Safety Fuses, some type of Fireworks, etc.
Division 2.1 Description
Flammable Gas
Any gases which, when mixed with air in
certain proportions,
Forms a flammable mixture.
RFG
Example: Butane, Hydrogen, Propane, Acetylene, Lighters
Hazard Label
Division 2.2
Non-Flammable Any non-flammable, nontoxic
gas or refrigerated.
Non-Toxic gas
liquefied gas
RNG or RCL
Example: Carbon dioxide, Neon, Fire Extinguisher, liquefied Nitrogen
or Helium
Division 2.3
Toxic Gas Gases
known to be toxic or corrosive to humans and known.
RPG to pose a health risk.
Example: Most toxic gases are forbidden for carriage
by air; some are permitted, e.g. aerosols of low toxicity, tear gas devices.
CALSS 3 – FLAMMABLE LIQUIDS
Flammable Liquid Any liquid having a
close-cup flash point of 60 degree C or below.
Or
not more than 65.6 degree C open-cup test (DGR Appendix A) and liquid
RFL
Explosives
Example: Certain Paints, Varnishes, Alcohols, some Adhesives,
Acetone,
Petrol, Fuel etc.
CLASS 4 – FLAMMABLE SOLIDS; SUBTANCES LIABLE TO
SPONTANEOUS COMBUSTION; SUBSTANCES WHICH, IN CONTACT WITH WATER, EMIT FLAMMABLE
GASES
This classis is divided into 3 divisions:
Division 4.1 Flammable solid
Flammable solid, Self- Any solid material,
which is readily combustible, or may
Reactive Substances; cause or
contribute to fire through friction, self- reactive
Polymerizing Substances Substances and
polymerizing Which are liable to undergo a
And desensitized strongly exothermic
reaction; desensitized explosives which.
Explosive. may
explode if not diluted sufficiently.
RFS
Example: Matches, Sulphur, Celluloid, Acrylic polymers, polyethylene
etc.
Division 4.2 Substances Liable to Spontaneous Combustion
Spontaneously Such substances
are liable to spontaneous heating or to
Combustible heating up in contact with air and then liable to catch fire.
this occurs when the
rate of Heat production exceeds the rate.
of heat loss and the
auto-ignition Temperature is reached
RSC
Example: White and Yellow phosphorus, Magnesium diamide.
Division 4.3 Substances which, in contact with Water, Emit Flammable Gases
(Dangerous when wet)
Dangerous When Wet Substances, which
by interaction with water are liable to become.
spontaneously flammable or give
of flammable gases.
RFW
Example: Calcium carbide, sodium
CLASS 5 –OXIDIZING SUBSTANCES AND ORGANIC PEROXIDES
These classes divided into 2 divisions:
Division 5.1 Oxidizing substances
Oxidizer
A substance that yields oxygen Readily to stimulate the
Combustion of the material
ROX
Example: Ammonium nitrate fertilizer, calcium chlorate, bleaches.
Division 5.2 Organic Peroxides
Organic peroxide An organic material
(liquid or solid) that can be lighted readily by
external flame and then burns with an accelerating rate: some.
Substances react dangerously with others.
ROP
Example: tert-Butyl hydro peroxide
CLASS 6 – TOXIC and INFECTIOUS SUBSTANCES
This classis is divided into 2 divisions:-
Division 6.1 Toxic Substance
Toxic substance Liquids or
solids, which are dangerous If inhaled, swallowed.
or absorbed through the skin.
RPB
Example : Arsenic,
Nicotine, Cyanide, Pesticides, Strychnine.
Note: some are totally forbidden, e.g. Bromoacetone
Division 6.2 Infectious Substance
Infectious Substance Substances which are
known or reasonably expected to
contain pathogens and cause Disease in humans or in animals.
RIS
Example: Virus, Bacteria, such as HIV (AIDS), Rabies,
some diagnostic specimens and Medical and Clinical waste
