When Should You Take An IOSH Managing Safely Refresher Course?

The IOSH Managing Safely course helps managers and supervisors understand their health and safety responsibilities, identify workplace hazards and manage risks effectively. But completing the course once doesn’t mean your knowledge will always stay up to date. 

An IOSH Managing Safely refresher course can help you revisit key principles and maintain confidence in managing workplace safety. So, when should you take a refresher, and how can you tell when your knowledge needs updating?

How often should you refresh IOSH managing safely?

IOSH recommends that people who have completed Managing Safely take a refresher course periodically. Its official guidance recommends refreshing the training every three years to keep health and safety knowledge current.

However, the right time to revisit your training can also depend on your role, workplace and responsibilities. If you manage a team in an environment where risks or procedures change regularly, you may need to review your knowledge more frequently.

Five signs you may need an IOSH refresher

Even if your certificate is relatively recent, there are several reasons to consider updating your knowledge.

1. Your training was several years ago

Health and safety expectations, workplace practices and guidance can change. A refresher helps you revisit essential principles and check that your approach remains relevant.

2. You’ve taken on new responsibilities

Perhaps you’ve been promoted, started managing a larger team or become responsible for additional workplace activities. Revisiting health and safety training can help you feel better prepared for these responsibilities.

3. Your workplace has changed

New equipment, working methods, substances or processes can introduce different hazards. Your knowledge needs to keep pace with changes that affect how risks should be assessed and controlled.

4. You’ve noticed gaps in your knowledge

If you’re uncertain about risk assessments, incident investigations or the hierarchy of risk controls, refresher training provides an opportunity to revisit these areas.

5. You want to strengthen your safety culture

Effective safety management involves more than knowing the rules. It means helping employees understand risks, encouraging them to report concerns and making safety part of everyday decision-making.

What does an IOSH Managing Safely Refresher cover?

The refresher course revisits important health and safety management principles, helping learners reinforce their understanding and apply it to their current responsibilities.

Topics may include identifying hazards, assessing and controlling risks, understanding management responsibilities, investigating incidents and measuring safety performance.

The aim is to reinforce existing knowledge rather than simply repeat the original training. This can help managers recognise potential problems earlier and make more informed decisions about workplace safety.

Keep your health and safety knowledge current

An IOSH Managing Safely refresher is worth considering when your existing training is due for review, your responsibilities change or you need to strengthen your understanding of workplace risks.

By revisiting the essentials, managers can maintain their confidence, support their teams and help create a safer working environment.
