LGV Dangerous Goods (ADR Basics) 2

Question 1

What placards (diamond-shaped labels) must be displayed on a vehicle carrying dangerous goods?

Accepted Answer

Large diamond hazard warning placards (250mm minimum) on both sides and rear of the vehicle, and any required orange Kemler plates

Answer

Vehicles carrying dangerous goods above threshold quantities must display large diamond placards (minimum 250mm) on the front, both sides, and rear of the vehicle. The placards must correspond to the hazard class(es) of the goods carried.

Question 2

What is the 'limited quantity' (LQ) exemption in ADR?

Accepted Answer

Small quantities of dangerous goods packed in limited sizes are exempt from many ADR requirements but still require basic hazard marking

Answer

The Limited Quantities exemption allows small amounts of certain dangerous goods (packed in small containers of specific maximum sizes) to be transported without full ADR compliance. LQ shipments must still show a limited quantity mark (diamond with 'LQ') on packages.

Question 3

What should an ADR driver do in the event of a fire involving the vehicle or load?

Accepted Answer

Evacuate to a safe distance, call emergency services, and do not attempt to fight a fire involving the dangerous goods themselves

Answer

In a fire involving dangerous goods, the driver should evacuate to a safe distance (at least 300 metres for most substances), keep people away, call emergency services and give them the transport document and written instructions, and not attempt to fight the fire if it involves the dangerous substance.

Question 4

What does the UN number 1203 on an orange Kemler plate indicate?

Accepted Answer

Petrol (gasoline/motor fuel)

Answer

UN 1203 is the UN number for petrol (gasoline/motor fuel). This is one of the most common UN numbers seen on tankers. Understanding common UN numbers helps drivers and emergency services identify substances quickly.

Question 5

What is a 'packing group' in ADR?

Accepted Answer

A classification (I, II, or III) indicating the danger level of the goods — Group I is most dangerous

Answer

Packing groups (I, II, III) classify the degree of danger within a class. Group I substances are highly dangerous, Group II are medium danger, and Group III are low danger. The packing group determines the packaging standards required.
