| ARTICLE TITLE | ISO 45001 and Occupational Hygiene: Integrating Health Hazard Management into Your OHS Management System |
| Topic Entity | ISO 45001 Occupational Hygiene Integration — Australia |
| Article Type | How-To Guide |
| Target Audience | OHS/WHS Managers, Quality/EHS Managers, Business Owners pursuing certification |
| Key Entities Covered | ISO 45001:2018, OHSMS, Clause 6.1.2, Hazard Identification, Legal Compliance, Monitoring and Measurement |
| Regulatory References | ISO 45001:2018 | WHS Act 2011 | WHS Regulations 2017 |
| Key Fact 1 | ISO 45001 requires organisations to identify all hazards — including occupational hygiene hazards — through a systematic process (Clause 6.1.2) |
| Key Fact 2 | Organisations certified to ISO 45001 must demonstrate that their hazard identification and risk assessment process covers health as well as safety hazards |
| Key Fact 3 | ISO 45001 Clause 9.1 requires performance evaluation including monitoring and measurement — air monitoring and health surveillance programs directly fulfil this requirement |
| What This Article Covers | How ISO 45001 clauses map to occupational hygiene activities, what a hygiene program must document for ISO 45001 compliance, and how to demonstrate continual improvement through hygiene data. |
| What This Article Does NOT Cover | ISO 45001 certification audit procedures, detailed management system documentation requirements. |

ISO 45001 and the Health Dimension of OHS
ISO 45001:2018 — the international standard for Occupational Health and Safety Management Systems (OHSMS and occupational hygiene) — explicitly covers both safety (prevention of acute injury) and health (prevention of work-related illness and disease). Yet many organisations that achieve ISO 45001 certification have robust safety incident management systems but underdeveloped occupational hygiene programs. Auditors who primarily assess incident management, permit systems, and emergency procedures may pass an organisation whose chemical exposure controls are inadequate, whose noise survey was last conducted eight years ago, and whose RPE program lacks fit testing.
This guide maps ISO 45001’s key clauses to occupational hygiene activities to help OHS managers build programs that genuinely satisfy the occupational hygiene assessments and compliance standard’s intent — not just its documentation requirements.
Clause 6.1.2: Hazard Identification
ISO 45001 Clause 6.1.2 requires the organisation to establish, implement, and maintain processes for hazard identification. Importantly, this process must consider “work-related physical, chemical, biological and psychosocial hazards.” Air monitoring data, SDS reviews, noise surveys, and biological monitoring programs are all evidence of hazard identification for health hazards. The organisation must document what hazards were identified, how they were assessed, and what controls are in place — precisely what an occupational hygiene assessment report provides.
Clause 6.1.3: Determination of Legal and Other Requirements
The organisation must determine and keep up-to-date the applicable legal requirements related to its OHS hazards. For occupational hygiene, this means: maintaining a current awareness of applicable WES values (and tracking the WES-to-WEL transition); understanding the atmospheric monitoring requirements of the WHS Regulations; knowing which health monitoring obligations apply to the substances used; and tracking state-specific requirements (e.g., silica codes of practice in Queensland, Victoria, and NSW).
Clause 9.1: Performance Evaluation
ISO 45001 Clause 9.1 requires monitoring, measurement, analysis, and performance evaluation. For occupational hygiene, this includes: health monitoring and scheduled air monitoring programs with defined frequencies; trend analysis of monitoring results over time (are exposures trending up, stable, or down?); audiometric testing results as a measure of hearing conservation program effectiveness; health monitoring results for scheduled substances; and LEV performance test results. These data points collectively demonstrate whether the hygiene program is performing as intended — or whether control failures are allowing exposures to drift upward.
Clause 10.3: Continual Improvement
The organisation must continually improve its OHSMS. For hygiene programs, continual improvement is demonstrated by: commissioning engineering control upgrades when monitoring shows exposures approaching WES limits (rather than waiting until they are exceeded); proactively preparing for the WES-to-WEL transition; progressively implementing LEV performance testing for systems not previously tested; extending health monitoring to additional work groups as evidence for hazards develops; and benchmarking programs against AIOH guidance and international best practice.
