Section 9.02 - Dangerous Articles
Current through Register 1531, September 27, 2024
The following shall constitute dangerous articles: explosives, flammable liquids, flammable solids, oxidizing materials, corrosive liquids, compressed gases, poisonous substances and radioactive materials as hereinafter defined.
Dangerous articles shall also mean any non-flammable compressed gas which is poisonous or lachrymatory to human beings or which has an irritating, asphyxiating or toxic effect when breathed in small concentrations.
(1) Explosives. Any chemical compound or mechanical mixture that is commonly used or intended for the purpose of producing an explosion and which contains any oxidizing and combustible units or other ingredients in such proportions, quantities or packing that an ignition by fire, by friction, by concussion, by percussion or by detonation of any part of the compound or mixture may cause such a sudden generation of highly heated gases that the resultant gaseous pressures are capable of producing destructible effects on contiguous objects or of destroying life or limb.
(2) Flammable Liquid. Any liquid which gives off flammable vapors (as determined by flash point from Tagliabue's open cup tester, as used for test of burning oils) at or below a temperature of 200°F.
(3) Flammable Solid. Any substance, other than an explosive, which is liable under conditions incident to transportation to cause fires through friction, through absorption of moisture, through spontaneous chemical changes, or as a result of retained heat from the manufacturing processing.
(4) Oxidizing Material. Any substance such as chlorate, permanganate, peroxide or a nitrate that yields oxygen readily to stimulate the combustion or organic matter.
(5) Corrosive Liquid. Any acid, alkaline caustic liquid or other corrosive liquid which when in contact with living tissue will cause severe damage of such tissue by chemical action; or in the case of leakage will materially damage or destroy other materials by chemical action: or are liable to cause fire when in contact with organic matter or with certain chemicals.
(6) Compressed Gases. Any material or mixture having in the container either an absolute pressure exceeding 40 pounds per square inch at 70°F, or an absolute pressure exceeding 104 pounds per square inch at 130°F or both: or any liquid flammable material having a Reid* vapor pressure exceeding 40 pounds per square inch absolute at 100°F.
(7) Poisonous Substances. Liquids and gases of such nature that a very small amount of the gas or vapor of the liquid, mixed with air is dangerous to life: or such liquid or solid substances as upon contact with fire or when exposed to air give off dangerous intensely irritating fumes: or substances which are chiefly dangerous by external contact with the body or by being taken internally.
(8) Radioactive Material. Any material or combination of materials that is capable of spontaneous emission of ionizingradiation.
