Read the first 6 Dangerous Goods (ADR Basics) flashcards as text

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

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

    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.

  2. What is a 'tunnel restriction code' in ADR?

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

    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.

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

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

    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.

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

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

    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.

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

    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

    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.

  6. What is the 'excepted quantity' (EQ) concept in ADR?

    Answer: Very small quantities of certain dangerous goods exempt from most ADR requirements — even smaller than limited quantities

    Excepted Quantities allow tiny amounts of certain dangerous goods (typically milligrams to a few millilitres per package) to be transported with minimal ADR requirements. They are indicated by a diamond mark with 'E' followed by a number on the package.
