  1. What is the meaning of the letters 'HAZCHEM' in relation to dangerous goods incidents?

    Answer: A UK emergency action code system displayed on HAZCHEM plates to guide emergency services responding to incidents

    HAZCHEM plates are used in the UK and Australia as an additional emergency action code system. The HAZCHEM code tells emergency services what firefighting agent to use, whether protective clothing is needed, and whether evacuation is required.

  2. What class are infectious substances assigned to in ADR?

    Answer: Class 6.2

    Infectious substances (substances containing microorganisms known or reasonably expected to cause infectious disease in humans or animals) are Class 6.2 under ADR. Class 6.1 covers toxic substances. Medical or clinical waste carrying infectious risk is also Class 6.2.

  3. What is the significance of the letter 'X' at the start of a Kemler code?

    Answer: The substance must not come into contact with water

    In the Kemler code, a leading 'X' (e.g. X80) means the substance reacts dangerously with water. Emergency services must not use water to fight a fire involving such substances, as this could cause a violent reaction or release of toxic gas.

  4. Which authority enforces ADR compliance in Great Britain?

    Answer: DVSA (Driver and Vehicle Standards Agency)

    DVSA enforces ADR compliance for road transport in Great Britain. DVSA examiners can check driver certificates, transport documents, vehicle markings, and equipment at the roadside. The HSE and local authorities may also have enforcement roles for storage and workplace aspects.

  5. What does a radioactive (Class 7) transport index (TI) number indicate?

    Answer: The level of radiation dose rate at 1 metre from the package — used to control accumulation limits in vehicles

    The Transport Index (TI) is a number on the label of a radioactive package indicating the maximum radiation dose rate in microsieverts per hour at 1 metre from the surface. TI values are used by carriers to ensure safe accumulation limits are not exceeded.

  6. What is the rule for segregation of dangerous goods from food in the same vehicle?

    Answer: Dangerous goods that could contaminate food (toxic, corrosive, infectious) must be segregated from food shipments and adequate separation maintained

    ADR requires that dangerous goods that could contaminate food (particularly toxic, corrosive, or infectious substances) must not be loaded in the same vehicle as food or animal feed unless adequately separated by a solid partition or sufficient distance.
