Please note – CSA Z45001:19, Occupational health and safety management systems – Requirements with guidance for use, is the National Standard of Canada, and CSA Z1000:14, Occupational health and safety management is an active standard; however, during the next systematic review by the Technical Committee in 2024, CSA Z1000 will be proposed for withdrawal. CSA Preface This is the first edition of CSA Z45001, Occupational health and safety management systems — Requirements with guidance for use, which is an adoption, with Canadian deviations, of the identically titled ISO (International Organization for Standardization) Standard 45001 (first edition, 2018-03). For brevity, this Standard will be referred to as \"CSA Z45001\" throughout. Organizations are accountable for occupational health and safety and workplace parties are responsible for health and safety within their respective control or authority. This Standard provides a model for establishing, implementing, and maintaining an occupational health and safety management system that encourages a systematic approach to meeting defined occupational health and safety objectives and increases awareness of health and safety in the workplace. This Standard can also assist organizations seeking certification under federal, provincial, and sector-based certification programs (e.g., Certificates of Recognition). The original ISO 45001 standard was developed by an international committee. Based on a survey of stakeholders from across Canada, CSA Group concluded that while ISO 45001 is both comprehensive and strong, Canadian organizations would benefit from adoption of the ISO standard with deviations that reflect the Canadian context of health and safety. As a fundamental concept, and to identify the inclusiveness of an occupational health and safety management system, this Standard defines \"occupational health and safety\" as the promotion in the workplace of the physical, mental, and social wellbeing of workers and the protection of workers from, and the prevention of, workplace conditions and factors adverse to their health and safety. This Standard was reviewed to align with the CSA Group Z1000 series of Standards on occupational health and safety management, including the following: • CSA Z1000-14, Occupational health and safety management; • CAN/CSA-Z1001-18, Occupational health and safety training; • CAN/CSA-Z1002-12, Occupational health and safety — Hazard identification and elimination and risk assessment and control; • CAN/CSA-Z1003-13, Psychological health and safety in the workplace; • CSA Z1004-12, Workplace ergonomics — A management and implementation standard; • CSA Z1005-17, Incident investigation; • CSA Z1006-16, Management of work in confined spaces; • CSA Z1007-16, Hearing loss prevention program (HLPP) management; • CSA Z1010-18, Management of work in extreme conditions; and • CSA Z1600-17, Emergency and continuity management program. Significant deviations were made to ISO 45001 to meet the following objectives: a) to translate international terminology and expressions to occupational health and safety (OHS) terminology recognized in Canada; b) to modify the fundamental process for risk assessment and risk control to emphasize the elimination of hazards in accordance with CSA Z1000 and CAN/CSA-Z1002; c) to recognize workers’ rights to remove themselves from hazardous situations; d) to recognize the role of worker representatives in determining the OHS needs of workers; e) to recognize the requirement to ensure that workers and worker representatives participate in OHS management decision making; and f) to recognize that required PPE and training must be ensured by the organization. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This document specifies requirements for an occupational health and safety (OH&S) management system, and gives guidance for its use, to enable organizations to provide safe and healthy workplaces by preventing work-related injury and ill health, as well as by proactively improving its OH&S performance. This document is applicable to any organization that wishes to establish, implement and maintain an OH&S management system to improve occupational health and safety, eliminate hazards and minimize OH&S risks (including system deficiencies), take advantage of OH&S opportunities, and address OH&S management system nonconformities associated with its activities. This document helps an organization to achieve the intended outcomes of its OH&S management system. Consistent with the organization’s OH&S policy, the intended outcomes of an OH&S management system include: a) continual improvement of OH&S performance; b) fulfilment of legal requirements and other requirements; c) achievement of OH&S objectives. This document is applicable to any organization regardless of its size, type and activities. It is applicable to the OH&S risks under the organization’s control, taking into account factors such as the context in which the organization operates and the needs and expectations of its workers and other interested parties. This document does not state specific criteria for OH&S performance, nor is it prescriptive about the design of an OH&S management system. This document enables an organization, through its OH&S management system, to integrate other aspects of health and safety, such as worker wellness/wellbeing. This document does not address issues such as product safety, property damage or environmental impacts, beyond the risks to workers and other relevant interested parties. This document can be used in whole or in part to systematically improve occupational health and safety management. However, claims of conformity to this document are not acceptable unless all its requirements are incorporated into an organization’s OH&S management system and fulfilled without exclusion.
