OHSAS 18001 Certification
OHSAS 18001, Occupational Health and Safety Assessment Series, was an international standard for occupational health and safety management systems. It was adopted as a British Standard. This standard required organizations to maintain a management system to ensure health safety in the workplace.
OHSAS 18001 was withdrawn and replaced by ISO 45001, published by International Organization for Standardization in March 2018. All organization certified to OHSAS 18001 migrated to ISO 45001 by March 2021.
