      Sec. 29-336. (Formerly Sec. 29-77). (Note: This section is repealed, effective January 1, 2013.) Hazardous chemicals. Definitions. As used in sections 29-336 to 29-341, inclusive, "hazardous chemicals" means any materials 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 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; and shall include such materials as compressed gases, liquefied gases, flammable solids, corrosive liquids, oxidizing materials, potentially explosive chemicals, highly toxic materials and poisonous gases. "Compressed gas" means any mixture or material having in the container either an absolute pressure exceeding forty pounds per square inch at seventy degrees Fahrenheit, or an absolute pressure exceeding one hundred four pounds per square inch at one hundred thirty degrees Fahrenheit, or both; or any liquid flammable material having a vapor pressure exceeding forty pounds per square inch at one hundred degrees Fahrenheit. "Corrosive liquids" means 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 are liable to cause fire when in contact with organic matter or with certain chemicals. "Flammable solid" means 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. "Highly toxic materials" are materials so toxic to man as to afford an unusual hazard to life and health during fire fighting operations, including parathion, malathion, TEPP (tetraethyl phosphate), HETP (hexaethyl tetraphosphate), and similar insecticides and pesticides. "Oxidizing materials" means substances such as chlorates, permanganates, peroxides or nitrates, which yield oxygen readily to stimulate combustion. "Poisonous gas" means and includes any noxious gas of such nature that a small amount of the gas when mixed with air is dangerous to life, including chlorpicrin, cyanogen, hydrogen cyanide, nitrogen peroxide and phosgene. "Potentially explosive chemical" means any chemical substance, other than one classified as an explosive, which can be exploded by heat or shock when it is unconfined and unmixed with air or other materials. "Vapor pressure" means the pressure, measured in pounds per square inch (absolute), exerted by a volatile liquid as determined by the nationally recognized good practice known as the Reid method.

      History: 1967 act excluded radioactive materials from definition of "hazardous chemicals" where previously such materials were included in the definition; Sec. 29-77 transferred to Sec. 29-336 in 1983; P.A. 83-566 eliminated from the definition of hazardous chemicals, materials not otherwise defined in Secs. 29-320, 29-343 and 43-36; P.A. 09-177 repealed section, effective January 1, 2011; P.A. 10-54 changed effective date of P.A. 09-177, S. 25, from January 1, 2011, to January 1, 2013, effective May 18, 2010.
