Code of Massachusetts Regulations › 720 CMR - DEPARTMENT OF HIGHWAYS › Title 720 CMR 9.00 - Rescinds › Section 9.02 - Dangerous Articles

Current through Register 1525, July 5, 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.
