The following words, terms and phrases, when
used in this article, shall have the meanings ascribed to them in
this section, except where the context clearly indicates a different
meaning:
CORROSIVE LIQUID
Those acids, alkaline caustic liquids and other corrosive
liquids which, when in contact with living tissue, will cause severe
damage to such tissue by chemical action; or in case of leakage will
materially damage or destroy other containers of other hazardous commodities
by chemical action and cause the release of their contents; or are
liable to cause fire when in contact with organic matter or with certain
chemicals.
FLAMMABLE SOLID
A solid substance, other than one classified as an explosive,
which is liable to cause fires through friction, through absorption
of moisture, through spontaneous chemical changes or as a result of
retained heat from manufacturing or processing. Examples are white
phosphorus, nitrocellulose, metallic sodium and potassium and zirconium
powder.
HIGHLY TOXIC MATERIAL
A material so toxic to man as to afford an unusual hazard
to life and health during fire fighting operations. Examples are parathion,
TEPP (tetraethyl phosphate), HETP (hexaethyl tetraphosphate) and similar
insecticides and pesticides.
OXIDIZING MATERIAL
Substances that yield oxygen readily to support combustion.
Examples are chlorates, pci-manganates, peroxides and nitrates.
POISONOUS GAS
Any noxious gas of such nature that a small amount of the
gas in air is dangerous to life. Examples are chlorine, cyanogen,
fluorine, hydrogen cyanide, nitric oxide, nitrogen tetraoxide and
phosgene.
RADIOACTIVE MATERIAL
Any material or combination of material that spontaneously
emits ionizing radiation.
UNSTABLE (REACTIVE) CHEMICAL
Any substance, other than one classified as an explosive
or blasting agent, which will vigorously and energetically react,
is potentially explosive, will polymerize, decompose instantaneously,
undergo uncontrollable auto-reaction or can be exploded by heat, shock,
pressure or combinations thereof. Examples are organic peroxides,
nitromethane and ammonium nitrate.
This article shall apply to materials not otherwise covered in this Part
1 which are highly flammable or which may react to cause fires or explosions, or which by their presence create or augment a fire or explosion hazard, or which because of their toxicity, flammability or liability to explosion render fire fighting abnormally dangerous or difficult; also to materials and formulations which are chemically unstable and which may spontaneously form explosive compounds, or undergo spontaneous or exothermic reactions of explosive violence or with sufficient evolution of heat to be a fire hazard. Hazardous chemicals shall include such materials as corrosive liquids, flammable solids, highly toxic materials, oxidizing materials, poisonous gases, radioactive materials and unstable chemicals, as defined in §
198-66.
Packaged oxidizing materials shall be stored
in dry locations and separated from stored organic and other combustible
materials. Bulk oxidizing materials shall not be stored on or against
wooden surfaces.
Satisfactory provisions shall be made for containing
and neutralizing or safely flushing away leakage of corrosive liquids
which may occur during storage or handling.
