NEBOSH vs OZO: Which HSE Qualification Should You Look For?

If you're looking for an HSE consultant or in-house safety officer in the Czech Republic, you'll likely encounter two types of qualifications: the Czech OZO (Odborně způsobilá osoba v prevenci rizik) and the internationally recognised NEBOSH certificate. Understanding the difference helps you make an informed choice.

What is OZO?

OZO stands for Odborně způsobilá osoba v prevenci rizik — loosely translated as "professionally qualified person in risk prevention." It's a Czech national qualification regulated by the State Labour Inspection Office (SÚIP).

To obtain OZO status, a candidate must:

• Hold a relevant educational qualification
• Complete an approved training course
• Pass a written and oral examination administered by an accredited institution
• Maintain continuing professional development

OZO is the legally required qualification for the person responsible for ensuring compliance with workplace safety legislation in Czech companies above a certain size. Without an OZO-certified person, your organisation is non-compliant.

What is NEBOSH?

NEBOSH (National Examination Board in Occupational Safety and Health) is a UK-based awarding body whose qualifications are recognised globally — in over 170 countries. The most widely held is the NEBOSH International General Certificate in Occupational Health and Safety (IGC).

NEBOSH programmes cover:

• Management of health and safety
• Risk assessment and hazard identification
• Workplace and work equipment safety
• Electrical, fire, and chemical hazards
• Environmental considerations

NEBOSH doesn't confer legal status in the Czech Republic — that's what OZO does. But it provides a depth of practical, internationally benchmarked HSE knowledge that complements Czech regulatory training.

Which one matters more?

For Czech legal compliance: OZO is essential. Any organisation required to have an in-house safety officer or retain an external HSE professional must ensure that person holds a valid OZO qualification.

For practical expertise and international standards: NEBOSH adds significant value. The NEBOSH curriculum is rigorous and directly practical in ways that many national certification courses aren't. A consultant holding both qualifications brings legal standing and international best-practice thinking.

At Solid Safety, we hold both OZO and NEBOSH qualifications — ensuring our clients receive advice that's legally grounded in Czech requirements and benchmarked against the best international standards.

Bottom line

When selecting an HSE consultant or safety officer, look for:

• OZO — confirms they can legally fulfil the role in Czech companies
• NEBOSH or equivalent — signals broader, more rigorous training
• Relevant sector experience — qualifications alone don't guarantee practical value
