OHSAS 18001, Occupational Health and Safety Assessment Series, (officially BS OHSAS 18001) is an internationally applied British Standard for occupational health and safety management systems. It exists to help all kinds of organizations put in place demonstrably sound occupational health and safety performance. It is a widely recognized and popular occupational health and safety management system.
OHSAS 18001 is an international standard which sets out the requirements for occupational health and safety management good practice for any size of organization. It provides guidance to help companies/organizations design their own health and safety framework – allowing them to bring all relevant controls and processes into one management system.
BS OHSAS 18001 can also be adapted to all types of organizations to help eliminate or minimize operational risks and hazards. The standard is designed to help companies/organizations create the best possible working conditions in their organization – helping them to meet legal, industry and customer requirements.
BS OHSAS 18001 specifies requirements for an OH&S management system to help an organization develop and implement a policy and objectives, which take into account legal requirements and information about OH&S risks. It applies to all types and sizes of organizations and accommodates diverse geographical, cultural and social conditions.
BS OHSAS 18002 provides guidance for establishing, implementing or improving a management system which is based on OHSAS 18001 and demonstrating successful implementation of OHSAS 18001.
OHSAS 18001 can be aligned with existing ISO 9001 and ISO 14001 management systems. Historically many organizations start with the quality management system ISO 9001, then add the environment management requirements from ISO 14001. Many organizations now look at implementing all three standards at once which can minimize costs and disruption.
In comparison to standards like SA 8000 and BSCI, OHSAS has a more narrow focus on health and safety versus the broader approach of social accountability.
BSI Group offers multiple guides, manuals and training courses on the standard.
