OHSAS 18001:2007 Occupational Health & Safety Management System (OHSMS)
OHSAS 18001 is the internationally recognized assessment specification for occupational health and safety management systems. National bodies like BSI, ANSI. BIS and others have developed standard based on these specifications or on their own.
An Occupational Health and Safety Management System (OHSMS) is a framework that allows an organization to consistently identify and control its
- health and safety risks,
- reduce the potential for accidents,
- help achieve compliance with health and safety legislation and
- Continually improve its Performance.
OHSAS 18001 is an internationally accepted specification that defines the requirements for establishing, implementing and operating an OHSMS. The specification was developed with the assistance of a number of international standards bodies and certification bodies. OHSAS 18001 fills a void, in that there is currently no international ISO standard suitable for independent third-party certification.
The following key areas are addressed by OHSAS 18001:
- health & Safety hazard identification,
- Risk Framework, Risk mitigation control
- OHSMS programme
- Training, awareness and competence Building
- Operational control
- Emergency preparedness and response
- Measurement of organizational performance in respect to Health & Safety
This Occupational Health and Safety Assessment Series (OHSAS) Standard specifies requirements for an occupational health and safety (OH&S) management system, to enable an organization to control its OH&S risks and improve its OH&S performance. It does not state specific OH&S performance criteria, nor does it give detailed specifications for the design of a management system.
This OHSAS Standard is applicable to any organization that wishes to:
- establish an OH&S management system to eliminate or minimize risks to personnel
and other interested parties who could be exposed to OH&S hazards associated
with its activities;
- implement, maintain and continually improve an OH&S management system;
- assure itself of its conformity with its stated OH&S policy;
- demonstrate conformity with this OHSAS Standard by:
- making a self-determination and self-declaration, or
- seeking confirmation of its conformance by parties having an interest in the organization,
such as customers, or
- seeking confirmation of its self-declaration by a party external to the organization,
- seeking certification/registration of its OH&S management system by an external
The level of detail and complexity of the OH&S management system, the extent of documentation and the resources devoted to it depend on a number of factors, such as the scope of the system, the size of an organization and the nature of its activities, products and services, and the organizational culture. This may be the case in particular for small and medium-sized enterprises.
