The OHSAS 18001 standard is becoming the ISO 45001


OHSAS 18001, Occupational Health and Safety Assessment Series is an internationally applied standard for occupational health and safety management systems. It exists to help organizations put in place demonstrably sound occupational health and safety performance. This standard is now being updated and replaced by the ISO (International Standards Organisation) 45001 which looks to apply the high level structure of the ISO to the OHSAS.

The ISO 45001 was released in Q1 2018, this integration and standardisation makes it easier for businesses and employees by providing compatibility between key ISO standards such as the ISO 9001 & 14001.
