LGV Dangerous Goods (ADR Basics) 4

Question 1

What personal protective equipment (PPE) must be carried in an ADR vehicle's emergency equipment kit?

Accepted Answer

Warning vest, eye protection (goggles), suitable gloves, and in some cases a breathing protection device

Answer

ADR requires certain PPE to be carried: a warning (high-visibility) vest, eye protection, appropriate gloves, and additional items depending on the substance (such as a breathing protection device for certain classes). The written instructions specify required PPE.

Question 2

What is a 'tunnel restriction code' in ADR?

Accepted Answer

A code (A-E) that restricts which road tunnels certain dangerous goods may pass through

Answer

ADR tunnel restriction codes (A through E) specify restrictions on passing through tunnels with certain dangerous goods. Code E is the most restrictive. Each dangerous substance is assigned a code, and tunnels are categorised. Drivers must check both the substance code and the tunnel category.

Question 3

What is the purpose of the UN Recommendations on the Transport of Dangerous Goods?

Accepted Answer

To provide the foundation model for international dangerous goods regulations including ADR, IMDG, and IATA DGR

Answer

The UN Recommendations on the Transport of Dangerous Goods ('Orange Book') forms the basis for all international modal dangerous goods regulations including ADR (road), IMDG (sea), RID (rail), and IATA DGR (air). It ensures consistency in classification, labelling, and packaging.

Question 4

What does 'Class 8 — Corrosives' mean in ADR terms?

Accepted Answer

Substances that can destroy living tissue and damage metals — including acids and alkalis

Answer

ADR Class 8 covers corrosive substances that can cause full-thickness destruction of skin tissue and/or are significantly corrosive to metals. This includes strong acids (sulphuric, hydrochloric) and strong alkalis (sodium hydroxide). Special packaging and handling precautions apply.

Question 5

What action should an ADR driver take if a dangerous goods container is visibly damaged and leaking?

Accepted Answer

Stop safely, move to a safe distance, call emergency services, give them the transport document and written instructions, and do not attempt to handle the leaking substance

Answer

A leaking dangerous goods container is a serious incident. The driver must stop safely, evacuate to a safe distance, call emergency services (999), provide them with the transport document and written instructions, and not attempt to handle or contain the substance without appropriate PPE and training.
