| Target Audience | WHS managers, quality managers, EHS directors, ISO certification project leads |
| Key Entities | ISO 45001:2018, Safe Work Australia, certification bodies (SAI Global, Bureau Veritas, SGS, etc.) |
| Regulations & Standards | ISO 45001:2018 Occupational health and safety management systems — Requirements with guidance for use; PDCA (Plan-Do-Check-Act) management system framework |
| Key Fact 1 | ISO 45001 replaced OHSAS 18001 in 2018 and is now the international standard for OHS management systems — organisations certified to OHSAS 18001 had until 2021 to transition. |
| Key Fact 2 | ISO 45001 is a management system standard, not a technical standard — it does not specify WES values or monitoring methods. It provides the framework; occupational hygiene practice fills the technical content. |
| Key Fact 3 | ISO 45001 Clause 8.1.2 requires that processes for managing hazardous processes and products are in place — a direct hook for formalising occupational hygiene programme elements within the OHS management system. |
| What This Covers | ISO 45001 structure overview, mapping of hygiene programme elements to specific clauses, documented information requirements for hygiene activities, management review obligations |

ISO 45001 and Occupational Hygiene: Integrating Chemical and Dust Risk into Your OHS Management System
ISO 45001:2018 is the international standard for occupational health and safety (OHS) management systems. Like all ISO management system standards, it is built on the Plan-Do-Check-Act (PDCA) cycle and the high-level structure (Annex SL) that allows integration with ISO 9001 (quality) and ISO 14001 (environment). ISO 45001 does not specify technical OHS requirements — it does not tell you what the WES for silica is or how to measure noise. What it does is provide a systematic management framework for identifying hazards, assessing risks, implementing controls, monitoring performance, and continuously improving. Occupational hygiene programmes are the technical content that fills this framework for chemical, dust and physical hazard management.
Key ISO 45001 Clauses Relevant to Occupational Hygiene
Clause 4.1 — Understanding the Organisation and Its Context
The organisation must determine external and internal issues relevant to its OHS management system. For occupational hygiene, this means: understanding the regulatory framework (WES values, health monitoring obligations, codes of practice applicable to the industry sector); understanding the internal processes and materials that create exposure potential; and identifying relevant stakeholders (workers, regulators, occupational health providers).
Clause 6.1 — Actions to Address Risks and Opportunities
The core of the ISO 45001 risk management requirement. The organisation must establish and maintain processes to identify hazards (including chemical and dust hazards), assess the associated OHS risks, and determine controls consistent with the hierarchy. For occupational hygiene, this clause requires: a documented hazard identification process that captures airborne contaminant hazards; a documented risk assessment methodology (qualitative or quantitative) for each significant hazard; and a documented control selection process applying the hierarchy of controls.
Clause 8.1.2 — Eliminating Hazards and Reducing OHS Risks
Specifically requires organisations to establish, implement and maintain processes for the elimination of hazards and reduction of OHS risks. For chemical hazards, this maps directly to the hierarchy of controls — processes for substitution review, engineering control specification and maintenance, administrative control implementation, and RPE selection and programme management.
Clause 9.1 — Monitoring, Measurement, Analysis and Evaluation
Organisations must determine what needs to be monitored (including OHS performance, extent to which legal requirements are met, and effectiveness of controls). For occupational hygiene, this clause requires: a defined monitoring programme identifying which hazards require air monitoring, at what frequency, and against what standard; processes for comparing results to WES and evaluating compliance; and documented procedures for responding to exceedances.
Clause 9.3 — Management Review
Top management must review the OHS management system at planned intervals. Inputs must include OHS performance data and evidence of conformity with legal requirements. This is the clause that drives occupational hygiene summary reporting to executive or board level — annual monitoring results, health surveillance outcomes, WES exceedances and corrective actions should be presented as standard management review inputs.
Documented Information Requirements for Hygiene Activities
ISO 45001 distinguishes between “documented information” that must be maintained (documents — controlled procedures, policies) and documented information that must be retained (records — evidence of activities performed). For occupational hygiene:
Documents to Maintain
- Chemical hazard identification and risk assessment procedure
- Occupational hygiene monitoring programme specification (who monitors what, when, and how)
- Health monitoring procedure (when triggered, what it includes, who administers it)
- Control hierarchy decision procedure (how substitution is evaluated, how LEV is specified)
- RPE selection and management procedure
Records to Retain
- Completed risk assessments for each chemical and dust hazard
- Air monitoring reports, laboratory certificates, and WES comparison analyses
- Health monitoring enrolment register and individual results (privacy-protected)
- LEV commissioning and inspection records
- RPE fit test records
- Training records for hazardous substance procedures
Using ISO 45001 Certification to Demonstrate Hygiene Programme Credibility
Third-party certification to ISO 45001 by an accredited certification body (SAI Global, Bureau Veritas, SGS, DNV, etc.) provides external validation that the organisation’s OHS management system, including its occupational hygiene programme, meets the international standard. Certification auditors will specifically review evidence of hazard identification, risk assessment, monitoring programme implementation and management review for chemical and dust hazards. A strong occupational hygiene programme — with current monitoring records, active health surveillance, and documented control verification — significantly smooths the certification audit process.
