What Makes a ‘Competent Person’ in Manufacturing? Legal Duties Explained

In our consultations with businesses, we’ve witnessed countless manufacturing managers grapple with a fundamental question: "Am I legally competent to manage safety in my workplace?" It's a question that keeps conscientious leaders awake at night, and rightly so. With manufacturing recording 11 fatalities in 2024/25, understanding your legal position as a 'competent person' is a vital step in making sure you’re properly equipped.

Let me share what I've learned about navigating this critical requirement, particularly for those of you leading teams on busy production floors where the stakes are highest.

What Is a Competent Person Under UK Safety Law? 

The legal definition sounds deceptively simple, but there's crucial nuance that many miss. Under Regulation 7(5) of the Management of Health and Safety at Work Regulations 1999, a person is regarded as competent where they have "sufficient training and experience or knowledge and other qualities to enable them properly to assist in undertaking the measures referred to".

Notice the word "or" – not "and". This flexibility is intentional, recognising that competence can come from different sources. I've seen brilliant safety leaders who started as shop floor operators, building their competence through years of hands-on experience combined with targeted training.

The key components of competence include:

• Practical understanding of your specific workplace hazards
• Knowledge of relevant health and safety laws and best practices
• Skills to identify risks and implement control measures
• Experience applying safety principles in real-world situations
• Authority and confidence to challenge unsafe practices

What surprises many manufacturing managers is that there's no statutory requirement to be a technically qualified H&S professional. However, in my experience, combining practical knowledge with recognised training creates the strongest foundation for true competence.

Why Manufacturing Managers Must Meet This Standard 

Manufacturing presents unique challenges that make competent safety leadership non-negotiable. The combination of heavy machinery, chemical processes, repetitive tasks and production pressures creates a complex risk landscape.

Latest HSE data shows that manufacturing has statistically significantly higher rates of self-reported work-related ill health than the average across all industries. This isn't just about catastrophic incidents – it's the cumulative effect of musculoskeletal disorders, respiratory conditions, and stress-related illness that truly impacts our workforce.

From my consultancy work across dozens of manufacturing sites, I've identified three critical reasons why managers must prioritise their competence:

1. Dynamic risk environment – Manufacturing processes change rapidly with new products, materials and technologies
2. Diverse workforce – Managing contractors, temporary workers and multi-generational teams requires sophisticated safety leadership
3. Regulatory scrutiny – Manufacturing faces intense oversight, particularly in sectors like pharmaceuticals, food production and automotive

Consider this scenario I encountered recently: A production manager faced with introducing collaborative robots (cobots) to their assembly line. Without competent safety management, this innovation could have exposed workers to new crushing and impact risks. Instead, their IOSH-trained management team conducted thorough risk assessments, implemented appropriate safeguarding, and achieved a 30% productivity increase with zero incidents.

Legal Framework | MHSWR 1999 and HSWA 1974 

Understanding the legal architecture is crucial for manufacturing leaders. Regulation 7(1) of MHSWR states that "Every employer shall... appoint one or more competent persons to assist him in undertaking the measures he needs to take to comply with the requirements and prohibitions imposed upon him".

This sits within the broader framework of the Health and Safety at Work Act 1974, which establishes general duties of care. Together, they create a comprehensive legal structure that manufacturing managers must navigate:

Your Legal Obligations as a Manager

Importantly, Regulation 7(8) states that where there's a competent person in the employer's employment, they should be appointed in preference to an external adviser. This clearly signals the law's preference for developing internal competence – a particularly relevant point for manufacturing organisations with complex, site-specific processes.

The enforcement landscape has also shifted significantly. The HSE can prosecute even if no harm has occurred, simply based on the potential risk that may exist within an organisation's undertakings. I've seen companies face five-figure fines for lacking demonstrable competent person arrangements, even without any incidents occurring.

How IOSH Managing Safely Equips You to Be Legally Competent 

This is where structured training becomes invaluable. The IOSH Managing Safely qualification has become the gold standard for developing competent managers in manufacturing, and for good reason.

Having delivered this training to hundreds of manufacturing professionals, I can attest to its transformative impact. The course addresses the exact competencies required under Regulation 7, but crucially, it does so in a practical, manufacturing-relevant context.

In manufacturing, where a single incident can halt production lines and damage customer relationships, this return on investment is compelling.

FAQs About Competency and Compliance

Q: Can I be personally prosecuted if I'm not competent? A: Yes. Under Section 37 of HSWA, if a company breach is attributed to your neglect as a manager, you face personal criminal liability. I've seen manufacturing directors receive suspended prison sentences – this isn't theoretical risk.

Q: Do I need NEBOSH rather than IOSH for manufacturing? A: IOSH Managing Safely is designed for managers and supervisors who aren't safety experts but need to manage risks effectively, while NEBOSH is more in-depth and suited for full-time safety professionals. For most manufacturing managers, IOSH provides the ideal balance.

Q: How do I know if our current competent person arrangements are adequate? A: Consider these indicators:

• Can they explain the hierarchy of controls specific to your processes?
• Do they understand your unique hazards and applicable regulations?
• Are they confident challenging senior management on safety issues?
• Do they have allocated time and resources for their safety duties?

Q: What if we use external safety consultants? A: While valuable for specialist input, remember that the legal duty to safeguard safety and health lies with the employer and cannot be passed to an outside consultant. You need internal competence to manage day-to-day safety effectively.

Q: How often should competence be reviewed? A: While IOSH certificates don't expire, refresher training every three years is recommended to stay current with changing legislation and best practices. In manufacturing, where processes evolve rapidly, annual competence reviews are advisable.

The path to becoming a truly competent person in manufacturing isn't just about compliance, it's about professional pride in creating workplaces where everyone goes home safely.
