RTO Hazardous Goods Test study plan

Define the nine hazard classes and, within each, the division or category structure, writing your own one-line definition per class without looking at notes.

Assign the correct class and division to 20 described substances (for example a flammable liquid with a flash point of 23 degrees C, or a corrosive with pH below 2) and justify each choice in a single sentence.

Explain how packing group is determined for classes 3, 6 and 8, and apply the flash point, boiling point and toxicity criteria to five worked examples.

Distinguish primary from subsidiary hazard and identify the subsidiary risk for eight substances that carry more than one hazard.

List the hazard classes that are prohibited from transport in your operating context and state the reason for each prohibition.

Map each hazard class to the UN packing instruction group and packaging performance level it typically requires, using a table you build yourself.

Select an appropriate UN packaging code (for example 3H1, 1A2, 4G) for five given substances and explain what each element of the code means.

Describe the periodic inspection, marking and retest obligations for packaging and intermediate bulk containers, and state the intervals in years.

Identify five common packaging defects (damaged closures, missing UN mark, incompatible liner, overfilled package, degraded gasket) and state the rejection decision for each.

Explain the rules for mixed packing inside one outer package and give three combinations that are permitted and three that are not.

Draw from memory a correct hazard label for four different classes, including the pictogram, class number and text elements required.

Explain when a placard is required on a vehicle versus when a label alone suffices, and describe the placarding thresholds that apply.

Write out the required entries of a dangerous goods transport document for a two-substance consignment, including UN number, proper shipping name, class, packing group and quantity.

Identify five documentation errors (wrong UN number, missing packing group, inconsistent quantity, absent emergency contact, undeclared subsidiary risk) and correct each.

State the retention period and who must keep copies of the transport document and related records.

Apply the segregation table to eight pairs of substances and state whether each pair may be loaded together, must be separated, or is prohibited.

Describe the correct loading sequence and securing method for a mixed load of cylinders and packaged flammable liquids, including bracing and restraint.

Explain the rules on loading dangerous goods with foodstuffs, animals and passengers, and give the exception conditions where any exist.

List the checks a driver must complete before, during and after loading and unloading, and convert them into a pre-trip checklist.

Identify five stowage faults visible in a described load (unsecured drum, incompatible neighbour, blocked access to fire equipment, damaged package, missing segregation distance) and state the corrective action.

List the fire extinguisher types and minimum sizes required on a dangerous goods vehicle and match each to the classes of fire it must handle.

Explain the correct response to a tyre fire, an engine fire and a cargo fire, including when to attack and when to withdraw.

Describe the purpose and contents of the vehicle emergency information kit and state where it must be stowed.

Explain the role of the emergency information sheet or instructions in transit and what a driver must do in the first five minutes of an incident.

Identify the vehicle equipment required for a flammable liquid load versus an oxidising load, and note the differences.

Describe the checks that must be made on fire equipment and when defective equipment must be replaced before departure.

State the licence category, endorsements and medical fitness requirements that apply to a driver carrying dangerous goods, and explain how fitness-to-drive is assessed.

Describe the training syllabus areas a dangerous goods driver must cover and the intervals at which refresher training is required.

Explain the employer's obligations for recordkeeping of training, medical checks and licence verification.

Outline the incident reporting chain, including who is notified, what information is required and the time limits for notification.

Describe the immediate actions and containment steps for a small spill of a corrosive and a flammable liquid, including personal protective equipment and waste handling.

State the records that must be kept after an incident and the retention periods that apply.

Explain the tunnel category restrictions that apply to dangerous goods and match five loads to the tunnels they may not enter.

Describe the route restrictions and urban transit rules that commonly apply to dangerous goods vehicles, including time windows and designated routes.

State the parking and supervision rules for a loaded dangerous goods vehicle, including when attended supervision is required.

Plan a route for a described consignment that avoids a restricted tunnel and a restricted urban zone, and justify each diversion.

Identify the signage and marking requirements that apply when a vehicle is parked or stopped with dangerous goods on board.

Complete two full-length timed practice papers under exam conditions and record the score per domain.

Re-study only the two weakest domains identified by the practice papers, using your own notes and reference sheets.

Recite from memory the class list, the placarding thresholds, the transport document entries and the emergency actions for a spill and a fire.

Review every error from the practice papers and write a one-line correction for each to prevent repeat mistakes.

Confirm logistics for exam day, including permitted reference material, identification and timing.
