What Is a Dangerous Goods Safety Advisor?
Since 1 January 2000, any company whose activities involve the carriage, packing, loading, filling or unloading of dangerous goods has been legally required to appoint a Dangerous Goods Safety Advisor (DGSA). The DGSA is the competent person who keeps a business compliant and safe every day it moves hazardous goods.
The DGSA can be one of your own employees or an external consultant. Either way, they must hold a Vocational Training Certificate (VTC), gained by passing the official examinations administered by Qualifications Scotland.
The Qualification: Three Papers
To qualify, a candidate must pass examinations in:
- Core — the regulatory framework, DGSA duties, classification, documentation and general provisions.
- All Classes — the specific provisions for every one of the nine UN hazard classes.
- A Transport Mode paper — Road, Rail or Inland Waterway.
All three papers must be passed within a 12-month period. As the overwhelming majority of dangerous goods travel by road, that is the mode we concentrate on. At a typical quarterly sitting of around 200 UK candidates, fewer than ten sit Rail or Inland Waterway, making publishing a schedule of courses commercially unviable. We arrange training for those modes on request, subject to instructor availability.
Does Your Business Need a DGSA?
If your operation consigns, packs, loads, fills, carries or unloads dangerous goods by road, rail or inland waterway, you almost certainly need access to a qualified DGSA — whether an employee or an appointed consultant.
Who must appoint one
- Consignors sending dangerous goods
- Carriers & hauliers transporting them
- Packers, loaders, fillers & unloaders
- Freight forwarders & 3PL warehouses
- Fuel, chemical & waste operators
- Storage sites within the transport chain
The 2023 consignor change
Companies acting only as consignors were historically exempt. Amendments made in 2019 to the Carriage of Dangerous Goods Regulations (ADR/RID and the UK CDG & TPE Regulations) changed that: from 1 January 2023, consignor-only businesses must also appoint a DGSA. If you package or send hazardous goods and haven’t reviewed your position, now is the time.
When you may be exempt
- Only ever handling limited or excepted quantities
- Staying below the “small load” thresholds in ADR 1.1.3.6
- Only occasional movements, e.g. breakdown recovery
- Emergency, military or police carriage
Even where exempt, many firms still appoint a DGSA to satisfy customer audits and insurers. If in doubt, ask us for a free, no-obligation assessment.
What a DGSA actually does
- Monitors day-to-day compliance with the dangerous goods regulations
- Investigates incidents, near-misses and infringements, recording corrective action
- Prepares the mandatory annual dangerous goods report for senior management
- Advises on packaging, labelling, documentation, vehicles and subcontractors
- Checks staff training records and recommends refresher programmes
- Reviews emergency procedures and transport security plans

The Nine UN Hazard Classes You’ll Master
The “All Classes” paper covers every one of the nine classes below.









How the DGSA Exam Works
The examinations are open-book and sat on the same day. You take the permitted reference materials into the exam room with you — this is not a memory test. It rewards candidates who know how to find and apply the right information under time pressure.
The three papers & how long they take
- Core — 1 hour 15 minutes. Short responses to individual questions.
- All Classes — 1 hour 45 minutes. A mix of short responses and “linked scenario” questions.
- Road (Mode) paper — 1 hour 45 minutes. A case study (you choose which) plus compulsory short-response questions.
You must pass all three within a 12-month period to qualify.
What you can take into the exam
For the Road examinations you’re permitted the current editions of:
- ADR 2025 Volumes 1 & 2
- The Carriage of Dangerous Goods & Use of Transportable Pressure Equipment Regulations
- Carriage of Dangerous Goods: Approved Derogations & Transitional Provisions
- The Dangerous Goods Emergency Action Code (EAC) List, 2025 edition
Inland Waterway candidates require ADN; Rail candidates require RID. Editions must always be the current ones — previous editions are not permitted.
Are electronic versions or devices allowed?
No. The use of all electronic equipment, including CD-ROMs, tablets and phones, is not allowed. Your reference materials must be the printed, current editions.
When do I qualify, and how long does it last?
Your certificate runs from the date of the last paper passed and lasts five years. You must pass all three papers within a rolling 12-month window. Before expiry, you re-qualify by re-examination.
Why Smaller Groups Get Better Results
We cap our DGSA courses at a maximum of 12 candidates. It’s a deliberate choice: the DGSA is a demanding qualification, and the single biggest factor in passing is how much focused instructor time each person gets. A smaller room means more of it.
More instructor time each
With a capped group, the tutor can work through the papers with every candidate individually — not just the confident few — and spot where you’re going wrong before exam day.
Every question answered
Dangerous goods throws up endless “but what about…” scenarios. In a small group there’s time to answer them in the room, using real examples relevant to your own operation.
Pace tuned to the group
Rather than racing a large cohort through fixed slides, we can slow down on the tricky areas — classification, segregation, documentation — and move faster where the group is comfortable.
Condensed learning, delivered to a small group by an experienced instructor, is how we keep our first-time pass rates high — and why so many candidates and employers come back to us.
