Hazardous
Chemical Definitions
Poison Gas ----- Extremely dangerous poisons, highly toxic poisonous
gases or liquids - a very small amount of the gas, or vapor of the liquid,
mixed with air is dangerous to life.
Poison ---- Less dangerous poison , toxic - Substances,
liquid or solids (including pastes, and semi-solids) so toxic to man that
they are a hazard to health during transportation.
Flammable Gas ----- A gas that can bum with the evolution of heat
and a flame. Flammable compressed gas is any compressed gas of which: (1) a
mixture of 13 % or less (by volume) with air is flammable, or (2) the
flammable range with air is under 12%.
Non-Flammable Gas ----- Any compressed gas other than a flammable
compressed gas
Flammable Liquid ----- Any liquids having a flash point below 100
degrees F (37.8 degrees Q, except any mixture having components with flash
points of 100 degrees F (37.8 degrees Q, or higher, the total of which
makes up 99 % or more of the total volume of the mixture.
Combustible Liquid ----- Any liquid having a flash point at or above
100 degrees F (3 7.8 degrees Q, but below 200 degrees F (93.3 degrees Q,
except an3 mixture having components with flash points of 200 degrees F
(93.3 degrees Q, or higher, the total volume of which make up 99 % or more
of the volume of the mixture
Corrosives - Liquid and Solid ----- Any liquid or solid that causes
visible destruction or irreversible damage to human skin tissue, Also, it
may be a liquid that has a severe corrosion rate on steel.
Irritating Material - Liquid and Solid ----- A liquid or solid
substance which, upon contact with fire or air, gives off dangerous or
intensely irritating fumes.
Explosive and Blasting Agent (Not Including Class C Explosives)
----- "Explosive" means a chemical that causes a sudden, almost
instantaneous release of pressure, gas, and heat when subjected to sudden
shock, pressure, or high temperature. "Blasting Agent" is a
material designed for blasting. It must be so insensitive that there is
very little probability of (1) accidental explosion or (2) going from
burning to detonation.
Radioactive Material - (Yellow 1H Label) ----- Any material, or
combination of materials, that spontaneously gives off ionizing radiation.
Flammable Solid (Dangerous When Wet) ----- Water Reactive Material
(Solid) - Any solid substance (including sludges and pastes) which react
with water by igniting or giving off dangerous quantities of flammable or
toxic gases.
Flammable Solid ----- A solid, other than a blasting agent, or
explosive, that is liable to cause fire through friction, absorption of
moisture, spontaneous chemical change, or retained heat from manufacturing
or processing, or which can be ignited readily and when ignited burns so
vigorously and persistently as to create a serious hazard,
Spontaneously Combustible Material ---- Spontaneously Combustible
Material (Solid) - A solid substance (including sludges and pastes) which
may undergo spontaneous heating or self-burning under normal transportation
conditions. These materials may increase in temperature and ignite when
exposed to air.
Oxidizer ------ A chemical that initiates or promotes cornbuition in
other materials, thereby causing fire either of itself or through the
release of oxygen or other gases. Example being: Chlorate, permanganate,
inorganic peroxide, or a nitrate, that yields oxygen readily.
Organic Peroxide ----- Means an organic compound that contains the
bivalent -0-0 structure and which may be considered to be a structural
derivative of hydrogen peroxide where one or both of the hydrogen atoms has
been replaced by an organic radical.
Carcinogen A chemical is considered to be a carcinogen if
