The core principle being tested here is the systematic nature of hazard identification and risk assessment (HIRA) as mandated by ISO 45001:2018, specifically Clause 6.1.2. This clause requires organizations to establish, implement, and maintain a process for hazard identification, risk assessment, and control of risks. The process must consider a wide range of factors, including those arising from normal operations, abnormal operations, and emergency situations. It also emphasizes the need to consider existing controls and their effectiveness. The question probes the understanding of how to proactively identify potential hazards that might not be immediately obvious or directly linked to current activities but could arise from future changes or external factors. The correct approach involves a forward-looking perspective that anticipates potential issues before they manifest. This includes considering changes in work processes, equipment, materials, and even organizational structure. The inclusion of “potential for new hazards arising from changes” directly aligns with the proactive and preventive nature of ISO 45001. The other options, while related to safety, do not encompass the full scope of proactive hazard identification required by the standard. Focusing solely on immediate operational risks, documented incidents, or regulatory compliance without a forward-looking element would be insufficient. The standard requires a comprehensive approach that anticipates future states and potential disruptions.

The core principle being tested here is the systematic approach to hazard identification and risk assessment as mandated by ISO 45001:2018, specifically Clause 6.1.2. This clause requires organizations to establish, implement, and maintain a process for hazard identification and risk assessment. The process must consider normal operating conditions, foreseeable abnormal situations, and emergency situations. It also mandates the consideration of hazards arising from the work environment, existing controls, and the potential for worker participation. The question probes the understanding of how to effectively integrate these elements into a robust HIRA process, particularly when dealing with a novel or evolving operational context. The correct approach involves a comprehensive review that encompasses not only immediate physical hazards but also systemic factors, worker input, and the lifecycle of operations, ensuring that the assessment is proactive and thorough. This aligns with the standard’s emphasis on preventing work-related injury and ill health. The other options represent incomplete or less effective strategies. Focusing solely on immediate physical risks overlooks potential psychosocial hazards or those arising from changes in work design. Relying only on historical data might miss emerging risks. Limiting the scope to documented procedures fails to capture the dynamic nature of work and the insights of those performing it. Therefore, a holistic and forward-looking methodology, incorporating worker consultation and considering all operational phases, is paramount for effective HIRA under ISO 45001.

The core principle being tested here is the systematic approach to hazard identification and risk assessment as mandated by ISO 45001:2018, specifically Clause 6.1.2. This clause requires organizations to establish, implement, and maintain a process for hazard identification, risk assessment, and control of risks. The process must consider normal operating conditions, foreseeable abnormal conditions, and situations arising from reasonably foreseeable emergencies. It also emphasizes the need to identify hazards arising from the organization’s activities, products, and services, and to consider those under its control but located at its workplace, and those under its influence but occurring at its workplace. Furthermore, the standard requires consideration of hazards arising from the design of workplaces, work systems, work processes, and work organization, as well as the introduction of new or changed activities, products, and services. The inclusion of legal and other requirements is also a critical component. Therefore, a comprehensive HIRA process must encompass not only immediate operational hazards but also systemic factors, lifecycle considerations, and external influences. The correct approach involves a multi-faceted investigation that goes beyond simply observing current tasks. It requires proactive engagement with all relevant stakeholders, thorough documentation, and a continuous improvement loop. The process should be dynamic, adapting to changes in the organization and its operating environment. The emphasis on considering “reasonably foreseeable emergencies” and “situations arising from the design of workplaces, work systems, work processes and work organization” points towards a holistic and preventative strategy, rather than a reactive one. This aligns with the overall intent of ISO 45001 to prevent work-related injury and ill health.

The core principle being tested here is the systematic approach to hazard identification and risk assessment as mandated by ISO 45001:2018, specifically Clause 6.1.2. This clause requires organizations to establish, implement, and maintain a process for hazard identification and assessment of risks and opportunities. The process must consider a wide range of factors, including those arising from normal operating conditions, abnormal conditions, and emergency situations. It also emphasizes the need to consider the life cycle of products and services, including design, development, production, delivery, use, and disposal. Furthermore, the standard requires consideration of changes or proposed changes in the organization, its activities, products, or services, and the introduction of new products, services, and processes. The inclusion of worker participation and consultation is also a critical element.

The scenario describes a manufacturing facility introducing a new automated welding process. The question probes the most comprehensive and compliant approach to identifying potential hazards and assessing risks associated with this change. The correct approach must encompass not only the immediate operational aspects of the new machinery but also the broader implications across the entire lifecycle and organizational context. This includes considering the design phase of the new process, the training of personnel, the potential for ergonomic issues with the new interface, the maintenance requirements, and the disposal of any associated waste or old equipment. It also necessitates the involvement of workers who will be directly affected by the change, as per ISO 45001’s emphasis on worker participation.

The incorrect options represent approaches that are either too narrow in scope, focusing only on immediate operational risks, or rely on less systematic methods. For instance, an option that solely focuses on the operational phase of the new machinery overlooks hazards during installation, decommissioning, or maintenance. Another might emphasize external regulatory compliance without fully integrating the organization’s internal risk assessment processes. A third might focus on a single aspect like worker training without a holistic view of all potential hazards and risks. The correct option, therefore, is the one that reflects a thorough, lifecycle-oriented, and participative hazard identification and risk assessment process, aligning with the intent and requirements of ISO 45001:2018 Clause 6.1.2.

The core principle being tested here is the systematic approach to hazard identification and risk assessment as mandated by ISO 45001:2018, specifically Clause 6.1.2. This clause requires organizations to establish, implement, and maintain a process for hazard identification, risk assessment, and control of risks. The scenario describes a situation where a new chemical is introduced, necessitating a proactive HIRA process. The correct approach involves a comprehensive review of the chemical’s properties, potential exposure routes, existing controls, and regulatory requirements before its use. This aligns with the standard’s emphasis on considering the life cycle of products and services, including their design, development, delivery, and disposal. Specifically, understanding the Safety Data Sheet (SDS) is paramount for identifying inherent hazards. Evaluating potential exposure scenarios for workers, considering the quantities used, frequency of handling, and the effectiveness of current or planned engineering and administrative controls, is crucial. Furthermore, compliance with relevant national legislation, such as occupational health and safety regulations governing chemical handling and exposure limits, must be integrated. The process should also anticipate potential deviations from normal operating conditions and emergency situations. Therefore, a structured approach that integrates these elements—from understanding the substance’s intrinsic properties to evaluating workplace-specific exposure and regulatory compliance—forms the foundation of an effective HIRA for new materials.

The core principle being tested here is the systematic approach to hazard identification and risk assessment as mandated by ISO 45001:2018, specifically Clause 6.1.2. This clause requires organizations to establish, implement, and maintain a process for hazard identification, risk assessment, and control of risks. The process must consider routine and non-routine activities, all persons under the organization’s control, changes or anticipated changes, and conditions arising from emergencies. It also emphasizes the need to identify hazards and assess risks associated with them, taking into account existing controls. The question probes the understanding of how to integrate external information and internal data to create a comprehensive hazard register. The correct approach involves a structured review of all relevant sources, ensuring that the identified hazards are specific, actionable, and linked to potential risks. This systematic compilation forms the foundation for subsequent risk evaluation and the development of appropriate control measures. The process should not be ad-hoc but rather a continuous cycle of identification, assessment, and review. The emphasis on “all persons under the organization’s control” and “changes or anticipated changes” highlights the dynamic nature of hazard management. The correct option reflects a thorough, documented, and integrated process that considers the full scope of the organization’s operations and potential influences.

The core principle being tested here is the systematic approach to hazard identification and risk assessment as mandated by ISO 45001:2018, specifically Clause 6.1.2. This clause requires organizations to establish, implement, and maintain a process for hazard identification, risk assessment, and control of risks. The process must consider routine and non-routine activities, conditions arising in the vicinity of the workplace, situations outside the workplace that are under the organization’s control, and the behavior, actions, and omissions of workers and others at the workplace. It also emphasizes considering existing controls and the potential for new hazards arising from changes.

The scenario describes a manufacturing facility implementing a new automated welding process. The question probes the most comprehensive and compliant method for identifying potential hazards associated with this change. Option (a) correctly reflects the ISO 45001 requirement to consider the entire lifecycle and context of the change, including potential interactions with existing systems, human factors, and the broader operational environment. This aligns with the proactive nature of the standard, which aims to prevent incidents before they occur.

Option (b) is too narrow, focusing only on the immediate operational aspects of the new equipment and neglecting the broader system interactions and human factors. Option (c) is also insufficient as it prioritizes external regulatory compliance over the internal systematic identification of all potential hazards, which is the primary goal of HIRA. Option (d) is flawed because while worker consultation is crucial, it should be part of a broader, structured process, not the sole method of hazard identification, and it overlooks the need to analyze the process itself and its interactions. Therefore, a holistic approach that integrates various methods, including expert review, process analysis, and worker input, is essential for effective hazard identification under ISO 45001.

The core of ISO 45001:2018 Clause 6.1.2, concerning hazard identification and risk assessment, mandates that an organization shall establish, implement, and maintain a process for the ongoing identification of hazards, the assessment of risks arising from those hazards, and the identification of opportunities. This process must consider a comprehensive range of factors, including those arising from normal operations, abnormal operations, and emergency situations. Furthermore, it must encompass conditions that could arise from foreseeable human behavior, such as foreseeable misuse. The standard explicitly requires the consideration of hazards arising from the design of workplaces, work systems, processes, installations, machinery, and equipment, as well as organizational factors like work schedules, job rotation, and management styles. It also necessitates the inclusion of hazards arising from changes or proposed changes in the organization, its activities, its products, or its services. The identification of hazards and assessment of risks must also take into account the hierarchy of controls, as outlined in Clause 8.1.2, to determine the most effective measures for elimination or reduction of risks. Therefore, a robust HIRA process must systematically integrate these elements to ensure comprehensive coverage and effective risk management, aligning with the principles of prevention and continuous improvement inherent in the standard.

The core of ISO 45001:2018 clause 6.1.2, concerning hazard identification and risk assessment, mandates a systematic approach to identifying hazards, assessing risks, and determining opportunities. This process is not a one-time event but an ongoing activity that must consider various factors, including changes in the organization’s context, activities, and the introduction of new technologies or substances. The standard emphasizes the need to consider hazards arising from normal, abnormal, and emergency situations. Furthermore, it requires the organization to consider the potential for hazards to arise from foreseeable behavior of persons, including those not directly involved in the work but present in the workplace. The assessment of risks must take into account the likelihood of an event occurring and the severity of the potential harm. Opportunities for improvement are also to be identified alongside risks. The output of this process is crucial for establishing OH&S objectives and planning actions to achieve them, thereby driving the continual improvement of the OH&S management system. Therefore, a comprehensive hazard identification and risk assessment process must encompass a broad spectrum of potential issues, not just those immediately apparent or directly controlled by the organization’s core operations.

The core principle tested here is the systematic integration of legal and other requirements into the hazard identification and risk assessment (HIRA) process as mandated by ISO 45001:2018. Clause 6.1.2, “Hazard identification and risk assessment of risks and opportunities,” specifically requires an organization to establish, implement, and maintain a process for hazard identification and risk assessment. This process must consider legal and other requirements (Clause 6.1.2 a)). Furthermore, Clause 4.3, “Determining the scope of the occupational health and safety management system,” requires the organization to consider external and internal issues that are relevant to its purpose and that affect its ability to achieve the intended outcome(s) of its OHS management system, which explicitly includes legal and other requirements. Therefore, the most effective and compliant approach is to proactively incorporate these requirements into the initial stages of HIRA, ensuring that identified hazards and assessed risks are evaluated against the backdrop of applicable legislation and other commitments. This proactive integration prevents the need for reactive adjustments and ensures that the OHS management system is built on a foundation of compliance and best practice. Ignoring or deferring this integration can lead to non-conformities, potential legal penalties, and a compromised safety culture. The process should involve reviewing relevant legislation (e.g., national health and safety acts, environmental regulations impacting workplace safety), industry standards, and any voluntary commitments the organization has made. This review informs the hazard identification process by highlighting potential risks that are legally mandated to be controlled.

The core principle being tested here is the systematic approach to hazard identification and risk assessment as mandated by ISO 45001:2018, specifically Clause 6.1.2. The scenario describes a manufacturing facility implementing a new automated welding process. The question probes the most appropriate initial step for a HIRA professional to take in this context. ISO 45001 emphasizes a proactive and comprehensive approach. Before any risk evaluation or control measures can be considered, the fundamental hazards associated with the new process must be identified. This involves understanding the nature of the activity, the equipment used, the materials involved, and the potential for exposure to workers. Therefore, the most logical and compliant first action is to systematically identify all potential hazards arising from the introduction of this new automated welding system. This aligns with the iterative nature of HIRA, where identification precedes analysis and evaluation. Other options, while potentially part of the overall HIRA process, are premature as initial steps. For instance, evaluating the effectiveness of existing controls is irrelevant until the hazards of the *new* process are understood. Developing specific control measures without a thorough hazard identification would be a flawed approach, potentially missing critical risks. Similarly, consulting with external regulatory bodies, while important for compliance, is not the *initial* internal step for hazard identification. The standard requires the organization to establish, implement, and maintain a process for the ongoing identification of hazards and assessment of risks.

The core principle being tested here is the iterative nature of hazard identification and risk assessment within an occupational health and safety management system, specifically how changes and new information necessitate a review. ISO 45001:2018, Clause 8.1.2 (Hazard identification and risk assessment of risks) mandates that an organization shall establish, implement, and maintain a process for the ongoing identification of hazards, the assessment of risks, and the determination of controls. This process must consider not only routine operations but also foreseeable emergencies and situations where work is carried out by persons outside the organization. Furthermore, Clause 8.1.3 (Management of change) requires that the organization shall establish a process to implement and control planned changes that affect OH&S performance, including the review of the consequences of unintended changes. When a significant incident occurs, such as a near-miss involving a new chemical substance, it represents new information and a change in the operational context that directly impacts the potential for harm. This necessitates a re-evaluation of existing risk assessments and control measures to ensure their continued effectiveness and to identify any new hazards or risks that may have emerged. The organization must therefore revisit its HIRA process, incorporating the lessons learned from the near-miss to update its understanding of hazards and risks associated with the new chemical, and subsequently revise its controls and procedures. This is not merely about documenting the incident but about proactively improving the safety management system.

No calculation is required for this question as it assesses conceptual understanding of ISO 45001:2018 requirements for hazard identification and risk assessment. The core principle being tested is the proactive and systematic nature of identifying potential sources of harm. Clause 6.1.2 of ISO 45001:2018 mandates that an organization shall establish, implement, and maintain a process for the ongoing identification of hazards, the assessment of risks arising from those hazards, and the identification of opportunities for improvement. This process must consider a wide range of factors, including those arising from normal operations, abnormal operations, emergency situations, and past incidents. It also requires considering the hierarchy of controls and the potential for new hazards to be introduced or existing hazards to change. Therefore, a comprehensive hazard identification process must look beyond immediate dangers and consider the entire lifecycle of activities, products, and services, as well as the context in which the organization operates. This includes anticipating potential failures, human error, and environmental influences that could lead to harm. The emphasis is on a forward-looking approach that aims to prevent incidents before they occur, rather than simply reacting to them. This proactive stance is fundamental to establishing and maintaining an effective occupational health and safety management system.

No calculation is required for this question. The core of effective hazard identification and risk assessment under ISO 45001:2018, particularly when considering the influence of external factors and the organization’s context, lies in a systematic and comprehensive approach. Clause 6.1.2, “Hazard identification and risk assessment of risks and opportunities,” mandates that organizations shall establish, implement, and maintain a process for the ongoing identification of hazards, assessment of risks, and determination of controls. This process must consider the organization’s context (Clause 4.1), the needs and expectations of interested parties (Clause 4.2), and legal and other requirements (Clause 6.1.3). When evaluating the effectiveness of existing controls, a critical step involves verifying that these controls are not only in place but are also functioning as intended and are adequate to mitigate the identified risks. This verification often involves a combination of methods, including inspections, audits, performance monitoring, and feedback from workers. The effectiveness is judged against the established risk criteria and the organization’s ability to achieve its OH&S objectives. A key aspect is understanding that the absence of an incident does not automatically equate to effective control; rather, it’s the proactive assessment of the control’s capability to prevent harm that defines its effectiveness. Therefore, a robust process would involve reviewing the hierarchy of controls and ensuring that higher-level controls (elimination, substitution) are prioritized where feasible, and that lower-level controls (PPE) are used appropriately as a last resort or in conjunction with other measures. The systematic review of the risk assessment process itself, including the methods used for hazard identification and the criteria for risk evaluation, is also crucial for continuous improvement.

The core of ISO 45001:2018’s approach to hazard identification and risk assessment (HIRA) is its emphasis on a proactive and systematic process that considers the entire lifecycle of activities, products, and services. Clause 6.1.2, “Hazard identification and assessment of risks and other opportunities,” mandates that an organization shall establish, implement, and maintain a process for the ongoing identification of hazards, the assessment of risks (and other opportunities) arising from those hazards, and the determination of controls. This process must consider not only normal operating conditions but also foreseeable emergency situations and abnormal situations, including those arising from the reasonably foreseeable behaviour of persons without authorization. Furthermore, it requires consideration of hazards arising from the design of workplaces, systems, processes, plant, equipment, and the organization of work, as well as those arising from changes or proposed changes in the organization, its activities, its products or its services. The standard also stresses the importance of considering the context of the organization, including its interested parties and their needs and expectations, as well as legal and other requirements. Therefore, a comprehensive HIRA process must integrate these elements to effectively manage occupational health and safety (OH&S) risks. The correct approach involves a continuous cycle of identification, assessment, and control, informed by a broad understanding of operational and organizational factors.

The core principle being tested here is the integration of legal and other requirements into the hazard identification and risk assessment (HIRA) process as mandated by ISO 45001:2018. Clause 6.1.2, “Hazard identification and risk assessment of risks and opportunities,” specifically requires an organization to establish, implement, and maintain a process for hazard identification and risk assessment. This process must consider, among other things, “legal and other requirements.” The question probes how an organization should proactively incorporate these external obligations into its HIRA framework. The correct approach involves systematically identifying relevant legal and other requirements and then integrating them into the HIRA methodology, ensuring that these external mandates inform the identification of hazards, the assessment of risks, and the determination of controls. This integration ensures that the organization’s OHS management system is compliant and effective. The other options represent less comprehensive or misdirected approaches. Focusing solely on documented procedures without active integration misses the proactive nature required. Treating legal requirements as a separate compliance exercise rather than a foundational input to HIRA undermines the systematic approach. Finally, relying only on external audits to identify gaps in legal compliance during HIRA is reactive and fails to embed the requirements into the ongoing HIRA process itself.

The core principle being tested here is the systematic approach to hazard identification and risk assessment as mandated by ISO 45001:2018, specifically Clause 6.1.2. The scenario describes a situation where a new chemical process is introduced, which inherently brings new hazards. The organization has a duty to proactively identify these hazards and assess the associated risks before or during the introduction of the process. This involves considering the entire lifecycle of the process, from design and implementation to operation and decommissioning. The standard emphasizes a structured and documented approach. Evaluating existing controls is a crucial step, but it is not the *sole* or *primary* determinant of the initial risk assessment for a novel process. Similarly, relying solely on historical incident data from *different* processes, while potentially informative, is insufficient for a new, distinct hazard. Engaging external consultants is a valid strategy for expertise, but the organization retains ultimate responsibility for the HIRA process. The most comprehensive and compliant approach involves a multi-faceted strategy that includes understanding the process, identifying potential hazards through various methods (e.g., HAZOP, FMEA, checklists), evaluating the risks considering existing and potential controls, and documenting the entire process. This systematic review ensures that all potential risks are considered and managed effectively, aligning with the proactive nature of ISO 45001. The correct approach integrates multiple methods to ensure thoroughness.

The core of ISO 45001:2018 Clause 6.1.2, concerning hazard identification and risk assessment, mandates that an organization shall establish, implement, and maintain a process for the ongoing identification of hazards, the assessment of risks arising from those hazards, and the identification of opportunities for improvement. This process must consider a comprehensive range of factors, including those arising from normal operating conditions, foreseeable abnormal conditions, situations arising in the event of an emergency, and conditions arising from past incidents. Furthermore, it must take into account the potential for human error and the behavior of workers. The identification of hazards should also extend to those arising from the design of workplaces, work systems, plant, equipment, and substances, as well as organizational factors such as work schedules, workload, and management styles. The assessment of risks should consider the severity of potential injury or ill health and the likelihood of it occurring. The objective is to determine the significance of the risks and to inform decisions about the need for controls. Therefore, a systematic approach that encompasses all these elements is crucial for effective HIRA.

The core of effective hazard identification and risk assessment under ISO 45001:2018 lies in a systematic and proactive approach that considers the entire lifecycle of activities and potential changes. Clause 6.1.2, “Hazard identification and assessment of risks and other opportunities,” mandates that an organization shall establish, implement, and maintain a process for the ongoing identification of hazards, the assessment of risks arising from those hazards, and the identification of other opportunities to eliminate hazards or reduce risks to an acceptable level. This process must consider normal operating conditions, foreseeable abnormal conditions, and emergency situations. Furthermore, it must take into account existing controls and their effectiveness.

When evaluating the effectiveness of a hazard identification and risk assessment process, a key indicator is its ability to anticipate potential issues before they manifest as incidents. This involves looking beyond immediate, obvious hazards to consider systemic factors, human behavior, and the interaction of various elements within the work environment. A process that relies solely on past incident data or reactive measures would be considered less robust than one that employs predictive techniques and considers a broader spectrum of potential causes and consequences. The inclusion of worker participation, as emphasized in Clause 5.4, is also crucial, as those closest to the work often possess the most intimate knowledge of potential hazards. The systematic review and updating of the HIRA process, particularly when changes occur (Clause 8.1.3), ensures its continued relevance and effectiveness. Therefore, a process that actively seeks out and addresses potential hazards, even those not yet realized, and integrates worker input, demonstrates a higher level of maturity and compliance with the standard’s intent.

The core principle being tested here is the systematic integration of legal and other requirements into the hazard identification and risk assessment (HIRA) process as mandated by ISO 45001:2018. Clause 6.1.2, “Hazard identification and risk assessment of risks and opportunities,” specifically requires an organization to establish, implement, and maintain a process for hazard identification, risk assessment, and control of risks. This process must consider legal and other requirements relevant to the organization’s context. Furthermore, Clause 6.1.3, “Legal and other requirements,” mandates that the organization shall determine and have access to the legal and other requirements applicable to its hazards and OH&S management system. These identified legal and other requirements must then be taken into account when establishing, implementing, maintaining, and continually improving its OH&S management system, including the HIRA process. Therefore, a robust HIRA process must actively incorporate these external obligations to ensure compliance and effective risk management. The scenario describes a situation where a new chemical substance is introduced, and the organization’s HIRA process needs to ensure that all relevant legal obligations concerning its use, storage, and disposal are identified and integrated into the risk assessment and control measures. This directly aligns with the requirement to consider applicable legal and other requirements when identifying hazards and assessing risks. The other options represent incomplete or misapplied aspects of the standard. Focusing solely on historical incident data (option b) neglects future risks and legal compliance. Prioritizing only employee suggestions (option c) might miss critical regulatory requirements. Implementing controls based solely on the severity of potential harm (option d) without considering legal mandates would be non-compliant and potentially ineffective.

The core principle being tested here is the systematic approach to hazard identification and risk assessment as mandated by ISO 45001:2018, specifically Clause 6.1.2. This clause emphasizes the need for a documented process that considers a wide range of factors, including those arising from normal operations, abnormal conditions, and emergency situations. It also requires the organization to consider hazards arising from the design of safe workplaces and systems, and hazards associated with the introduction of new products, processes, services, and equipment. Furthermore, it mandates consideration of changes in legislation and other requirements, as well as knowledge and information about hazards and risks. The process should also include assessing risks associated with non-conformities and corrective actions, and situations that could arise from foreseeable emergency situations. The question probes the understanding of what constitutes a comprehensive hazard identification and risk assessment process by presenting a scenario where an organization is reviewing its existing system. The correct approach involves a proactive and inclusive methodology that goes beyond simply reacting to incidents. It requires the integration of various inputs to ensure all potential hazards are considered and evaluated. The emphasis on “proactive identification of potential hazards” and “systematic evaluation of risks” aligns directly with the intent of the standard. The inclusion of “consideration of legislative changes” and “review of past incident data” are crucial elements of a robust HIRA process. The concept of “worker participation” is also a cornerstone of ISO 45001, ensuring that those closest to the work contribute their knowledge. Therefore, the approach that integrates these elements represents the most effective and compliant method for hazard identification and risk assessment.

The core principle being tested here is the systematic approach to hazard identification and risk assessment as mandated by ISO 45001:2018, specifically Clause 6.1.2. This clause requires organizations to establish, implement, and maintain a process for hazard identification, risk assessment, and control of risks. The process must consider normal operating conditions, foreseeable abnormal conditions, and situations arising from potential emergencies and accidents. It also emphasizes the need to consider the lifecycle of products and services, including design, development, production, delivery, use, and disposal. The question probes the understanding of how to integrate external factors and the organization’s context into this process. The correct approach involves a comprehensive review that encompasses not only the immediate workplace but also the broader organizational context, including legal and other requirements, and the needs and expectations of interested parties. This holistic view ensures that all potential sources of harm are considered, aligning with the standard’s intent to prevent work-related injury and ill health. The other options represent incomplete or misapplied aspects of the HIRA process. Focusing solely on immediate operational hazards neglects foreseeable abnormal conditions and the influence of external factors. Prioritizing only regulatory compliance overlooks the proactive identification of hazards not explicitly covered by law. Concentrating exclusively on employee-generated hazards limits the scope to a single source, ignoring systemic and environmental influences. Therefore, the most effective and compliant approach is the one that systematically integrates all relevant internal and external factors throughout the lifecycle of activities, products, and services.

The core of this question lies in understanding the iterative and dynamic nature of hazard identification and risk assessment (HIRA) within an ISO 45001:2018 framework, particularly concerning changes. Clause 8.1.2, “Eliminating hazards and reducing risks to occupational health and safety,” mandates that organizations shall establish, implement, and maintain a process for the elimination of hazards and the reduction of OHS risks. This process must consider new hazards and risks arising from changes. When a significant operational change is implemented, such as the introduction of a new automated welding system in a fabrication plant, the existing HIRA is not static. The organization must proactively review and update its HIRA to account for the novel hazards (e.g., increased electrical energy, new fume compositions, potential for robotic malfunction) and associated risks introduced by this change. This review should not be a mere formality but a thorough re-evaluation of the entire process, including the effectiveness of existing controls and the need for new ones. The subsequent monitoring and review of the new system’s performance, including incident data and near misses, feeds back into the HIRA process, ensuring its continued relevance and effectiveness. Therefore, the most appropriate action is to conduct a comprehensive re-evaluation of the HIRA, incorporating the specific changes and their potential impacts, rather than simply documenting the change or relying solely on existing controls without a formal update. The concept of “continual improvement” (Clause 10.3) also underpins this, as the HIRA process itself must be subject to review and enhancement.

The core principle being tested here is the systematic approach to hazard identification and risk assessment as mandated by ISO 45001:2018, specifically Clause 6.1.2. This clause requires organizations to establish, implement, and maintain a process for hazard identification and assessment of risks and opportunities. The process must consider routine and non-routine activities, human factors, and conditions arising from abnormal situations or emergency preparedness. It also emphasizes the need to identify hazards and risks associated with the organization’s products and services provided to interested parties.

The scenario describes a manufacturing facility that has recently introduced a new automated welding robot. The initial HIRA focused on the direct operational hazards of the robot (e.g., arc flash, mechanical pinch points). However, the question probes deeper into the comprehensive nature of hazard identification required by the standard. The introduction of new technology necessitates considering not just the immediate operational risks but also the broader implications. This includes the potential for new, unforeseen hazards arising from the integration of the robot into existing workflows, the interaction between human operators and the automated system, and the maintenance requirements of the new equipment. Furthermore, the standard requires considering the entire lifecycle of activities, including decommissioning or disposal.

A robust HIRA process, aligned with ISO 45001:2018, would proactively seek to identify hazards that might not be immediately apparent during the initial setup or routine operation. This involves engaging a diverse range of personnel, including operators, maintenance staff, engineers, and safety professionals, to leverage their collective knowledge and experience. It also entails reviewing information from similar installations, supplier documentation, and relevant industry best practices. The goal is to move beyond a superficial assessment to a thorough analysis that anticipates potential failure modes, human errors, and environmental factors that could lead to harm.

Therefore, the most effective approach to identify these less obvious hazards is to conduct a systematic review of the robot’s integration, focusing on potential failure modes, human-machine interaction complexities, and the implications for the entire operational lifecycle, including maintenance and potential future modifications. This proactive and holistic perspective ensures that the HIRA process is not merely reactive but truly preventative, aligning with the spirit and requirements of ISO 45001:2018.

The core principle tested here is the iterative nature of hazard identification and risk assessment (HIRA) within an ISO 45001:2018 management system, particularly concerning changes. Clause 8.1.2, “Eliminating hazards and reducing risks to occupational health and safety,” mandates that the organization shall establish, implement, and maintain a process for the elimination of hazards and the reduction of OHS risks. This process must consider new hazards and risks arising from changes, including the introduction of new products, services, and processes, or changes to existing ones. When a significant modification is planned for a chemical handling process, such as introducing a new solvent with different flammability and toxicity characteristics, the organization must proactively reassess the associated hazards and risks. This reassessment is not merely a documentation update but a fundamental step to ensure that controls remain effective or are enhanced to manage the altered risk profile. The process should involve identifying the specific changes, evaluating the potential new hazards (e.g., increased vapor concentration, new exposure routes), assessing the risks associated with these hazards using the established methodology (e.g., likelihood and severity), and then determining and implementing appropriate control measures. This is a proactive measure to prevent incidents before they occur, aligning with the Plan-Do-Check-Act cycle inherent in ISO management systems. The emphasis is on anticipating and managing risks arising from modifications, rather than reacting to incidents. Therefore, the most appropriate action is to conduct a comprehensive HIRA for the modified process before its implementation.

The core principle being tested here is the proactive nature of hazard identification and risk assessment under ISO 45001:2018, specifically concerning the integration of new or changed activities. Clause 8.1.2, “Eliminating hazards and reducing risks to occupational health and safety,” mandates that the organization shall establish, implement, and maintain a process for the continual improvement of the OH&S management system, including hazard identification and risk assessment of *all* hazards associated with *all* activities under its control. This includes planned and unplanned changes. When introducing a new chemical substance, the organization must ensure that the hazard identification and risk assessment process is applied *before* the substance is introduced into the workplace. This involves understanding the chemical’s properties, potential exposure routes, health effects, and the necessary control measures (e.g., ventilation, personal protective equipment, safe handling procedures, emergency response plans). Failing to conduct this assessment prior to introduction means the organization has not adequately planned for the potential risks, thereby contravening the intent and requirements of the standard. The process is not merely reactive; it’s about anticipating and mitigating risks before they materialize. Therefore, the most appropriate action is to conduct a comprehensive HIRA *before* the chemical is brought into use.

The core principle being tested here is the iterative and dynamic nature of hazard identification and risk assessment (HIRA) within an ISO 45001:2018 framework, particularly concerning changes in work activities. ISO 45001:2018, Clause 8.1.2, mandates that organizations shall establish, implement, and maintain a process for hazard identification and risk assessment of operational activities. This process must consider not only routine operations but also non-routine work, changes in work, and situations outside the organization’s immediate control that could introduce new hazards or increase existing risks. When a significant change is introduced, such as the adoption of a new chemical substance with unknown long-term health effects, the existing HIRA process must be re-engaged. This re-engagement is not merely a review but a proactive re-evaluation to identify new hazards, assess the associated risks, and determine appropriate controls before the change is fully implemented or to manage it effectively if it’s already underway. The emphasis is on preventing the introduction of new risks or exacerbation of existing ones due to the change. Therefore, the most appropriate action is to initiate a comprehensive re-assessment of all identified hazards and risks related to the new substance, ensuring that the control measures are adequate for the new circumstances. This aligns with the Plan-Do-Check-Act cycle inherent in management systems and the proactive risk management philosophy of ISO 45001.

No calculation is required for this question. The core of effective hazard identification and risk assessment under ISO 45001:2018 lies in a systematic and comprehensive approach that considers all relevant factors. Clause 6.1.2, “Hazard identification and risk assessment of risks,” mandates that organizations identify hazards, assess risks, and determine controls. This process should be ongoing and proactive, not merely reactive. It requires considering not only routine operations but also non-routine activities, emergency situations, and the potential for foreseeable abnormal situations. Furthermore, the standard emphasizes the involvement of workers and other relevant persons in this process, as they often possess direct knowledge of hazards and risks in their work environment. The identification of hazards must also extend to the potential impacts on workers, visitors, and any other persons who could be exposed to risks arising from the organization’s activities. This includes considering the design of workplaces, the selection and use of work equipment, the properties of substances used, and the organizational factors that can influence exposure. A robust HIRA process integrates these elements to ensure that all significant hazards are identified and that risks are adequately controlled, thereby preventing work-related injury and ill health.

The core principle of ISO 45001:2018, particularly concerning hazard identification and risk assessment (HIRA), is the proactive identification and control of risks to prevent work-related injury and ill health. Clause 6.1.2, “Hazard identification and assessment of risks and other hazards,” mandates that an organization shall establish, implement, and maintain a process for the ongoing identification of hazards, the assessment of risks arising from those hazards, and the identification of opportunities for improvement. This process must consider a wide range of factors, including those arising from normal operating conditions, abnormal conditions, and emergency situations. It also requires consideration of hazards arising from the design of workplaces, work systems, processes, plant, equipment, and substances, as well as organizational factors such as workload, working hours, and management styles. Furthermore, the standard emphasizes the importance of worker participation in this process. The question probes the fundamental purpose of the HIRA process within the ISO 45001 framework, which is to systematically uncover potential sources of harm and evaluate their likelihood and severity to implement effective controls. The correct approach focuses on the overarching goal of preventing harm and improving OH&S performance. Incorrect options might focus on secondary outcomes, specific control measures without addressing the primary identification and assessment purpose, or misinterpret the proactive nature of the standard. The emphasis is on the systematic and ongoing nature of identifying and evaluating potential harm to workers.

No calculation is required for this question as it assesses conceptual understanding of ISO 45001:2018 requirements for hazard identification and risk assessment. The standard mandates that an organization shall establish, implement, and maintain a process for the ongoing identification of hazards, the assessment of risks arising from those hazards, and the identification of opportunities for improvement. This process must consider a wide range of factors, including those arising from normal operations, abnormal operations, and emergency situations. It also requires consideration of hazards and risks associated with the design of new facilities, products, and services, as well as changes to existing ones. Furthermore, the standard emphasizes the importance of consulting with workers and their representatives in this process. The effectiveness of the hazard identification and risk assessment process is directly linked to the organization’s ability to prevent work-related injury and ill health. Therefore, a comprehensive approach that systematically considers all potential sources of harm, including those that may not be immediately obvious or that arise from interactions between different elements of the workplace, is crucial. This includes looking beyond immediate physical hazards to consider psychosocial factors, ergonomic issues, and the impact of organizational changes. The goal is to proactively manage risks and create a safer working environment, aligning with the core principles of occupational health and safety management systems.
