Tips for Passing the IOSH Managing Safely Assessment

The IOSH Managing Safely assessment tests your understanding of practical health and safety management. Here are proven strategies to help you pass:

Candidates can also sharpen their skills with our ISAT practice test 2026, which includes hundreds of practice questions in the exact format and difficulty of the real exam.

• Understand COSHH thoroughly — know what COSHH stands for, the COSHH symbols, and how to carry out a COSHH assessment. These topics frequently appear in the assessment.
• Learn the Health and Safety at Work Act 1974 (HASAWA) — understand employer and employee duties, and how it relates to the Management of Health and Safety at Work Regulations 1999.
• Master the 5 steps of risk assessment — this is the foundation of the IOSH course and essential for both the MCQ test and the risk assessment project.
• Know the hierarchy of control — from elimination to PPE, understand when each control measure is appropriate.
• Practice with our free tests — use the IOSH Managing Safely practice tests above to familiarise yourself with the question format.

According to Institution of Occupational Safety and Health, “Delegates who successfully complete the written and practical assessments receive IOSH’s Managing Safely certificate.”^[1]

IOSH content outline and where to practise each area

The content areas below are copied from the official IOSH content outline published by Institution of Occupational Safety and Health. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through IOSH questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: What evidence should be included to support the risk assessment findings?

1. No evidence is needed — professional judgement is sufficient
2. Photographs, workplace observations, accident data, worker feedback, manufacturer's guidance, and relevant legislation references
3. Only witness statements from workers
4. Only copies of the safety policy

Answer: B. Photographs, workplace observations, accident data, worker feedback, manufacturer's guidance, and relevant legislation references

Explanation:

Correct answer: B. A risk assessment is only as reliable as the evidence behind it. Photographs and observation notes record conditions as you found them. Accident and near-miss data show what has already gone wrong. Feedback from workers shows how the work really gets done. Manufacturer's guidance and references to legislation show which standard you measured against.

Why the others are wrong: A is wrong because judgement on its own cannot be checked or reviewed. C is too narrow, because witness statements are useful but leave out physical and documentary evidence. D is wrong because the safety policy states intentions and says nothing about the conditions you actually found.

Rule to remember: support your findings with several kinds of evidence, so that someone else could check how you reached your conclusion.

Example 2

Question: Which occupational disease is directly caused by prolonged inhalation of respirable crystalline silica dust?

1. Asbestosis
2. Silicosis
3. Mesothelioma
4. Occupational asthma

Answer: B. Silicosis

Explanation:

Correct answer: B, silicosis. Silicosis is scarring (fibrosis) of the lungs caused by breathing in fine crystalline silica dust. This dust is produced when stone, concrete and similar materials are cut, drilled or quarried.

Why the others are wrong: A and C are both caused by asbestos fibres, not silica. Asbestosis is lung fibrosis caused by asbestos, and mesothelioma is a cancer of the lining around the lungs that is also linked to asbestos. D, occupational asthma, is caused by breathing in sensitisers such as flour dust, isocyanates or wood dust. It is not the scarring disease that silica causes.

Rule to remember: learn each disease alongside the substance that causes it. Silica causes silicosis, and asbestos causes asbestosis and mesothelioma. Exam questions often place these pairs next to each other.

Example 3

Question: What are the most common causes of workplace injuries in the UK?

1. Chemical exposure and radiation
2. Slips, trips and falls, manual handling injuries, and being struck by objects
3. Only machinery-related injuries
4. Only injuries from working at height

Answer: B. Slips, trips and falls, manual handling injuries, and being struck by objects

Explanation:

Correct answer: B. HSE statistics for the UK show that most reported workplace injuries come from ordinary, everyday activities. Slips, trips and falls are the single biggest cause, followed by manual handling and being struck by moving objects.

Why the others are wrong: A names real hazards, but chemical exposure and radiation affect fewer workers and are not among the most common causes of injury. C and D both use the word "only". Machinery and work at height do cause serious injuries, but neither one accounts for all injuries.

Rule to remember: the most common injuries usually come from routine tasks, not dramatic ones. Be wary of any answer that says "only", because a single cause is rarely the full picture in safety questions.

How to use these practice tests

Before the course: take the introductory practice test without studying first. Note the topics where you struggled. That gives you a list to listen out for when the trainer covers them.

During the course: on each evening, take the practice set that matches what you covered that day. For example, take Understanding Responsibilities after the session on responsibilities, and Assessing Risks and Controlling Risks after the sessions on risk. For every question you get wrong, write down the rule behind the right answer, not just the letter.

For the practical assessment: the practical assessment asks you to apply what you have learned in a real workplace. Use the Project Work set to practise spotting hazards, judging risk and proposing controls. Ask your trainer what format they expect for the practical, and stick to it.

Before the written assessment: go back over your list of wrong answers and retake the Investigating Incidents and Measuring Performance sets. Treat the course workbook from your provider as the main source. Use these quizzes to check that you understood it.

Understanding COSHH in the IOSH Managing Safely Course

COSHH (Control of Substances Hazardous to Health) is one of the most important topics in the IOSH Managing Safely course. As a manager, you need to understand what COSHH stands for, how to identify COSHH symbols, and how to conduct COSHH assessments.

The COSHH Regulations 2002 require employers to assess and control exposure to hazardous substances. COSHH symbols are the standardised GHS pictograms found on product labels — including corrosive, toxic, flammable, and oxidising symbols. Understanding these symbols is essential for any manager completing the IOSH course.

Health and Safety at Work Act and Key Legislation

The Health and Safety at Work Act 1974 (HASAWA) is the cornerstone of UK health and safety law. It places a duty on employers to ensure, so far as is reasonably practicable, the health, safety, and welfare of all employees. The Management of Health and Safety at Work Regulations 1999 expand on these duties, requiring employers to carry out risk assessments and appoint competent persons.

Other key legislation covered in the IOSH Managing Safely course includes RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations), PUWER (Provision and Use of Work Equipment Regulations), and the Manual Handling Operations Regulations 1992.
