Another Safety Management Standard? Sorting out the NEW ISO 450001

May 29, 2018

You may have heard that the ISO has recently released ISO 45001 titled, “Occupational Health and Safety Management System.”  The standard blends safety management systems such as ANSI/ASSE Z10 and OHSAS 18001 into a new globally acceptable management standard.


ISO 45001 will replace OHSAS 18001, a British standard; so what are the major differences between OHSAS 18001 and ISO 45001? The main change is that ISO 45001 concentrates on the interaction between an organization and its business environment while OHSAS 18001 was focused on managing OH&S hazards.   The table below illustrates some of the differences between the two standards: 





















Process Based                                                                           Procedures Bases

Dynamic Systems are Revised as Necessary                                  Not Dynamic

Deals with both Risk and Opportunities for Improvement               Deals only with Risk

Includes many Stakeholders                                                       Focuses on the Procedures


ISO 45001 also encourages OH&S to be an integrated part of an organization and not a separate function or division.


The ANSI/ASSE Z-10 standard addressed many of the same issues as ISO 45001.  However, the ANSI/ASSE Z-10 standard was primarily developed for U.S. based companies.  The ANSI/ASSE Z-10 standard also contained more information regarding how the standard should be implemented; something which ISO 45001 does not address. The ANSI/ASSE Z-10 standard committee is looking at what type of a role the standard should fulfill given the new ISO 45001 standard.  Most experts agree that the two standards can certainly complement each other given that ISO 45001 is very process based with the ANSI/ASSE Z-10 standard having much more detail and specifics.
