This Article shall apply to materials not otherwise covered in this 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 and shall also apply to flammable liquids which are chemically unstable and which may spontaneously form explosive compounds or undergo spontaneous reactions of explosive violence or with sufficient evolution of heat to be a fire hazard. Hazardous chemicals shall include such materials as flammable solids, corrosive liquids, radioactive materials, oxidizing materials, potentially explosive chemicals, highly toxic materials and poisonous gases, as defined in §
35-47.
As used in this chapter, the following terms shall have the meanings
indicated:
CORROSIVE LIQUID
Includes those acids, alkaline caustic liquids and other corrosive
liquids which, when in contact with living tissue, will cause severe damage
of 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 will cause the release of their contents or which 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 change or as a result of retained heat from manufacturing
or processing.
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
Includes substances such as chlorates, permanganates, peroxides or
nitrates that yield oxygen readily to stimulate combustion.
POISONOUS GAS
Includes any noxious gas of such nature that a small amount of the
gas when mixed with air is dangerous to life. Examples are chlorpicrin, cyanogen,
hydrogen cyanide, nitrogen peroxide and phosgene.
POTENTIALLY EXPLOSIVE CHEMICAL
Includes any chemical substance, other than one classified as an
explosive or blasting agent, which has a tendency to be unstable and which
can be exploded by heat or shock or a combination thereof.
RADIOACTIVE MATERIAL
Includes any material or combination of material that spontaneously
emits ionizing radiation.
SEALED SOURCE
A quantity of radiation so enclosed as to prevent the escape of any
radioactive material but at the same time permitting radiation to come out
for use.
Packaged oxidizing materials shall be stored in dry locations and separated
from stored organic 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.
No connection with or opening into any gutter leading into any sewer
or drain, either public or private, shall be used for the conveyance or discharge,
directly or indirectly, into said sewer or drain of any volatile flammable
liquid, gas or vapor; it being noted that a volatile flammable liquid is any
liquid that will emit flammable vapor at a temperature below one hundred sixty
degrees Fahrenheit (160º F.).
