IOSH Managing Safely is one of the most widely recognised health and safety qualifications for managers, supervisors, team leaders and anyone with responsibility for people or processes. The course is designed to help those in leadership roles to:
Understand their legal responsibilities
Improve risk assessment and risk management competence
Create safer systems of work
Reduce workplace accidents and incidents
Manage health and safety proactively, not reactively
It is suitable for any industry and requires no previous health and safety qualifications. If you're reviewing risk controls in your organisation, our Safe Systems of Work FAQ explains how structured procedures help prevent incidents and support compliance. For a closer look at how IOSH approaches likelihood, severity and control, you can read our explanation of IOSH risk ratings and practical risk management.
The exact syllabus depends on the IOSH-approved training provider, but it typically includes:
Introducing Managing Safely
Assessing Risks (risk assessment principles and practical tools)
Controlling Risks (risk control hierarchy, controls, safe systems)
Understanding Responsibilities (legal duties and employer obligations)
Understanding Hazards (common workplace hazards and how to manage them)
Investigating Incidents (accident causation and reporting)
Measuring Performance (audits, inspections, KPIs)
These themes lay the foundation for risk management responsibilities essential for any manager. For a deeper look at the management principles behind IOSH training, read our guide to the Plan, Do, Check, Act model and how it supports continuous improvement. Or for more information about how to measure performance and track improvements, our guide to health and safety KPIs outlines the most effective indicators for monitoring risk and compliance.

Yes. IOSH training is available:
Online (self-paced or virtual classroom)
In person (classroom training)
Blended (mix of both)
An IOSH Managing Safely online course provides flexibility, while classroom delivery may suit teams or those who prefer live instruction.
Ensure your provider is an IOSH-approved training provider.
Assessment usually includes:
Multiple-choice knowledge test
Practical risk assessment project completed in the learner’s workplace or a simulated environment
Both must be passed to receive the IOSH certificate. For learners taking the Commodious IOSH Managing Safely online course, the assessment is divided into two parts:
A 30-question multiple-choice test, completed online in one sitting. You’ll have one hour, and it’s taken as a closed-book exam.
A practical risk assessment project, completed in your own workplace and marked against IOSH’s criteria.
You’ll complete the course modules first, then move on to the assessment when you feel ready. Both parts need to be passed to receive your IOSH certificate, and you have three months from starting the course to complete them. If things don’t go to plan the first time, our team can reset the course free of charge, giving you another opportunity to work through the material and try again.
If you’d like help preparing for the project element of the qualification, our IOSH Managing Safely practical risk assessment guide walks through the process step by step.
