Question 1General ADR provisions, scope and structure of the Agreement

Under ADR, which document is carried on board to identify the substances being transported and to link them to the applicable special provisions?

  1. The driver's certificate of professional competence, which lists approved cargo types
  2. The transport document, which must contain the prescribed ADR information for each dangerous good Correct answer.
  3. The vehicle registration certificate, which lists the permitted load classes
  4. The insurance certificate, which states the classes of dangerous goods covered

Explanation

ADR requires a transport document for every consignment of dangerous goods, and it must contain the information prescribed by the Agreement, including the UN number, proper shipping name, class, packing group and tunnel restriction code where applicable. This document is what links the load to the relevant packing and carriage requirements. The other documents listed serve different legal purposes and do not carry the prescribed dangerous goods description.

Question 2General ADR provisions, scope and structure of the Agreement

What is the primary purpose of the ADR Agreement as set out in its scope provisions?

  1. To harmonise the conditions under which dangerous goods may be carried internationally by road Correct answer.
  2. To set maximum permitted axle loads for heavy goods vehicles in international traffic
  3. To standardise driving licence categories recognised between Contracting Parties
  4. To regulate working time and rest periods for drivers on international journeys

Explanation

ADR is an international agreement that harmonises the safety conditions for the international carriage of dangerous goods by road, covering classification, packing, vehicle requirements, documentation and training. Axle loads, licence categories and driving time are governed by other international and national rules. Its purpose is safety harmonisation, not transport market regulation.

Question 3General ADR provisions, scope and structure of the Agreement

Which Annex of ADR contains the provisions on dangerous goods packing, including packing instructions and requirements for packagings, IBCs and large packagings?

  1. Annex B, Part 7
  2. Annex A, Part 4
  3. Annex A, Part 6 Correct answer.
  4. Annex B, Part 9

Explanation

The ADR Annexes are structured in Parts. Part 6 of Annex A sets out the requirements for the construction and testing of packagings, intermediate bulk containers, large packagings and tanks, together with the packing instructions referenced in Part 4. Part 4 addresses the use of packagings rather than their construction requirements. Parts 7 and 9 of Annex B concern loading, unloading and vehicle equipment respectively.

Question 4General ADR provisions, scope and structure of the Agreement

A consignor hands over a load of dangerous goods to a carrier. Under ADR, which party is responsible for classifying the goods and providing the correct transport information?

  1. The driver, because it must check the load before departure
  2. The consignor, because it must identify the goods and provide the required information Correct answer.
  3. The carrier, because it must decide how the vehicle is equipped
  4. The loader, because it physically places the goods on the vehicle

Explanation

ADR assigns the duty of classification and of providing the prescribed information to the consignor, who offers the goods for carriage. The carrier, loader and driver have their own defined duties, such as vehicle suitability, secure loading and pre-departure checks, but they do not replace the consignor's obligation to classify and describe the goods correctly.

Question 5General ADR provisions, scope and structure of the Agreement

Which statement correctly describes the relationship between ADR and the carriage of dangerous goods that is exempted under the small load provisions?

  1. Exempted small loads are entirely outside the scope of ADR and no ADR rules apply to them at all
  2. Exempted small loads must still carry full ADR documentation and orange plates
  3. Exempted small loads are free from most ADR requirements but remain subject to general safety and national rules Correct answer.
  4. Exempted small loads may only be carried by vehicles equipped with orange plates

Explanation

ADR contains provisions for small quantities that exempt certain loads from most of the Agreement's requirements. However, exemption from ADR does not mean the carriage is unregulated: general safety obligations and applicable national traffic rules continue to apply. The other statements wrongly extend or deny the effect of the exemption.

Question 6General ADR provisions, scope and structure of the Agreement

What does the term 'Contracting Party' mean in the context of ADR?

  1. A testing body approved to certify packagings
  2. A state that is party to the ADR Agreement Correct answer.
  3. A company that has signed a commercial contract to carry dangerous goods
  4. A vehicle manufacturer authorised to build ADR vehicles

Explanation

In ADR, a Contracting Party is a state that is party to the Agreement, and the Agreement's rules apply to international carriage between such states. Companies, testing bodies and manufacturers have roles under ADR but are not Contracting Parties. The term is a matter of public international law, not commercial contracting.

Question 7General ADR provisions, scope and structure of the Agreement

A carrier plans an international journey that begins in a Contracting Party and passes through a non-Contracting Party before ending in another Contracting Party. How does ADR address such a journey?

  1. ADR may apply to the whole journey if the states concerned agree to treat it as such under the Agreement's provisions Correct answer.
  2. ADR applies only to the segments within Contracting Parties, and each segment is governed separately
  3. ADR does not apply at all because the journey is not wholly within Contracting Parties
  4. ADR applies only if the non-Contracting Party issues a written waiver

Explanation

ADR contains provisions allowing carriage that is partly performed in non-Contracting Party territory to be treated as carriage under the Agreement where the states involved so agree. The Agreement therefore does not simply stop at the border. The other options misstate the mechanism or deny ADR's reach entirely.

Question 8General ADR provisions, scope and structure of the Agreement

Which Part of ADR Annex A deals with the classification of dangerous goods, including the criteria for assigning classes and packing groups?

  1. Part 1
  2. Part 3
  3. Part 2 Correct answer.
  4. Part 5

Explanation

Part 2 of Annex A contains the classification provisions, including the criteria for the various classes and the assignment of packing groups. Part 3 contains the Dangerous Goods List and the special provisions, Part 5 covers consignment procedures and documentation, and Part 1 contains general provisions. Knowing this structure helps locate the correct rule quickly.

Question 9General ADR provisions, scope and structure of the Agreement

A consignor offers a substance that is not named by name in the Dangerous Goods List. What is the correct ADR approach?

  1. The consignor must refuse carriage because unnamed substances cannot be carried under ADR
  2. The consignor may choose any class that appears suitable and record it on the transport document
  3. The consignor must classify the substance under the relevant generic or 'n.o.s.' entry using the classification criteria Correct answer.
  4. The carrier must assign the class after inspecting the goods at collection

Explanation

ADR classification is criteria-based: a substance not listed by name is assigned to the appropriate generic or not otherwise specified entry according to its hazard properties, following the classification provisions in Part 2. The consignor is responsible for this determination. Neither free choice of class nor automatic refusal is correct.

Question 10General ADR provisions, scope and structure of the Agreement

Which of the following best describes the function of the Dangerous Goods List in ADR?

  1. It sets out the technical construction standards for tank vehicles
  2. It records the Contracting Parties and their national derogations
  3. It lists the names of approved carriers authorised to transport each class
  4. It provides, for each entry, the UN number, name, class, packing group and the specific provisions that apply Correct answer.

Explanation

The Dangerous Goods List in Part 3 is the central reference table: for each entry it gives the UN number, proper shipping name, class, packing group and cross-references to special provisions, packing instructions and other requirements. It is not a list of authorised carriers, a tank construction standard, or a register of derogations.

Question 11General ADR provisions, scope and structure of the Agreement

Under ADR, what is the role of the safety adviser (dangerous goods safety adviser) for an undertaking involved in carriage?

  1. To help the undertaking comply with the rules governing its dangerous goods activities Correct answer.
  2. To act as the competent authority for the undertaking's operations
  3. To drive vehicles carrying high-consequence dangerous goods when required
  4. To issue the ADR certificate of approval for vehicles

Explanation

ADR requires certain undertakings to appoint a safety adviser whose task is to assist in preventing risks inherent in the relevant activities and to help ensure compliance with the applicable rules. The adviser does not drive, does not issue vehicle certificates of approval and does not exercise the powers of a competent authority.

Question 12General ADR provisions, scope and structure of the Agreement

Which Annex B Part contains the requirements for vehicle crews, equipment, operation and documentation during carriage?

  1. Part 9
  2. Part 7
  3. Part 5
  4. Part 8 Correct answer.

Explanation

Part 8 of Annex B sets out the operational requirements for vehicle crews, including training, equipment to be carried, supervision of vehicles and documentation. Part 7 covers loading, unloading and handling, Part 9 covers vehicle construction and approval, and Part 5 of Annex A covers consignment procedures.

Question 13General ADR provisions, scope and structure of the Agreement

A consignment is described in the transport document with the UN number, proper shipping name and class, but the packing group is omitted although one is assigned. What is the correct assessment?

  1. The omission is acceptable because the packing group is only relevant to the packer
  2. The document is complete because the class alone determines the packing requirements
  3. The document is incomplete, because the packing group must be shown where the entry assigns one Correct answer.
  4. The omission is acceptable if the vehicle carries orange plates

Explanation

The prescribed transport document information includes the packing group where the Dangerous Goods List assigns one to the substance. Omitting it makes the description incomplete, since the packing group affects packing, marking and other requirements. Orange plates and internal packer knowledge do not cure a defective consignment description.

Question 14General ADR provisions, scope and structure of the Agreement

Which statement about the ADR provisions for the carriage of dangerous goods in limited quantities is correct?

  1. Limited quantity consignments must meet all the same requirements as full carriage
  2. Limited quantity consignments are subject to reduced requirements compared with fully regulated carriage Correct answer.
  3. Limited quantity consignments are prohibited on international journeys
  4. Limited quantity consignments require a certificate of approval for the vehicle

Explanation

ADR provides that goods packed in limited quantities, meeting the applicable quantity limits and packaging conditions, benefit from reduced requirements for marking, documentation and vehicle equipment. They are not prohibited, and they are not subject to the full set of requirements. A vehicle certificate of approval is not the consequence of using limited quantities.

Question 15General ADR provisions, scope and structure of the Agreement

Which body is responsible for keeping the ADR Agreement and its Annexes up to date, including adopting amendments?

  1. The Working Party on the Transport of Dangerous Goods of the Inland Transport Committee Correct answer.
  2. The United Nations Security Council
  3. The International Maritime Organization
  4. The European Court of Justice

Explanation

Amendments to ADR are prepared and adopted within the framework of the United Nations Economic Commission for Europe, through the Working Party on the Transport of Dangerous Goods, and enter into force for Contracting Parties according to the Agreement's procedures. The Security Council, IMO and the Court of Justice do not perform this function for ADR.

Question 16General ADR provisions, scope and structure of the Agreement

An undertaking carries dangerous goods only in quantities below the thresholds for which a safety adviser is required. What does ADR require regarding the safety adviser?

  1. A safety adviser must still be appointed because all carriers are covered
  2. The driver must perform the safety adviser's duties instead
  3. No safety adviser is required, because the obligation applies only to undertakings exceeding the specified activity thresholds Correct answer.
  4. The competent authority must appoint an adviser for the undertaking

Explanation

The safety adviser obligation applies to undertakings whose dangerous goods activities exceed certain thresholds set out in the ADR provisions; below those thresholds no adviser need be appointed. The duty does not fall automatically on the driver, and competent authorities do not appoint advisers for private undertakings.

Question 17General ADR provisions, scope and structure of the Agreement

Which combination correctly pairs an ADR Annex A Part with its subject matter?

  1. Part 4 – construction and testing of packagings
  2. Part 6 – consignment procedures and documentation
  3. Part 4 – use of packagings, including packing provisions and instructions Correct answer.
  4. Part 2 – vehicle crew and operational requirements

Explanation

Part 4 of Annex A governs the use of packagings, including the packing provisions and the packing instructions that apply to a given entry. Construction and testing are in Part 6, consignment procedures are in Part 5, and crew and operational requirements are in Annex B, Part 8. The other pairings therefore mismatch part and subject.

Question 18General ADR provisions, scope and structure of the Agreement

A consignor argues that because the carrier accepted the goods and loaded them without objection, responsibility for any misdescription has passed to the carrier. How should this be assessed under ADR?

  1. Responsibility passes fully to the carrier once it accepts the goods for carriage
  2. Responsibility passes to the loader because loading confirms the description
  3. The consignor remains responsible for the accuracy of the prescribed information, and other parties retain their own distinct duties Correct answer.
  4. Responsibility is shared equally between consignor and driver in all cases

Explanation

ADR allocates distinct duties to each party rather than transferring them by acceptance. The consignor must provide accurate prescribed information, while the carrier, loader and driver remain responsible for their own obligations such as vehicle suitability, safe loading and pre-journey checks. Acceptance or loading does not extinguish the consignor's duty.

Question 19General ADR provisions, scope and structure of the Agreement

Which statement most accurately reflects how ADR treats national and international carriage within its scope?

  1. ADR applies directly to all domestic carriage within every Contracting Party without any national measure
  2. ADR applies only to carriage by vehicles above a fixed gross vehicle weight
  3. ADR applies only to international carriage, but Contracting Parties commonly extend its requirements to domestic carriage through national law Correct answer.
  4. ADR applies to international carriage and prohibits Contracting Parties from regulating domestic carriage

Explanation

ADR is an international agreement governing international carriage between Contracting Parties. In practice, Contracting Parties typically give effect to its requirements for domestic carriage through national legislation, which is why the same rules are familiar nationally. ADR itself does not automatically regulate all domestic transport, nor does it prohibit national regulation, and it is not defined by a gross vehicle weight threshold.

Question 20General ADR provisions, scope and structure of the Agreement

A consignment meets the conditions for a total exemption from ADR. Which statement best captures the legal position?

  1. The exemption lapses automatically when the vehicle crosses a border
  2. The ADR requirements covered by the exemption do not apply, but other applicable law and general safety duties continue Correct answer.
  3. No ADR requirement whatsoever applies, and the goods lose their dangerous character in law
  4. The exemption applies only if the vehicle displays orange plates

Explanation

Exemptions in ADR remove the application of specified ADR requirements for qualifying carriage; they do not create a legal vacuum. Other applicable law, including national traffic and safety rules, continues to apply, and the goods remain dangerous in nature. Orange plates and border crossings are not conditions attached to the exemption itself.

Question 21Classification of dangerous goods and dangerous goods lists

Under ADR, into which class does a substance with UN number 1203 (petrol/motor spirit) fall?

  1. Class 3, flammable liquids Correct answer.
  2. Class 2, gases
  3. Class 9, miscellaneous dangerous substances
  4. Class 8, corrosive substances

Explanation

UN 1203 is petrol (motor spirit or gasoline), which is a flammable liquid with a flash point well below 23 °C, so it is assigned to Class 3. The UN number is the key that links a substance to its entry in the dangerous goods list, where the class and packing group are fixed.

Question 22Classification of dangerous goods and dangerous goods lists

In the ADR dangerous goods list, what does the packing group (PG) column indicate?

  1. The size of the vehicle allowed to carry the goods
  2. The temperature at which the substance must be stored
  3. The maximum quantity allowed per inner packaging
  4. The degree of danger the substance presents within its class Correct answer.

Explanation

Packing group I, II or III expresses the degree of danger within a class, with I being the greatest danger. It drives which packing instructions and packaging performance levels apply to the substance.

Question 23Classification of dangerous goods and dangerous goods lists

A consignment contains a substance whose ADR entry shows a classification code of 'F1'. What does the 'F' in this code indicate?

  1. The substance is corrosive
  2. The substance is toxic
  3. The substance is infectious
  4. The substance is flammable Correct answer.

Explanation

In ADR classification codes the leading letter indicates the hazard type within the class: F stands for flammable. The digit that follows distinguishes the specific sub-category within that group.

Question 24Classification of dangerous goods and dangerous goods lists

Which document assigns a substance to a UN number and class in the ADR system?

  1. The IMDG Code volume on port operations
  2. The ICAO Technical Instructions for air cargo
  3. The RID regulation for rail transport
  4. The European Agreement concerning the International Carriage of Dangerous Goods by Road, Table A of Chapter 3.2 Correct answer.

Explanation

ADR Table A in Chapter 3.2 is the dangerous goods list that links UN numbers, names, classes, packing groups and special provisions. It is the primary reference for classifying and identifying a consignment under ADR.

Question 25Classification of dangerous goods and dangerous goods lists

A driver is offered a substance labelled with UN 1789, which ADR lists as hydrochloric acid. Which class does this entry belong to?

  1. Class 6.1, toxic substances
  2. Class 5.1, oxidizing substances
  3. Class 3, flammable liquids
  4. Class 8, corrosive substances Correct answer.

Explanation

Hydrochloric acid (UN 1789) is a corrosive substance assigned to Class 8. It attacks skin and metals, which is the defining hazard of that class.

Question 26Classification of dangerous goods and dangerous goods lists

What is the purpose of a special provision listed in column 6 of ADR Table A?

  1. It replaces the packing group with a fixed quantity
  2. It defines the tunnel category for the route
  3. It changes the UN number of the substance
  4. It adds or modifies requirements that apply to that specific entry Correct answer.

Explanation

Special provisions are numbered codes in column 6 that add, relax or modify the standard requirements for a particular entry. They must be read together with the general rules in the relevant chapters.

Question 27Classification of dangerous goods and dangerous goods lists

A substance is listed in ADR with the proper shipping name 'ACETONE'. Which class and packing group should the consignor expect for this entry?

  1. Class 8, packing group I
  2. Class 6.1, packing group III
  3. Class 2, packing group II
  4. Class 3, packing group II Correct answer.

Explanation

Acetone is a flammable liquid with a flash point of about -20 °C, placing it in Class 3. Its ADR entry assigns packing group II, reflecting a moderate degree of danger within that class.

Question 28Classification of dangerous goods and dangerous goods lists

A consignor has a solution that is not specifically named in ADR Table A. What is the correct approach to classification?

  1. Classify it as Class 9 in every case
  2. Refuse transport because unnamed substances cannot be carried
  3. Use the appropriate generic or 'n.o.s.' entry that matches the hazard characteristics Correct answer.
  4. Assign the nearest UN number of a similar named substance without further checks

Explanation

Substances not specifically listed are assigned to a generic or 'not otherwise specified' (n.o.s.) entry whose name reflects the chemical and hazard properties. The choice must be based on the actual hazard characteristics determined by testing or established data.

Question 29Classification of dangerous goods and dangerous goods lists

What does the column 'Limited and excepted quantities' in ADR Table A provide for an entry?

  1. The minimum distance between vehicles in a convoy
  2. The maximum speed at which the vehicle may travel
  3. The number of crew required for the journey
  4. The maximum quantity per inner and outer packaging for limited-quantity carriage Correct answer.

Explanation

The limited and excepted quantity columns give the maximum quantities per inner and outer packaging that allow the consignment to benefit from the simplified rules of Chapter 3.4 or 3.5. These limits are specific to each entry.

Question 30Classification of dangerous goods and dangerous goods lists

A substance has a classification code beginning with 'T' in ADR. Which hazard does the leading letter indicate?

  1. Toxic Correct answer.
  2. Radioactive
  3. Flammable
  4. Oxidizing

Explanation

In ADR classification codes, T indicates a toxic substance within Class 6.1. The following digits or letters refine the sub-category, for example whether it is a pesticide or another toxic group.

Question 31Classification of dangerous goods and dangerous goods lists

A consignment of a Class 3 substance is being prepared. Which factor most directly determines whether packing group I, II or III applies?

  1. The colour of the liquid
  2. The country of destination
  3. The flash point and initial boiling point of the substance Correct answer.
  4. The size of the transport vehicle

Explanation

For Class 3, packing group assignment depends on flash point and initial boiling point thresholds set out in the classification criteria. A low flash point and low boiling point indicate the greatest danger and packing group I.

Question 32Classification of dangerous goods and dangerous goods lists

What is the role of the proper shipping name in ADR Table A?

  1. It is a commercial brand name chosen by the consignor
  2. It is an optional description for marketing purposes
  3. It is the name of the manufacturer of the substance
  4. It is the official name that must be used in transport documents and markings Correct answer.

Explanation

The proper shipping name is the official designation shown in the dangerous goods list and must appear on documentation and package markings. Using it ensures emergency responders and authorities identify the hazard correctly.

Question 33Classification of dangerous goods and dangerous goods lists

A substance carries UN 1263, PAINT, and the consignor wants to know its transport category for tunnel restrictions. Where should this be found?

  1. In the packing instruction referenced in column 8
  2. In the special provision referenced in column 6
  3. In column 3 of Table A, which lists the class
  4. In column 15 of Table A, which gives the transport category Correct answer.

Explanation

The transport category used for tunnel restrictions is given in column 15 of ADR Table A. It determines which tunnel category codes the vehicle must avoid.

Question 34Classification of dangerous goods and dangerous goods lists

A package contains a substance with UN 2814, INFECTIOUS SUBSTANCE, AFFECTING HUMANS. Which class does this belong to?

  1. Class 8
  2. Class 6.1
  3. Class 9
  4. Class 6.2 Correct answer.

Explanation

UN 2814 is an infectious substance affecting humans, which is assigned to Class 6.2. Class 6.2 covers infectious substances capable of causing disease in humans or animals.

Question 35Classification of dangerous goods and dangerous goods lists

A consignor is checking whether a new chemical must be classified under ADR. Which sequence best reflects the correct classification approach?

  1. Choose the lowest UN number in the list and use it
  2. Ask the driver to decide the class at loading
  3. Check flash point only, then assign a class
  4. Determine the hazard properties, match them to the class criteria, then find the specific or generic entry in Table A Correct answer.

Explanation

Classification starts with establishing the physical, chemical and toxicological properties of the substance. Those properties are then tested against the class criteria in Part 2, and finally the appropriate entry is located in Table A.

Question 36Classification of dangerous goods and dangerous goods lists

A substance appears in ADR Table A with the entry 'UN 3082, ENVIRONMENTALLY HAZARDOUS SUBSTANCE, LIQUID, N.O.S.'. Which class does this entry belong to?

  1. Class 6.1
  2. Class 3
  3. Class 8
  4. Class 9 Correct answer.

Explanation

UN 3082 is the generic entry for environmentally hazardous substances, liquid, n.o.s., which is placed in Class 9. Class 9 covers substances that present a hazard not covered by the other classes, including environmental hazards.

Question 37Classification of dangerous goods and dangerous goods lists

Two substances share similar chemical properties but one has a much lower flash point. How does this difference affect their ADR classification within Class 3?

  1. Packing group is unaffected by flash point
  2. The substance with the lower flash point is moved to Class 8
  3. Both will always be packing group III
  4. The substance with the lower flash point may fall into a more severe packing group Correct answer.

Explanation

Within Class 3, packing group assignment depends on flash point and initial boiling point thresholds. A lower flash point generally indicates a greater fire hazard and can place the substance in a more severe packing group such as I or II.

Question 38Classification of dangerous goods and dangerous goods lists

A consignor finds two possible entries for a solvent mixture: a specific named entry and a generic n.o.s. entry. Which choice is correct under ADR?

  1. Always use the generic n.o.s. entry because it is simpler
  2. Use whichever entry has the lower UN number
  3. Use both entries on the same document
  4. Use the specific named entry when the substance meets that entry's definition Correct answer.

Explanation

ADR requires that a specifically named entry be used when the substance corresponds to it, because a generic n.o.s. entry is only for substances not covered by a specific name. Selecting the specific entry ensures the correct packing and hazard provisions apply.

Question 39Classification of dangerous goods and dangerous goods lists

A substance's ADR entry includes a classification code of 'C4' and appears in Class 8. What does this tell you about the substance?

  1. It is a toxic gas
  2. It is a flammable solid in Class 4
  3. It is an organic peroxide
  4. It is a corrosive substance in a specific sub-category of Class 8 Correct answer.

Explanation

The leading letter C shows the substance belongs to the corrosive group within Class 8, and the digit identifies the particular sub-category. The classification code refines the hazard description but does not change the class.

Question 40Classification of dangerous goods and dangerous goods lists

A consignment is described only by a trade name on the transport document. Why is this insufficient under ADR?

  1. Trade names are only allowed for Class 9 goods
  2. ADR requires the proper shipping name together with the UN number and other prescribed particulars Correct answer.
  3. Trade names are too long for the document
  4. The document must instead show the manufacturer's address

Explanation

ADR prescribes the information that must appear on the transport document, including the UN number and the proper shipping name in the correct order. A trade name alone does not identify the hazard and cannot replace the required particulars.

Question 41Packaging, IBCs, tanks, and package marking/labelling

Under ADR, which mark is required on the outside of a combination packaging that contains dangerous goods in packagings intended for retail sale?

  1. The name and address of the consignee
  2. The UN packaging symbol followed by the packaging code
  3. The proper shipping name of the goods in full
  4. The UN number of the goods preceded by the letters UN Correct answer.

Explanation

For combination packagings containing dangerous goods for retail sale, ADR permits the UN number to be shown in place of the UN packaging symbol, but the number must be preceded by the letters "UN". The mark is placed on the outer packaging, not on the inner receptacles. This lets handlers identify the goods without opening the retail packaging.

Question 42Packaging, IBCs, tanks, and package marking/labelling

A new steel drum is marked with the code "1A1/Y1.4/150/24/N/S/SP123". What does the figure "150" represent in this code?

  1. The hydrostatic test pressure in kPa Correct answer.
  2. The test pressure in kPa for liquids
  3. The maximum gross mass in kilograms
  4. The stacking test load in kilograms

Explanation

In the UN packaging code, the figure after the specific gravity or mass value is the hydrostatic test pressure in kPa for packagings intended for liquids. The value 150 therefore means the drum was tested at 150 kPa. It is a pressure figure, not a mass figure.

Question 43Packaging, IBCs, tanks, and package marking/labelling

Which body is responsible for issuing the approval certificate for a flexible IBC used for dangerous goods?

  1. The manufacturer's in-house testing laboratory
  2. The competent authority of the country of manufacture Correct answer.
  3. The carrier operating the transport unit
  4. The consignor's national competent authority only

Explanation

Flexible IBCs must be approved by the competent authority of the country in which they are manufactured, and the approval covers the design type. The manufacturer's own laboratory may perform tests, but it cannot issue the approval. Carriers and consignors have no approval role.

Question 44Packaging, IBCs, tanks, and package marking/labelling

On an IBC, where must the UN packaging symbol and code be displayed?

  1. On the inner liner only
  2. Inside the discharge valve housing
  3. On a durable plate or label affixed in a readily visible place Correct answer.
  4. Only on the accompanying transport document

Explanation

ADR requires IBCs to bear the UN packaging symbol and code on a durable plate or label that is readily visible and legible. The mark must survive the service life of the IBC. It is not carried only on paperwork or hidden inside components.

Question 45Packaging, IBCs, tanks, and package marking/labelling

A portable tank is offered for transport. Which marking must appear on the tank itself in addition to the UN number and proper shipping name?

  1. The date of the last consignee delivery
  2. The driver's licence category
  3. The owner's telephone number
  4. The tare mass and the maximum permissible gross mass Correct answer.

Explanation

Portable tanks must display the tare mass and the maximum permissible gross mass, together with other required data such as the test pressure and capacity. These figures let inspectors confirm filling limits and structural limits. Owner contact details and delivery records are not part of the required tank marking.

Question 46Packaging, IBCs, tanks, and package marking/labelling

An empty, uncleaned tank vehicle that last carried a toxic substance is being moved to a cleaning station. What does ADR require regarding its placarding?

  1. Placards must remain displayed as for the last load carried Correct answer.
  2. Only the orange plate at the rear is needed
  3. A single plain white placard is sufficient
  4. Placards must be removed because the tank is empty

Explanation

Empty uncleaned tanks and tank vehicles retain the placards and orange plates appropriate to the substance last carried, because residue hazards remain. Cleaning or purging is what allows the placards to be removed. The quantity remaining is irrelevant to this rule.

Question 47Packaging, IBCs, tanks, and package marking/labelling

Which of the following correctly describes the purpose of the UN packaging symbol in a packaging mark?

  1. It confirms that the consignor holds insurance
  2. It certifies that the contents are non-hazardous
  3. It indicates that the packaging conforms to a tested and approved design type Correct answer.
  4. It shows the country where the goods were produced

Explanation

The UN packaging symbol shows that the packaging has met the design-type tests for its code and thus conforms to an approved design. It says nothing about the goods themselves or about commercial arrangements. Inspectors use it to link the physical packaging to its tested specification.

Question 48Packaging, IBCs, tanks, and package marking/labelling

A consignor fills a 1A1 drum marked with a specific gravity of 1.4 with a liquid of specific gravity 1.6. What is the correct assessment?

  1. This is not permitted because the liquid exceeds the marked specific gravity Correct answer.
  2. This is permitted because the drum is metal
  3. This is permitted if the journey is domestic only
  4. This is permitted if the drum is filled to 98% capacity

Explanation

The marked specific gravity is the maximum density the packaging was tested and approved for. Filling with a denser liquid exceeds that limit and is not permitted, regardless of the material or journey type. The consignor must select packaging with an adequate marked value.

Question 49Packaging, IBCs, tanks, and package marking/labelling

What information must appear on the approval certificate for a rigid IBC design type?

  1. The insurance policy number of the manufacturer
  2. The consignee's delivery address
  3. The marks prescribed for the IBC and the design type designation Correct answer.
  4. The name of the driver assigned to the route

The approval certificate for an IBC design type must show the marks prescribed for IBCs and the design type designation, along with other particulars such as the competent authority and testing details. It is a design approval document, not a shipment document. Driver and consignee details belong to the individual journey.

Question 50Packaging, IBCs, tanks, and package marking/labelling

Which statement about the marking of salvage packagings is correct?

  1. They are exempt from all marking
  2. They carry only the consignor's name
  3. They carry the word SALVAGE in addition to the normal packaging marks Correct answer.
  4. They are marked with the word RECOVERED

Explanation

Salvage packagings must bear the word "SALVAGE" together with the other required packaging marks. This alerts handlers that the packaging encloses damaged, defective or leaking dangerous goods. They are not exempt from marking, and the term RECOVERED is not used.
