ISO 45001 is an international standard that specifies requirements for an occupational health and safety management system (OHSMS). It provides a framework for organizations to establish, implement, maintain, and continually improve their occupational health and safety performance. The main goal of OHSMS is to provide a safe and healthy workplace for employees and others affected by an organization's activities.

To obtain ISO 45001 Certification, an organization needs to undergo a certification audit conducted by an accredited certification body. The audit assesses the organization's compliance with the standard's requirements and its effective implementation of the OH&S management system. Once the organization meets all the necessary criteria, it is awarded this certification, demonstrating its commitment to providing a safe and healthy work environment.

OHSMS certification offers several benefits, including improved safety performance, enhanced reputation, better risk management, and increased confidence among stakeholders, including customers, employees, and regulatory authorities.

Improved Occupational Health and Safety Performance: ISO 45001 provides a systematic approach to identifying workplace hazards, assessing risks, and implementing appropriate controls. By focusing on the prevention of accidents, injuries, and ill-health, the standard helps organizations create a safer and healthier work environment for employees.

Hazard Identification and Risk Assessment: The standard requires organizations to identify workplace hazards, assess associated risks, and implement controls to mitigate these risks.

Legal Compliance: Ensures that organizations comply with relevant health and safety laws, regulations, and other requirements. By staying compliant, organizations can avoid penalties, fines, and legal issues related to workplace safety.

Objectives and Performance Monitoring: Organizations are expected to set health and safety objectives, monitor their performance, and take corrective actions as necessary.

Employee Participation: ISO 45001 encourages employee involvement in the OH&S management system, as they are often best placed to identify potential hazards and suggest improvements.

Management Leadership and Commitment: The standard emphasizes the importance of top management's commitment to the OH&S management system and ensuring it is integrated into the organization's overall business processes.

Continual Improvement: Organizations are required to continually improve their OH&S performance by evaluating the effectiveness of their management system and making necessary enhancements.

ISO 45001 is applicable to organizations of all sizes and industries, and it can be integrated with other management system standards, such as ISO 9001 (Quality Management) and ISO 14001 (Environmental Management).

URS is a global certification body that provided certification services for various management system standards, including ISO 45001 for occupational health and safety management system. However, it's important to note that the information might have changed since then, as companies can rebrand, merge, or change their services over time. URS currently offers ISO OHSMS certification or to get more up-to-date information about their services, I recommend visiting their official website or contacting them directly for the most accurate and current details.
