Quick Answer

ISO 45001 is the international standard for an occupational health and safety management system. It gives organisations a structured way to prevent work-related injury and ill health and to improve safety over time. Certification is audited, and routine inspections, hazard reporting, and corrective actions keep a business aligned to it.

What is ISO 45001?

ISO 45001 is the international management-system standard for occupational health and safety. It sets out how an organisation should identify hazards, control risks, and protect the health and safety of workers and anyone affected by its activities.

The standard emphasises leadership, worker participation, and a risk-based approach, and it expects continual improvement rather than a fixed checklist. It replaced the earlier OHSAS 18001 and can be certified by an external body.

What ISO 45001 requires in practice

In practice, ISO 45001 expects an organisation to assess its health and safety risks, put controls in place, involve workers, and monitor whether the controls are working. It asks for incident reporting, inspections, internal audits, and corrective action.

Day to day, the evidence comes from safety inspections, hazard reports, and records of issues resolved. A finding on a safety walk should become a tracked corrective action, which is what auditors and safety regulators expect to see.

How Inspectly360 supports ISO 45001

Inspectly360 digitises the safety inspections and hazard reporting that ISO 45001 relies on. Safety walks, equipment checks, and audits run as mobile checklists with photo evidence and timestamps, and workers can report hazards from the field.

A failed check or reported hazard raises a corrective action with an owner and a deadline, and managers track open risks across every site on one dashboard. See the safety audit software to run these checks and keep an audit-ready record.

Frequently Asked Questions

What is ISO 45001 in simple terms?

ISO 45001 is an international standard that describes how to manage health and safety at work so that people are not hurt or made ill by their jobs. In simple terms, it asks an organisation to find the hazards in its activities, put sensible controls in place, involve workers in the process, and keep checking that the controls actually work. It is a management system rather than a rulebook of specific fixes, so it applies to an office, a factory, a construction site, or a hospital alike. The aim is to build safety into how the organisation runs every day, and to keep improving, rather than reacting only after an accident happens.

How is ISO 45001 different from OSHA?

ISO 45001 is a voluntary international management standard, while OSHA refers to occupational safety regulation and enforcement in the United States. ISO 45001 describes how to build and run a health and safety management system that any organisation in any country can adopt and be certified against. OSHA sets legally binding workplace safety requirements and inspects and penalises employers who fail to meet them within its jurisdiction. The two are complementary: an organisation that runs a strong ISO 45001 system is usually well placed to meet regulatory duties such as OSHA, because both rely on the same foundations of hazard identification, control, records, and corrective action.

Who should implement ISO 45001?

Any organisation that wants to reduce work-related injury and ill health can implement ISO 45001, and it is especially valuable where risks are significant, such as construction, manufacturing, logistics, energy, and healthcare. Larger organisations often adopt it to demonstrate duty of care to workers, regulators, and clients, and some customers require it before awarding contracts. Smaller businesses use it to bring structure to safety that might otherwise depend on one person's diligence. Because worker participation is a core theme, it works best when the people doing the job are involved in spotting hazards and shaping controls, rather than safety being treated as a document owned only by management.

What does an ISO 45001 audit check?

An ISO 45001 audit checks that the health and safety management system is well designed and genuinely working. Auditors review the hazard identification and risk assessments, confirm that controls are in place and monitored, and look at how workers are involved and consulted. They examine records of inspections, incidents, and corrective actions, and they check that findings lead to real improvement rather than being logged and forgotten. As with other standards, they want live evidence, so safety inspection records, hazard reports, and sign-offs must be complete and consistent. An organisation that captures this digitally, with photos and timestamps, can show control far more convincingly than one relying on paper forms.

How does Inspectly360 support ISO 45001?

Inspectly360 supports ISO 45001 by digitising the safety inspections, hazard reporting, and corrective actions the standard depends on. Safety walks, equipment checks, and audits run as mobile checklists with photo evidence and timestamps, and workers can raise a hazard from the field on their phone, which supports the standard's emphasis on participation. When a check fails or a hazard is reported, the app creates a corrective action with an owner and a deadline, then tracks it to closure. Managers see open risks and overdue actions across every site on one dashboard, and audit-ready reports are generated automatically, so demonstrating control during an audit becomes straightforward.
