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 tissue, will cause severe damage of such tissue by chemical action or, in case of leakage, will materially damage or destroy other containers or 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. Corrosive liquids are those that have a pH less than four or greater than 10.

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 or during an unintended release of said material into the environment. 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 materials 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.
