1:2024 on climate action, remains the only edition of the occupational health and safety management standard you can implement and be certified against. ISO’s own listing confirms that ISO 45001:2018 “remains current,” while the revision project — ISO/DIS 45001, run by technical committee ISO/TC 283 — reached Draft International Standard stage in April 2026 and closed its DIS ballot on 9 September 2026 (stage 40.60, close of voting). ISO’s project page now indicates that the revised edition will replace ISO 45001:2018 in the first half of 2027; that is a target, not a committed publication date, and the text can still change before it is final.

That one paragraph should save you from the most expensive mistake in the Philippine ISO market right now: paying someone to “upgrade” you to a standard that does not exist. If a consultant or a so-called certification provider is pressuring your construction firm or manufacturing plant to buy an “ISO 45001:2026 transition package” or warning you that your 2018 certificate is “about to expire because of the new version,” they are selling fake urgency. No transition clock is running, because there is nothing yet to transition to.

What a serious contractor or manufacturer in the Philippines should do instead is straightforward: build or maintain a genuinely working OH&S management system on ISO 45001:2018 plus the 2024 climate amendment, quietly strengthen the areas the draft revision signals, and monitor the revision through official milestones rather than sales pitches. This page — maintained by Sterling’s consulting team, drawing on implementation work across 8,100+ clients worldwide — explains exactly what is verified, what is merely expected, and what to do now. Sterling is a consultancy: we build and prepare your system, and certification itself is always issued by an independent, accredited certification body, never by us.

What is actually changing in ISO 45001 — verified against ISO sources

Revision seasons attract noise, so let’s separate the record into three layers: what is published fact, what is formally in progress, and what is expectation. Everything in this section is checked against iso.org and official certification-body communications as of September 2026 — the same discipline we apply on our ISO revision and transition consulting hub.

Layer 1 — published fact: ISO 45001:2018 is current, with a live climate amendment

ISO 45001 was first published in March 2018, replacing OHSAS 18001. On iso.org, the 2018 edition is listed as reviewed and confirmed in 2024 and explicitly described as current. Its lifecycle status is “90.92 — to be revised,” which is ISO’s formal way of saying: this edition stands, and a successor is being drafted. A “to be revised” status does not invalidate anything. Organizations are being certified and recertified to ISO 45001:2018 today, and those certificates will remain valid through whatever transition window is eventually announced.

The one change that is already binding is Amendment 1:2024, “Climate action changes.” Published in 2024 across ISO’s management system standards, it adds two requirements to the context clauses: your organization must determine whether climate change is a relevant issue for its OH&S management system (Clause 4.1), and it must recognize that interested parties can have climate-related requirements (Clause 4.2). For Philippine operations this is not an abstraction. Heat stress on outdoor construction crews during heat-index advisories, typhoon and flood response for plant and site workers, and supply or utility disruption after severe weather are all climate-linked OH&S issues that auditors can reasonably expect you to have considered. If your context analysis has not been updated since 2023, that gap exists now — not in 2027.

Layer 2 — formally in progress: the revision is at DIS stage

The revision project is listed on iso.org as ISO/DIS 45001 — Occupational health and safety management systems — Requirements with guidance for use, under development by ISO/TC 283, and marked as the future replacement for ISO 45001:2018. Its lifecycle stage moved to 40.00 — Draft International Standard registered — on 17 April 2026. This matters for two reasons. First, DIS is further along than committee drafting: national standards bodies worldwide are now voting and commenting on a near-complete text, and the enquiry ballot closed on 9 September 2026 (stage 40.60, close of voting, on iso.org). The ballot result and any final draft (FDIS) stage are the next milestones. Second, DIS is still a draft. Texts change between DIS, any final draft stage, and publication. Nobody — not ISO, not any certification body, and certainly not any consultant — can tell you today exactly what the final requirements will say.

Layer 3 — reported direction of the draft: treat as signals, not requirements

Certification bodies reviewing the draft have consistently reported the same themes, and they are worth knowing as long as you hold them lightly:

• Psychological health and psychosocial risk — a stronger, more explicit expectation that mental health and workplace culture sit inside the OH&S system, not beside it.
• Worker wellbeing and workforce diversity — reported attention to how hazards affect different groups of workers differently, including gender-specific considerations.
• Changed ways of working — remote, hybrid, and digitally mediated work arrangements entering the risk picture.
• Outsourcing and contractor oversight — tightened expectations around externally provided processes and multi-employer worksites.
• Leadership accountability and worker participation — continued pressure on top management ownership and genuine consultation rather than paper committees.
• Alignment with the updated harmonized structure — keeping ISO 45001 consistent with the revision wave that has already produced ISO 14001:2026 and ISO 9001:2026, which simplifies integrated management systems.

We deliberately do not publish a clause-by-clause “what’s new in ISO 45001:2027” breakdown, because no final text exists to break down. Any page that gives you renumbered clauses and confident new requirements for an unpublished standard is reverse-engineering a draft that is still subject to ballot comments — and that tells you something about the publisher’s honesty. When the final standard is published, we will replace this analysis with a verified gap report as soon as we have read the official text, exactly as we are doing for the ISO 9001 revision.

Who must act, and by when — with honest dates

Here is the entire deadline picture for ISO 45001 as of September 2026. Note how short the “confirmed” column is:

Milestone	Status	Date
ISO 45001:2018 published	Confirmed	March 2018
Amendment 1:2024 (climate action) in force	Confirmed — applies now	2024
ISO 45001:2018 reviewed and confirmed as current	Confirmed	2024
ISO/DIS 45001 registered (stage 40.00)	Confirmed on iso.org	April 2026
DIS enquiry ballot closed (stage 40.60, close of voting)	Confirmed on iso.org	9 September 2026
Publication of the revised edition	Expected — ISO project page target, not yet a committed date	First half of 2027
Transition window for certified organizations	Not announced	Set only after publication; recent revisions have used roughly three years

So who actually needs to act right now?

Organizations already certified to ISO 45001:2018. Your certificate is valid and stays valid. Your only genuinely dated obligation is the climate amendment: surveillance audits since 2024 can examine whether Clause 4.1 and 4.2 analyses considered climate change. Beyond that, your job is to keep the system real — current hazard identification, live incident data, functioning worker consultation — so that whenever the transition window opens, you are upgrading a working system rather than resuscitating a dormant one.

Contractors and manufacturers certifying for the first time. Certify to ISO 45001:2018 now, without hesitation. Waiting for the revised edition means walking away from tender eligibility, client prequalification, and injury-rate improvements for a year or more, in exchange for nothing: every certificate issued against 2018 will carry over through the announced transition window, and organizations with mature 2018 systems historically make the easiest transitions. If ISO 45001 is on your bid checklist for DPWH-registered construction work, PEZA-locator supply chains, or multinational vendor accreditation, the standard that gets you qualified this year is the 2018 edition — full stop. Our ISO 45001 certification consulting page for the Philippines covers that path end to end.

Philippine employers generally. Remember that your hard legal deadlines come from Philippine OSH law, not from ISO. Republic Act 11058 and DOLE Department Order 198-18 already require hazard controls, safety officers, OSH committees, and reporting — with penalties — regardless of certification status. Employers also carry workplace mental-health policy obligations under the Mental Health Act and its DOLE implementing guidelines, which is precisely the terrain the ISO 45001 draft is reported to strengthen. A properly built ISO 45001:2018 system operationalizes these legal duties instead of duplicating them.

Nobody — and this deserves its own line — has a deadline to “move to the new ISO 45001.” Anyone who tells you otherwise before publication is inventing a date. We publish and maintain this page for the same reason we maintain the rest of our revision coverage: so Philippine companies can check claims against the record before signing anything.

The readiness path: what to do now, in order

“Monitor and wait” is honest but incomplete. There is real, no-regrets work that makes sense today because it improves your system under the 2018 edition and positions you for the revision. This is the sequence we run with clients:

1. Get certified — or stay solidly certified — to ISO 45001:2018 plus Amendment 1

Everything starts from a current, working system. If you are not yet certified, a structured implementation — hazard identification and risk assessment across your actual sites, legal compliance mapping to RA 11058 and D.O. 198-18, operational controls, emergency preparedness, worker consultation, internal audit, management review — followed by a certification audit from an accredited certification body is the whole path. If you are certified, treat the next surveillance audit as a health check, not a formality.

2. Close the climate-amendment gap this quarter

Update your Clause 4.1 context analysis to explicitly consider climate-related OH&S issues: heat stress and DOLE heat-index advisories for outdoor and non-air-conditioned work, typhoon and flooding response and business-hours decisions, post-disaster structural safety checks, and climate-driven expectations from principals and buyers (Clause 4.2). Document the determination even where the conclusion is “limited relevance” for a given site. This is the one revision-adjacent requirement that is already auditable.

3. Strengthen the signaled areas — because they are good 2018 practice anyway

Every reported theme in the draft is already implementable under the 2018 edition, and none of it is wasted if the final text shifts:

• Psychosocial risk: bring mental health into hazard identification — workload, shift patterns, harassment, isolation on remote sites — and connect it to the mental-health policy Philippine law already expects you to have.
• Contractor and multi-employer control: tighten prequalification, permit-to-work, and coordination for subcontracted trades. On Philippine construction sites where layered subcontracting is the norm, this is where fatalities cluster and where the draft points.
• Leadership and participation: make OSH committee consultation demonstrably real — decisions changed by worker input, not minutes filed. Auditors can tell the difference; so can your incident rate.
• Changed work arrangements: if you have hybrid office staff, field teams managed by app, or work-from-home roles, put those arrangements into the risk assessment now.

4. Put revision monitoring on one named desk

Assign one owner — usually the management representative or QHSE manager — to track exactly three sources: the iso.org project page for ISO/DIS 45001, your certification body’s transition bulletins, and one credible consulting digest. Everything else is noise. The milestones that matter are: DIS ballot result, any final draft stage, publication, and the official transition-window announcement. Each one should trigger a short management-review agenda item, nothing more.

5. Baseline yourself with a gap analysis — against the real standard

Run a structured gap analysis against ISO 45001:2018 + Amendment 1 as it stands. That gives you a defensible baseline: when the final revision publishes, your transition gap is measured from a known position instead of guesswork. You can start with our free online ISO gap analysis tool and graduate to a consultant-led assessment when you want site-level depth.

6. If you also run ISO 9001 or ISO 14001, plan one integrated wave

The same revision cycle is moving through the whole harmonized family: ISO 14001:2026 was published in April 2026 with its own transition window now running, ISO 9001:2026 was published on 16 September 2026, ISO 27701 was already revised in 2025, and ISO 45001 is expected to follow. Companies running integrated management systems should sequence one coherent update program — shared context analysis, one document-control update, coordinated audits — rather than three panicked mini-projects. The climate amendment logic, for instance, is common across standards and should be written once. If your integrated system extends into privacy, the same discipline applies to ISO 27701 PIMS consulting, where a real transition deadline does exist.

How Sterling delivers revision readiness: Revise™ inside Sterling OS™

Standing readiness for a moving standard is exactly what our Revise™ service line exists for. Revise™ is the transition and revision arm of Sterling OS™, our delivery operating system, and for ISO 45001 in its current pre-publication phase it works in two modes.

Now — the watch phase. We keep clients on the verified record: what iso.org says, what the technical committee has actually done, what certification bodies have scheduled. When a milestone lands, clients get a plain-language briefing that separates confirmed requirements from draft speculation. In parallel, we run the no-regrets program above: 2018-edition implementation or maintenance, climate-amendment updates, psychosocial and contractor-control strengthening, and a baseline gap analysis. Nothing in this phase asks you to buy a transition, because none exists to buy.

Later — the transition phase. As soon as the final text publishes, Revise™ converts to transition mode: a verified clause-by-clause comparison against the published standard, a gap assessment of your live system against the real changes, a prioritized update plan, documentation and training updates, an internal audit cycle against the new edition, and coordination with your certification body’s transition audit scheduling — early in the window, when auditor calendars are open, rather than in the end-of-window rush every revision produces.

Around Revise™, the rest of Sterling OS™ carries the implementation load in whichever mode fits your team: Design™ where we guide and your people implement, Drive™ where our consultants do the heavy lifting on documentation and rollout, Sustain™ where we keep the system audit-ready between certifications, and Automate™ where software carries document control, action tracking, and audit trails so the transition, when it comes, is a configuration update rather than a paper hunt.

One boundary is permanent and worth restating: Sterling never issues certificates. We are consultants. Your ISO 45001 certificate — today’s 2018 edition and the eventual revised edition — is always issued by an independent certification body accredited by a recognized accreditation body, after their own auditors examine your system. Any provider that offers to both “prepare and certify” you is describing a conflict of interest that accredited certification explicitly prohibits.

Mistakes companies make when a revision is announced

Buying an upgrade to a standard that doesn’t exist. The moment a revision hits the news, certificate mills start selling “new version” packages. There is nothing to upgrade to. Worse, some issue certificates naming unpublished editions — a document that fails the first prequalification check a competent procurement officer runs.

Freezing certification plans to wait for the new edition. This is the mirror-image error, and it costs more. A company that delays certification for a year forfeits tender eligibility and the injury-reduction benefits of a managed system, and then faces the revision from a standing start. Certificates issued to the 2018 edition carry through the transition window; there is no scenario where waiting wins.

Rewriting documentation against the DIS. Draft texts change through ballot and final drafting. Rebuilding your manual against a draft means paying twice — once now, once when the real text lands. Read drafts for direction; implement only published requirements.

Ignoring the amendment that is already in force. While attention drifts to 2027, the climate amendment sits quietly auditable in 2026. It is a small gap to close and an unnecessary nonconformity to receive.

Treating the revision as a documentation exercise. The signaled direction — psychological health, culture, participation, contractor reality on multi-employer sites — is precisely the material that cannot be templated. A binder update will not survive an audit interview with your scaffolders, machine operators, or night-shift supervisors. Systems that only exist on paper are exposed a little more by every revision cycle, which is rather the point of revising.

Leaving monitoring to nobody. Companies without a named owner for standards-watching either miss the transition window’s opening — losing the calm early slots — or overreact to every vendor email. One desk, three sources, four milestones.

Letting the system drift because “a new version is coming anyway.” Surveillance findings left open and risk assessments left stale don’t get amnesty at transition time. They compound: the eventual upgrade becomes a rescue project. The cheapest transition is the one done from a healthy system.

Why Philippine contractors and manufacturers work with Sterling

Sterling has delivered management-system consulting to 8,100+ clients worldwide, including Philippine construction firms, manufacturers, logistics operators, and service companies, with ISO 45001 work running from single-site fabrication shops to multi-site contractors juggling layered subcontracting. That practitioner base changes how we handle a revision cycle: we have taken clients through transitions before — OHSAS 18001 to ISO 45001 among them — and we know the difference between what a draft says and what an auditor eventually checks.

Our approach is deliberately anti-shortcut. We publish verified status instead of countdown theatrics; we hedge what is unconfirmed and say so in plain text; we tell first-time certifiers to proceed with the 2018 edition because that is what the record supports, not because urgency sells. We build systems around your actual operations — your DOLE obligations, your sites, your subcontractors, your incident history — because those are the systems that pass audits, cut injuries, and transition cheaply when new editions land. And we keep the consulting and certification roles separate, always: our work ends with your system audit-ready, and an accredited certification body’s auditors make the certification decision independently.

If you want a straight answer on where your OH&S system stands — against the 2018 edition today, and against the revision when it becomes real — talk to our consultants and we will lay out the honest picture, including anything that says “you don’t need us yet.”

Integrated QHSE teams: while the ISO 45001 revision is still in progress, ISO 9001:2026 (published 16 September 2026) and ISO 14001:2026 are already in transition. The ISO 9001:2026 training courses include integrated internal auditor and lead auditor courses across the three standards, and ISO 9001:2026 for DPWH contractors covers integrated QHSE evidence on site.

Frequently asked questions about the ISO 45001 revision

Is ISO 45001:2018 still valid in 2026?

Yes. ISO 45001:2018 is the current, published edition of the standard. ISO’s official listing shows it was reviewed and confirmed in 2024 and remains current, with lifecycle status “to be revised” — meaning a successor is being drafted, not that the 2018 edition is withdrawn. Certificates to ISO 45001:2018 are valid and continue to be issued and renewed today.

Has ISO 45001:2027 been published?

No. No revised edition of ISO 45001 has been published as of September 2026, and “ISO 45001:2027” is a market nickname, not an official designation. The revision exists only as ISO/DIS 45001, a Draft International Standard registered in April 2026. ISO’s project page indicates publication in the first half of 2027, but that is a target rather than a committed date. Treat any certificate or service naming a post-2018 edition as a red flag.

What stage is the ISO 45001 revision at right now?

As of September 2026, the project sits at DIS (Draft International Standard) stage — DIS registered on 17 April 2026 and the ballot closed on 9 September 2026 (stage 40.60, close of voting, on iso.org) — under ISO/TC 283. National standards bodies have voted and commented; the ballot result, any final draft (FDIS) stage and publication are the next milestones. ISO’s project page indicates publication in the first half of 2027.

What is Amendment 1:2024, and does it affect us now?

Amendment 1:2024, “Climate action changes,” was added to ISO 45001:2018 in 2024 as part of a coordinated update across ISO management system standards. It requires you to determine whether climate change is relevant to your OH&S management system and to recognize climate-related requirements of interested parties. It applies now, and auditors can check it at surveillance and certification audits. For Philippine sites, heat stress, typhoon response, and flood-related risks are the obvious entry points.

Will our ISO 45001:2018 certificate become invalid when the new edition publishes?

No. When a revised edition publishes, a transition window is announced — for recent management-system revisions this has been roughly three years — during which 2018-edition certificates remain valid while organizations upgrade and complete a transition audit with their certification body. Certificates do not lapse on publication day. The exact window for ISO 45001 will be announced only after publication; any specific end-date quoted today is invented.

What will change in the revised ISO 45001?

Nothing is final until publication. Themes consistently reported from the draft by certification bodies include stronger treatment of psychological health and psychosocial risk, worker wellbeing and workforce diversity, remote and hybrid work arrangements, contractor and outsourcing oversight, leadership accountability and worker participation, and alignment with the updated harmonized structure shared with ISO 9001 and ISO 14001. Treat these as direction for strengthening your current system, not as requirements you can implement from a draft.

Should we wait for the new version before getting certified?

No. Certify to ISO 45001:2018 plus Amendment 1 now. Your certificate carries through the eventual transition window, mature systems transition most easily, and waiting costs you tender eligibility and the operational benefits of a working OH&S system in the meantime. There is no advantage to waiting for a publication that is still months away.

How long will the transition period be?

It has not been announced, because the standard is not published. Recent ISO management-system revisions have used transition windows of roughly three years from publication, set through the accreditation community, and certification bodies expect a similar pattern here — but that is expectation, not commitment. We will update this page with the official window when it exists.

Does Philippine law require ISO 45001 certification?

No law makes ISO 45001 certification mandatory in general. However, Republic Act 11058 and DOLE Department Order 198-18 impose enforceable OSH duties on employers — safety officers, OSH committees, hazard controls, reporting — and many government and private tenders, developer prequalifications, and multinational supply chains ask for ISO 45001 as evidence of a managed system. A well-built ISO 45001 system is the cleanest way to run your legal compliance and your commercial qualification through one framework.

Can Sterling issue our ISO 45001 certificate?

No — and be wary of anyone who says yes to that question about themselves. Sterling is a consultancy: we implement, document, train, audit internally, and prepare you. The certificate is issued by an independent certification body accredited by a recognized accreditation body, after its own audit. Keeping those roles separate is a requirement of credible certification, and it is why certificates from consultant-cum-certifier outfits fail due diligence.

How should we monitor the revision without chasing rumors?

Track three sources: the iso.org project page for ISO/DIS 45001 (the authoritative stage record), your certification body’s transition bulletins, and one consulting digest you trust. Ignore countdowns and unofficial clause leaks. The only milestones that require action are the ballot outcome, publication, and the official transition-window announcement — and we flag each of them through our transition consulting hub as they occur.

We run ISO 9001, ISO 14001 and ISO 45001 together — how do we handle all the revisions?

As one program, not three. The revisions share the updated harmonized structure and common threads such as climate considerations, so an integrated system should sequence a single update wave: one context refresh, one document-control update, coordinated internal audits, and aligned transition audits with your certification body. Start from what is already published — ISO 14001:2026 and ISO 9001:2026 are both published (see our ISO 9001 transition coverage) — and fold the ISO 45001 changes into the same machinery when its text and window become official.
