Gases which are
compressed, liquefied or dissolved under pressure as detailed below.
Some gases have subsidiary risk classes; poisonous or corrosive.
Hazardous Materials
Class 2.1: Flammable Gas
Hazardous Materials
Class 2.2: Nonflammable Gas
Hazardous Materials
Class 2.3: Poisonous Gas
Hazardous Materials
Class 2.2: Oxygen (Alternate Placard)
Hazardous Materials
Class 2.3: Inhalation Hazard
2.1
Flammable Gas:
Gases which ignite on contact with an ignition source, such as acetylene and hydrogen.
2.2
Non-Flammable Gases:
Gases which are
neither flammable nor poisonous. Includes the cryogenic gases/liquids
(temperatures of below -100°C) used for cryopreservation and rocket
fuels, such as nitrogen and neon.
2.3
Poisonous Gases:
Gases liable to cause death or serious injury to human health if inhaled; examples are fluorine, chlorine, and hydrogen cyanide.
Class 3: Flammable Liquids
Flammable liquids included in Class 3 are included in one of the following packing groups:
Packing group 2
If they have an
initial boiling point of 35°C or less at an absolute pressure of 101.3
kPa and any flash point, such as diethyl ether or carbon disulfide;
Packing group 1
If they have an
initial boiling point of 35°C or less at an absolute pressure of 101.3
kPa and any flash point, such as diethyl ether or carbon disulfide;
Packing group 3
If the criteria for inclusion in Packing Group I or II are not met, such as kerosene and diesel.

Class 4: Flammable Solids
Hazardous Materials
Class 4.1: Flammable Solids
Hazardous Materials
Class 4.2: Spontaneously Combustible Solids
Hazardous Materials
Class 4.3: Dangerous when Wet
4.1
Flammable Solids:
Solid substances that are easily ignited and readily combustible (nitrocellulose, magnesium, safety or strike-anywhere matches).
4.2
Spontaneously Combustible: Solid substances that ignite spontaneously (aluminium alkyls, white phosphorus).
4.3
Dangerous when Wet:
Solid substances that emit a flammable gas when wet or react violently with water (sodium, calcium, potassium, calcium carbide).
Class 5: Oxidizing Agents and Organic Peroxides
Hazardous Materials
Class 5.1: Oxidizing Agent
Hazardous Materials
Class 5.2: Organic Peroxide Oxidizing Agent
5.1
Oxidizing agents other than organic peroxides (calcium
hypochlorite, ammonium nitrate, hydrogen peroxide,
potassium permanganate).
5.2
Organic peroxides, either in liquid or solid form (benzoy
peroxides, cumene hydroperoxide).
Class 6: Toxic and Infectious Substances
Hazardous Materials
Class 6.1: Poison
Hazardous Materials
Class 6.2: Biohazard
6.1
6.1a Toxic substances which are liable to cause death or serious injury to human
health if inhaled, swallowed or by skin absorption (potassium cyanide, mercuric
chloride).
6.1b (Now PGIII) Toxic substances which are harmful to human health (N.B this
symbol is no longer authorized by the United Nations) (pesticides, methylene
chloride).
6.2
Biohazardous substances; the World Health Organization (WHO) divides this
class into two categories: Category A: Infectious; and Category B: Samples
(virus cultures, pathology specimens, used intravenous needles).
Class 8: Corrosive Substances
Hazardous Materials
Class 8: Corrosive
8.1 Acids
sulfuric acid, hydrochloric acid
8.2 Alkalis
potassium hydroxide, sodium hydroxide
Hazardous Materials
Class 9: Miscellaneous
9
Hazardous substances that do not fall into the other categories (asbestos,
air-bag inflators, self inflating life rafts, dry ice).
