DGSA Exam (UK Dangerous Goods Safety Adviser)

The dangerous goods safety adviser (DGSA) exams qualify you to act as a business's DGSA under ADR 1.8.3 and CDG2009. To qualify you pass three written exams: the Core module, All Classes, and one of Road, Rail or Inland Waterways, and you pass them again every 5 years to stay qualified. The exams are taken in person at venues in England, Scotland and Northern Ireland, administered by Qualifications Scotland and booked on GOV.UK. They are open book: you may take printed copies of ADR (or RID or ADN), CDG2009, the emergency action code list and the approved derogations. Core is 1 hour 15 minutes; All Classes and Road are each 1 hour 45 minutes.
