Unit A: Managing Health and Safety.

Unit B: Hazardous Substances/Agents

Unit DNI: Application of health and safety in the workplace

  • Unit DNI: This unit involves a workplace-based assessment that tests the practical application of knowledge gained in units A-C.

When combined with further professional development, the NEBOSH Diploma meets the standards required to achieve Chartered Safety Practitioner (CMIOSH) status. 

On completion of the NEBOSH International Diploma, you will be entitled to use “DipNEBOSH” after your name and apply for Graduate Membership with the Institution of Occupational Safety and Health (GradIOSH). It also allows full membership to the International Institute of Risk and Safety Management (IIRSM).
