HAZARDOUS CHEMICAL DEFINITIONS
Carcinogen -
A chemical is considered to be a carcinogen if: 1) It has been evaluated
by the International Agency for Research on Cancer (IARC) and found to
be a carcinogen or potential carcinogen or 2) It is listed as a
carcinogen or potential carcinogen in the Annual Report on Carcinogens
published by the National Toxicology Program (NTP) (latest edition) or
3) It is regulated by OSHA as a carcinogen.
Combustible Liquid -
Any liquid having a flashpoint at or above 100 degrees F (37.8 degrees
C), but below 200 degrees F (93.3 degrees C), except any mixture having
components with flashpoints of 200 degrees F (93.3 degrees C), or
higher, the total volume of which make up 99 percent 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.
Explosives and Blasting Agents - (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" means a material designed
for blasting. It must also be so insensitive that there is very little
probability of: 1) accidental explosion or 2) going from burning to
detonation.
Flammable Liquid -
Any liquid having a flashpoint below 100 degrees F (37.8 degrees C),
except any mixture having components with flashpoints of 100 degess F
(37.8 degrees C) or higher, the total of which makes up 99 percent or
more of the total volume of the mixture.
Flammable Gas -
A gas that can burn with the evolution of heat and a flame. Flammable
compressed gas is any compressed gas of which: 1) a mixture of 13
percent or less (by volume) with air is flammable or 2) the flammable
range with air is under 12 percent.
Flammable Solid -
A solid, other than a blasting agent or explosive, that is liable to
cause fire through friction, absorption or 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.
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.
Irritating Material - Liquid and Solid -
A liquid or solid substance which, upon contact with fire or air, gives
off dangerous or intensely irritating fumes.
MISC. -
Any materials not described as hazardous: Examples; plastics, pallets
(in piles), etc.
Non-Flammable Gas -
Any compressed gas other than a flammable compressed gas.
Organic Peroxide -
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.
Oxidizer -
A chemical that initiates or promotes combustion in other materials,
thereby causing fire either of itself or through the release of oxygen
or other gases. Examples; chlorate, permangante, inorganic peroxide or a
nitrate, that yields oxygen readily.
Poison -
Less dangerous poisons, toxic
- substances, liquids or solids (including pastes and semi-solids) so
toxic to man that they are a hazard to health during transportation.
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.
Radioactive Material (Yellow 111 Label) -
Any material, or combination of materials, that spontaneously gives off
ionizing radiation.
Spontaneously Combustible Material - (Solid) - A solid (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.
