Independent UK Certification Body

Occupational Health & Safety Certification

ISO 45001:2018 sets out requirements for an Occupational Health & Safety (OH&S) management system, helping organisations prevent work-related injury and ill health and proactively improve workplace safety performance. International Assessment Bureau carries out independent, impartial audits against the standard and issues certification that gives your workforce, customers and regulators confidence in how you manage safety risk.

People die every day worldwide from work-related accidents or disease, according to the International Labour Organisation – the reason ISO 45001:2018 was developed as a single, internationally agreed framework for managing workplace health and safety.

The Standard

What ISO 45001:2018 Certification Covers

Proactive Prevention

Focuses on preventing work-related injury and ill health rather than simply reacting once something has gone wrong.

Worker Participation

Takes the needs and expectations of workers and other interested parties into account when managing OH&S risk.

Annex SL Structure

The first OH&S standard built fully to the common Annex SL framework, so it integrates cleanly with ISO 9001 and ISO 14001.

Universally Applicable

Suitable for organisations of any size and sector - large or small, private, public or non-profit.

Why It Matters

What ISO 45001:2018 Does For Your Organisation

Reduces incidents: systematic identification and control of workplace hazards before they cause harm.
Lowers costs: fewer accidents mean less downtime, lower insurance premiums and reduced liability.
Wins more business: many clients and tenders require evidence of a certified OH&S management system.
Builds trust: demonstrates to your workforce and regulators that safety is managed, not assumed.
Keeps you current: annual surveillance audits ensure the system - and your certificate - stays live and credible.

Background

About ISO 45001:2018

International Assessment Bureau is an independent certification body based in the UK. ISO 45001:2018 does not set out detailed OH&S performance criteria, and it does not prescribe the design of your management system - it gives you a structured framework that can be tailored to organisations of any size, sector or risk profile, from small contractors to large multinational employers.

ISO itself issues no certification or conformity test directly - it develops the standards through a consensus-based process involving technical committees, industry experts, consumer organisations and national standards bodies. Certification against ISO 45001:2018 is carried out by certification bodies such as International Assessment Bureau.
