Which UN class is assigned to gasoline?
Class 1 (Explosives)
Class 2 (Gases)
Class 3 (Flammable Liquids)
Class 4 (Flammable Solids)
Gasoline is a flammable liquid, which places it in UN Class 3. Class 3 specifically covers substances with a flash point below 60 °C. Other classes cover different hazard types such as gases, solids, or explosives.
What is the proper shipping name for UN 1203?
Diesel Fuel
Gas Oil
Aviation Turbine Fuel
Gasoline
UN 1203 is the designation for gasoline in transport regulations. Diesel fuel (UN 1202) and gas oil have different UN numbers. The proper shipping name must match the UN number exactly.
Which label is required for a corrosive substance?
Toxic
Corrosive
Explosive
Flammable Liquid
Corrosive substances must bear the corrosive label, which depicts test tubes pouring liquid onto a surface and a hand. This label warns handlers of the potential to cause chemical burns. Other labels correspond to different hazard classes.
What is the term for the primary container that directly holds a dangerous good?
Primary Packaging
Secondary Packaging
Overpack
Tertiary Packaging
Primary packaging refers to the container that is in direct contact with the dangerous good. Secondary packaging encloses one or more primary containers. Tertiary packaging or overpacks group secondary packages for handling.
Which transport document is mandatory for road shipments of dangerous goods under ADR?
Shipper's Declaration for Dangerous Goods
Bill of Lading
Commercial Invoice
Packing List
The Shipper's Declaration for Dangerous Goods is required under ADR to certify that the shipment complies with regulations. Commercial invoices and packing lists are commercial documents but do not replace the dangerous goods declaration. A bill of lading may accompany transport but is not the declaration itself.
Which packing group indicates the highest level of danger for a substance?
Packing Group IV
Packing Group III
Packing Group II
Packing Group I
Packing Group I is assigned to substances presenting high danger. Packing Group II indicates medium danger and Packing Group III indicates low danger. There is no Packing Group IV in UN classification.
According to GHS, which hazard statement code indicates "Highly flammable liquid and vapour"?
H220
H302
H400
H225
H225 is the GHS hazard statement for "Highly flammable liquid and vapour." H220 refers to extremely flammable gases. H302 and H400 refer to acute toxicity and aquatic toxicity, respectively.
Which pictogram must appear on a gas cylinder containing a compressed gas?
Skull and Crossbones
Exclamation Mark
Gas Cylinder
Flame
The gas cylinder pictogram indicates gases under pressure. Flammable and toxic pictograms cover other hazards. The cylinder symbol warns handlers of the pressure risk.
Under limited quantity provisions, what marking is required on the outer packaging?
Skull and crossbones
Black and white diamond with a "Y"
Red border flammable label
UN shipping name in full
Limited quantity shipments under UN regulations use a black and white diamond mark with a "Y" to indicate the package meets limited quantity criteria. This marking replaces standard hazard labels in small shipments.
Under ADR, how must bulk tanks display the UN number?
On two opposite sides in orange panels
No display required
On one end only
On all four sides in black text
ADR bulk tanks must show the UN number on two opposite sides in orange panels. This ensures visibility from either side during transport inspections. Other display options do not meet ADR requirements.
Which hazard class must be segregated from Class 3 (Flammable Liquids) in storage?
Class 8 (Corrosives)
Class 2.1 (Flammable Gases)
Class 4.1 (Flammable Solids)
Class 5.1 (Oxidizers)
Flammable liquids (Class 3) must be segregated from oxidizers (Class 5.1) to prevent intense fires. Other classes have different incompatibilities but oxidizers present the greatest risk when mixed with flammable liquids.
What is the UN number for a 70% ethanol solution?
UN1987
UN1170
UN3082
UN3316
UN1170 is assigned to ethanol solutions above 24% by volume. UN1987 covers alcohols, n.o.s., but ethanol has its own number. The others refer to patient specimens and environmentally hazardous substances.
Under GHS, which class does dry ice (solid carbon dioxide) belong to?
Class 9 (Miscellaneous Hazards)
Class 7 (Radioactive)
Class 2 (Gases)
Class 6.2 (Infectious Substances)
Dry ice is classified as Class 9 (Miscellaneous Hazards) because it sublimates to CO₂ gas and poses suffocation and pressure risks. It is not a gas, infectious, or radioactive material.
Which label is required for Class 9 miscellaneous dangerous goods?
Skull and crossbones
Red flame
Black and white vertical stripes
Corrosive symbol
Class 9 goods use a black and white vertical stripes pictogram. The design warns of miscellaneous hazards not covered by other classes. Other symbols represent different specific hazards.
In a spill involving a Class 2.3 toxic gas, what respiratory protection is required?
Half-mask with organic cartridges
Dust mask
Self-Contained Breathing Apparatus (SCBA)
No respiratory protection
Class 2.3 toxic gases require SCBA to protect from inhalation of deadly gas. Cartridge respirators cannot filter out high-toxicity gases effectively. No protection would risk severe poisoning.
During a spill of sodium hydroxide solution, what should an emergency responder do first?
Dilute with large volumes of water
Neutralize with acid immediately
Don chemical-resistant personal protective equipment
Sweep up solids with a broom
The first priority is to don suitable chemical-resistant PPE before approaching the spill. This protects the responder from chemical burns. Neutralization and cleanup follow only after proper protection is in place.
What is the required drop test height for a package in Packing Group II under UN performance tests?
2.0 meters
1.8 meters
0.8 meters
1.2 meters
Packing Group II packages must withstand a 1.2 m drop test. Packing Group I requires 1.8 m and Packing Group III requires 0.8 m. These heights simulate typical handling shocks.
For a mixed load containing UN 1090 (Acetone) and UN 1202 (Diesel Fuel) under ADR, what segregation rule applies?
Allowed only if in the same inner packaging
Must be separated by at least 3 m or a full partition
May be loaded together without restrictions
Must not be loaded in the same vehicle
Acetone (Class 3) and diesel fuel (Class 3) can be carried together but require segregation from oxidizers. However, mixtures of flammable liquids sometimes need a partition or 3 m separation under ADR load segregation rules. A full partition meets that requirement.
A substance with a flash point of 65 °C falls into which packing group?
Not classified as a flammable liquid
Packing Group I
Packing Group II
Packing Group III
Flammable liquids with flash points between 23 °C and 60 °C are in Packing Group II, and those above 60 °C up to 93 °C are in Packing Group III. A 65 °C flash point therefore falls into Packing Group III.
In an anhydrous ammonia release incident, what isolation distance is recommended for a small spill?
45 meters
200 meters
15 meters
100 meters
For a small spill of anhydrous ammonia (UN1005), an initial isolation distance of 45 m is recommended. This protects responders and bystanders from toxic vapors. Larger spills require greater distances.
