ISO 45001
ISO 45001 Occupational Health and Safety
Safer, healthier workplaces for workers and visitors.

ISO 45001 specifies the requirements for an occupational health and safety management system, with guidance for its use, so that organisations can provide safe and healthy workplaces and prevent work-related injury and ill health.
It replaced the earlier OHSAS 18001 specification. It puts strong emphasis on leadership, worker consultation and participation, and on eliminating hazards and reducing OH&S risks.

FAQ
Frequently asked questions
What happened to OHSAS 18001?+
OHSAS 18001 was replaced by ISO 45001, and organisations certified to it had a transition period to move to the new standard. ANAP lists ISO 45001 as its current scheme.
Does certification guarantee a zero-accident workplace?+
No. It shows that a system is in place to identify hazards, control risks and improve, and that it is audited by an independent body.
