Dangerous Goods Specification

Dangerous Goods Specification


Class 1: Explosives Subclass 1.1: Explosives with a mass explosion hazard Consists of explosives that have a mass explosion hazard. A mass explosion is one which affects almost the entire load instantaneously. Subclass 1.2: Explosives with a severe projection hazard Consists of explosives that have a projection hazard but not a mass explosion hazard. Subclass 1.3: Explosives with a fire Consists of explosives that have a fire hazard and either a minor blast hazard or a minor projection hazard or both but not a mass explosion hazard. Subclass 1.4: Minor fire or projection hazard Consists of explosives that present a minor explosion hazard. The explosive effects are largely confined to the package and no projection of fragments of appreciable size or range is to be expected. An external fire must not cause virtually instantaneous explosion of almost the entire contents of the package.

    Subclass 1.5: An insensitive substance with a mass explosion hazard
Consists of very insensitive explosives with a mass explosion hazard (explosion similar to 1.1). This division is comprised of substances which have a mass explosion hazard but are so insensitive that there is very little probability of initiation or of transition from burning to detonation under normal conditions of transport.
    Subclass 1.6: Extremely insensitive articles
Consists of extremely insensitive articles which do not have a mass explosive hazard. This division is comprised of articles which contain only extremely insensitive detonating substances and which demonstrate a negligible probability of accidental initiation or propagation.

Class 2: Gasses


Subclass 2.1: Flammable Gas
Gases which ignite on contact with an ignition source, such as acetylene and hydrogen. Flammable gas gas means any material which is ignitable at 101.3 kPa (14.7 psi) when in a mixture of 13 percent or less by volume with air, or has a flammable range at 101.3 kPa (14.7 psi) with air of at least 12 percent regardless of the lower limit

Subclass 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. This division includes compressed gas, liquefied gas, pressurized cryogenic gas, compressed gas in solution, asphyxiant gas and oxidizing gas. A non-flammable, nonpoisonous compressed gas means any material which exerts in the packaging an absolute pressure of 280 kPa (40.6 psia) or greater at 20°C (68°F), and does not meet the definition of Division 2.1 or 2.3.

Subclass 2.3: Poisonous Gases
Gases liable to cause death or serious injury to human health if inhaled. Gas poisonous by inhalation means a material which is a gas at 20°C or less and a pressure of 101.3 kPa (a material which has a boiling point of 20°C or less at 101.3kPa (14.7 psi)) which is known to be so toxic to humans as to pose a hazard to health during transportation, or in the absence f adequate data on human toxicity, is presumed to be toxic to humans because when tested on laboratory animals it has an LC50 value of not more than 5000 ml/m3.


Class 3: Flammable liquids


A flammable liquid means a liquid which may catch fire easily or any mixture having one or more components whith any flash point. As example: acetone, diesel, gasoline, kerosene, oil etc. There is strongly recomended for transportation at or above its flash point in a bulk packaging. There are three main groups of flammable liquid.

  1. Low flash point – liquids with flash point below -18°C
  2. Intermediate flash point – liquids with flash point from -18°C. up to +23°C
  3. High flash point group – liquids with flash point from +23°C


Class 4: Flammable solids or substances


Subclass 4.1: Flammable solids
Solid substances that are easily ignited. Self-reactive materials, which are thermally unstable and that can undergo a strongly exothermic decomposition even without participation of air. Readily combustible solids that can cause a fire through friction and show a burning rate faster than 2.2 mm (0.087 inches) per second, or metal powders that can be ignited and react over the whole length of a sample in 10 minutes or less.


Subclass 4.2: Spontaneously combustible solids
Solid substances that ignite spontaneously. Spontaneously combustible material is a pyrophoric material, which is a liquid or solid that can ignite within five minutes after coming in contact with air or a self-heating material that when in contact with air and without an energy supply is liable to self-heat.
