There
are many differences, but 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 and other internal issues. But
the standards also diverge in many other ways:ISO 45001 is process-based –
OHSAS 18001 is procedure-based
ISO
45001 is dynamic in all clauses – OHSAS 18001 is not
ISO
45001 considers both risk and opportunities – OHSAS 18001 deals exclusively
with risk
ISO
45001 includes the views of interested parties – OHSAS 18001 does not
These
points represent a significant shift in the way health and safety management is
perceived. OH&S is no longer treated as a “stand aloneâ€, but must be viewed
within the perspective of running a sound and sustainable organization. That
being said, although the two standards differ in their approach, a management
system established in accordance with OHSAS 18001 will be a solid platform for
migrating to ISO 45001.
Structure: The structure of ISO 45001 is
based on Annex SL, which is the framework used in other ISO management system
standards, making implementation easier and more efficient
Management Commitment: ISO 45001 requires the
incorporation of health and safety into the overall management system of the
organization, requiring management to take a stronger leadership role in
OH&S.
Worker Involvement: ISO 45001 requires employee
training and education to identify risks and help create a successful safety
program, allowing broader employee participation
Risk v. Hazard: ISO 45001 follows a preventative process, requiring hazard risks to be evaluated and remedied before they cause accidents and injuries, unlike OHSAS 18001, which focused only on hazard control.
