What is the ISO 45001:2018 Occupational Health and Safety Management System Standard?
The ISO 45001:2018 Occupational Health and Safety (OHS) Management System Standard provides a framework for managing and preventing work-related injury and illness by identifying risks and opportunities to eliminate hazards and minimise risks, including system deficiencies. Also commonly known as Works Health and Safety (WHS), this international workplace safety standard assists organisations of any size, type, or industry in taking effective preventative actions to promote a safe and healthy workplace, while also effectively helping businesses with addressing legal and ethical concerns.
Various factors can contribute to the hazards and risks associated with poor working conditions, such as: governance gaps, failure to comply with the law, insufficient resources, scarce knowledge, unsustainable business practices, and the lack of a culture of prevention, just to name a few. Effective implementation of the ISO 45001:2018 Standard should provide a systematic approach to enable organisations to address and manage these OHS risks, and improve their ethical and safety reputation among customers, employees, and other stakeholders.

ISO 45001 Standard Documents
The ISO 45001:2018 Standard is an actual document developed by the International Organisation for Standardisation (ISO) detailing the standard’s clauses and requirements. We recommend that your business purchases a copy of the ISO 45001:2018 Standard document, to fully understand the requirements for successful implementation. Visit Standards Australia to purchase a copy.
The Benefits of ISO 45001 Occupational Health and Safety Management Systems
Safer and Healthier Workplace
ISO 45001:2018 establishes a comprehensive framework for managing workplace health and safety. It empowers businesses to create a proactive culture focused on reducing risks and preventing accidents, ensuring the health and well-being of employees. This structured approach leads to fewer workplace injuries, safer working conditions, and a healthier workforce.
Hazard Identification and Control
The ISO 45001 emphasises identification, evaluation, and control of potential hazards. With a systematic risk assessment process, businesses can address unsafe conditions before they lead to incidents, ensuring that appropriate control measures are put in place, and supports a culture of safety in the organisation.
Employee Satisfaction and Safety
Implementing ISO 45001 fosters a safe and supportive work environment where employees feel valued and protected. By prioritising health and safety, businesses improve employee morale, reduce stress, and build trust. This leads to increased employee satisfaction, enhanced engagement, and a greater sense of security at work, which can contribute to higher retention and productivity.
Productivity with Fewer Incidents and Downtime
By reducing workplace accidents and health-related issues, ISO 45001:2018 Occupational Health and Safety contributes to less downtime and fewer disruptions. With fewer incidents, businesses experience less unplanned downtime, lower absenteeism, and minimal operational disruptions.
Greater Management of Health and Safety Risks
ISO 45001:2018 provides businesses with a structured approach to managing health and safety risks through comprehensive risk assessments, monitoring, and mitigation strategies. By integrating regular reviews and continuous improvement, companies can effectively manage and reduce safety risks, ensuring compliance with regulations and enhancing overall safety performance.
General Benefits of ISO Management System Standards
Qualify for Tenders, Contracts and International Trade
Certification to ISO 45001:2018 reflects your commitment to global best-practice health and safety management. It enhances your organisation’s reputation and trust with stakeholders. This can open doors to new markets and business growth, while also meeting tender requirements, including for large and international contracts.
Improve Brand Reputation and Stakeholder Confidence
Certification to ISO 45001 is a confirmation to the stakeholders that your organisation meets globally recognised work and safety standards, enhancing your brand credibility and professional image. This builds greater trust with clients, investors, partners, and regulators.
Improve Business Planning and Align With Strategy
Promoting a structured, process-based approach to safety management, which supports better strategic planning and decision-making. With clearly WHS defined objectives, performance metrics, and risk controls, businesses can align their operations with their long-term vision and drive consistent improvements across all departments.
Higher Profit & Reduced Costs via Improved Efficiencies
You’ll typically benefit from streamlined processes, reduced incidents, and fewer errors or disruptions. By identifying inefficiencies and addressing operational risks early, businesses can cut costs, reduce fines and injury claims, improve resource use, and boost productivity.
Improve Business Structure for Sustainable Growth
This leads to the standardisation of WHS procedures and documentation, which strengthens internal systems and promotes consistency across teams. This foundation supports scalable growth, enabling your business to expand confidently while maintaining safety and performance.

ISO 45001 Certification Process: Step-by-Step Guide
Achieving Certification to ISO 45001:2018 signifies that an organisation has successfully demonstrated its commitment to robust Occupational Health and Safety Management. The journey to achieve certification includes the following steps:
01
Planning
& Gap Analysis
Comprehending the standard ISO 45001requirements is vital. Planning may also entail conducting a Gap Analysis to grasp the current state of the organisation’s documentation against the ISO 45001 requirements, unless beginning fresh. Subsequently, a strategy is developed to address these gaps and create a structured path for the certification process.
02
Documentation & OHS Development
In this phase, documentation must be developed to form an Occupational Health & Safety Management System (OHSMS), including OHS policies, risk assessment procedures, work instructions, emergency plans and business planning documentation. This is the point where the knowledge in comprehending and implementing the Standard requirements comes into play, and expert consultants help you save money and time by strategically addressing these tasks.
03
Implementation, Training & Coaching
The implementation of the OHS (also known as WHS) Management System is extended throughout the entire organisation, and proper guidance for employees to understand the documentation and their respective duties is key at this stage. Implementation involves integrating the documented processes into everyday operations, regularly overseeing activities to ensure they are followed correctly, and collecting evidence and data to evaluate performance and effectiveness.
04
Management Review & Internal Audit
An internal audit, as required by ISO 45001:2018, evaluates how well your OHS Management System meets the standard’s requirements and identifies any gaps or areas for improvement. Management Reviews, also mandated by the standard, assess performance data and the overall effectiveness of the OHSMS to ensure it remains suitable, adequate, and aligned with the organisation’s health and safety objectives. This process supports informed decision-making, prioritises corrective actions, and promotes continual improvement in workplace safety.
05
External Audits & Certification
During this step, you need to engage a Certification Body (aka Conformity Assessment Bodies). These accredited organisations will conduct the Certification (External) Audits to evaluate your organisation’s OHSMS against the ISO 45001 requirements. Auditors will assess the management system’s effectiveness, its conformance with ISO 45001 standards, and its capacity to deliver reliable outcomes. Following a successful completion of the Certification Audit, your organisation will receive the ISO 45001 Certification. Find out how to select the right Certification Body for your business.
06
Continual Improvement
Once Certification to ISO 45001 is achieved, it’s valid for 3 years. Over this time, your Certification Body will return to conduct annual surveillance audits to verify your business ongoing commitment to its OHS management. Ongoing activities are required by your organisation to be regularly conducted, ensuring your OHSMS continues to meet the requirements of the ISO 45001 standard, and your Certification Body auditor will check evidence of this.

Discover the industries we’ve successfully supported with consulting services to ISO 45001 below.
ISO 45001 for Construction
The construction industry is one of the highest-risk sectors, with common hazards including falls from heights, heavy machinery accidents, and electrical risks. Implementing ISO 45001 ensures you implement controls such as strict risk assessments, site safety planning, and mandatory worker training. Organisations must also focus on contractor safety management and emergency preparedness to reduce workplace injuries and meet safety regulations.
ISO 45001 for Healthcare
In healthcare, workers face risks such as biological hazards, patient handling injuries, and exposure to hazardous substances. ISO 45001 strengthens workplace safety by implementing infection control measures, safe patient handling protocols, and mental health support programs. Hospitals and healthcare facilities must also ensure emergency response preparedness and compliance with healthcare-specific safety regulations.
ISO 45001 for Professional Services
Though lower-risk, office environments still face WHS issues, including work-related stress, ergonomic issues, and fire hazards. ISO 45001:2018 certification enhances safety by promoting ergonomic workstation setups, mental health awareness programs, and clear emergency and evacuation procedures.
ISO 45001 for Retail & Hospitality
Retail and hospitality workers can deal with customer interactions, slip and trip hazards, and workplace violence risks. ISO 45001helps businesses improve areas like store layout safety, establish injury reporting systems, and train employees on conflict resolution. Effective safety policies also ensure compliance with local occupational health regulations, reducing liability risks.
ISO 45001 for Manufacturing
Manufacturing workplaces can expose employees to hazardous machinery, repetitive strain injuries, and exposure to chemicals. ISO 45001:2018 helps mitigate these risks with controls such as enforcing proper machine guarding, personal protective equipment policies, and workplace ergonomics programs. Manufacturers must also prioritise regular equipment maintenance and hazard identification to prevent accidents and improve efficiency.
ISO 45001 for Transport & Logistics
Employees in transport and logistics face risks related to vehicular accidents, manual handling injuries, and exposure to hazardous cargo. Implementing ISO 45001 supports the introduction of safety measures like strict driver training, fatigue management programs, and compliance with road safety regulations. Businesses must also focus on ergonomic lifting techniques and warehouse hazard identification to prevent injuries.
ISO 45001 for Mining
Mining is one of the most hazardous industries, with risks such as explosions, cave-ins, and exposure to toxic gases. ISO 45001OHSMS enhances safety by requiring regular risk assessments, proper ventilation systems, and strict PPE requirements. Companies must also establish comprehensive emergency response plans and routine equipment safety checks to protect workers in high-risk environments.
ISO 45001 for Agriculture & Farming
Agricultural workers face equipment-related injuries, pesticide exposure, and extreme weather conditions. ISO 45001:2018 certification promotes safe equipment handling, chemical safety training, and heat stress prevention programs. Farms and agribusinesses must also prioritise vehicle safety and employee training on handling livestock-related hazards.
History of ISO 45001
ISO technical committees perform evaluations of all ISO Standards roughly every five years. If a standard is modified and improved due to such an evaluation, a new edition of the standard will be issued by ISO, with the new title indicating the year in which the revision occurred.
While the first and still current version of ISO 45001 was published in 2018. Until recently, and before ISO 45001 was published, there were other WHS standards previously available for businesses to get Certified to, which are all now superseded by ISO 45001:2018. Here is a brief history of the ISO 45001 Occupational Health and Safety Management System Standard:
OHSAS 18001:2007
Withdrawn
First published in 1999, OHSAS 18001 provided a framework for organisations to manage their OH&S risks and ensure compliance with relevant laws and regulations. While it wasn’t an official ISO Standard, OHSAS 18001 was superseded at the end of 2021 by ISO 45001:2018.
AS/NZS 4801:2001
Withdrawn
AS/NZS 4801 is an Australian and New Zealand standard for OH&S Management Systems. It provides a framework for organisations to manage their occupational health and safety risks, and improve the safety and well-being of employees. AS/NZS 4801:2001 was superseded by ISO 45001:2018 in July 2023.
ISO 45001:2018
Current Version
Published for the first time in 2018, ISO 45001 was created to provide a more comprehensive and globally recognised standard for occupational health and safety management. Prior to its creation, different countries had their own standards and regulations for OH&S management, which made it difficult for organisations operating across borders to ensure compliance with all the relevant requirements.
ISO 45001:2027
Draft
This is the next version which is due for publication during 2027. Find out more about the upcoming new version of the ISO 45001 standard here.
