All organizations, regardless of their size or complexity are faced with the challenge of implementing an occupational safety and health (OH&S) management system that would prevent injuries and ill health to persons that are working under the control of the organization (contractors, employees). The Occupation Health and Safety Assessment Series (OHSAS) 18001 standard has been successfully adopted by many organizations to manage their (OH&S) hazards and risks.
OHSAS 18001 is a standard that specifies how an occupational safety and health management system should be designed. The standard provides a framework for organizations, regardless of their complexity or size, to holistically manage their occupational safety and health risks though a simple PLAN-DO-CHECK-ACT system of management. This management model is found in other management system standards such as ISO 9001 and ISO 14001. Therefore organizations have found it convenient to integrate OHSAS 18001 into their existing ISO 9001 and/or ISO 14001 systems.
