This article shall apply to materials not otherwise
covered in the New York State Fire Prevention and Building Code or
Flammable Liquid Code 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 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 used in this article, the following terms
shall have the meanings indicated:
CORROSIVE LIQUIDS
Includes those acids, alkaline caustic liquids, and other
corrosive liquids which when in contact with living tissues, will
cause severe damage of such tissue by chemical action; or in the 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
Includes 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 phosphorous, 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.
ISOLATED STORAGE
Storage away from incompatible materials in a different storage
room or in a separate and detached building located at a safe distance
from hazardous occupancies and important exposures.
OXIDIZING MATERIAL
Includes any substances that yield oxygen readily to support
combustion. Examples are: chlorates, permanganates, peroxides and
nitrates.
POISONOUS GAS
Includes any noxious gas of such nature that a small amount
of the gas in the air is dangerous to life. Examples are: chlorine,
cyanogen, fluorine, hydrogen cyanide, nitric oxide, nitrogen tetraoxide,
phosgene.
RADIOACTIVE MATERIAL
Includes any material or combination of materials that spontaneously
emits ionizing radiation.
SEALED SOURCE
A quantity of radiation so enclosed as to prevent the escape
of any radioactive materials but at the same time permitting radiation
to come out for use.
SEPARATE STORAGE
Storage in the same fire area but physically separated by
as much space as practicable, using skills or curbs as safeguards
for intervening storage of nonhazardous, compatible commodities.
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 be exploded by heat, shock,
pressure or combinations thereof. Examples are: organic peroxides,
nitromethane and ammonium nitrate.
Packaged oxidizing materials shall be stored
in dry locations and separated from organic and other combustible
materials. Bulk oxidizing materials shall not be stored on or against
wooden surfaces.
Highly toxic materials shall be separated from
other chemicals and combustible and flammable substances by storage
in a room or compartment separated from other areas by walls and floor
and ceiling assemblies having a fire resistive rating of not less
than one hour. The storage room shall be provided with adequate drainage
facilities and natural or mechanical ventilation to the outside atmosphere.
Legible warning signs and placards stating the nature and location
of the highly toxic materials shall be posted at all entrances to
areas where such materials are stored or used.
Storage of poisonous gases shall be in rooms
of at least one hour fire resistive construction and having natural
or mechanical ventilation adequate to remove leaking gas. Such ventilation
shall not discharge to a point where the gases may endanger any person.
Legible warning signs stating the nature of hazards shall be placed
at all entrances to locations where poisonous gases are stored or
used.
Satisfactory provisions shall be made for containing
and neutralizing or safely flushing away leakage of corrosive liquids
which may occur during storage or handling.
Durable, clearly visible signs warning of radiation
shall be placed at all entrances to areas or rooms where radioactive
materials are used or stored. Each container in which radioactive
materials are used or transported shall bear a durable, clearly visible,
appropriate warning sign. Such signs shall be posted to provide reasonable
safety to persons and property. Exception: Signs are not required
for storage of manufactured articles other than liquids, such as instruments
on clock dials or electronic tubes or apparatus of which radioactive
materials are a component part, provided that the gamma radiation
at any surface of the package is less than 10 Milliroentgen in 24
hours. When not in use radioactive materials shall be kept in adequately
shielded fire resistive containers.
