1According to the Classification and Code of Dangerous Goods (GB 6944-2012) and the List of Dangerous Goods (GB 12268-2012), into how many hazard classes are dangerous goods divided for road transportation?

A.9 primary hazard classes

B.7 primary hazard classes

C.12 primary hazard classes

D.5 primary hazard classes

Explanation: Under GB 6944-2012 and GB 12268-2012, dangerous goods are categorized into 9 primary hazard classes based on their intrinsic physical, chemical, and physiological hazards. These classes range from Class 1 (Explosives) to Class 9 (Miscellaneous Dangerous Substances and Articles), aligning with the United Nations Model Regulations on the Transport of Dangerous Goods.

2Under GB 6944-2012, which of the following explosive divisions comprises substances and articles that present a mass explosion hazard (整体爆炸危险) affecting virtually the entire load instantaneously?

A.Division 1.1

B.Division 1.2

C.Division 1.3

D.Division 1.4

Explanation: Division 1.1 consists of substances and articles which have a mass explosion hazard (整体爆炸危险), meaning the entire quantity detonates almost instantaneously upon initiation (such as TNT or dynamite). Division 1.2 presents projection hazards without mass explosion, Division 1.3 presents fire hazards and minor blast/projection hazards, and Division 1.4 presents no significant blast hazard.

3Consumer fireworks, small arms cartridges, and distress flares classified under Division 1.4 are characterized primarily by which hazard profile during transport?

A.They present no significant blast hazard, and explosive effects are largely confined to the package

B.They detonate instantaneously with intense shockwaves capable of collapsing adjacent bridge structures

C.They release dense clouds of highly toxic systemic blood poisons upon combustion

D.They spontaneously ignite upon contact with ambient humidity at room temperature

Explanation: Under GB 6944-2012, Division 1.4 comprises explosive substances and articles that present no significant hazard (无重大危险的物质和物品). Any explosive effects during transit or accidental ignition are predominantly confined within the packaging, without throwing dangerous fragments of appreciable size beyond nominal distances.

4Which of the following gases is classified under Division 2.1 Flammable Gases (易燃气体) under GB 6944-2012 and JT/T 617.2?

A.Liquefied Petroleum Gas (液化石油气, UN 1075)

B.Compressed Nitrogen (压缩氮气, UN 1066)

C.Liquid Chlorine (液氯, UN 1017)

D.Carbon Dioxide (二氧化碳, UN 1013)

Explanation: Under GB 6944-2012, Division 2.1 covers flammable gases that are ignitable when in a mixture of 13% or less by volume with air, or have a flammable range with air of at least 12 percentage points regardless of lower limit. Liquefied Petroleum Gas (LPG, UN 1075) and Hydrogen (UN 1049) are typical Division 2.1 flammable gases.

5When transporting refrigerated liquefied cryogenic gases classified under Division 2.2 (such as Liquid Nitrogen UN 1977 or Liquid Argon UN 1951), what is the primary occupational health and safety hazard in an enclosed compartment or low-lying space?

A.Rapid asphyxiation (窒息) resulting from oxygen displacement as the cryogenic liquid vaporizes and expands hundreds of times in volume

B.Violent chemical polymerization releasing flammable hydrocarbon vapors

C.Spontaneous detonation caused by mechanical road vibration

D.Immediate bioaccumulation and systemic carcinogenicity upon skin contact

Explanation: Cryogenic liquids under Division 2.2 (Non-flammable, non-toxic gases) vaporize rapidly into enormous gas volumes (e.g. 1 liter of liquid nitrogen expands to ~700 liters of gas at ambient conditions). In enclosed cabs, cargo compartments, or low-lying road swales, this rapid expansion drastically reduces atmospheric oxygen concentration below 19.5%, leading to sudden asphyxiation and severe cold-contact frostbite.

6Under GB 6944-2012, what is the statutory lethal concentration threshold (LC50) for a gas to be classified under Division 2.3 Toxic Gases (毒性气体)?

A.Inhalation LC50 (lethal concentration for 50% test population over 4 hours) of not more than 5,000 mL/m³ (ppm)

B.Inhalation LC50 of not more than 20,000 mL/m³ (ppm)

C.Inhalation LC50 of not more than 50,000 mL/m³ (ppm)

D.Inhalation LC50 of not more than 100 mL/m³ (ppm)

Explanation: According to GB 6944-2012 and JT/T 617.2, Division 2.3 Toxic Gases are defined as gases known to be so toxic or corrosive to humans as to pose a hazard to health, or presumed to be toxic because they have an acute inhalation toxicity LC50 of not more than 5,000 mL/m³ (ppm) when tested on albino rats for 4 hours.

7Under GB 6944-2012 and JT/T 617.2, what is the closed-cup flash point (闭杯闪点) upper limit for a substance to be classified as a Class 3 Flammable Liquid (易燃液体)?

A.Closed-cup flash point not greater than 60°C

B.Closed-cup flash point not greater than 93°C

C.Closed-cup flash point not greater than 23°C

D.Closed-cup flash point not greater than 100°C

Explanation: Under GB 6944-2012 and JT/T 617.2, Class 3 Flammable Liquids are defined as liquids, mixtures of liquids, or liquids containing solids in solution or suspension which give off a flammable vapor at temperatures of not more than 60°C in a closed-cup test (or not more than 65.6°C in an open-cup test).

8How are Packing Groups (包装类别) assigned to Class 3 Flammable Liquids according to their flash point and initial boiling point under JT/T 617.2?

A.Packing Group I: Initial boiling point ≤ 35°C; Packing Group II: Flash point < 23°C and initial boiling point > 35°C; Packing Group III: Flash point 23°C to 60°C and initial boiling point > 35°C

B.Packing Group I: Flash point < 0°C; Packing Group II: Flash point 0°C to 50°C; Packing Group III: Flash point > 50°C

C.Packing Group I: Flash point < 23°C; Packing Group II: Flash point 23°C to 60°C; Packing Group III: Flash point 60°C to 93°C

D.Packing Group I: Initial boiling point > 100°C; Packing Group II: Initial boiling point 50°C to 100°C; Packing Group III: Initial boiling point < 50°C

Explanation: According to JT/T 617.2 and GB 6944-2012, Class 3 substances are grouped by degree of danger: Packing Group I (High Danger) has an initial boiling point ≤ 35°C (e.g. diethyl ether); Packing Group II (Medium Danger) has a flash point < 23°C and initial boiling point > 35°C (e.g. gasoline, acetone); Packing Group III (Low Danger) has a flash point from 23°C to 60°C and initial boiling point > 35°C (e.g. kerosene).

9Commercial diesel fuel (柴油) transported in bulk road tankers in China is officially assigned to which UN Number and hazard classification?

A.UN 1202, Class 3 Flammable Liquid (Packing Group III)

B.UN 1203, Class 3 Flammable Liquid (Packing Group I)

C.UN 1993, Class 9 Miscellaneous Dangerous Substance

D.UN 3082, Class 8 Corrosive Liquid

Explanation: Under GB 12268-2012 and JT/T 617.2, diesel fuel (Gas oil / Diesel fuel / Heating oil light) is classified under UN 1202 as a Class 3 Flammable Liquid, Packing Group III, having a flash point typically between 55°C and 75°C. Motor gasoline, by contrast, is classified under UN 1203, Class 3, Packing Group II.

10Which of the following substances is classified under Division 4.1 Flammable Solids (易燃固体) under GB 6944-2012?

A.Red Phosphorus (红磷, UN 1338)

B.White Phosphorus (白磷, UN 1381)

C.Metallic Sodium (金属钠, UN 1428)

D.Potassium Permanganate (高锰酸钾, UN 1490)

Explanation: Under GB 6944-2012, Division 4.1 includes readily combustible solids that can easily ignite through brief contact with an ignition source and burn rapidly (e.g. Red Phosphorus UN 1338, Sulfur UN 1350). In contrast, White Phosphorus is a Division 4.2 spontaneously combustible substance, Metallic Sodium is a Division 4.3 water-reactive metal, and Potassium Permanganate is a Division 5.1 oxidizer.
